Cisco Umbrella (Part of Cisco Secure Client)
Cisco Umbrella is used across the entire campus to block access to malicious sites. Cisco Umbrella roaming client is software used on the Windows and Apple platform to extend web-filtering protection of Cisco Umbrella to mobile clients as they are used off-campus.
How Cisco Umbrella Protects Campus Users
Note about Cisco Umbrella icon presence in users' Docks:
Users on a Mac running a macOS older than macOS 13, or users who received an update to Umbrella while logged in to an active session, may see an icon for Cisco Secure Client in their Docks. Cisco Secure Client is the app by which Cisco Umbrella is enabled.
If you click on the icon, you should get a window like the one below saying that Umbrella is active.
Quitting the Cisco Secure Client apps will not disable Umbrella protection.
The mechanism by which Cisco accomplishes auto-enabling Umbrella changed with macOS 13 and newer, and then changed again with the release of version 5.1.6.103 of Cisco Secure Client. The user experience is very inconsistent and may possibly change again with the next Cisco Secure Client update. Endpoint Administration tests every release of Secure Client before distributing it to campus to ensure that Umbrella is indeed active and protecting the device, even if the app icon never shows in the users' Docks.
