Data Diodes

Unidirectional information exchange between networks

SecuriCDS Data Diode allow for real time, unidirectional information exchange between networks. Many networks require extra protection against manipulation and data leakage as they contain classified or sensitive information. Sometimes they are kept isolated for safe keeping. However, there are times when certain information has to be sent into, or out of, such networks. In such cases, a data diode can be of help.

SecuriCDS Data Diodes are one-way information transfer devices that connect two networks of the same or different security levels. The data diodes have an optical hardware separation to guarantee a unidirectional separation between the two networks.

Protecting Industrial Control Systems (ICS)

Connecting ICS systems to other networks pose a great security risk and security measures must be taken to prevent intrusion and to maintain the network integrity. SecuriCDS Data Diodes provides the most secure option as the information can only be sent out from the ICS network to e.g. the business network. This effectively mitigates the cybersecurity risks while enabling information transfer.

Safeguarding network confidentiality

Protected or secret networks have a very high security requirements regarding confidentiality. High assurance data diodes provide the necessary security safe guarding that no information leakage can occur – making sure that information leakage cannot occur. The use cases range from importing software updates or virus definitions to importing e.g. OSINT information to a secret analysis network.

SecuriCDS Data Diode Models

SecuriCDS DD1000A Unidirectional Data Flow

The DD1000A offers high performance in a small package, measuring only 216 x 167 x 44 mm. One or two DD1000A can be mounted in a 19" rack system using only 1U. DD1000A operates on Ethernet layer 2 and supports unidirectional protocols e.g. UDP.

SecuriCDS DD1000i Unidirectional Security Gateway

DD1000i includes integrated server hardware for proxies and can be mounted in a 19" rack system (height: 1U). This data diode model takes data protection to a higher level. By offering a powerful solution for efficient, risk-free data transfer between closed and open networks, proxies are designed, developed and tested to meet the requirements for interacting with highly sensitive information.
