What is an Isolated Network?

From government and defence to finance and critical infrastructure, many organisations have networks which contain sensitive information or run critical processes that are isolated from their main corporate networks.

Why You Need a Cross Domain Security Solution


Organisations need to exchange information between their isolated and corporate networks to ensure business continuity, for example extracting reports from an industrial control network or bringing unclassified information into a classified network to work on it.

To do this safely, it is essential to protect the isolated network so that malware is not imported in and sensitive data is not accidentally or maliciously exported out.

A cross domain solution enables information to be exchanged between isolated and corporate networks in a controlled manner with a high level of assurance that the isolated network cannot be compromised.

The UK National Cyber Security Centre (NCSC) has published 13 security principles to use when building a cross domain security solution to protect an isolated network. Deep Secure is the only vendor with solutions that conform with the entirety of this guidance.
