What is the role of a ProxySG when configured as an SSL server?

The role of a ProxySG configured as an SSL server primarily revolves around receiving and processing client requests. In this setup, the ProxySG acts as an intermediary that establishes an SSL connection with the client, allowing it to handle encrypted traffic. When a client makes a request, the ProxySG decrypts the SSL/TLS traffic to inspect it, applying security policies, filtering, and potentially caching the response before forwarding it to the appropriate content server.

This process enhances security and performance. By terminating the SSL connection at the ProxySG, organizations can effectively inspect for malware or policy violations, which is critical in maintaining network security. Additionally, the ProxySG can then create a new secure connection to the content server, ensuring that the entire transaction remains secure.

This role is essential for enabling visibility and control over web traffic, which might be compromised if a device merely acted as a pass-through without processing client requests. Therefore, the main function of receiving and processing those requests distinguishes the ProxySG's role in this context as pivotal in secure web traffic management.
