How it works

To protect your network against threats arising from the web, Web Gateway filters the traffic that goes out and comes in.

Following the implemented web security rules, Web Gateway filters the requests that users send to the web from within your network, and the responses that are sent back from the web. Embedded objects sent with requests or responses are also filtered.

As a result of the filtering process, requests, responses, and embedded objects, are blocked or allowed.

The workflow is as follows:

  1. Requests are sent from your network to the web.
  2. Web Gateway filters requests and responses.
  3. Responses are sent from the web to your network.

To perform the filtering process, Web Gateway uses a rule engine and several filter engines or modules, for example, the Anti-Malware module or the URL Filter module. These modules complete particular jobs when the implemented web security rules are processed.

You can configure the web security rules and the behavior of the filter modules to adapt them to the requirements of your organization.

The filtering process also relies on the operating system of Web Gateway, which is MLOS 3 (McAfee Linux Operating System, version 3).
