Symantec Endpoint Protection

Antivirus and threat protection software

The CIO program is pleased to provide Antivirus software for your home computer at no cost to you. This software is provided to employees and collaborators to enhance the security of the LLNL network by protecting the non-LLNL computers that connect remotely.

Symantec Endpoint Protection (SEP) is the LLNL standard application for Antivirus and Threat Protection on Windows and Mac computers. The CIO recently purchased the rights to provide SEP for home use to LLNL employees and collaborators. The home use version of the software is intended for use on non-LLNL computers only. LLNL provides this software as a benefit to employees but does not provide support other than the Windows end-user guide and Mac end-user guide.

The Symantec Endpoint Protection software is available for download for users with a valid OUN and OTP. For questions regarding this software license please read the home use agreement or contact, Site License Manager / Vendor Liaison, Laura Farro (
