The Best USB Port Locking Tools

1. ThreatLocker Storage Control – GET DEMO


ThreatLocker Storage Control applies security measures to USB ports and also other storage devices. The system implements a “deny all” strategy. So, all USB ports are blocked. However, they are still responsive, so the port is aware whenever a device is connected – it isn’t completely crippled.

The main features of ThreatLocker Storage Control are:

  • A default block on all USB devices
  • An alert when a device is inserted
  • Notification to the system administrator
  • Options to allow specific devices
  • Activity logging

Some devices can be approved for use. The permission will apply to a specific user, which creates extra security measures. Each USB stick can be identified by its serial number and this ID is used in the access rights management service that is built into the ThreatLocker system.

The permission for a device to attach can be revoked. A USB can also be allocated for use by multiple users and that allocation can be altered. The ThreatLocker system is a cloud platform. System administrators set up security policies in the console, which can be accessed through a Web page. This interface also controls all of the other modules on the ThreatLocker platform.

ThreatLocker also provides protection for files of sensitive data held on servers and it can block all software from running or accessing data stores. You can examine the full ThreatLocker system by accessing a free demo account.


ThreatLocker Storage Control is our top pick for a USB port-locking tool because it implements USB port controls on all of the devices in a corporate fleet from a central console. The system immediately instructs all ports on protected computers to block all USB devices from attaching. This prevents infected devices from transferring viruses onto endpoints and implements data theft blocks. Once the ban is in place, the administrator can authorize specific devices by their serial numbers. These devices can be linked to a user account or permitted to attach to one specific computer. USB ports are not turned off, so the administrator keeps the option of updating instructions.

3. GiliSoft USB Lock

GiliSoft USB Lock

The GiliSoft USB Lock is primarily suited for USB port locking; however, it can detect and block other peripheral devices. So regardless of whether it’s a phone, SD card, or USB, the GiliSoft USB Lock will see its entry and stop it from interacting with your device if it detects a threat.

Main Features

  • Blocks a variety of peripheral devices, such as smartphones, USBs, and SD cards
  • Prevents reading and burning of discs
  • Lets you look at USB activity history

The tool has an alert system to email you if anyone tries to access it and inputs the wrong password. It will also allow you to whitelist specific devices so that you don’t have to trouble yourself with entering the password every time you insert a USB.

Its copy protection feature ensures that nobody will be able to copy your files to an unapproved device. Another excellent feature is its invisible mode, which lets the app run in the background undetected.

The tool also features a robust self-protection mode, which will prevent anyone without sufficient privileges and entering the device’s password. For example, if a wrong password is entered five times, alerts are sent out, and that login session is temporarily banned.

With that being said, the tool does have a bit of a learning curve. Its UI can be a bit confusing for non-technical users. The tool has a month-long free trial and costs $59.99

4. NewSoftwares USB Block

NewSoftwares USB Block

USB Block by NewSoftwares is one of the most lightweight USB port locking tools that will allow you to stop data leaks and block external hardware from interfering with your operations. In addition, the tool can block out all external storage devices from accessing your data and thereby stop interferences.

Main Features

  • Stealth mode hides that you’re even running the tool

  • The tool allows you to check if there has been any illegal activity on your system
  • Great GUI
  • Very lightweight

The tool asks for a password whenever an unauthorized USB device, CD, DVD, or similar storage device accesses your computer. After that, USB Block will stop duplicating your files or copyrighted material to another device without your explicit permission.

The tool also allows you to block network access. For example, you can stop Wi-Fi, Ethernet, Map Network Drives, or other avenues that let malicious actors access the Run command on your device.

The tool takes advantage of a multi-layered patent pending protection that functions on the Windows Kernel level and stops all unauthorized devices from accessing your device even if it’s in Safe Mode. Much like the GiliSoft, it features a stealth mode, and it will erase all shortcuts from your device and hide that you’re even using USB Block.

NewSoftwares records three kinds of hacking attempts: Unauthorized Uninstall, Invalid Password, and Program Deletion attempts. All of these display the username, date, and time of the effort.

You can also set up an authorized list so that your drives are instantly recognized and trusted.

With that being said, the tool lacks some of the power of more complex solutions, and the price is a bit steep at $49.95. However, there’s also a limited-functionality version you can use to test it out.

5. EndPoint Protector Device Control

EndPoint Protector Device Control

EndPoint Protector Device Control is an award-winning, endpoint-centric DLP(Data Loss Prevention) tool. Although it isn’t just a port locking tool, we felt it deserved a spot on this list. In addition, the tool has cross-platform support, supporting macOS, Linux, Windows devices, and Thin Clients.

6. Systools USB Blocker

Systools USB Blocker

The SysTools USB Blocker allows you to block and unblock USB ports on your devices easily. The UI is relatively simple and easy to learn, even if you aren’t technically inclined. This is an excellent tool if you’re looking for a tool that combines an easy-to-learn experience with very few more advanced features to confuse you.

Main Features

  • Supports all Windows installations
  • Extremely easy to use and user-friendly
  • Prevents file copying and tampering
  • Blocks most external devices
  • You can lock ports of multiple devices at once

It will block various external devices, including Flash drives, pen drives, external HDDs, etc. It also allows you to set up a schedule for when you want your ports locked/unlocked.

To lock or unlock USB ports, you’ll need the tool’s password in addition to the user’s.

With that being said, some more advanced features like alerts can elevate a tool. The lack of features like these holds the tool back the most. The tool has three licenses, with the Personal costing $29 and the Business costing $199.

7. BuduLock


BuduLock, made by Mouse Click Enterprises, is a free tool that provides password protection to any folder on your system. Although this is its primary purpose, it’s also capable of USB port locking, forcing password entry if a USB attempts to interact with your system. It doesn’t disable the USBs, meaning your USBs will generally work on systems without it.

Main Features

  • The most straightforward tool on this list
  • Entirely free of charge
  • Can lock and unlock folders in addition to USB drives

The tool has two primary tabs: Folder Lock and Flash Drive Lock. This gives it an extreme level of simplicity that’s difficult to match. In the Folder Lock tab, you can see a list of the drives on your system, as well as a simple tree view for picking folders. There are also two big buttons- Unlock and Lock.

This is probably the most straightforward tool on this list, preceding complex features or even a beautiful user interface for sheer simplicity. The Flash Drive Lock tab is similar in structure and highly intuitive. Not only is the tool simple enough for those of us that aren’t technically inclined, you most likely won’t even need to read a tutorial.

However, this simplicity comes at a cost. The UI is not very appealing, the tool is void of more advanced features, and it isn’t easily scalable. If you’re looking for an enterprise-level tool, this isn’t it. However, it can still be an excellent tool for personal use.

8. USB Disk Manager

USB Disk Manager

The USB Disk Manager is yet another lightweight USB port protection software that ensures all of your USB ports are protected from malware and the actions of malicious actors. This tool has some innovative features to set it apart from the rest.

Main Features

  • Completely free of charge
  • Extremely lightweight
  • Easy to use
  • Automatically installs itself on your USB drives
  • With that being said, the UI could use some cleaning up, and the tool lacks more advanced features for when you’re comfortable with it.

It has AutoCopy features that automatically install USB Disk Manager on your USBs as a portable application, which ensures you’ll never be without it. It also has an Autorun feature, so it’ll automatically start with the rest of your system.

The tool will block all users attempting to copy files to and from untrusted USB devices. It can also hide devices from your device entirely, in addition to stopping them from running any applications while plugged in.

Without proper authorization, it will also block existing applications or malware from accessing your USB devices. This tool provides everything you need in a simple USB port locking solution despite being free.

9. USB Drive Disabler

USB Drive Disabler

USB Drive Disabler is a small, portable software mainly aimed at enterprises. The focus on enterprises helps it cater its UI and features to an enterprise-level environment without worrying about performance for home users or SMBs.

Main Features

  • Specialized for enterprises
  • Has a silent mode which will not let users know that their device was blocked by the tool
  • Alert Mode allows you to be alerted whenever someone tries to access a blocked port
  • Lock ports on multiple devices at once
  • You can even block administrators from accessing the ports

The tool has a flexible alerts system. Unlike tools that will alert you after X failed attempts, this tool lets you set up when you want to be alerted. Its Alert Mode will also alert you whenever a failed attempt or a drive is inserted into a blocked port.

Administrative privileges will also allow you to lock ports to multiple devices at once. This can be extremely useful for defending from a well-organized attack. If administrator access is compromised, you can even block all users so that not even administrators have access to the ports.

With that being said, the tool’s aesthetics are very outdated. Although it does a great job in the current climate, the tool is no longer updated, so it might be outdated in a few years.

Closing Words

As always, deciding on the ideal tool for you depends on your needs. Before you commit to any of these tools, you should look at what exactly you and your business need to get from it.
