rThreat is a commercial threat simulation tool by rThreat. EDR Healthcheck is a commercial threat simulation tool by Horizon3.ai. 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, company size fit, deployment model, here is our conclusion:
Security teams who need to validate that their detection stack actually works should use rThreat to simulate both known and zero-day threats against live controls. The platform tests antivirus, firewalls, IDS/IPS, and SIEM in one workflow, directly supporting NIST DE.CM continuous monitoring and DE.AE incident analysis, which means you're not just running tabletop exercises. Skip this if you're looking for a tool that also remediates findings or integrates deeply with your incident response platform; rThreat is built to expose gaps, not close them.
Security teams that doubt their EDR is actually catching attacks should run EDR Healthcheck before your next board meeting; it runs autonomous penetration tests that expose detection gaps your vendor's marketing claims won't reveal. The tool maps directly to NIST DE.CM and DE.AE, meaning you get continuous visibility into which attack techniques slip past your controls and why. Skip this if you're looking for a platform that remediates findings automatically; Healthcheck tells you what's broken, not how to fix it.
