I am doing a vulnerability scan for a client that has ~300 endpoints. When I run host alive testing on the workstation asset group, there are only a handful that come back, and only a smaller handful that have successful authentication.
Additionally, when I run a regular vulnerability scan, it runs for hours at a time and then comes back with no hosts alive, which I know is not true.
Whitelists have been put in place on their endpoint protection and firewall, so I'm not entirely sure why the scan is encountering these issues.
I was hoping someone would have some advice/knowledge on some potential reasons this would be happening. Any helps is much appreciated!
