Hi Sheena - Thank you for responding. I don't believe our IT Team is interested in Creative Cloud Packager so.......are you saying that the Site/Port information on that document is what is needed if I have 10 Creative Cloud users at our company need to access. the Adobe Creative Cloud servers? That if those Site/Port information is "white listed" - we should be OK? Also, my IS team is specifically asked for IP addresses.....is the Site/Port information the same thing? (Sorry, again, not a technical individual.)
I know we also have this document too which might help
and this one, both are pretty extensive and probably overlap with each other and the one Sheena provided
If you provide these to your IT department they should have what they need.
