The Smart Keeper Link On 3 is not a regular USB stick, but a physically lockable flash drive with 128 GB of storage (optionally 256 GB or 512 GB) that you secure in the USB‑A port. This prevents anyone from simply taking or misusing the memory and turns a vulnerable USB port into a controlled, secure channel for data transfer within your network.
Physical USB security for critical systems
With the Smart Keeper Link On 3, you prevent random USB sticks or smartphones from being plugged into servers, industrial PCs or workstations. The drive is secured with a unique key, which means unauthorised removal or misuse is simply no longer possible and the risk of malware, data leaks and sabotage is drastically reduced.
Secure data transfer in IT and OT
This lockable flash drive is ideal for controlled exchange of firmware, configurations, log files and sensitive documents between segmented networks. Administrators can still do their work, but only via a storage medium that you have approved and that is physically protected. Ideal for data centres, production environments, government, healthcare and finance.
Supports compliance and audit trail
Because this lockable flash drive is part of your key and security policy, you can clearly demonstrate who moved which data and when. This makes audits, pen tests and customer reviews much easier and more credible. In combination with PortLocker from DataLocker for port and device control or an alternative such as secRMM with advanced logging and monitoring, you build a closed chain: from physical USB security to full visibility of all external storage media within your network environment.
Practical, manageable and future-proof
The Smart Keeper Link On 3 does not require any additional software or agents and has no impact on performance, keeping deployment and management straightforward. This allows you to add a powerful physical security layer without making the user experience unnecessarily complex – exactly what modern organisations need in a time of growing cyber threats.
