SecuriCDS DD1000i

High assurance data diode with integrated proxies

SecuriCDS DD1000i is a data diode appliance that
enables unidirectional data flow and physical network
separation using optical technology. The DD1000i has
built-in proxy software from Advenica enabling a variety
of use cases.

Unparalleled protection against cyber threats

Data diode solutions provide confidentiality and integrity for sensitive networks and systems, preventing any potential backflow of information or unauthorised access from the outside.

Common use cases include file transfer between networks with different classification, or data export from networks of critical infrastructure or Industrial Control Systems (ICS). The Advenica SecuriCDS DD1000i provides network separation using optical technology and has built-in support for all typical data diode applications in one appliance.

Streamlined integration

The use of a data diode often requires the interfacing systems to handle proxy functionality, needed for any application requiring bidirectional communication.

The SecuriCDS DD1000i comes with integrated proxy servers and can run all application specific data diode services available from Advenica.

Support for multiple use cases is provided in one 1U 19’’ appliance, reducing both system complexity and total cost of ownership.

Meeting the highest security demands

The SecuriCDS DD1000i meets the highest demands on both security and assurance. The unidirectional data flow is guaranteed by a separate hardware component isolated from the integrated proxies. Special attention has been given to eliminate the risk of covert channels in the reverse direction.

The SecuriCDS DD1000i is approved in Sweden for data transfer between networks of different security levels up to and including the level of HEMLIGT/KVALIFICERAT HEMLIGT i.e. SECRET/TOP SECRET. Non-public approvals available in other European countries.

Some security challenges where datadiodes are a good solution

Traceability and security logging

Centralised logging in security-sensitive systems involves an enhanced risk of attacks. To reduce the risks, a solution is needed that protects both log data and all connected systems. Read more about traceability and security logging.

Secure transfer of SCADA information

To transmit critical information, e.g. from a SCADA system to an administrative office network means potential security risks. But there are solutions that take care of security problems and at the same time enables an exchange of information. Read more about secure transfer of SCADA information.

Secure updates

Updates for Windows and Linux systems are an important part of maintaining the security of the digital information in these systems. However, the updates themselves may be a security risk – to avoid these risks and to maintain the integrity and availability of the systems and be able to make secure updates, special solutions are required. Read more about secure updates.
