About us

secunet is one of Germany’s leading providers for superior IT security, and has been a security partner of the Federal Republic of Germany since 2004. At secunet, more than 500 specialists are focused on issues such as cryptography, e-government, critical infrastructure and automotive security. secunet’s main product portfolio SINA is a joint development with the German Federal Office for Information Security and consists of cryptographic devices for national and international customers with high security requirements. SINA enables secure process, storage, transfer and register of classified information up to and including classifications STRENG GEHEIM (Germany), NATO SECRET and SECRET UE. The diversity of secunet’s unique product range – comprising stationary and mobile clients, IPsec gateways and data diodes, Ethernet encryptors and a registry-compliant solution (SINA Workflow) – supports the creation of security domains for all manner of
application scenarios.

Products and services

The capacity to work on the move is increasingly important in the rapidly developing working environment. Workstations need to be flexible. There are high expectations in terms of convenience, security and efficiency, all at the same time. But frequently convenience and productivity are significantly restricted by Internet usage provisions and the handling of data; albeit that these are crucial to the necessary security.

With our SINA Workstation S, a mobile crypto client, and our ultra-mobile SINA Tablet S customers can communicate with server areas in a VPN-tunnelsecured manner – anytime, anywhere. A key component of the central IT infrastructure in highsecurity networks are our SINA L3 Boxes S. They connect public authority or corporate networks via the Internet. Even in complex networks high IT security can be achieved with low effort: With SINA SOLID (Secure OverLay for IPsec Discovery) a component of the SINA L3 Box S dynamic IPsec-based security associations are configured automatically.

SINA Workstation S

SINA Workstation S

The SINA Workstation is a fat client with a cryptographic file system and IPSec-protected communication. Protected by a VPN tunnel, it communicates with server areas or terminal server areas. This enables stationary or mobile, online or offline use. SINA networks can be accessed via wired (Ethernet) or wireless media. Emission-protected hardware platforms are required for approval purposes. The SINA Workstation S was specially developed for users with medium protection requirements.



As a VPN gateway, the SINA L3 Box is a key component of the central IT infrastructure in high-security networks. The data exchanged between the SINA components is securely transmitted via encrypted VPN tunnels. SINA L3 Boxes connect public authority or corporate networks via the Internet. In addition, access to (terminal) servers by SINA clients is provided via pre-switched SINA L3 Boxes, which serve as cryptographic network access points.

News & Innovations

EU SECRET Approval for SINA Workstation 

[Essen, 3 Nov 2017] Following NATO, EU has now also approved the high-performance SINA Workstation H crypto client for the EU SECRET classification level. This makes secunet the only German manufacturer to meet NATO and EU requirements for IPsec solutions to this high classification level.

SINA Workstation H has been specifically developed for users with high security requirements. On the one hand, it offers IPsec-secured transfer of data across any IP networks – as a counterpart to SINA Box H, approved for EU SECRET for some years. It offers unique multi-session capacity: For example, with SINA Workstation H, open data and classified data up to SECRET can be processed in parallel sessions, and stored locally with cryptographic separation. This feature is advantageous for use in the EU environment in particular, as users often need to process diverse classified information from a range of networks. SINA Workstation H enables them to process this information on a single device, instead of – as previously – having to switch between several workstations.
