USB devices are among the biggest security risks in the IT environment. They are small, portable and extremely easy to use – which is also their biggest weakness. All it takes is one unauthorized USB stick and an organization can face a data leak or security incident.
SmartKeeper solutions provide the answer to this problem: physical control of USB devices. The Link On (Professional product line) or Lockable Flash Drive / Lockable Flash Drive Plus (Essential product line) products take USB security to a whole new level. They are lockable USB flash drives with a high level of data security, designed for professional environments.
The lockable USB memory sticks Link On or Lockable Flash Drive / Lockable Flash Drive Plus are unique solutions that combine USB storage with physical security.
How they work:
- the USB memory stick is inserted into the port,
- then it is mechanically locked by pressing a button,
- its removal is only possible using a special key:
Result: The USB device cannot be removed or replaced without authorization.

Unlike regular USB sticks:
- the device can be locked in the port,
- the risk of theft or exchange is eliminated,
- protection against insider threats is increased.
Physical security vs. encryption: which is more important?
Common secure USB solutions rely on:
- passwords,
- encryption,
- software policies.
However, this does not solve the fundamental problem: the device can still be physically disconnected or replaced. SmartKeeper takes a different approach:
- blocks manipulation on a physical level,
- eliminates risk before data is accessed.
It is an ideal complement to encryption – not a replacement for it

SmartKeeper as part of a Zero Trust strategy
Modern organizations are moving to a Zero Trust model – trust nothing without verification.
SmartKeeper extends this principle:
- even physical access is controlled,
- even USB devices are subject to authorization,
- even a simple port is protected.
USB security starts with physical inspection
The SmartKeeper Link On and SmartKeeper Lockable Flash Drive / Lockable Flash Drive Plus products prove that data protection doesn’t have to be complicated.
Instead of endless software layers, they bring a simple rule – what cannot be physically manipulated cannot be abused. In an environment where USB devices pose one of the biggest risks, this is a solution that makes sense.
