Cohesity FortKnox vs Commvault Cloud Unity: Side-by-Side Comparison (2026)

Cohesity FortKnox

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.

Commvault Cloud Unity

Enterprise and mid-market teams managing hybrid cloud infrastructure should evaluate Commvault Cloud Unity primarily for its identity system backup and cyber recovery capabilities, which address the gap most backup vendors ignore. The platform covers all six critical NIST CSF 2.0 functions from asset management through incident recovery, with particular strength in the RC.RP recovery execution domain where ransomware playbooks and real-time restoration matter most. Skip this if your priority is detection over recovery, or if you need native cloud-only simplicity without inheriting Commvault's on-premises operational complexity.
