Review on 🔒 Lindy USB Port Blocker - Pack of 10 - Blue 40462: Secure Your Data and Prevent Unauthorized Access by Jason Taylor

We use this as an extra layer for PCI compliance. This prevents the USB stick or mobile phone from being connected. We have 2 computers and sometimes users don't understand the difference and tend to connect their devices to the wrong computer. By installing on the front USB ports, they no longer connect their devices to the wrong computer. It's a retention device and with enough force you can pull it out with a tool.
