Ahsay Backup Microsoft Azure vs Cohesity FortKnox: Side-by-Side Comparison (2026)

Ahsay Backup Microsoft Azure

Mid-market and enterprise teams backing up Azure workloads will benefit most from Ahsay Backup Microsoft Azure because it lets you retain encryption keys and control backup location rather than surrendering both to Microsoft, which matters when compliance or data sovereignty are non-negotiable. The tool implements the 3-2-1 rule with immutable snapshots and AES-256 encryption across Azure, S3, and Wasabi, giving you genuine air-gapped copies outside your primary environment. Skip this if your team lacks the operational bandwidth to manage a separate backup appliance; Ahsay requires more hands-on administration than native Azure backup, and that overhead only pays off when you're protecting critical workloads that justify the control premium.

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.
