Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise security teams managing hybrid infrastructure will get the most from AgileBlue Cerulean Agent because its behavioral analytics catch threats that signature-based detection misses, and the lightweight agent actually deploys without grinding endpoints to a halt. The tool covers four NIST CSF 2.0 functions across detection and incident response, with particular strength in continuous monitoring and threat analysis. Skip this if your team needs deep forensic replay or extensive third-party integrations; Cerulean Agent prioritizes real-time detection over post-incident investigation depth.
Mid-market and enterprise teams drowning in security alerts will find value in Sekoia Defend's threat intelligence integration, which contextualizes detections instead of just surfacing them raw. The platform covers the full incident lifecycle from continuous monitoring through investigation, with particular strength in NIST DE.CM and DE.AE functions that actually reduce false positives at scale. Skip this if you need mature SOAR automation or recovery playbooks; Sekoia Defend prioritizes detection and triage over orchestrated response, leaving response execution to your existing tooling.
