AgileBlue Cerulean Agent vs Cybereason XDR: Side-by-Side Comparison (2026)

AgileBlue Cerulean Agent

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.

Cybereason XDR

Mid-market and enterprise security teams dealing with fragmented detection stacks should pick Cybereason XDR for its attack story correlation; it ingests 65+ data sources and collapses alert noise into narratives that actually tell you what happened. The MalOp framework covers NIST DE.CM and DE.AE strongly, meaning detection and analysis are where this platform excels. Smaller organizations or teams without dedicated incident response capacity will struggle with the manual investigation workflows that correlate these stories; Cybereason's managed XDR service exists partly because the self-service model assumes you have people to act on what it finds.
