CST VerdictBased on our analysis of available product data, here is our conclusion:
Security teams in mid-market organizations with fragmented detection tools will get the most from Infection Monkey because it actually executes lateral movement paths your network allows, forcing you to fix what monitoring alone won't catch. The tool's 6,975 GitHub stars and free model mean you get community-tested propagation logic without licensing friction to run it across your data center. Skip this if you need guided remediation workflows or integration with your existing SIEM; Infection Monkey surfaces the problem clearly but leaves the response architecture to you.
Security teams building an adversarial simulation program on a shoestring budget should start with Metta; it's free and open-source, so you can deploy it immediately without procurement overhead or vendor lock-in. The 1,133 GitHub stars and active community mean you're not betting on abandoned code. Skip Metta if you need polished UI, commercial support, or pre-built scenarios for compliance frameworks; this is a DIY tool that demands engineering resources to customize and operationalize.
