Immutable / WORM Storage
Immutable and WORM (Write Once Read Many) storage prevents data from being modified or deleted for a defined retention period. It is a regulatory requirement in sectors like finance, healthcare, and legal where audit trails must be tamper-proof. Providers differ in how they enforce immutability — some offer software-level locks, others provide hardware-enforced write protection.
