Nexus GB

About Us

Nexus have been making data rugged, portable and secure for over 25 years. We're the exclusive Datakey® distributor for the UK, Ireland, Germany, Austria, Switzerland and Scandinavia.

At Nexus we are entirely focussed on the Datakey product line, this allows us to give a high level of service and support to our customers. Because we are used to dealing with Original Equipment Manufacturers (OEMs) from many different industries, we understand that it can often take years for a product to come to market and we work with our customer to support them during this process. 

We don't simply sell keys or tokens but offer a range of portable memory products with matching readers as well. That's one of the reasons millions of our devices are being used across the UK and Ireland for data logging, cashless vending, security, access controls and much more.
