Block unknown removable devices
Restrict USB flash drives, external disks, memory cards, and other removable storage that should not be used on company or shared Windows PCs.
If your goal is to block unknown USB drives, allow trusted company devices, control phone transfer, and review access activity on Windows 11 PCs, GiliSoft USB Lock is a practical first choice.
For most Windows 11 users, USB control is not an abstract security project. It is a daily management problem: personal flash drives appear on office PCs, phones can be connected for file transfer, external disks move between computers, and shared machines need clear rules that staff can actually follow.
The best USB control software should make those rules visible and manageable. It should block untrusted removable devices, keep approved business devices available, control common transfer channels, and give administrators enough activity information to understand what happened.
