Filigran OpenAEV is a commercial threat simulation tool by Filigran. Pentera RansomwareReady™ is a commercial threat simulation tool by Pentera. Compare features, ratings, integrations, and community reviews side by side to find the best threat simulation fit for your security stack.
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 that need to validate whether their endpoint defenses actually stop ransomware,not just detect it,should run Pentera RansomwareReady. The platform emulates real attack chains from LockBit, Conti, and REvil using file duplicates so you test safely, then maps findings directly to MITRE ATT&CK and lateral movement paths your SOC actually needs to hunt. Skip this if your priority is recovery planning or you're still building basic detection; RansomwareReady assumes you have EDR deployed and want proof it works against current variants.
