Cohesity FortKnox is a commercial backup as a service tool by Cohesity. Commvault Distributed Storage is a commercial backup as a service tool by Commvault. Compare features, ratings, integrations, and community reviews side by side to find the best backup as a service fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Mid-market and enterprise teams needing distributed backup storage with tight integration into existing Commvault infrastructure should evaluate Commvault Distributed Storage, particularly if your recovery time objectives depend on on-premises resilience. The platform addresses RC.RP recovery execution directly through its distributed architecture, reducing single points of failure in backup restoration workflows. Note the end-of-availability announcement with 2026 EOL, which means this is best suited for organizations with near-term recovery needs rather than those building a five-year backup strategy; if you're making a multi-year backup infrastructure investment, the vendor's roadmap uncertainty makes this a risky foundation.
