Metta is a free threat simulation tool. Raxis Breach and Attack Simulation is a commercial threat simulation tool by Raxis. Compare features, ratings, integrations, and community reviews side by side to find the best threat simulation fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
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.
Raxis Breach and Attack Simulation
Security teams who need to validate that their controls actually stop real attacks, not just pass checkboxes, should use Raxis Breach and Attack Simulation. Human-led penetration testers run full kill chain scenarios across your entire attack surface,cloud, APIs, networks, physical, social,then measure whether your SOC, EDR, and detection tools catch it. The service maps directly to NIST CSF 2.0 ID.RA and DE.AE functions, meaning you'll know which risks you've actually mitigated versus which ones you've only theoretically addressed. Skip this if your priority is automating away the human labor of security testing; Raxis is staffed, not scaled, and priced accordingly.
