Common network policies

The following policies are commonly used to secure network traffic.

​​ Block applications

Block content categories which go against your organization’s acceptable use policy.


​​ Check user identity

Configure access on a per user or group basis by adding identity-based conditions to your policies.

User Group NamesinContractors

​​ Enforce device posture

Require devices to have certain software installed or other configuration attributes. For instructions on enabling a device posture check, refer to the device posture section.

In the following example, users can only access an application if they connect from a company device.

​​ Enforce session duration

Require users to re-authenticate after a certain amount of time has elapsed.

​​ Restrict access to private networks

Restrict access to resources which you have connected through Cloudflare Tunnel.

The following example consists of two policies: the first allows specific users to reach your application, and the second blocks all other traffic. Make sure that the Allow policy has higher priority (by positioning it towards the top of the list in the UI).
