That is exactly what we are seeing. We currently have Carbon Black App Control (Former CB Protection) which adds roughly 25 seconds to our logon. Had multiple tickets opened with Support and they said that this is the best that they can do. However now we are also adding CB Defense (CB Cloud) and it just doubles our logon times to roughly 120 seconds as well. I have multiple tickets opened with CB/Vmware and so far there is no solution . I have an exclusion for FLX*.tmp in complete bypass mode and it just doesn't seem to work. Applying user Policy in logon log skyrockets to 40-60 seconds and we don't even use UEM very heavily as we are using Writable VOlumes Profile only to persist settings
Our normal logon times for average user with 1 appstack and writable:
No security product: 15-22 seconds
Added CBP only - 45-55 seconds
Added CBP and CBC - 120 +
