secunet Security Networks AG

Summary

When Germany’s government moved from Bonn to Berlin, sensitive information needed a safer way to travel too. In 1999, the Federal Office for Information Security, the BSI, commissioned secunet to develop SINA, a system for handling classified information digitally. secunet Security Networks AG had become an independent company just two years earlier, after separating from TÜV Mitte AG.

Today, the Essen-based company sells protected computers, encrypted network connections and security services to public authorities and businesses. SINA keeps different working environments separate and protects the information moving between them. The wider portfolio includes cloud infrastructure, digital identity and border-control systems. The job is to let organisations use sensitive data while controlling who can reach it.

Customer value

• Keeping sensitive work moving: SINA lets authorised staff use protected information in the office or on the move. Organisations can support digital working while meeting the requirements of the specific approved configuration.
• Managing security as a system: Customers buy coordinated hardware, software and services. Central management helps IT teams maintain protected workplaces and network connections across an organisation.
• Running regulated services in the cloud: secunet’s cloud offering hosts applications and data in German data centres. Its encryption, access controls and operating services help customers use cloud infrastructure within their security requirements.

What sets it apart

secunet Security Networks AG has long experience of turning government security requirements into products people can use. The BSI relationship behind SINA stretches back to 1999, and the product family covers both the workstation and its network connection. That combination matters when an authority needs a complete approved setup.

Approval belongs to a particular product, version and configuration; it is not a stamp for every possible installation. The same focus also concentrates the business: public-sector customers generated 94.2% of revenue in the first half of 2026. Procurement decisions and public-project schedules therefore carry considerable weight.

Growth plans

secunet Security Networks AG is investing in product development and expanding its organisation to support growth. Its August 2026 results identify demand from defence, homeland security and public authorities as drivers of the core business. The company is also developing cloud services for organisations with strict security and data-control requirements.

Its planned ServiceNow offering extends that approach to business workflows. Announced in October, it would run in German data centres under secunet’s operating control for public bodies and companies with strict security requirements. Availability is expected during 2027, so this is a planned service rather than a completed rollout or a disclosed new revenue stream.
