Best USB Port Locking Tools

Do you know that 60% of data breaches are insider threats? Also, the average cost of each of these threats is a whopping $11.5 million. These numbers clearly show the widespread prevalence of these thefts and the huge impact it has on an organization. More importantly, these high numbers emanate from the fact that these threats are hard to identify and mitigate.

Typically, insider threats are done by employees who have legitimate access to sensitive information. They tend to steal this information and sell it to others for money or use it to settle a grudge against the organization itself. Regardless of the reason, an organization must take the necessary steps to protect its assets from insider attacks.

One such strategy is USB port locking.

Here is our list of the best USB port locking tools:

So, how do you know if any of the above tools are appropriate for your business needs?

Well, it all starts with research where you understand each tool’s detailed features, so you can determine the best fit. To ease your efforts, we have done the hard work, so sit back and read through the detailed feature list of each tool.

What is USB Port Locking?

Many times, employees prefer to download important documents to a USB flash drive because it’s easy to carry. Also, it’s hard for an organization to know that some files have been copied to a flash drive. Due to these reasons, an employee can get away with this stealth act.

The good news for organizations is that there is USB port locking software that prevents anyone from copying files to a USB drive. This acts as a deterrent for employees with privileged access to steal sensitive information.

Another advantage of this software is that it prevents employees from infecting computers with malware, ransomware, or other malicious software through a USB flash drive.

Due to these security advantages, organizations increasingly prefer to use USB port locking software to prevent any form of an insider attack.

The Best USB Port Locking Tools

Our methodology for selecting port locking tools and software

We reviewed various port locking tools and analyzed the options based on the following criteria:

  • Ability to lock and unlock USB ports quickly and effectively
  • Support for locking down other media, such as CD drive and Bluetooth
  • Graphical interpretation of data, such as charts and graphs
  • A free trial period, a demo, or a money-back guarantee for no-risk assessment
  • A good price that reflects value for money when compared to the functions offered

1. ThreatLocker Storage Control – GET DEMO


ThreatLocker Storage Control provides a method to manage all peripheral devices that can connect to a computer through a USB port. The ThreatLocker system monitors all of the endpoints on a protected network and all of the USB ports on each. The system starts by blocking all ports and then allowing an administrator to make some ports active for specific USB devices.

Key Features

The important features of ThreatLocker include:

  • Security Policy Creation Every business needs to have a company-wide security policy, which dictates who can access which resources. One of the features of the ThreatLocker system is a section that lets the administrator formulate a security policy that applies to all access rights for each user. The Storage Control module implements one part of the security policy. The console provides an access rights manager (ARM) that maps permissions for a user to use a software package to access a specific resource, such as a file folder or a USB storage device.
  • USB Port Controls The ThreatLocker Storage Control module manages all of the USB ports of all of the computers on a business’s network. The tool starts off with the policy of blocking all USB ports by default. The system administrator can then set up a permission structure for each port and specify USB devices that are allowed to attach to each computer. Users can also initiate the authorization of a device by inserting it into a port. Although all ports are blocked, they are still able to communicate with the central console of ThreatLocker. The insertion of a device provokes a notification in the console and the systems administrator has the option of approving it or leaving the block in place.
  • Activity Logging The ThreatLocker system logs all actions related to file access and file movements. So, if an authorized user is allowed to move a file onto a USB storage device, that event will be recorded. The log record includes the identity of the user, the file that was moved, the direction of the movement, the device it was moved or copied to, and the date and time of the event. These logs are stored and will be compiled into compliance reporting and can also be used to trace the source of disclosure if the file movement is later discovered to have been ill-advised.


  • Blocks all USB devices by default
  • Authorization identifies each USB device by serial number
  • Approve a USB stick for a computer, for a user, or a combination of both
  • Option to approve a USB device for system-wide use
  • Works on Windows and macOS


  • Doesn’t operate on computers running Linux

ThreatLocker is our top pick for a USB port locking tool because it shuts down all USB ports by default, so there is no danger of a system administrator oversight resulting in ruinous data theft. Instead, the worst that can happen is that some workers will be temporarily inconvenienced. However, the ThreatLocker system has a mechanism that caters to the occurrence of block processes: inserting a USB provokes a pop-up through which the user can make an urgent request to the administrator.

2. ManageEngine Device Control – FREE TRIAL

ManageEngine Device Control

ManageEngine Device Control is advanced software that prevents anyone from copying data to peripheral devices. It’s a simple and highly effective tool to prevent any insider attack or data loss.

Key Features

Let’s now look at the features of ManageEngine Device Control.

  • Comprehensive Control This tool provides comprehensive control over all ports and removable devices. It follows a zero-trust security model, so every time a user logs into a device or uses its USB ports, this information is logged in the audit section. Admins are also alerted during such attempts, and all these can deter employees from copying sensitive information to peripheral devices. You can also use this tool to create a trusted device access list. Any device that’s not a part of this list can’t access the USB port. Further, it creates a layer between computers and removable devices, so no malware can impact your network.
  • Streamlines File Access Device Control streamlines file access by encouraging you to set certain parameters. For example, you can implement a strict role-based access policy to allow readers only to read a file and not copy them to devices. Similarly, you can set the maximum file size that can be downloaded. This is an advantage because most times, sensitive information is grouped and stored in a master file. Above everything, this tool allows you to monitor file usage and actions as they happen, so you can always stay on top of insider attacks.
  • Generates Reports Device Control logs every file activity. It also maintains a record of devices and computers and users that access them. Since every information/activity is logged, you can generate reports at any time for internal viewing and auditing. Further, you can also use it to comply with industry standards. Thus, these are some of the important features of ManageEngine Device Control. In all, this is a comprehensive tool that provides complete control over file access and usage. Plus, the fact that it logs every access and login acts as a big deterrent for employees looking to commit insider thefts.
