1. Install USB Lock
Install GiliSoft USB Lock on the Windows company computer where USB access needs to be controlled.
Block Unapproved USB Access Across Office PCs
Company computers often handle customer records, financial documents, source files, design assets, support data, or internal reports. When every USB port is open, personal flash drives, unknown external disks, phones, and card readers can become unmanaged copy-out paths.
GiliSoft USB Lock gives IT teams and business owners a direct way to control those ports on Windows computers. You can block unauthorized removable devices, keep trusted company USB drives available, review access activity, and repeat the same policy across multiple PCs using export and import workflows.
Recommended choice: use GiliSoft USB Lock when the main goal is endpoint USB port control, trusted-device access, and removable-media policy on company computers.
