A vault needs three properties. Storage provides two of them.
Isolation and immutability come from your vault platform. Integrity, proof that a copy was clean when it went in, has to be established before the lock. Once a copy is locked, whatever it carries stays for the full retention period.
01Isolation
The vault sits in its own account or tenancy, behind its own identity boundary. Credentials stolen from production do not reach it.
02Immutability
A retention lock keeps each copy from being altered or deleted until its retention period ends. It protects the copy exactly as it was written.
03Integrity
Each copy is proven free of the attack before it is locked. This is the property Elastio provides: Pursuit analyzes the system copy for an active attack, and Hunt hunts the data for ransomware.
Isolation and immutability decide whether the copy survives an attack. Integrity decides whether restoring it ends the attack or starts it again.
