12 SentinelOne Competitors and Alternatives in 2026

What follows covers what SentinelOne includes at each tier, what independent testing shows as of August 2026, 12 alternatives with their real limitations attached, and how to run a proof of concept that produces a decision instead of a demo.

The bottom line

If you only read one section, read this one. Each vendor is profiled in full further down.

• Heimdal. For organizations whose real exposure is email, DNS, unpatched software, and over-privileged users rather than endpoint detection depth, and who want fewer agents and fewer vendors.
• SentinelOne. For teams whose actual gap is endpoint detection depth, with the analyst hours to run a demanding console and the budget to fund retention beyond the default window.
• CrowdStrike Falcon. For large enterprises that want the deepest detection and hunting capability available and can absorb both the price and the operational sophistication.
• Microsoft Defender for Endpoint. For organizations already committed to Microsoft 365 E5, where the marginal license cost is close to zero.
• Palo Alto Cortex XDR. For enterprises already running Palo Alto firewalls and consolidating toward XSIAM.
• Bitdefender GravityZone. For buyers who want top-tier independently measured prevention at better economics than the market leaders.
• ESET PROTECT. For the lightest independently measured endpoint footprint, and for buyers who need an EU-headquartered vendor.
• Sophos Intercept X. For mid-market teams that want balanced protection with a mature managed detection service attached.
• Trend Micro Vision One. For organizations that want email and endpoint telemetry correlated natively, particularly in APAC.
• Cybereason. For security-mature teams that care most about investigation efficiency and attack narrative context.
• ThreatDown. For small teams wanting low-overhead endpoint protection with rollback and emerging identity coverage.
• WatchGuard EPDR. For zero-trust application control, especially alongside existing WatchGuard network appliances.
• Huntress. For small estates that want experienced humans watching rather than another console to learn.

Here’s how the leading SentinelOne alternatives compare at a glance.

The comparison has moved on from detection rates

For most of the last decade, EDR buying was a detection argument. Which engine catches more, which one catches it faster, which one produces the prettiest process tree. In 2026 that argument mostly ends in a draw.

In the AV-Comparatives Endpoint Prevention and Response test of 2025, all 10 certified vendors scored above 95% on both active response and passive response, with individual scores at the certification threshold ranging roughly 95% to 100% depending on the metric and vendor. Differentiation appeared in operational accuracy cost and workflow delay rather than raw coverage.

Several vendors also publish their own readings of MITRE ATT&CK Evaluations data claiming 100% detection, and those readings are vendor analyses rather than lab findings, because MITRE publishes no score and no ranking at all.

Where the numbers still diverge sharply is in the two places that decide whether a deployment survives contact with a real estate.

False alarms. In the AV-Comparatives Business Security Test run between August and November 2025, protection rates clustered between 98.0% and 100% across the mainstream vendors. False alarm counts over the same 461 test cases ranged from zero to 20. That is a tenfold spread among products with near-identical protection. The same pattern repeats across the other tested vendors, which is why the number to ask a vendor for isn’t detection rate but alerts per 1,000 endpoints per week in a tuned steady state.

System impact. In the AV-Comparatives Performance Test of June 2025, measured system impact ran from 4.8 at the lightest to 39.8 at the heaviest among mainstream business products. Roughly an eightfold difference, independently measured, on the same hardware.

The four acronyms, quickly

Buyers get sold across these four constantly, so it helps to be precise.

Three things follow.

EPP and EDR are layers, not alternatives. Almost everything sold as EDR today has a prevention layer underneath it. The distinction survives mainly in how vendors gate their tiers.

XDR is a scope expansion, not a technology generation. There is one question that separates a real correlation engine from a console with tabs. Does an email-delivered threat, the domain lookup it triggers, and the process it spawns arrive as one incident, or as three alerts in three places? Ask it during the demo and watch what happens.

MDR is an operating model. It can be layered on top of almost any EDR. The question that matters is what the provider is contractually permitted to do to your endpoints at three in the morning without waiting for you to reply.

What the consolidation trend actually means for you

Standalone EDR is being absorbed into XDR and into wider security operations platforms. You can see it in the portfolios rather than in the marketing. CrowdStrike has NG-SIEM, Palo Alto has XSIAM, SentinelOne has Singularity Data Lake, and the same vendors have all extended sideways into identity, cloud posture, and exposure management.

Underneath that sits a quieter shift. Organisations have started counting endpoint agents as a purchasing criterion in its own right. “We replaced four tools with one” is a persuasive internal argument in 2026 in a way it simply wasn’t in 2021.

So the genuine question in front of most buyers comparing SentinelOne alternatives isn’t which product detects better. It is closer to this. Do I want the deepest endpoint detection engine available, or do I want fewer vendors, fewer agents, and fewer consoles? Those are different purchases, and treating them as the same one produces bad advice.

Where the traditional approach falls short

Agent Fatigue. Agent sprawl is usually described as a technical problem, and it is one. Multiple privileged agents contending for CPU, memory, and disk I/O is a recurring complaint, and published detection guidance increasingly flags a stack of privileged agents on a single host as a risk indicator in its own right, because each one is a code path running with high privilege that an attacker can abuse. The AV-Comparatives performance data above puts real numbers on the footprint side of that.

The half of the problem that rarely makes the business case is the human half. Every additional agent is another console somebody has to check in the morning, another update cycle to track, another policy model to learn, another alert stream to triage, and another vendor to chase when something breaks. That load compounds faster than headcount does. A team of four doesn’t become a team of eight because the estate now runs eight tools.

The measured pain backs this up. The 2025 SANS Detection and Response Survey reports that 73% of organizations name false positives as their number one threat detection challenge, and the same survey body indicates that 85% of respondents rely on endpoint security alerts as the primary trigger for response. Endpoint noise isn’t a peripheral irritation. It is the main input queue of the security operation.

Tuning never ends. Tuning is sold as a setup task and behaves as a standing operational cost. Many organizations report that alert tuning and custom rule design is their primary method of reducing alert load, and that the burden is significant enough to push them either toward lower-operations products or toward a managed service.

Retention is a security control, not a storage line. If an intrusion is discovered 40 days in and the platform holds 14 days of telemetry, the investigation is crippled before it starts. Retention is the most consistently under-scoped element of an EDR purchase, and it is the one that gets discovered after signature rather than before.

Endpoint-only tools watch the consequence. Email remains among the most common initial access vectors. DNS and web remain among the most common command-and-control channels. Credential-based attacks increasingly bypass the endpoint entirely, which is why nearly every vendor in this set launched identity threat detection capability during 2025 and 2026. An endpoint agent sees what happened after the door opened.

How we think about this at Heimdal

We are the publisher of this article, so treat this section as our argument rather than as neutral analysis. We have tried to make it one you can check.

We don’t claim to detect better on the endpoint than SentinelOne. There is no independent evidence that would support that claim, and it wouldn’t survive your technical evaluation anyway. Our argument is a scope argument, and it stands on its own.

We cover the surfaces an endpoint agent can’t see. DNS and web filtering, email security, patch and asset management, and privileged access management are all part of our platform. SentinelOne doesn’t address any of those four. That is verifiable by looking at both product portfolios, and it is the substantive difference between us.

Three ways to buy, not one

Every module we build can be purchased three ways. This matters more than it sounds, because it decides whether you are buying a platform or buying a gap-filler.

• As a standalone product. Any module. DNS Security, Email Security, Privileged Access Management, Next-Gen Antivirus and Firewall, Ransomware Encryption Protection, Patch and Asset Management, and the rest are all available on their own.
• As part of our unified platform. Scale up or down into exactly what you need, all the way to the full stack if that is what you want.
• As a managed service. MDR, MXDR, and Managed ITDR, where our SOC runs it for you rather than you staffing one.

Patch and Asset Management is the easiest example to explain concretely, but it is one example rather than the offer. If you already run a UEM or systems management tool you intend to keep, and your actual gap is third-party patching, patch reporting, and asset visibility, you can buy Patch and Asset Management on its own. It runs alongside what you already have instead of replacing it. The same coexistence logic applies to any other module you pick.

What the unified platform gives you

One agent. One console. One contract.

• Network security. DNS Security for network and endpoint, with Predictive DNS.
• Endpoint security. Next-Gen Antivirus and Firewall with our Extended Threat Protection engine, plus Ransomware Encryption Protection.
• Vulnerability management. Patch and Asset Management across Windows, macOS, Linux, and 350+ third-party applications, plus Infinity Management.
• Privileged access management. PEDM, PASM, and Application Control with AppFencing™.
• Email and collaboration security. Email Security 365, plus Email Security ATP and Fraud Prevention.
• Threat hunting. The Threat-hunting and Action Center, covering estate monitoring and M365 user monitoring.
• Unified endpoint management. Remote Desktop, BitLocker Management, Scripting, USB Control, and PXE Deployment.

The benefit is narrow and practical. When patching sits inside the same platform as detection, applying a patch becomes a response action rather than a recommendation you hand to a different team and chase for a fortnight.

On AI, and what is actually running today

Two of our AI capabilities are live now and have been for some time. Predictive DNS uses AI and ML-driven analysis to identify suspicious destinations and likely attack activity before threats fully materialize. Our AI-powered email fraud prevention uses outlier detection to surface impersonation attempts, CEO fraud, and out-of-character behavior by comparing traffic against normal organizational patterns. Neither is new, and neither is a feature of what comes next.

AI Wingman is a separate cross-platform intelligence layer we are building on top of the platform, delivered in phases. AI Wingman Assist surfaces the right actions and best-practice settings across the dashboard. AI Wingman Triage uses multi-agent systems to help validate incidents and accelerate triage, and is included with the Threat-hunting and Action Center. AI Wingman SOC brings that acceleration into our managed SOC, and is included with TAC plus MXDR.

On independent validation, plainly

We aren’t in the Gartner Magic Quadrant for Endpoint Protection Platforms, and we haven’t participated in the recent MITRE ATT&CK Enterprise evaluations or the AV-Comparatives EPR test. SentinelOne has a 2024 MITRE Enterprise result and a five-year run as a Magic Quadrant Leader. That is a real difference in the independent evidence available, and pretending otherwise would be insulting.

What has changed recently is worth stating. We were named in the Gartner Europe Context Magic Quadrant for Endpoint Protection in May 2026. In August 2026 we were listed as a representative vendor in Gartner’s Market Overview for Workspace Cybersecurity Platforms, alongside vendors including Microsoft, CrowdStrike, and Sophos.

A Market Overview is a different research format from a Magic Quadrant, so read that as a listing rather than a ranking or an endorsement. We are also in an analyst relationship with Forrester and expect a report to publish soon.

Our MITRE ATT&CK coverage is publicly mapped on the Tidal Cyber Registry. Search for Heimdal and you can see exactly which attack techniques and sub-techniques we detect and stop, down to the sub-technique level. We haven’t paid to participate in the MITRE Engenuity Evaluations, which are a vendor-funded program.

Our coverage is transparent and independently verifiable at any time. Pull the mapping into your proof of concept scorecard and compare it directly against SentinelOne and anyone else on your shortlist.

Practical buyer guidance

Do you actually need to replace SentinelOne?

Sometimes the honest answer is no. Switching EDR is real work, and it is the most common reason organizations stay with an incumbent they are unhappy with. Uninstalling one agent and deploying another across a fleet takes time, and co-existence during migration can cause conflicts.

Signs you probably should move:

• The tier you bought doesn’t include EDR, and the tier that does breaks the budget.
• Retention is shorter than your realistic investigation window and extending it means a tier upgrade or a data lake purchase.
• Your team spends more time tuning than investigating.
• The renewal quote has moved so far from year one that the business case has changed.
• Your actual incidents keep starting in email, in an unpatched application or with a credential, and the endpoint tool only ever tells you afterwards.

Signs you should probably stay and renegotiate instead:

• You have detection engineers writing your own rules and they are productive.
• Endpoint telemetry depth is the thing you genuinely trade everything else for.
• Your open incidents are being caught, and your complaint is commercial rather than technical.

What no EDR will fix

• Unpatched software. Detection isn’t remediation. If the patch never lands, the exposure never closes.
• A missing identity strategy. Credential attacks that use valid logins produce very little endpoint noise by design.
• Nobody reading the alerts. An unmonitored console is a compliance artifact, not a control.
• Compliance by itself. Neither NIS2 nor DORA names EDR. ENISA’s NIS2 technical implementation guidance requires measures covering incident handling and effectiveness assessment, and DORA emphasizes multi-layered detection, alert thresholds, and automated notification to response teams. EDR and XDR are how most in-scope organizations evidence those requirements, but any vendor claiming their product makes you compliant is overclaiming.

How to run a proof of concept that tells you something

Run it on real endpoints running real line-of-business software, for two to six weeks, on 20 to 100 machines. Clean virtual machines will tell you nothing you didn’t already know.

Then ask these, and get the answers in writing:

• What is the alert volume per 1,000 endpoints per week once tuned? Almost no vendor volunteers this figure.
• What retention is included, and what does an additional 60 days cost?
• Which capabilities are absent from the tier you are being quoted? Ask it that way round.
• What are the year-two and year-three prices, written into the initial contract rather than discovered at renewal?
• If a managed service is involved, what will the provider do without waiting for your approval, and what is the response SLA?
• What is the feature parity across Windows, macOS, and Linux? Don’t assume it exists.
• Did the vendor participate in the most recent independent evaluation round, and if not, what current evidence can they offer instead?

The objections worth thinking through honestly

“Nobody gets fired for buying the leader.” Reasonable, and worth respecting. The useful reframe isn’t to attack the leader’s quality but to ask leader in what. The best endpoint detection engine and the best fit for a five-person IT team are different questions with different answers.

“The cheaper option is cheaper because it is worse.” Sometimes true. Where independent test data exists, cite it and check it. Where it does not, a vendor saying so plainly is more trustworthy than one making a claim you can’t verify.

“We will just use Microsoft, it is included.” In the mid-market this is the strongest competitive pressure in the category, and it is genuinely strong. Microsoft’s independent numbers are good and the marginal cost inside E5 is close to zero. The honest counter-considerations are non-Windows coverage, Windows-limited web filtering, license-tier confusion, and the concentration risk of buying your platform and its security from the same vendor.

SentinelOne, the baseline you are comparing against

What it is. An autonomous, AI-driven EDR and XDR platform built on a single agent, with behavioral detection, Storyline attack reconstruction, and automated remediation including rollback. Gartner named SentinelOne a Leader in its 2025 Magic Quadrant for Endpoint Protection Platforms, the fifth consecutive year, as announced by SentinelOne.

The tier map, which is the most useful thing to understand before you renew

Two consequences matter.

Core and Control don’t deliver EDR in any meaningful sense. An organization that believes it bought “SentinelOne EDR” at the Core price bought next-gen antivirus. This is the single most common scoping error in the category.

Retention is the structural constraint. 14 days at Complete is short against realistic attacker dwell times, and extending it means moving to Commercial or buying data lake capacity. The retention figures above are consistently reported across independent sources, and packaging changes, so verify them directly at quote stage.

Strengths. Strong behavioral detection with autonomous on-agent response, so kill, quarantine, and rollback execute at the endpoint without a cloud round trip. Storyline reconstruction is well regarded by practitioners for investigation quality.

A single agent and unified console spanning endpoint, cloud workloads, and identity. User satisfaction is genuinely high, at roughly 4.7 out of 5 on G2 and 4.7 to 4.8 on Gartner Peer Insights across roughly 2,900 to 3,100 ratings as of 2026, effectively level with CrowdStrike. The business is substantial, reporting revenue of $1,001.3M for fiscal year 2026 ended 31 January 2026, up 22%, with ARR of $1,119.1M and 1,667 customers at $100,000 or more in ARR.

Trade-offs. Scope is endpoint, cloud workload, and identity, so email security, DNS and web filtering, patch management, and privileged access management come from other vendors. Capability gating is aggressive, as the tier map shows.

Independent evidence is a cycle old, because SentinelOne doesn’t appear on the published participant list for MITRE ATT&CK Enterprise 2025 or among the AV-Comparatives EPR 2025 certified vendors, making the 2024 MITRE round its most recent Enterprise result. Recurring themes in reviews include console complexity and a steep learning curve, particularly for smaller and IT-led teams, plus mixed support feedback where a persistent minority report slow ticket handling before escalation.

Renewal repricing is the most consistently reported commercial complaint and a common trigger for competitive evaluation. Users also report that rollback works best on Windows filesystem changes and depends on policy configuration, sufficient telemetry, and storage, so it isn’t the universal one-click undo that marketing can be read to imply.

On the financial picture, stated neutrally, SentinelOne reported a GAAP net loss of $450.7M for fiscal 2026 against $288.4M for fiscal 2025, while improving on a non-GAAP basis, with growth decelerating from 32% to 22% and guidance implying around 20% for fiscal 2027.

At $1.1B in ARR this isn’t a viability concern. Growth-stage vendors under margin improvement pressure do commonly pursue price realization in the installed base, which is consistent with what customers report at renewal.

Pricing. SentinelOne publishes self-serve list prices for very small estates. For larger ones, published figures vary widely in reliability. Singularity Complete’s list price is most consistently corroborated at roughly $179.99 per endpoint per year, matching SentinelOne’s own packages page and multiple independent pricing aggregators as of August 2026, though lower secondary quotes also circulate without clear sourcing.

Benchmark sources separately indicate negotiated enterprise pricing lands materially below list, with discounts commonly cited in the 25% to 45% range. Treat any published figure as a ceiling for small deployments and get a quote for your actual endpoint count.

Best for. Mid-market to enterprise organizations with a functioning security team that want strong autonomous endpoint detection, value on-agent automation, and either have short investigation windows or budget for extended retention. A weaker fit for IT-led teams seeking minimal operational overhead, and for organizations whose real exposure is email, DNS, patching or privilege.

1. Heimdal

What it is. Our unified security platform, built in Copenhagen since 2014, delivering more than 10 modules through one agent and one console. Every module can be bought on its own, as part of the platform, or run for you as a managed service.

Best for. Mid-market and enterprise organizations that need to cover several attack surfaces with a small team, that place real value on reducing vendor and agent count, and whose realistic alternative isn’t operating a mature in-house SOC.

Key strengths.

• Scope SentinelOne doesn’t cover. DNS and web filtering, email security, patch management, and privileged access management sit inside the same platform. This is a vendor-count and agent-count argument, not a feature-count one.
• Patching as a response action. Because Patch and Asset Management is in the platform, closing the exposure is something the responder can do rather than something they file a ticket about. Coverage runs to Windows, macOS, Linux, and 350+ third-party applications.
• DNS-layer prevention. Blocking command-and-control at DNS resolution interrupts the chain before endpoint execution, which is earlier than an endpoint-only tool can act.
• Privilege management built in. PEDM removes standing local admin rights and handles just-in-time elevation with a full audit trail, and it de-escalates automatically on threat detection. PASM adds account discovery, a credential vault, and session monitoring with recording and playback. Application Control with AppFencing™ handles execution control and the spawning of child processes, and it can be tied directly to the PAM layer.
• Detection context. Our Extended Threat Protection engine ships 1,400+ curated detection rules with MITRE ATT&CK-aligned classification, feeding the Threat-hunting and Action Center where quarantine, isolation, scan, and block run from a single action pane.
• Packages that map to how people buy. NDR, EDR, MDR, XDR, MXDR, and ITDR are pre-built bundles, and you can build your own instead.
• EU jurisdiction. Danish headquarters and EU data handling, which matters for NIS2-scope entities and European public sector procurement.

Trade-offs.

• Endpoint detection depth isn’t our strongest axis. If maximum endpoint telemetry depth and long retention for a dedicated detection engineering function is the requirement, SentinelOne and CrowdStrike are built for that and we are not.
• Our independent test coverage is thinner. We didn’t participate in MITRE ATT&CK Enterprise 2024 or 2025, nor in AV-Comparatives EPR 2025. Our MITRE ATT&CK coverage is published on the Tidal Cyber Registry instead, and it is verifiable at any time.
• We aren’t in the Gartner EPP Magic Quadrant. We were named in the Gartner Europe Context Magic Quadrant for Endpoint Protection in May 2026, and listed as a representative vendor in Gartner’s Market Overview for Workspace Cybersecurity Platforms in August 2026. Those are different research formats and we would rather you knew that than assumed a ranking.
• We don’t publish headcount or revenue. If vendor scale disclosure is a hard procurement requirement, ask us directly during diligence.

Pricing. Use our pricing calculator. Pick your modules and endpoint count and you get an instant estimate on the page and by email, without a sales conversation first.

2. CrowdStrike Falcon

What it is. The enterprise detection benchmark, combining a lightweight single agent with a very large threat intelligence dataset and a mature managed hunting service.

Best for. Large enterprises and security-mature mid-market organizations that prioritize maximum detection and hunting capability and can absorb both the cost and the operational sophistication required.

Key strengths. CrowdStrike announced that Gartner named it a Leader in the 2025 Magic Quadrant for Endpoint Protection Platforms, positioned highest on Ability to Execute and furthest on Completeness of Vision for the third consecutive year. It participated in MITRE ATT&CK Enterprise 2025 and states it achieved 100% detection, 100% protection, and zero false positives, which is CrowdStrike’s own reading of the raw data rather than a lab score, since MITRE publishes no scores.

It is certified in AV-Comparatives EPR 2025, scoring 97.3% active response and 98.0% passive response. OverWatch managed hunting and Falcon Complete MDR are well regarded. Reported ARR passed $5B in fiscal 2026 and reached $5.84B by the second quarter of fiscal 2027.

Trade-offs. Premium pricing, frequently the highest per endpoint in a competitive set, with modular licensing that compounds total cost.

The platform and the NG-SIEM console are heavy for small teams. In the AV-Comparatives Business Security Test of August to November 2025, CrowdStrike recorded 20 false alarms, the highest among the mainstream vendors in that cohort, against 2 for Microsoft and 2 for Bitdefender at comparable protection rates.

The contrast with its own zero-false-positive MITRE claim is instructive, because different tests measure false positives against very different workloads, and that is exactly why single-test claims shouldn’t be generalized. Measured system impact was 26.2 in the June 2025 performance test. The July 2024 global outage is still raised by buyers as a concentration-risk consideration. Built-in data loss prevention is limited.

Pricing. Undisclosed for enterprise deployments. Quote-based, and consistently reported at the premium end.

3. Microsoft Defender for Endpoint

What it is. The default endpoint platform for Microsoft-centric estates, integrated natively with Sentinel, Entra, and the wider Defender stack.

Best for. Organisations committed to Microsoft 365 E5 or equivalent, particularly where license efficiency outweighs best-of-breed detection.

Key strengths. Often effectively zero incremental cost inside an E5 bundle, which is the single most powerful commercial argument in the category. Microsoft announced it was named a Leader in the 2025 Gartner EPP Magic Quadrant for the sixth consecutive time. The independent numbers are strong, with 99.1% protection and only 2 false alarms in the AV-Comparatives Business Security Test of August to November 2025, 100% malware protection, and light measured system impact at 13.8 in the June 2025 performance test.

Very large telemetry base across Office 365, Entra, and Azure. IDC’s revenue-based estimates for modern endpoint security put Microsoft’s share in the high-20s percent as of 2024, its most recently published figure, driven largely by Microsoft 365 bundling. Seat-count and install-base estimates vary far more widely across data providers, so treat any single share figure as directional rather than definitive.

Trade-offs. Web filtering is substantially Windows-limited. A heavy Linux agent and less granular anti-malware policy customization than specialist tools show up again and again in reviews. Licensing complexity is significant, because which Defender capabilities you actually hold depends on which Microsoft 365 or standalone SKU you bought, and that is a frequent source of confusion. Microsoft didn’t participate in MITRE ATT&CK Enterprise 2025 or AV-Comparatives EPR 2025.

A weaker fit for heterogeneous estates or where non-Windows coverage is significant.

Pricing. Bundled within Microsoft 365 E5, or available standalone. Cost depends entirely on your existing licensing position, so model it against what you already pay rather than against a per-endpoint list price.

4. Palo Alto Cortex XDR

What it is. An XDR-first platform where the endpoint is one sensor alongside firewall, cloud, identity, and SIEM, feeding toward XSIAM.

Best for. Large enterprises with an existing Palo Alto footprint pursuing platform consolidation.

Key strengths. Genuine cross-domain correlation and incident stitching, particularly where the customer already runs Palo Alto next-generation firewalls and Prisma. Certified in AV-Comparatives EPR 2025. Palo Alto announced Gartner named it a Leader in the 2025 EPP Magic Quadrant for the third consecutive year.

It states it achieved 100% technique-level coverage in the 2024 MITRE round with no delays or configuration changes and blocked eight of nine assessed attack steps in prevention, which again is the vendor’s own reading rather than a MITRE score. Built-in vulnerability assessment and Unit 42 threat intelligence.

Trade-offs. Complexity and a steep learning curve are the criticism that comes up most, covering the interface, policy management, tuning, and onboarding. Pricing is premium and non-transparent, and the value case leans heavily on already owning Palo Alto infrastructure. The third-party integration catalog is narrower than CrowdStrike’s or SentinelOne’s, and cross-operating-system feature gaps are reported. Didn’t participate in MITRE ATT&CK Enterprise 2025. A poor fit as standalone EDR for smaller or non-Palo Alto estates.

Pricing. Undisclosed. Quote-based, and reported as premium.

5. Bitdefender GravityZone

What it is. A broad endpoint platform combining NGAV, EDR, and XDR with sandboxing, patch management, risk analytics, and email and web security, from a Romania-headquartered vendor.

Best for. Organisations wanting top-tier independently measured prevention plus competent EDR at better economics than the market leaders, with the administrator capacity to learn a deep product.

Key strengths. The independent test record is the strongest argument here. Certified in AV-Comparatives EPR 2025 with 100% active and passive response, no operational accuracy issues, and no workflow delays. In the August to November 2025 Business Security Test it achieved 99.8% real-world protection with only 2 false alarms.

Third-party summaries of the 2025 Gartner EPP Magic Quadrant report Bitdefender as the sole Visionary, which is reported second-hand rather than confirmed by a Bitdefender announcement. Bitdefender states it recorded the highest detection rate among EPR participants and the lowest five-year total cost of ownership, and it is useful to know that Palo Alto Networks and ESET publish competing leadership claims drawn from the same test using different sub-metrics.

Flexible cloud or on-premise deployment. EU headquarters, relevant for data sovereignty.

Trade-offs. Recurring themes in reviews include a steep learning curve for the advanced EDR and XDR features, higher resource usage during full scans, narrower macOS capability than Windows, and confusing reporting for some administrators. Measured system impact of 32.8 in the June 2025 performance test places it toward the heavier end of the tested set. Didn’t participate in MITRE ATT&CK Enterprise 2025.

Pricing. Undisclosed for business tiers. Quote-based, and priced below the market leaders on total cost.

6. ESET PROTECT

What it is. A lightweight endpoint platform with strong baseline protection, with EDR and XDR delivered through Inspect and a managed detection service layered above. Slovakia-headquartered.

Best for. Organisations prioritising a light endpoint footprint, strong prevention, and integrated managed detection, particularly in Europe.

Key strengths. The best independently measured performance profile in the category, with a system impact score of 4.8 in the AV-Comparatives June 2025 performance test, roughly three times lighter than the next-best vendor tested. 100% protection in the August to November 2025 Business Security Test with 6 false alarms.

Certified in AV-Comparatives EPR 2025. Participated in MITRE ATT&CK Enterprise 2025. Third-party summaries of the 2025 Gartner EPP Magic Quadrant report ESET as a Challenger, reported second-hand. High user satisfaction on G2’s XDR grid. EU vendor, which matters for sovereignty-sensitive buyers.

Trade-offs. AV-Comparatives has noted less consistent detection for identity-based and Active Directory-level techniques compared with process-level attacks. That is a specific, independently sourced limitation and the one worth weighing, because it matters most for organizations whose primary concern is credential-based attack paths. ESET’s EDR historically required the enterprise tier, which smaller buyers found cost-prohibitive.

The third-party integration catalog is narrower than US-centric platforms.

Pricing. Undisclosed for business tiers. Quote-based through ESET or a partner.

7. Sophos Intercept X and Sophos XDR

What it is. A balanced EPP, EDR, and XDR platform with one of the larger managed detection services attached, sold predominantly through partners.

Best for. Mid-market organizations wanting balanced protection with a mature managed service option at moderate cost.

Key strengths. Sophos announced it was named a Leader in the 2025 Gartner EPP Magic Quadrant for the 16th consecutive report, the longest continuous run in the category. Participated in MITRE ATT&CK Enterprise 2025 and states it detected all 16 attack steps and all 90 sub-steps with technique-level detections on 86 of 90, while transparently noting that this reflects the configuration-change run rather than the initial run.

That disclosure is unusually candid for this kind of claim and worth crediting. Well-regarded root cause analysis and Threat Analysis Center. Sophos MDR is among the larger managed detection offerings by customer count.

Sophos also publishes useful research on how security controls relate to cyber insurance claim outcomes, and the directional finding that carriers increasingly price for detection maturity is corroborated by independent underwriting sources.

Trade-offs. The weakest independent protection score among mainstream vendors in the AV-Comparatives Business Security Test of August to November 2025, at 98.0% with 8 compromised cases, and the heaviest measured system impact in the June 2025 performance test at 39.8. Linux workstation support gaps are reported.

Some EDR capabilities are gated by tier. Predominantly partner-sold, which some direct buyers dislike. Some users report friction with agent deployment and uninstall, particularly on macOS. Not among the AV-Comparatives EPR 2025 certified vendors.

Pricing. Undisclosed. Quote-based, usually through a partner.

8. Trend Micro Vision One

What it is. An XDR platform with genuine breadth across email, endpoint, network, and cloud, with strong regional presence in APAC.

Best for. Medium to large organizations, particularly in APAC or already running Trend Micro email and endpoint, that want integrated XDR rather than best-of-breed endpoint detection.

Key strengths. Email security is a real strength and is natively correlated with endpoint telemetry, which is meaningful given how often intrusions begin in the inbox. Participated in MITRE ATT&CK Enterprise 2025. Broad integration coverage. Strong regional support and compliance alignment in APAC. Third-party summaries of the 2025 Gartner EPP Magic Quadrant report Trend Micro as a Leader, reported second-hand.

Trade-offs. MITRE detection performance is competitive but not leading-edge relative to the top tier. Reviewers keep flagging autonomous response depth and threat-hunting user experience as behind top peers, plus a modular add-on and credits-based commercial model that complicates procurement and cost planning. Not among the AV-Comparatives EPR 2025 certified vendors.

Pricing. Undisclosed. Quote-based, with a credits model that is worth modeling carefully before signing.

9. Cybereason

What it is. An EDR, XDR, and MDR specialist organized around the MalOp concept, which consolidates related activity into a single attack narrative rather than a stream of discrete alerts.

Best for. Security-mature teams that value investigation efficiency and attack narrative context, and are comfortable selecting outside the Leaders quadrant on the strength of their own testing.

Key strengths. Participated in MITRE ATT&CK Enterprise 2025 and states it achieved 100% detection, 100% accuracy, and 100% SOC efficiency without special tuning, which is the vendor’s own reading of MITRE’s raw data rather than a published score. MalOp contextualization is well regarded for reducing investigation time. Reviewers consistently praise low false positive rates and a responsive sensor.

Trade-offs. Materially smaller market presence and partner network than the Magic Quadrant Leaders, and not placed in the Leaders quadrant of the 2025 EPP MQ. The global support footprint is less established. Fewer platform-adjacent capabilities such as SIEM and cloud posture management than the largest vendors. Standard vendor viability diligence applies, as it would for any vendor outside the top tier.

Pricing. Undisclosed. Quote-based.

10. ThreatDown (Malwarebytes)

What it is. SMB and mid-market focused EDR and MDR. ThreatDown is the rebranded Malwarebytes business unit, so the two are one vendor rather than two options on your shortlist.

Best for. Smaller organizations wanting straightforward endpoint protection plus managed detection plus emerging identity coverage, without enterprise complexity.

Key strengths. Named EPP Product of the Year 2025 by MRG Effitas, an independent lab recognition rather than a vendor claim. ThreatDown also cites a related Gold Award for attack visibility from a separate lab test on its own materials. Participated in MITRE ATT&CK Enterprise 2024.

According to product documentation it provides three-level isolation and ransomware rollback via its Linking Engine, and launched Identity Threat Detection and Response in 2026 integrating Entra ID, Okta, and Active Directory with endpoint telemetry, delivered within the Ultimate MDR Plus tier. Genuinely low operational overhead is the point reviewers raise most often.

Trade-offs. Not placed in the Gartner EPP Magic Quadrant. Enterprise XDR and SIEM depth and integration coverage sit well behind the platform vendors. Brand perception remains consumer-adjacent within some buying committees, which is a procurement problem rather than a product one. Not among the AV-Comparatives EPR 2025 certified vendors, and didn’t participate in MITRE ATT&CK Enterprise 2025.

Pricing. Undisclosed for business tiers. Contact sales.

11. WatchGuard EPDR and Advanced EPDR

What it is. Combined EPP and EDR built on Panda Adaptive Defense heritage, with a Zero-Trust Application Service that classifies every executable before it is permitted to run.

Best for. Mid-market organizations wanting integrated EPP and EDR with zero-trust application control, particularly those already running WatchGuard network appliances.

Key strengths. Participated in MITRE ATT&CK Enterprise in both 2024 and 2025. Named a Leader and Outperformer in GigaOm’s 2025 EDR Radar. The Zero-Trust Application Service is a genuinely differentiated architecture rather than a marketing label, because classifying every binary before execution is a different control model from behavioral detection after the fact. Competitive value for small and mid-size fleets. Unified management alongside WatchGuard firewalls.

Trade-offs. Not placed in the Gartner EPP Magic Quadrant. Threat-hunting depth and integration breadth are smaller than the Leaders. Reporting and console capabilities are still maturing relative to top-tier EDR platforms, reviewers say.

Pricing. Undisclosed. Quote-based, usually through a partner.

12. Huntress

What it is. Managed EDR and MDR built for small estates, pairing a lightweight agent with 24/7 human threat hunting.

Best for. Small organizations that want high-touch managed detection rather than building internal capability. This is a notable omission from most SentinelOne alternatives lists and one of the more credible options at the small end of the market.

Key strengths. As of 2026, Huntress holds approximately 4.9 out of 5 on G2 across roughly 800 to 900 reviews, among the highest-rated managed detection offerings on that platform. The response model is genuinely different, because analysts telephone customers during incidents rather than only raising a ticket. Strong behavioral detection with low false positive rates comes up again and again in reviews. Pricing and service model are tuned to small budgets.

Trade-offs. Not placed in the Gartner EPP Magic Quadrant, because it sits below the inclusion threshold and is fundamentally a managed service rather than a broad EPP platform. It hasn’t participated in the recent MITRE ATT&CK Enterprise rounds or AV-Comparatives EPR. Limited advanced threat-hunting tooling for an internal SOC. Reviews cite narrower macOS capability relative to Windows, and limited customization.

Pricing. Undisclosed publicly for most configurations. Quote-based, positioned aggressively at the small end.

Comparison at a glance

Which one, by situation

You have a SOC and detection engineers writing your own rules. Stay with SentinelOne or look at CrowdStrike. Endpoint telemetry depth, query language quality, and retention economics are what you are buying, and both are built for it. Model three years of retention cost before you compare headline prices.

You are five people covering IT and security for 2,000 endpoints. Operational burden is the deciding criterion, not detection rate. Look at Heimdal for breadth per agent, at Sophos or Huntress if you want the watching done for you, or at ESET if endpoint footprint is your constraint.

You are fully committed to Microsoft 365 E5. Model Defender for Endpoint honestly before anything else. The independent numbers are good and the marginal cost is close to zero. Then check your non-Windows coverage and decide whether the concentration risk is acceptable to your board.

Your incidents keep starting somewhere other than the endpoint. If phishing, unpatched software, and over-privileged users are what actually bites you, a deeper endpoint engine will keep telling you about it slightly faster rather than stopping it. Look at platforms that cover email, DNS, patching, and privilege in the same purchase.

You are in scope for NIS2 or DORA and jurisdiction matters. ESET, Bitdefender, WithSecure, and Heimdal are EU-headquartered. Confirm data residency, processing location, and retention against what your regulator expects, which is frequently longer than an EDR’s default window.

Your complaint is the renewal quote, not the product. Get competitive quotes and reopen the conversation. That is a legitimate outcome of this exercise, and a competitive quote is worth more in a negotiation than a complaint is. Ask for year-two and year-three prices in writing this time.

You have under 200 endpoints. Direct enterprise EDR is usually the wrong shape. Managed offerings will serve you better, and Huntress and ThreatDown are built for that end of the market.

Frequently asked questions

Is SentinelOne an EDR or an XDR?
Both, depending on the tier. Singularity Core and Control are prevention-focused endpoint protection without meaningful EDR capability. Singularity Complete is the first tier with full EDR and XDR, including Storyline forensics, deep visibility, and SIEM integration. SentinelOne’s scope extends beyond the endpoint to cloud workloads and identity, so describing it as “just an EDR” is inaccurate. What it doesn’t cover is email security, DNS and web filtering, patch management, and privileged access management.

What is the difference between EDR and XDR?
EDR detects, investigates, and responds using endpoint telemetry. XDR correlates that endpoint telemetry with email, identity, network, and cloud signals so related activity becomes one incident instead of several alerts. The practical test is whether an email-delivered threat, the domain lookup it triggers, and the process it spawns arrive as one incident or as three separate alerts in three places.

How much does SentinelOne cost?
There is no reliable public figure for anything beyond very small estates. Third-party aggregators contradict each other by nearly a factor of two on the same SKU, and negotiated enterprise pricing is reported to land materially below list, with discounts commonly cited between 25% and 45%. Get a quote for your actual endpoint count, and ask specifically what the year-two and year-three prices are.

How long is SentinelOne’s telemetry retention?
Singularity Complete is commonly documented as including 14 days, with Singularity Commercial commonly documented at around 90 days. Packaging changes, so verify at quote stage. Compare whatever number you get against the dwell time you would realistically need to investigate, because retention functions as a security control rather than a storage line item.

Which SentinelOne alternative is best for a small IT team?
It depends on which problem is biggest. If it is too many consoles and too many vendors, a broad platform reduces the surface you have to operate. If it is nobody available to watch alerts, a managed detection service is the honest answer rather than a better console. If it is endpoint performance on older hardware, ESET has the lightest independently measured footprint in the category.

Is switching EDR worth the disruption?
Only if the reason is structural. Uninstalling one agent and deploying another across a fleet is real work, and co-existence during migration can cause conflicts. If your complaint is commercial, a competitive quote may solve it without a migration. If the tier you own doesn’t include the capability you thought you bought, or your retention window can’t support an investigation, that is structural and worth the disruption.

Do MITRE ATT&CK Evaluation percentages mean anything?
MITRE publishes raw per-substep results and no score or ranking of any kind. Every percentage figure you see is a vendor’s own aggregation using its own definition of what counts as a detection. Read the raw evaluation for the vendors on your shortlist, and treat any vendor-published comparison chart of competitors’ results as marketing.

What does a vendor’s absence from a lab test tell me?
Less than it appears to. Participation in MITRE ATT&CK Evaluations and AV-Comparatives EPR is voluntary and paid for by the vendor, and vendors skip rounds for reasons including cost, scheduling, and product transitions. It does tell you how current the independent evidence for that product is, which is a fair thing to ask about. If a vendor didn’t participate, ask what current evidence they can offer instead, and whether their ATT&CK coverage is published anywhere you can inspect it.

Does EDR make us NIS2 or DORA compliant?
No product does. Neither regulation names EDR. ENISA’s NIS2 technical implementation guidance requires measures covering incident handling and effectiveness assessment, and DORA emphasizes multi-layered detection, alert thresholds, and automated notification to response teams. EDR and XDR are how most in-scope organizations evidence those requirements, but the evidence is the deployment, the process, and the records, not the license.
