The Dutch Ministry of the Interior has renewed and expanded its contract for secure communications with Sectra. The contract extends over four years and comprises Sectra's Tiger solutions for secure communications and will be delivered as a service, in which Sectra assumes overall responsibility for the system. With Sectra's solutions, Dutch ministries and government o cials can communicate classi ed information relating to national security without the risk of eavesdropping. All Dutch ministries have used Sectra's secure communications service since 2007. The service comprises Sectra's solutions at the very high SECRET level, and the contract is now being extended to also include Sectra Tiger/R, Sectra's solution for the secure use of smartphones, at the RESTRICTED level. The Dutch ministries are thus gaining access to Sectra's entire ecosystem of secure communications solutions with full interoperability and can adapt allocation according to an individual's communication and security requirements, while still ensuring that everyone can communicate with everyone. Four levels of security--TOP SECRET, SECRET, CONFIDENTIAL and RESTRICTED--de ne how sensitive information is to be handled and the potential damage that its disclosure could cause. Communication of information that has been classi ed at these security levels requires that the communication equipment be reviewed and approved by an independent security authority. Sectra Tiger/S 7401 has been reviewed and approved for the SECRET security level by the Dutch security authorities and by NATO. Earlier versions of Sectra Tiger/S 7401 have also been approved by EU member states and individual nations, and Sectra is the only mobile crypto supplier with EU-approved solutions at this level.
