The Best USB Port Locking Tools

Best USB Port Locking Tools

Scott Pickard UPDATED: October 31, 2023

Restrict access to your USB ports to secure your network from data loss and USB-propagated viruses.

Your internal network security has always been at risk from removable hardware. Once such devices leave your network architecture, you can no longer trust their security once they return to your network. You are unable to ensure they haven't been exposed to vulnerabilities since during the time they were outside of your network, they were out of the reach of your security procedures.

Network administrators are in the constant conflict of preventing critical data loss and USB-based malware, while still enabling users to take their flash drives home. The simplest solution is to secure your USB flash drives because they are one of the main sources of such threats. For example, a computer may unintentionally pick up a virus that spreads itself to your USB flash drives, but this form of threat need not originate from a USB flash drive and can instead originate from any place in your network.

This means that to be safe, you need to attack the problem from both external and internal perspectives: you need to protect your company's USBs and any devices that might connect to them. There are several ways that you can do this, but one of the simplest ways is through the application of USB control software. This software can help you lock port access and blacklist unregistered USB external drives.

Here is our list of the best USB Port Locking Tools:

Infected USB Risks

Between 2010 and 2015, the practice of disseminating deliberately infected USB drives in public arose as an odd but unexpectedly efficient method of spreading malicious software. Curious people would pick up these flash drives, plug them in at work or school, and then spread whatever dangerous software was on the firmware throughout the network.

Although this technique is frequently used with USB flash drives, it should theoretically work with any device that connects to a USB port. As a result, be wary of any unknown peripherals, and as a network administrator, make sure to warn and instruct your users about the risks of plugging in arbitrary USB devices.

Malicious viruses merely infect a host device, such as a laptop PC, and when a USB drive is connected, it modifies the firmware of the drive to spread the same infection to any devices it connects to. It can swiftly propagate malicious firmware throughout an entire company, then to other firms and beyond by repeating the same cycle of virus-based USB firmware.

Due to increased awareness of the risks associated with plugged-in wild USB devices, this problem has decreased in frequency in recent years. However, it is still something to think about, particularly given the market's dominance by USB-centric devices.

Data Loss

USB external drives are also a major source of data loss, owing to the fact they can quickly transfer vast quantities of data with internal access. There are several ways to prevent data loss that strikes at the heart of the issue; namely better internal security, data restrictions, and other more applicable methods. However, a simple solution for many is to employ USB control software to restrict USB access and encrypt USB accessible data on your network.

USB Control Software

Device control software is one of the best solutions you can use for your network. This software keeps track of and regulates any data moving between the devices on your network and any portable storage, such as USB flash drives. Data Loss Prevention (DLP) software and device control software go hand in hand, and you'll note that several device control solutions are included in full DLP software suites.

You can use device control software to physically ban any unwanted USBs on your network by giving a single point of control for all connections from external devices. As an alternative, if you continue to let flash drive connections, you can keep track of the data sent and mark those that might be dangerous.

This article discusses 6 different USB Port Locking Tools that will allow you to completely restrict USB access on your network.

The Best USB Port Locking Tools

1. ThreatLocker Storage Control – GET DEMO


ThreatLocker Storage Control is part of a suite of system security tools and it provides activity logging for file movements as well as controls over the use of USB devices on a site. The Storage Control system integrates the monitoring of file movements into a system-wide data protection policy, which is formulated through a central console. By default, all USBs are blocked from attaching to any computer on the network.

Key Features:

  • Default block on all USB devices
  • User requests for deployment
  • Centralized controls
  • Location checks
  • Activity logging

The central console includes controls over many aspects of system security apart from USB device control through the other modules of the ThreatLocker platform. These enable data and applications to be ringfenced, only allowing specific applications to access specific data stores and for listed users. This is an expansion of a typical access rights management system that usually only amps user permissions to resources or to software. The ThreatLocker combines user, resource, and application in a permissions combination.

ThreatLocker doesn’t publish a price list. The tool can also be deployed in combination with remote monitoring and management tools, including N-able N-sight, NinjaOne RMM, and Atera. You can get to know the ThreatLocker system by accessing a free demo.
