Features, pricing, ratings, and pros and cons, compared head to head.
AgileBlue Cerulean Agent is a commercial extended detection and response tool by AgileBlue. Cohesity FortKnox is a commercial backup as a service tool by Cohesity. Compare features, ratings, integrations, and community reviews side by side to find the best extended detection and response fit for your security stack. Independent and vendor-neutral: our scores and rankings are earned, never bought — sponsored placement is always labeled.
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 facing ransomware threats need FortKnox because its air-gapped virtual vault makes encrypted backups genuinely unreachable during active attacks, not just theoretically so. The immutable snapshots with retention locks address NIST PR.DS and RC.RP functions that most backup tools treat as afterthoughts, while integrated threat scanning before restore prevents you from recovering compromised data. Skip this if your organization can tolerate a longer recovery window; the isolation model trades some restore speed for the certainty that your backup tier stays isolated even when production infrastructure is already encrypted.
Based on our analysis of core features, integrations, company size fit, deployment model, here is our conclusion:
