CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Enterprise security teams investigating advanced breaches need NikOS Everest for its packet-level forensics depth; most tools give you alerts, this one gives you the actual network conversation that proves what happened. Query response time improved 4X in version 5.1, and the platform maps cleanly to NIST DE.CM and DE.AE for detection and analysis, though it prioritizes forensic investigation over automated response actions. Mid-market buyers should verify their network capture and storage budget before committing; this is a specialist tool for organizations with the ops maturity to run on-premises packet infrastructure, not a replacement for broader network monitoring.
Network engineers and incident responders who need to validate what's actually crossing the wire will find tcpdump indispensable; it captures raw packets at the kernel level with zero overhead, making it the fastest way to confirm traffic patterns or isolate malicious flows when your monitoring tools disagree. It ships standard on Linux and BSD, requires no licensing, and integrates directly into NIST Detect workflows because you're looking at unfiltered evidence. Skip this if you need a GUI or automated threat correlation; tcpdump demands command-line fluency and manual packet inspection, which is exactly why practitioners who know what they're doing prefer it.
