All of the Windows endpoints in the environment are defended by Symantec Endpoint Protection (SEP) clients. Can the UNIX servers (Solaris, HP-UX, AIX, and similar operating systems) also be protected by SEP 12.1 or SEP 14?
Symantec Endpoint Protection and Symantec Endpoint Protection for Linux (SEPFL)
At present, managed and self-managed (unmanaged) Symantec Endpoint Protection clients can be installed on Windows, Macintosh and Linux computers. Managed clients can be viewed and configured from the Symantec Endpoint Protection Manager (SEPM) console. Full system requirements for SEP can be found in Release Notes and System Requirements for all versions of Symantec Endpoint Protection and Symantec Network Access Control
Symantec Data Center Security
While neither SEP nor SEPFL can be installed on HP-UX, AIX or similar, there is an alternate Symantec product which can provide protection: Symantec Data Center Security: Server & Server Advanced.
DCS has its own Management Server which runs on Windows. Events from the servers protected by DCS communicate with this console rather than the SEPM.
