How It Works

Proxy-Aware Clients

For proxy-aware clients – e.g. –employees with managed devices, where an internet proxy can be configured – our Secure Web Gateway provides extensive functionality.

Non-Proxy-Aware Clients

For non-proxy-aware clients, e.g. –guests, legacy machines, and servers or IoT – which are essentially users with unmanaged devices where nothing can be configured – our DNS Filter provides web security capabilities. Our DNS Filter does URL filtering for web policy enforcement and includes web threat protection.
