USB-C Port Lock PRO: physically block unused USB‑C ports

The Smart Keeper USB-C Port Lock is a physical security device that blocks unused USB‑C ports. By placing the lock directly in the USB‑C port, you prevent unauthorized users from connecting devices, copying data or introducing malware. This adds an extra physical security layer on top of your logical endpoint and device security.

Why secure USB‑C ports?

USB‑C is standard on modern laptops, desktops and docking stations. Through a single port, data, power, video and network all run. An unwanted device connected to this port can have an immediate impact on security, stability and compliance. With a USB‑C Port Lock, you ensure that only pre‑authorized ports can be used.

What does the USB‑C Port Lock do?


Physically blocks unused USB‑C ports so that no plugs or devices can be connected
Prevents unauthorized connections, data exfiltration and malware via USB‑C
Protects against wear or damage to ports caused by frequent plugging and unplugging
Provides a clear visual indication that the port is managed by IT/security


Concrete use cases by environment


Meeting rooms & flexible workspaces Laptops and docking stations in shared spaces are often left unattended. USB‑C Port Locks prevent visitors or colleagues from connecting their own hubs, adapters or storage
Public counters & receptions PCs and kiosks are physically accessible to visitors. Blocked USB‑C ports close off the path for “quickly” plugging in a USB‑C stick or device
Education & computer labs In classrooms and exam rooms, devices are shared between students. By physically blocking USB‑C, only school‑approved devices can be used
Healthcare & medical workstations For medical PCs and equipment, continuity is critical. USB‑C Port Locks prevent personal equipment from being connected outside validation and change processes
Critical infrastructure & OT In industrial and OT environments, you want USB‑C to remain closed by default. Only authorized engineers gain access via controlled procedures


Removal only with Lock Key Mini / Universal Lock Key

Removal is only possible with the corresponding Lock Key Mini. This allows you to centrally define which USB‑C ports are open or closed and aligns with a Zero Trust and NIS2 oriented approach to physical access.
