AgileBlue Cerulean Agent is a commercial extended detection and response tool by AgileBlue. Cisco XDR is a commercial extended detection and response tool by Cisco. 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, integrations, company size fit, 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 security teams with fragmented detection across network, endpoint, and email will see the fastest ROI from Cisco XDR, since its multi-domain correlation actually connects alerts that your existing point tools miss. The platform covers DE.CM and DE.AE strongly, meaning detection is genuinely its strength; RS.MI (containment and recovery) is present but less mature than what you get from pure endpoint-focused vendors. Skip this if your team is still optimizing a single-vendor stack like Palo Alto or CrowdStrike; XDR's real value emerges only when you're already drowning in disconnected alerts.
