Rubrik hosts NAS backups in isolated, immutable vaults

Organizations increasingly face ransomware attacks that specifically target backup systems to eliminate recovery options, making isolated and immutable backup storage a critical defense layer. Rubrik's Rubrik-Hosted Protection for On-Premise Unstructured Data addresses this by moving NAS backups into vendor-managed, air-gapped vaults that attackers cannot reach or corrupt even if the primary environment is compromised. The inclusion of ransomware detection and sensitive data discovery further strengthens the recovery posture by ensuring organizations know what they have and whether it has been tampered with. This matters because a backup that an attacker can encrypt or delete is no backup at all — resilience depends on backups being both recoverable and trustworthy. Without immutability and isolation, even well-designed backup schedules can be rendered useless by a single ransomware event.
