Introduction
Lock-Keeper is a high-level security solution based on the simple idea of "Physical Separation". It is a hardware-based device and works like a sluice to provide secure data exchange between physically separated networks. Based on the simple principle that "the ultimate method to secure a network is to disconnect it" the Lock-Keeper can entirely prevent session-based and protocol-based network attacks (i.e. so-called "online attack") by physically isolating your sensitive network from external world.
Both the principle and architecture of Lock-Keeper are quite simple. It is not proposed to replace the functionality of the conventional firewall but generally used in combination with firewall to enhance the security of the protected network. Moreover, other security approaches, such as anti-virus software, content scanning tools, authentication modules and access control mechanisms, etc., can be flexibly integrated with Lock-Keeper to prevent some application-level attacks, also referred to as "offline attacks".
The Lock-Keeper system is manufactured and vended by Siemens Switzerland Ltd, Civil And National Security. Marketing, consulting and sales services are supported by Actisis GmbH. Research and development are conducted at Hasso-Plattner-Institute.

Application Scenarios
The guarantee of the highest-level security, the simplicity of the architecture, and the free scalability of the integrated application level security are the primary strengths of the Lock-Keeper solution. Thanks to these benefits, the Lock-Keeper can totally satisfy the security requirements from most public authorities, national defence institutions or companies with a highly sensitive IT infrastructure, such as:
- Military and governmental organizations
- Financial sections
- Energy suppliers
- Telecommunication companies
- Transportation companies
- Air traffic control
