In a previous article, we talked about the core differences between SOAR and XDR. And because no SecOps specialist should be without an adequate toolkit, here are some SOAR tools you can try out to up your security automation game. Good hunting and enjoy the read!
Best Open Source SOAR Tools
Let’s get started. This list includes tools designed to accommodate all SOAR needs, from security monitoring and IDS/IDP to threat intelligence, vulnerability assessment, and incident response.
1. Heimdal® Threat-Hunting and Action Center (TAC)
Why choose SOAR over SIEM or the other way around when you can have both?
The Heimdal® Threat-hunting and Action Center is a revolutionary platform that is fully integrated with the Heimdal solution suite.
Designed to provide security teams with an advanced threat-centric view of their IT landscape, the solution employs granular telemetry to enable swift decision-making, using built-in hunting, remediation and actioning capabilities – all managed from the Heimdal Unified Security Platform.
Key Features
- Threat Telemetry View Visualizer – ‘the visual storyboard’ an interactable global view of locations, grouped by endpoints/hostname and risk severity
- Risk Scoring – pre-computed trending and analysis by day/month
- Categorized Events – classified by CVSS-spun severity (i.e., Critical, High, Medium, and Low)
- XTP Engine/MITRE Risk Alerts – pre-computed top 5 alerts by MITRE ATT&CK tactics
- MITRE Threat Visualizer – alternative threat-viewing mode, categorized by MITRE alerts.
- Threat Detection – leverages our state-of-the-art XTP Engine which analyses logs using 2k+ rules trained by our experts and mapped to renowned industry techniques (i.e., MITRE) of alerts based on 1400+ sigma rules
- Threat Classification – XTP Engine powered by MITRE classifications does the heavy lifting when it comes to risk classification and threats based on type, empowering security teams to know where the alert originates (e.g., privilege escalation, persistence, execution, credential access, lateral movement, etc.).
- Threat Hunting – dive straight into groups and hosts that have indicators of compromise (IoCs) across the network and track-down IP locations using globe/map view.
- Threat Investigation – drill into endpoint level for advanced intel including health, risk scores, and more; completely visualized to fuel action or further investigate modules.
- Deep Analysis – our threat-engine aids further investigation/forensics efforts with contextualized detection details including process mapping.
- Remediation – deep intel to review, resolve, aid responders or action a response straight from the suite; complete with logged activity trail and notes.
- Action controls – a hot action widget control panel that spans across detection, remediation action log, audit trails, and recommendations.
- Protection Stats Reporting – a real-time at-a-glance widget that indicates risk levels across the Heimdal activate suite, along with health score and trend analysis over a selected period.
2. Velociraptor
Source: Medium
With no relation to Jurassic Park’s iconic fauna member, Velociraptor can best be described as a lightweight but advanced DFIR ( Digital Forensics and Incident Response) platform, enabling a small SecOps team to investigate artifacts, monitor unusual endpoint activity across a vast digital ecosystem, formulate defense strategies, and mitigate incidents such as data breaches.
Key Features
- Customizable artifacts via VQL (i.e. Velociraptor Query Language).
- Ability to create and customize monitoring rules on endpoint or server.
- Investigate disclosure of data occurrences outside of the environment.
- Ability to investigate various devices and flows.

Deployment
Per the official documentation, the easiest way to deploy Velociraptor is through GitHub. However, do bear in mind that this is for evaluation purposes only. The same documentation reveals that Velociraptor’s setup should include three key milestones, along with several in-between steps.
Milestone 1: Server deployment. Three deployment schemes are available: self-signed SSL, cloud deployment, or Instant Velociraptor (see GitHub page).
Milestone 2: Client(s) deployment. Multiple deployment options: interactive setup, custom MSI, Client-as-a-Service, and agentless deployment.
Milestone 3: User authorization.

Conclusion
This wraps up my article on the best open-source tools. Hope you’ve enjoyed it. Before I scoot, I’m going to share with you some things you can try out to get the best out of your SOAR solution.
- Trial and error. There’s nothing wrong with trying out multiple open-source SOAR tools at the same time. It might even give you the edge you need in order to make an educated decision.
- APIs and connectors. Please make sure that the SOAR you choose has the right API connectors. More than that, those connectors must also be customizable.
