Arcserve Cloud Cyber Resilient Storage
Mid-market and enterprise teams that treat ransomware recovery as a business continuity problem, not just a backup problem, should evaluate Arcserve Cloud Cyber Resilient Storage. The platform maps directly to NIST RC.RP (Incident Recovery Plan Execution) and PR.IR (Technology Infrastructure Resilience), meaning it's architected around restoration speed and immutability rather than just data storage. Skip this if your priority is real-time threat detection or preventing the initial compromise; Arcserve assumes the attack succeeds and focuses on how fast you can get operational again.
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.
