About secunet

secunet Security Networks AG is a German cybersecurity company headquartered in Essen, providing a portfolio of products and consulting services. The company was founded in 1997 as a spin-off from the IT division of TÜV Mitte AG. Since 2009, Giesecke+Devrient has been the majority shareholder, a partnership that helped accelerate growth. The firm operates through two primary segments, Public Sector and Business Sector, with the majority of its revenue generated from public-sector clients. Its business model involves the sale of security hardware and software, licenses, maintenance contracts, and providing consulting and implementation services. The client base includes German federal ministries, defense and space agencies, police forces, and more than 20 DAX-listed corporations, as well as international government organizations. As a key IT security partner to the Federal Republic of Germany, secunet has a strong position in markets that prioritize certification, data sovereignty, and long-term trust. A premier offering is the SINA (Secure Inter-Network Architecture) product family, a line of hardware and software co-developed with Germany's Federal Office for Information Security (BSI) for processing and transmitting sensitive and classified information. The SINA portfolio includes network encryptors, secure workstations, and encrypted communication devices accredited for use up to NATO and EU SECRET classifications. Other key products include 'secunet easygate' for automated border control systems at airports and 'secustack' for highly secure cloud platforms. In 2022, secunet acquired SysEleven, a German cloud infrastructure provider, to significantly expand its offerings in cloud and cloud security. The company is listed on the SDAX of the Deutsche Börse under the ticker YSN. For the first quarter of 2026, the company reported consolidated revenue of €81.8 million and a significant increase in order intake to €143.0 million.
