The Decrypt for Application Detection feature within the WSA Decryption options enhances the ability of AsyncOS to detect HTTPS applications. The HTTPS Proxy can decrypt HTTPS connections to web applications. This allows the Application Visibility and Control (AVC) engine to more accurately detect and block web applications that use HTTPS. This feature can help improve the security and performance of the network by identifying and controlling the usage of web applications that may consume bandwidth, pose security risks, or violate compliance policies.
