Tutorial: Configure Cloudflare with Microsoft Entra ID for secure hybrid access

  • Članek

In this tutorial, learn to integrate Microsoft Entra ID with Cloudflare Zero Trust. Build rules based on user identity and group membership. Users authenticate with Microsoft Entra credentials and connect to Zero Trust protected applications.

Prerequisites

Integrate organization identity providers with Cloudflare Access

Cloudflare Zero Trust Access helps enforce default-deny, Zero Trust rules that limit access to corporate applications, private IP spaces, and hostnames. This feature connects users faster and safer than a virtual private network (VPN). Organizations can use multiple identity providers (IdPs), reducing friction when working with partners or contractors.

To add an IdP as a sign-in method, sign in to Cloudflare on the Cloudflare sign in page and Microsoft Entra ID.

The following architecture diagram shows the integration.
