Microsoft Defender for Endpoint (MDE) for PC | Mac | Linux (offered by ITS)
MDE is the preferred enterprise malware defense tool for the campus and is available for the Windows, Mac and Linux operation systems. The Information Security Office considers MDE to be one of the most effective malware protection tools available and has incorporated MDE telemetry into their automated monitoring capabilities for campus.
Cisco Secure Endpoint (formerly AMP)
Cisco Secure Endpoint was used as the primary malware protection tool for campus for a number of years, but has been replaced with Microsoft Defender for Endpoint (MDE). Campus units that are currently using Cisco Secure Endpoint are advised to migrate to Microsoft Defender for Endpoint as soon as possible as the university's license will continue to shrink and will eventually be retired.
