Amazon GuardDuty Tester is a free threat simulation tool. Filigran OpenAEV is a commercial threat simulation tool by Filigran. 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:
AWS security teams evaluating GuardDuty need to validate that its detections actually fire in their environment before incidents do; Amazon GuardDuty Tester cuts through sandbox testing by injecting real proof-of-concept findings directly into your account at no cost. The 408 GitHub stars reflect its adoption among teams that discovered their GuardDuty tuning was silencing critical alerts. Skip this if you're not running GuardDuty yet or if your detection validation workflow already includes threat simulation tools; this is purely about understanding what GuardDuty sees and what it misses in your specific setup.
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.
