Features, pricing, ratings, and pros & cons — compared head-to-head.
EDR Healthcheck is a commercial threat simulation tool by Horizon3.ai. Keepnet Labs Email Threat Simulator is a commercial threat simulation tool by Keepnet Labs. 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:
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.
Keepnet Labs Email Threat Simulator
Mid-market and enterprise security teams drowning in phishing and ransomware variants will find real value in Keepnet Labs Email Threat Simulator because it tests your actual email gateway against live attack patterns instead of running disconnected tabletop exercises. The tool's continuous scanning with new attack vectors and automated reporting on email misconfigurations (Open Relay, DNSBL failures) directly feeds ID.RA and DE.CM compliance work, and native Office 365 and Google Workspace hooks mean minimal integration friction. Skip this if your organization hasn't yet standardized on a single email platform or if you need post-breach forensics; Keepnet is explicitly built for the prevention testing loop, not incident response.
