Block USB/SD Drives
Block read or write access to USB drives, SD cards, external disks, and selected non-system partitions unless the device is approved by policy.

Data leakage often starts with unmanaged USB ports, personal flash drives, external disks, and mobile devices connected to office PCs. GiliSoft USB Lock helps control which devices can connect, read data, write data, or open removable-media channels on Windows computers.
Use it to block USB storage, SD cards, CD/DVD media, phone data transfer, USB tethering, printers, Bluetooth, and selected ports while keeping approved devices available through trusted-device whitelist rules. Activity logs also help administrators review denied access, approved access, and policy events after they happen.
Choose USB Lock when the main goal is device control and removable-media policy. If the goal is encrypting the drive itself, compare USB Encryption; if the goal is locking local folders or shared folders, compare File Lock Pro.
Block read or write access to USB drives, SD cards, external disks, and selected non-system partitions unless the device is approved by policy.
Restrict CD, DVD, Blu-ray, and optical-drive channels so removable media cannot become an unmanaged copy path on shared or office PCs.
Restrict phone data transfer over USB so Android and iPhone connections do not quietly become another path for moving files in or out.
Block mobile-device tethering through USB to prevent controlled PCs from using phone hotspot internet access through unmanaged channels.
Create a trusted-device whitelist so approved company USB drives remain available while unknown or personal storage devices stay blocked.
Review USB activity, blocked access attempts, allowed-device history, and whitelist events when administrators need a clearer policy trail.
Block selected websites to reduce unauthorized web access paths. Blocked pages can be redirected to a blank or custom blocked page.
Restrict removable media, card readers, phones, printers, modems, COM/LPT ports, infrared, Bluetooth, and 1394 ports based on endpoint policy.
Block selected programs and system panels when the endpoint needs tighter local control beyond removable-device restrictions.
Protect policy settings with password-based self-protection, invisible mode, failed-password handling, and alert options for suspicious access attempts.
Copy restriction is part of the broader policy workflow, but the core value of USB Lock remains device control, USB port restrictions, and removable-media access enforcement.
Reduce removable-media data leakage by combining device blocking, whitelist rules, copy restrictions, and logs into one practical Windows workflow.
USB Lock helped us enforce removable-media policy on shared office computers without interrupting approved workflows.
Block USB/SD Drives gave us cleaner control over copy-out risks, especially on front-desk and support machines.
CD and media lock controls made policy enforcement clearer for both administrators and non-technical staff.
Restricting Android and iPhone USB data access closed a gap we had in mobile-to-PC transfer control.
USB tethering restrictions helped us prevent unmanaged internet channels on controlled desktop environments.
Trusted device whitelist rules let approved company USB drives work normally while blocking unknown devices.
Activity logs are useful for incident review because we can see exactly when deny and allow events occurred.
USB Lock is for Windows users and teams that need to control removable-device access, trusted USB devices, and USB-based data transfer channels without turning every endpoint into a manual support task.
Reduce unauthorized data transfer from office PCs by blocking unknown USB storage devices and allowing only approved media.
Keep approved company USB drives working while blocking personal or unknown removable devices through whitelist rules.
Control removable media, CD/DVD access, mobile-device connections, and other local device channels on shared desktops and laptops.
Keep public or semi-managed computers usable while preventing students, guests, or temporary users from copying data through removable devices.
Protect high-exposure workstations where sensitive files, customer records, or internal documents should not leave through personal storage devices.
Apply straightforward allow, block, and logging rules without building a full enterprise endpoint-management stack.
USB Lock is a device-control product. It protects the PC side of the workflow: which devices may connect, which removable channels stay blocked, and which access attempts should be logged.
Choose it when the main risk is unauthorized USB drives, phones, external disks, CD/DVD media, or removable-device access on Windows PCs.
Choose USB Encryption when the USB drive itself needs a password-protected secure area for carrying protected files between computers.
Choose File Lock Pro when the main task is hiding, locking, or password protecting local folders, shared folders, or private files.
Choose AI Agent Lock when the concern is scripts, agents, injected input, or machine-driven activity operating the computer.
USB Lock helps when removable-device access should be managed by policy instead of left open to every flash drive, phone, external disk, or media device.
Stop unknown flash drives and external disks from becoming an uncontrolled path for copying files out of business computers.
Keep trusted company drives available while preventing unapproved removable devices from connecting to managed PCs.
Close USB-based mobile data channels and phone hotspot workflows that bypass normal network and endpoint policy.
Apply removable-media controls to front-desk PCs, training-room computers, lab machines, and shared workstations.
Restrict access to optical media, card readers, and selected peripheral channels where removable data movement is a concern.
Use deny and allow logs to understand when device access was attempted, blocked, or approved during normal operation.

Choose the product based on what needs to be controlled: devices, encrypted portable storage, local files, or automated PC operation.
Use USB Lock when the main need is endpoint USB control, device blocking, whitelist policy, and data-leak prevention.
Use USB Encryption when the removable drive should contain a secure encrypted area protected by password.
Use File Lock Pro for folder privacy, password-based access control, hide mode, and shared-folder protection.
