Compare features, ratings, integrations, and community reviews side by side to find the best endpoint detection and response 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:
Security teams managing osquery at scale will find Doorman's lightweight approach to fleet management valuable when your infrastructure is already built on osquery and you need remote configuration control without the overhead of a commercial EDR platform. The free pricing and 620 GitHub stars reflect active use in lean security shops running osquery across hundreds of nodes. Skip this if you need behavioral threat detection or response automation; Doorman is query management only, not endpoint detection, so it pairs with osquery's detection capabilities rather than replacing them.
