HarfangLab Cybersecurity Solutions
Mid-market teams managing mixed Windows and Linux infrastructure will get real value from HarfangLab Cybersecurity Solutions because its Rust-based agent actually consumes half the resources of typical EDR platforms while maintaining detection parity. The vendor's focus on NIST DE.CM and RS.AN means you get continuous monitoring and solid forensics support, though incident response automation lags behind competitors like CrowdStrike. Skip this if you need air-gapped deployment as your primary use case; the platform supports it, but it's not where the product matured first.
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.
