Financial Services organizations regulated by SEC, CFTC, FINRA, IIROC, FCA etc. are required to retain business-related communication in a Write-Once-Read-Many (WORM) or immutable state that makes it non-erasable and non-modifiable for a certain retention interval. The immutable storage requirement is not limited to financial organizations, but also applies to industries such as healthcare, insurance, media, public safety, and legal services.
Today, we are excited to announce the public preview of immutable storage for Azure Storage Blobs to address this requirement. The feature is available in all Azure public regions. Through configurable policies, users can keep Azure Blob storage data in an immutable state where Blobs can be created and read, but not modified or deleted.
For more details on the feature, see the Microsoft Azure Blog.
