Endpoint Protection

I need to block multiple sites, does anyone have a list with several social media sites, games?

Is it possible to import list with multiple sites?

Is it possible to put a blocking message? Company logo

Use the directions in the KB article:

You can create 'Host Groups' list and add domains that you need to block. There are manual steps needed but you can add large groups of domains in one shot..see here:

You can add a custom notification:

No options for adding a logo though.

Cool would be exactly what I need, but it's pretty hard work.
