CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise teams with mature EDR deployments will get the most from Filigran OpenAEV because it validates whether your existing detection stack actually catches real attacks instead of just assuming coverage. The platform's MITRE ATT&CK-aligned simulation library and AI-assisted scenario creation mean you're testing threats your environment actually faces, not generic templates, and the agentless architecture lets you start validating immediately without EDR replacement costs. Skip this if you need a turnkey solution that works without an EDR already in place; OpenAEV assumes you own the detection layer and want to stress-test it.
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.
