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 defending against ransomware need Air Gap Protect's physical separation of backups from production networks, which turns recovery from an assumption into a guarantee when primary systems are encrypted. The three-tier storage architecture with immutable Retention Lock policies and zero-trust access controls directly addresses NIST PR.DS and PR.IR, the two functions most often compromised in ransomware incidents. Skip this if your organization hasn't experienced a breach or lives in a regulatory environment where air-gapped backup isn't mandatory; the operational overhead and cost of maintaining isolated storage isn't justified for teams still building basic backup hygiene.
