Amazon SNS message data protection is a 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, you can de-identify outbound message data within a payload, in real-time, via data redaction or masking. Thus, each endpoint subscribed to your Amazon SNS topic may receive a different payload from the topic, with different sensitive data de-identified, according to their data access permissions.
