Nexus and Sonera SmartTrust Sign Letter of Intent Concerning Cooperation in Product Development and Sales within the Field of PKI Nexus and Sonera SmartTrust have signed a letter of intent concerning the outsourcing of the development of Digital ID, as well as the management of customers, sales, and support for fixed PKI products. The agreement is expected to increase Nexus' sales by over SEK 120 million during the next three years. Technology Nexus AB and Sonera SmartTrust AB have signed a letter of intent concerning the administration and development of SmartTrust's PKI products. The agreement also entails Nexus taking over operations and responsibility for sales and support of existing and new customers with regard to SmartTrust's products within the field of fixed PKI, primarily the products Certificate Manager, Security Center, and SmartTrust Personal. Concerned personnel within SmartTrust's Digital ID division are being offered employment at Nexus in conjunction with the agreement. In the future, SmartTrust will focus its PKI operations on mobile operators and OEM suppliers. Nexus will mainly work with business organisations, banks and finance companies, and state and local authorities. As a result of the agreement, the parties will work together with product and business development that furthers the development of PKI in both fixed and mobile networks. The parties will immediately begin preparations for implementation and the final agreement is expected to be ready at the end of June/beginning of July 2002. In this way, Nexus will strengthen its leading position as a supplier of secured PKI-based solutions in the European market. "Nexus views this development of the long-term and already good collaboration between SmartTrust and Nexus positively. Being able to combine our partner model on the development side with a strengthening of our ability to develop a number of long-term, strategically important customers within the field of PKI provides positive effects for Nexus and SmartTrust, and not least for our mutual customers," says Mikael Jacobsson, CEO, Nexus. "We have always said that in order to become the leader within secured solutions, we must be the best within PKI. This agreement further strengthens our leading position within this field - in Sweden and the rest of Europe," concludes Jacobsson. "With Nexus as a partner, SmartTrust has a good foundation for supplying solutions to mobile operators that function well together with the PKI solutions that Nexus supplies to other customers. Nexus also has considerably more comprehensive operations within security and system integration than SmartTrust, which we see as an important asset in order to be able to offer solutions that can utilise PKI in a more business- oriented manner during the next development phase. We see this as a unique collaboration that considerably increases the competitive edge of both parties," says Antti Vasara.
