True or False: For the ProxySG to decrypt SSL traffic, the traffic needs to be intercepted by a proxy service?

The statement is true because, for the ProxySG to decrypt SSL (Secure Sockets Layer) traffic, the traffic must indeed be intercepted by a proxy service. When the proxy service acts as an intermediary between the client and the server, it establishes separate SSL/TLS connections with both parties. This interception allows the ProxySG to decrypt the incoming SSL traffic, analyze it for security threats or compliance, and then re-encrypt it before passing it along to the intended destination.

This process is essential for gaining visibility into encrypted traffic, which is increasingly being used for a variety of online communications. Without interception by a proxy service, the ProxySG would not have the capability to access the data carried within encrypted sessions, thus hindering security measures such as filtering and malware detection.

The other options suggest that scenarios exist where interception isn't required or could be conditional, but in practice, for effective SSL decryption by a ProxySG, interception is indeed necessary.
