CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Invary Runtime Integrity Solution
Mid-market and enterprise security teams protecting high-value infrastructure against kernel-level attacks and supply-chain compromises should prioritize Invary Runtime Integrity Solution. It's the only EDR using NSA-licensed kernel verification to catch rootkits, BYOVD exploits, and eBPF malware that standard behavioral detection misses, and it works in air-gapped and embedded environments where most competitors fail. Skip this if your team needs broad endpoint visibility across applications and user behavior; Invary is deliberately narrow, optimized for kernel integrity rather than NIST Detect coverage.
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.
