Configurations to Watch Out For

The following network/host configurations could cause host isolation to fail:

• • Huntress does not recommend isolating a host with multiple host isolation solutions at the same time. Unforeseen connectivity issues may arise. (i.e isolating with Sentinel One AND Huntress)
  • Computers that require VPN connectivity for internet access (always-on VPNs).
  • Computers that must connect out through a proxy server. In general Huntress does not work with proxies. See more info here!
  • DNS will continue to work even if a host is isolated, but DNS resolution is required in order to isolate and unisolate.
  • If there is any configuration is blocking 1.1.1.1:53/tcp our backup DNS will fail.

Note: If the host has non-default local group policy firewall settings (not global) set, they will be wiped when releasing the host from isolation.
