Encrypted within the internet: the VPN gateway to protect your data
On network layer 3 and secure on the open network: The VPN tunnel for secure data exchange

The holistic security concept of the SINA L3 boxes includes a hardened and evaluated SINA OS operating system, smartcard technology and IPSec-based cryptography for standardized all-round protection. The availability and reliability of SINA L3 Boxes can be increased by means of redundant configurations. In addition, SINA L3 Boxes also support geo-redundant and load-sharing configurations. The innovative SOLID technology enables automated VPN connections for VS-NfD networks. It always establishes the ideal data connection between the gateways. If devices fail or are added, the network reorganizes itself. The SINA L3 boxes are approved in various configurations from CONFIDENTIAL up to German national TOP SECRET (STRENG GEHEIM), NATO SECRET as well as SECRET UE/EU SECRET. SINA Management allows administrators to conveniently configure and manage all users and network components.
