Features, pricing, ratings, and pros & cons — compared head-to-head.
Filigran OpenAEV is a commercial threat simulation tool by Filigran. Red Team Automation (RTA) is a free threat simulation tool. 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, 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 building detection rules from scratch or validating existing EDR/SIEM logic will find Red Team Automation valuable because it generates working proof-of-concept attacks mapped to MITRE ATT&CK without requiring commercial red team services. The Python framework and 1,090 GitHub stars indicate it's been battle-tested enough to produce realistic artifacts that actually trigger your detection stack. Skip this if your team lacks Python fluency or expects a UI; RTA demands engineers comfortable reading and modifying code to get real value.
