bro-osquery-module vs Zeek Analysis Tools (ZAT): Side-by-Side Comparison (2026)
Features, pricing, ratings, and pros & cons — compared head-to-head.
bro-osquery-module is a free digital forensics and incident response tool. Zeek Analysis Tools (ZAT) is a free digital forensics and incident response tool. Compare features, ratings, integrations, and community reviews side by side to find the best digital forensics and incident response fit for your security stack.
CST VerdictBased on our analysis of available product data, here is our conclusion:
Incident response teams already running Osquery on Linux endpoints will gain forensic depth by loading Bro IDS logs as queryable tables, turning packet captures into structured threat hunting data without a separate database. The 28 GitHub stars reflect modest but active adoption among teams that have normalized Osquery as their endpoint query engine. Skip this if your infrastructure doesn't already run both Bro and Osquery; the integration tax isn't worth it for teams still standardizing on a single forensic platform.
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.
