CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Critical Path Security Léargas Platform
Mid-market and enterprise security teams that need full protocol visibility without sacrificing deployment flexibility should evaluate Léargas Platform; its Zeek foundation delivers deterministic network traffic analysis across physical, virtual, and cloud footprints, and the native support for Splunk, AWS, GCP, and infrastructure-as-code tools means it integrates into existing stacks without forcing rip-and-replace decisions. The platform prioritizes detection and continuous monitoring over response automation, which aligns well with organizations that have mature SIEM investments and want to strengthen their network layer rather than consolidate everything into a single vendor. Skip this if you need managed services or a vendor that handles tuning and threat hunting for you; a twelve-person vendor running open-source Zeek means you're responsible for keeping detection rules sharp.
