Azure Blob Storage Encryption
Azure Blob Storage Encryption is a security feature within Microsoft Azure that automatically encrypts data at rest in Azure Blob Storage, protecting it from unauthorized access. It uses industry-standard encryption algorithms like AES-256 to secure blob data, including block blobs, append blobs, and page blobs. This encryption is enabled by default for all storage accounts, ensuring data is encrypted both when stored and during replication across Azure data centers.
Developers should use Azure Blob Storage Encryption when building cloud applications that handle sensitive or regulated data, such as financial records, healthcare information, or personal identifiers, to meet compliance requirements like GDPR, HIPAA, or PCI DSS. It is essential for scenarios involving data storage in Azure, such as backup solutions, media files, or logs, as it provides a seamless, no-code security layer without impacting performance or requiring manual encryption setup.
