Doorman vs Zeek Analysis Tools (ZAT): Side-by-Side Comparison (2026)
Features, pricing, ratings, and pros & cons — compared head-to-head.
Doorman is a free threat hunting tool. Zeek Analysis Tools (ZAT) is a free threat hunting tool. Compare features, ratings, integrations, and community reviews side by side to find the best threat hunting fit for your security stack.
CST VerdictBased on our analysis of available product data, 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.
Incident response teams already collecting Zeek network logs will extract real value from ZAT's Python-native ML pipeline; you get forensic analysis speed without building custom pandas and scikit-learn workflows from scratch. The 451 GitHub stars and active maintenance signal a tool that teams actually use post-breach, not one gathering dust. Skip this if you need a point-and-click UI or support for non-Zeek data sources; ZAT demands Python fluency and assumes your team is comfortable operationalizing machine learning models in incident workflows.
