Lock License USB Drives: Always Write Protected by Design
Lock License USB flash drives are write protected by default at all times. The device’s natural state is read-only, enforced directly by the USB controller firmware. Content cannot be modified, and malware cannot be written to the device.
Even if a user forgets to re-enable protection, simply removing the drive from the USB port restores the protected state automatically. Loss of power means protection is restored. This fundamentally changes how USB media behaves and closes one of the most common paths for malware transmission between systems.
Lock License does not restrict reading. Anyone can plug the drive in and access the files normally. A password or unlock action is only required when an authorized user needs to temporarily enable writing in order to update content.
How Lock License Works
Lock License behavior is applied during manufacturing at the controller firmware level. Devices ship in a permanently enforced default state of write protection. This is not software, not a driver, and not dependent on the operating system.
Authorized users can temporarily unlock the device using Nexcopy’s management utilities in order to update or replace files. Once the device is unplugged, protection is automatically restored. The drive always returns to its secure state without relying on user behavior.

Why This Write Protection
One of the most common ways malware spreads inside organizations is through infected USB drives. A user plugs in an unknown device, copies a file, or moves content between systems, and unknowingly transfers malicious code along with it.
With Lock License, this risk is eliminated at the device level. Because the drive cannot be written to under normal conditions, malware cannot infect the device, cannot hide on it, and cannot propagate to the next system.
This protects not only internal systems, but also brand reputation. Organizations distributing branded USB drives avoid the risk of their media being associated with malware incidents in the field.
Common Use Cases
Lock License USB drives are deployed in environments where both data integrity and malware prevention are critical. Organizations use Lock License when they need distributed USB media that behaves predictably and safely across uncontrolled systems.
Typical use cases include software distribution, healthcare workflows, training materials, internal corporate documentation, field documentation, controlled document delivery, compliance-driven distribution, and environments where USB devices regularly move between machines.
Why Lock License Instead of Other Write Protection Methods
- Software write protection: Can often be bypassed, removed, or disabled
- Mechanical switches: Prone to breakage, user error and forgetfulness
- Registry or endpoint policies: Do not travel with the device
- Lock License: Protection is built into the device and follows it everywhere
Lock License is designed for environments that require dependable behavior rather than user-dependent protection. The device behaves the same way on every system, every time, regardless of policies, permissions, or operating system.
