# Build secure access policies

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/learning-paths/replace-vpn/build-policies/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

With Cloudflare Zero Trust, you can apply granular security policies to all traffic proxied from the user device to your private network. Policies can key off of domain name, user identity, device posture, SNI, IP address, port, protocol, and other attributes. Building simple, well-structured policies is an important factor in having a secure organization with a manageable workflow.

## Objectives

By the end of this module, you will be able to:

* Create Zero Trust policies to secure access to your private network.
* Enforce Cloudflare One Client session timeouts.
* Display custom block messages.
* Discover Shadow IT within your private network.
