Vanguard blocks drivers with known security vulnerabilities (usually privilege escalation via arbitrary memory writes) that allow cheat developers to load their cheats into the kernel without approval from Microsoft.
It's hard to know which hardware software monitoring tools will be blocked because many of them repackage other company's drivers. We don't block software packages specifically only the drivers they distribute.
If software that you use is blocked please check with the vendor to see if an update is available and if no update is available please contact them and ask them to fix their vulnerable drivers.
