AgileBlue Cerulean Agent is a commercial extended detection and response tool by AgileBlue. Darktrace ActiveAI Security Platform is a commercial extended detection and response tool by Darktrace. Compare features, ratings, integrations, and community reviews side by side to find the best extended detection and response fit for your security stack.
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.
Darktrace ActiveAI Security Platform
Mid-market and enterprise security teams with limited SOC capacity should evaluate Darktrace ActiveAI for its autonomous response layer, which containment actions before human review rather than just flagging threats. The platform scores strongly on NIST DE.CM and DE.AE (continuous monitoring and anomaly analysis), reflecting real-time behavioral detection across email, identity, network, and endpoint in a single pane. Skip this if your organization has mature incident response procedures and wants human analysts fully in control of containment decisions; Darktrace's autonomous posture works best when you're understaffed and willing to trade some investigative oversight for speed.
