Session Control

CA403-GuestUsers-IdentityProtection-AllApps-AnyPlatform-PersistentBrowser

Non-persistent browser session

About this policy

The CA403-GuestUsers-IdentityProtection-AllApps-AnyPlatform-PersistentBrowser policy prevents external users from keeping persistent browser sessions in your tenant. Whatever device a guest signs in from, once the browser closes the session is gone, and the next visit needs a fresh sign-in. You cannot manage a guest device or vouch for who else uses it, so refusing long lived browser sessions is a sensible default. It covers all cloud apps and every external user type, from B2B guests to service providers.

Policy conditions

Users: Specific users
Apps: All cloud apps
