Zeek Agent vs Exein Runtime: 2026 Comparison
Zeek Agent is a free endpoint detection and response tool. Exein Runtime is a commercial endpoint detection and response tool by Exein. 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:
Linux and macOS teams running Zeek already have a natural home for Zeek Agent; it pipes endpoint telemetry directly into your existing detection pipeline without requiring a separate platform. The tool captures file, socket, and process events at the kernel level, giving you raw visibility that feeds Zeek's network detection logic rather than forcing you into a separate EDR console. This is not for buyers shopping for a standalone endpoint tool with its own alerting and response capabilities; Zeek Agent is a collector, not an analyst, and you'll need Zeek expertise to turn events into actionable rules.
SMB and mid-market teams protecting IoT fleets will get immediate value from Exein Runtime's firmware-embedded detection, which catches threats at the kernel level before they reach your network. The eBPF-based monitoring and AI-powered anomaly detection address the NIST DE.CM and DE.AE functions that most IoT stacks leave blind, giving you actual visibility into device behavior instead of guessing. This is not for buyers who need cross-platform endpoint coverage across servers, desktops, and mobile; Exein is IoT-specific, and that's where its teeth are.
