What are the two main client connection methods for the ProxySG?

The two main client connection methods for the ProxySG are explicit proxy and transparent proxy.

An explicit proxy requires client devices to be configured to point to the proxy server, meaning that the proxy is used intentionally by the user or the application. This configuration allows for more control over user traffic and enables features such as authentication, logging, and policy enforcement based on the user's needs. In explicit mode, client applications must be configured to direct their traffic through the proxy, which allows for seamless enforcement of security policies by inspecting and managing web traffic.

On the other hand, a transparent proxy operates without any configuration on the client devices. The proxy intercepts traffic between the client and the internet, making it "transparent" to the user. This is useful for ensuring that all traffic is filtered and logged without requiring any changes to client-side applications. As a result, users do not need to know that their traffic passes through a proxy, enabling widespread deployment without user intervention while still effectively applying policies.

These connection methods serve distinct purposes and are pivotal in implementing a comprehensive web security strategy with ProxySG.
