Symantec Endpoint Protection Windows 10 Compatability

Is Symantec Endpoint Protection compatible with Windows 10?

Only if it is the latest Symantec Endpoint Protection version 12.1.6.  Symantec Endpoint Protection 12.1.5 and previous versions are not compatible with Windows 10.

With Microsoft upgrading Windows 7 and Windows 8 to their newest OS platform, Windows 10, businesses are evermore challenged in keeping their security solutions up to date.


We recently upgraded to SEP 12.1.5 and rolled out mostly unmanaged client and a few managed ones. Our organization is now ordering PCs with Winows 10 preinstalled and we need to update Symantec yet again for compatibility. Problem is, our organization does not have proper bandwidth resources to push out the SEP 12.1.6 client to all PCs. On top of that, most of our users are on thin clients. Our newest thin client images for HP t620 already include the SEP 12.1.5 client.

The question is this: Can I update SEPM to 12.1.6 to create the new package for Windows 10 PCs but leave all existing PCs/ thin clients on 12.1.5?  Will the 12.1.5 managed clients still talk to SEPM 12.1.6 and continue to download definitions without the need to update?   As long as the base version is the same (i.e 12.1.x) then SEPM and SEP client can be on different versions


Additionally, posts on the official Symantec forum state that an unmanaged SEP 12.1.6 client can be installed on Windows 10 machines by downloading instead of updating SEPM to 12.1.6 .

Symantec Endpoint Protection (SEP) adds support for Windows 10 with 12.1.6 MP1.

For Symantec Endpoint Protection 12.1, a maintenance patch has been released on July 29, 2015. Customers will need to be current on maintenance to receive the maintenance patch update. For more information, visit our SEP 12.1 Windows 10 Knowledge Base.
