Our campus has a network access control (NAC) solution on campus - Aruba ClearPass OnGuard! OnGuard is a tool that allows SCU to ensure computers on our networks are configured to securely access them and better protect users from malicious activity. OnGuard checks to make sure you have anti-virus software installed like SentinelOne, your computer's firewall is turned on, and check that system updates are enabled.
Note: Systems connected to eduroam that do not have OnGuard installed, or are not compliant with OnGuard's policy will not have access to campus resources that we need to protect. Most significant of these is the MySCU Portal! So please refer to the instructions below to help you get your systems started with OnGuard.
The OnGuard installer is available for Windows, macOS, and Linux on-campus only at the OnGuard download page: https://www.scu.edu/onguard
