Create a policy
While Enterprise Threat Protector (ETP) includes a default policy, you can configure a policy to define how your company handles known or suspected threats.
As a best practice, assign Security Connector to the malware and command and control (C&C) categories. A C&C threat indicates that a user’s machine is already compromised by the time it’s detected. To clean compromised machines, you can use Security Connector to identify infected machines and get the information you need for remediation.

In the Proxy Settings area:
- To enable the ETP proxy, toggle Enable Proxy to on.
- To require that ETP Proxy authorizes connections from the on-premises proxy, enable Proxy Authorization. To use this setting, you must configure proxy credentials in ETP and in the on-premises proxy. For more information, see Proxy authorization.
- If you want to allow outbound traffic on a new origin port, in the Origin Ports field, enter the port number or port range. Separate each port number or range with a comma. By default, the full web proxy allows outbound traffic to ports 80 to 84, 443, 4443, 8080, 8443, and 8888.
If you are configuring proxy chaining or the full web proxy, enable
Trust XFF Header. Your organization must be licensed for ETP Advanced Threat.
