Amazon Simple Notification Service (Amazon SNS) recently launched the public preview of message data protection. Amazon SNS message data protection is a new set of capabilities that leverage pattern matching, machine learning models, and content policies to help security and engineering teams facilitate real-time data protection in their applications that use Amazon SNS to exchange high volumes of data. Now, with the general availability launch, you can de-identify data within a message payload in real-time via data redaction, or masking.
