event-generator vs Filigran OpenAEV: Side-by-Side Comparison (2026)
Features, pricing, ratings, and pros & cons — compared head-to-head.
event-generator 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:
Runtime security teams validating Falco rulesets should use event-generator because it eliminates the friction of manually crafting suspicious behaviors to test detection logic. The tool generates realistic suspect actions that map directly to Falco rules, cutting the typical validation cycle from hours to minutes. It's free and lightweight enough to run in CI/CD pipelines, making it practical for teams without dedicated security testing infrastructure. Skip this if you're already using a commercial threat simulation platform or if your detection stack doesn't center on Falco; the tool's value collapses outside that specific use case.
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.
