Cohesity FortKnox vs Elastio Cloud Coverage: 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.

Elastio Cloud Coverage

Mid-market and enterprise teams managing AWS or Azure backups need Elastio Cloud Coverage because it's the only tool that actually validates whether your recovery points are clean before you need them. It covers the full stack,EC2, EBS, S3, FSx on AWS and VMs, Managed Disks, Blob Storage on Azure,and runs continuous monitoring against ransomware and corruption, mapping directly to NIST RC.RP and DE.CM. Skip this if your backups are infrequently tested or if you're still treating backup validation as a manual quarterly checkbox rather than an automated control.
