Restrict legacy remote management tools via web filtering

Actions taken

Enabled DNS-level web filtering to block known remote monitoring and remote support services previously used to access this environment (including prior vendor’s RMM and remote desktop tools). This prevents any future remote connections through those platforms while leaving standard business web access intact.
Implemented the change centrally at the network level so that protected devices can no longer reach those remote access services, even if old software or agents remain installed.
Verified that business-critical and customer-facing services continue to function normally after applying the new filtering policies.

Improved security by eliminating an unused remote access path from the previous IT provider.
No change to day-to-day internet browsing or access to approved business applications is expected.

Devices that go off network (out of the office) are still remotely accessible by previous IT tools and staff. This will be resolved by re-imaging or replacing those devices via the PC refresh activity starting soon.
