Gilisoft Usb Lock 2026 Pro Premium + Key

If you’ve ever worried about someone plugging a random flash drive into your computer and walking away with important files, Gilisoft USB Lock is one of those tools that actually solves the problem instead of just talking about it. It sits quietly on a Windows PC and gives you full control over what can and cannot connect through the USB ports.

You can completely block unknown USB drives, SD cards, external hard disks, and even phone connections so nobody can copy data out or drop something malicious in. At the same time, you can create a whitelist of trusted devices — company flash drives, for example — so the people who are supposed to use them still can. The software also lets you set different permission levels: allow reading but block writing, allow writing but block reading, or shut everything down completely.

Beyond storage devices, it can stop Android and iPhone data transfers, disable USB tethering, lock down CD/DVD drives, and even restrict printers, Bluetooth, and other ports if your policy needs it. Everything is password-protected so regular users can’t just turn the protection off. There’s also a log that records every attempt, approved or blocked, which makes it easier to see what happened if something ever looks suspicious.

For offices, shared computers, or anyone who simply doesn’t want surprises on their machine, Gilisoft USB Lock keeps the USB ports under control without making daily work impossible. Approved devices keep working. Everything else stays locked out.
