Policy Object: Quarantine Device Lists (Strata Cloud Manager)
Configure the quarantine list feature for Strata Cloud Manager Managed Prisma Access mobile user (GlobalProtect) deployments.
Prisma Access allows you to identify and quarantine compromised
devices with the GlobalProtect app. You can either manually or automatically
(based on auto-tags) add devices to a quarantine list. You can block
quarantined devices from accessing the network or restrict the device
traffic based on a security rule.
To get started, set up a
Quarantined Device List. Then use the list as part of identity redistribution.
- Set Up a Quarantined Device List
- Configure Identity Redistribution
- Use Quarantine Device List for Security Policy Enforcement
- Block Login for Quarantined Devices

these steps to add a device to the Quarantined Device List:
- Select .The Shared configuration scope is already selected for you. Leave this option as is.
- Select Add Device.
- Fill in the Host ID and Serial Number fields.
- Select Save.
- Repeat steps 1-4 to add additional devices.
Configure Identity Redistribution
The Identity Redistribution screen is where
you configure how identity information is redistributed in the Prisma Access Infrastructure. Configure identity redistribution to use
the quarantined device list so that all devices on the network that
enforce policy know to block the compromised devices.
Follow
these steps to configure identity redistribution to use the Quarantined Device
List you created:
- Select .
- Select the appropriate configuration scope, Shared or Mobile Users.You can ignore Service Connections for now because Service connections learn from mobile users, remote networks, or external redistribution agents, as shown in the diagram. If you’re unsure about which to select, see Global and Local Policy. Shared is selected by default.

- Select from the sidebar.
- Scroll down to Security Rules and select Add Rule.The Add Security Policy Rule screen appears.
- Scroll down to DEVICES under either Source or Destination and select Match Quarantined Devices.
This tells your rule to use devices in the quarantine list as the match criteria, whether you specify Quarantine as the Source Device for Source traffic or the Destination Device for Destination traffic.
- Under Action and Advanced Inspection, specify an action that blocks the quarantined device, such as Deny as required by your rule.
- Select Save.
