See protection in action.

Watch how Heimdal monitors your endpoints in real time, flags suspicious behaviour, and responds before damage spreads, without a single manual intervention from your team.

Key Features

Everything a small business needs to stop a breach. Nothing that requires a security team to run.

You can't watch every endpoint. Heimdal does it for you.

Most small businesses find out they were breached weeks after the fact. By then, the damage is done. In many ransomware incidents, the backups turn out to be encrypted too. Heimdal monitors every endpoint continuously, correlating behaviour across your estate against Indicators of Compromise and Indicators of Attack. When something looks wrong, it acts: device isolation, user access revocation, process blocking, file quarantine, and malware removal happen automatically. It responds to real threats, not false positives, so your inbox stays clear. Whether you are managing 50 machines or recovering from an incident that exposed gaps in your previous setup, your phone does not ring at 2am because Heimdal already contained the problem.

Many attacks start with a DNS query. Heimdal blocks them there.

Your firewall logs will not show you the DNS query that started the attack. By the time malware executes on an endpoint, it has already contacted its command-and-control server. That communication happens at the DNS layer, before any file lands on any machine. Heimdal's DNS Security layer intercepts that request before the connection is made. The threat never reaches the endpoint because it never gets past the network layer. This DNS protection was built from the technology Heimdal developed after winning the DEF CON Capture the Flag competition in 2011, the first non-US team to do so.

You're probably flying blind on which machines are unpatched. That ends here.

Windows Update covers Windows. It does not cover the browsers, PDF readers, remote access tools, and productivity apps your team runs every day. Those are among the most frequently exploited applications in initial access attacks. Heimdal shows you the patch status of every application across every endpoint, in one view. Patches deploy automatically on your schedule. A full audit trail is generated for every update. When your insurer asks about your patch currency, you have the evidence ready.

Too many people have admin rights on your network. That is how ransomware spreads.

Check how many people in your organisation currently have local admin rights. Then check how many of those accounts actually need them. In most small businesses, the number is much higher than it should be, and it climbs every time someone new joins and no one removes access when they leave. Heimdal removes standing admin privileges from endpoints and controls elevation requests in real time. When a user needs temporary admin access, they request it. You approve it. It expires. According to Heimdal's PEDM solution brief, 93% of critical Windows OS vulnerabilities can be mitigated by removing local admin rights. When a compliance auditor or insurer asks for access records, you have the full audit trail ready.

Key benefits

Stop paying for five tools that don't talk to each other.

Most small business IT environments run on a stack that was built by accident. An antivirus here. A patching tool there. Maybe a basic email filter. None of them share intelligence. All of them generate noise. You spend your day triaging alerts instead of running the business. Heimdal replaces that stack with one agent and one dashboard.

One agent. No more juggling.

You stop opening five dashboards and managing five separate alert queues. One deployment replaces the disconnected tools you are currently running separately. Next-Gen Antivirus, DNS protection, ransomware prevention, patch management, and privileged access control work together from a single lightweight agent on each machine. One console. Your users will not notice it running.

Produce the evidence your insurer and auditors are asking for.

Heimdal supports compliance with NIS2, Cyber Essentials, and GDPR through built-in audit trails and documented endpoint controls. When your insurer asks whether you have EDR deployed, or when a supply chain customer asks for your security controls documentation, you have the answer ready.

Stop ransomware before it touches your files.

Backups are not a ransomware strategy. Research cited in Heimdal's Ransomware Encryption Protection brief shows fewer than 14% of organisations can fully restore their data after a ransomware attack. Heimdal detects ransomware behaviour at the encryption stage and blocks it before your files are affected. The threat is contained. The business keeps running.

EDR for Small Business FAQs

What is endpoint detection and response (EDR)?

EDR is a category of security software that monitors endpoints, including laptops, desktops, and servers, for signs of malicious activity. It records what happens on each device and responds when a threat is detected. Unlike traditional antivirus, which blocks known threats based on signatures, EDR uses behavioural analysis to catch activity that looks suspicious even if the specific threat has never been seen before.

What is the difference between EDR and antivirus software?

Antivirus software identifies and blocks known threats using signatures, a database of previously identified malware. EDR goes further. It monitors endpoint behaviour continuously, looking for suspicious activity even from threats that have no signature yet. EDR also records what happens on each device and takes automated response actions when something is detected. Blocking is one function. Visibility, investigation, and containment are the rest.

How does EDR protect against ransomware?

EDR detects ransomware through behavioural indicators: unusual file access patterns, encryption activity, lateral movement, and attempts to reach command-and-control servers. When those patterns appear, it isolates the affected device automatically before other endpoints are hit. Heimdal EDR also blocks command-and-control communications at the DNS layer before ransomware executes, and includes a Ransomware Encryption Protection component that targets the encryption phase specifically.

Does Heimdal EDR work without a dedicated security team or SOC?

Yes. Heimdal EDR is built for environments where one person manages all IT responsibilities. Detection, containment, and response happen automatically. When a threat is identified, Heimdal isolates the device, revokes user access, blocks the process, quarantines files, and removes malware without manual intervention. One dashboard gives you visibility across all endpoints. You do not need a security analyst to run it.

How quickly can Heimdal EDR be deployed across a small business environment?

Heimdal EDR deploys through a single lightweight agent installed on each endpoint. There is no requirement for professional services or complex infrastructure changes to get started. The same console manages environments from 50 to 5,000 endpoints, so the process scales without adding administrative overhead. For a deployment timeline specific to your environment and device count, speak to our team during the demo.

Does Heimdal EDR replace our existing antivirus, or does it run alongside it?

Heimdal EDR includes Next-Gen Antivirus and Firewall as a built-in component, so it replaces your standalone antivirus rather than running on top of it. It also integrates with existing security infrastructure if you have other tools in place. Most small businesses use Heimdal EDR to consolidate separate antivirus, patching, and basic monitoring tools under one agent and one dashboard.

Does Heimdal EDR help us meet NIS2, Cyber Essentials, or GDPR requirements?

Heimdal EDR supports compliance with NIS2, Cyber Essentials, and GDPR by providing documented endpoint controls and automatically generated audit trails. These records cover patch currency, privilege management, and incident response activity. The specific controls that apply to your business depend on your sector and the exact framework requirements. Speak to our team to confirm how the platform addresses your compliance obligations.

What does Heimdal EDR cost for a small business, and how is it priced?

Heimdal EDR is priced per endpoint, which means cost scales with the size of your environment rather than locking you into a fixed enterprise tier. Exact pricing depends on the number of endpoints and the modules included in your package. For a quote tailored to your business, request a demo or contact Heimdal’s sales team directly.
