Features, pricing, ratings, and pros & cons — compared head-to-head.
Cohesity FortKnox is a commercial backup as a service tool by Cohesity. Commvault HyperScale Flex 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.
Based 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.
Enterprise and mid-market teams protecting multi-petabyte datasets will get the most from Commvault HyperScale Flex because its disaggregated architecture lets you scale compute and storage independently, cutting the waste of traditional monolithic backup appliances. Multi-layered immutability across software, OS, and file system stops ransomware from corrupting backups at any layer, and the anomaly detection engine catches attacks before they spread to recovery points. Skip this if your organization needs tight integration with a single vendor's entire security stack; HyperScale Flex prioritizes recovery resilience and detection over broader incident response orchestration.
