Arcserve Cyber Resilient Storage vs Cohesity FortKnox: 2026 Comparison

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.
