Immutability & Legal Holds: Defending Against Ransomware
Ransomware doesn't just target your production data—it targets your safety net.
Modern attacks are designed to delete or encrypt your backups before striking the production environment. Sendense prevents this by making backups physically untouchable through two core mechanisms: S3 Object Lock and Linux File Immutability.
WORM Storage
Write Once, Read Many. Once data is written to the repository, it cannot be modified or deleted until the retention period expires.
Legal Holds
Override expiration dates instantly. Lock specific backups or entire repositories for litigation or forensic investigation.
Two Layers of Protection
Sendense applies immutability at the source and the destination. On-premises, we utilize the Linux immutable flag to prevent local deletion. In the cloud, we leverage S3 Object Lock in Governance or Compliance modes, ensuring that even if an attacker gains root access, your secondary copies remain safe.
Why Legal Holds?
Retention policies are for normal operations. Legal holds are for crises. Whether it's a pending lawsuit or a suspected breach, you can freeze backups globally or per-VM with a single click, ensuring evidence is preserved indefinitely regardless of policy.
