Pertaining to web services, Secure-Adaptive Architecture (SAA) refers to a particular approach towards the security management issues inherent in data transfer over computer networks, relating to certain services, such as micropayments.

In SAA, personal information (such as an end-user's name, banking information, or personal identity numbers such as Social Security numbers) is not retained. This has two main benefits: For the end-user, the chance of identity theft and fraud is considerably reduced. For the service provider, it means that direct communication with the end-user's financial institution is unnecessary.
SAA uses "best in class" proven security techniques to ensure the safe transfer of data through network resources. These include protocols such as SSL communications, client-side authentication and AES encryption.
SAA requires consistent and pervasive, real-time monitoring of network resources to ensure security.
