Microsoft Azure launches tamper-proof Azure Immutable Blob Storage for financial services

Community Manager

I’m pleased to announce that Azure Immutable Blob Storage is now in public preview – enabling financial institutions to store and retain data in a non-erasable and non-rewritable format – and at no additional cost. Azure Immutable Blob Storage meets the relevant storage requirements of three key financial industry regulations: the CFTC Rule 1.31(c)-(d), FINRA Rule 4511, and SEC Rule 17a-4. Financial services customers, representing one of the most heavily regulated industries in the world, are subject to complex requirements like the retention of financial transactions and related communication in a non-erasable and non-modifiable state. These strict requirements help to provide effective legal and forensic surveillance of market conduct.


Software providers and partners can now rely on Azure as a one-stop shop cloud solution for records retention and immutable storage with sensitive workloads. Financial institutions can now easily build their own applications taking advantage of these features while remaining compliant. These Write Once Read Many (WORM) policies apply to all tiers of storage (hot, cool, and archive). This industry leading compliance storage offering is now available at no additional cost on top of the base pricing of Azure storage!
