MongoDB has announced that its Client-Side Field Level Encryption (CSFLE) feature, which allows developers to selectively encrypt and decrypt individual document fields in MongoDB databases before data is sent to the database, is now Generally Available (GA). The feature, which was introduced in MongoDB 4.2, enables applications to protect sensitive data without impacting performance, making it a game-changer for businesses that handle highly sensitive medical or prescription data. With CSFLE, developers can encrypt individual fields and documents with all key management, encryption, and decryption operations occurring exclusively outside the database server, providing greater separation of duties and addressing regulatory obligations such as the "right to be forgotten" provisions in new privacy regulations like GDPR. The feature is available on MongoDB 4.2, whether running Atlas or Enterprise Advanced, and can be used with various programming languages and platforms.
