Endpoint Protection

Is this for SEP 11.x or 12.1?

Here is one solution for 11.x:

How to check which SEP client is not using the GUP to download content

You can enable sylink logging as well:

How to confirm if SEP Clients are receiving LiveUpdate content from Group Update Providers (GUPs)

You can also check the log on the client. View Logs >> Client Management >> View Logs >> System Log

Open the SEP client

View Logs and in System logs check for GUP Proxy here it will give the IP address of the GUP configured
