Creating advantage
4Secure delivers sovereign, vendor-agnostic Cross Domain Solutions (CDS) that enable controlled, secure data transfer between networks of differing classification levels.
Our technology and expertise help Defence and Government organisations prevent data leakage, stop malicious content, and enforce mission-specific information policies without slowing operations.
The result is reduced risk, assured compliance, and the confidence to share information when and where it matters most.
What are Cross Domain Solutions?
A Cross Domain Solution is a cybersecurity control that enables secure, policy-enforced exchange of information between networks at different classification levels.
Cross Domain Solutions can be bidirectional or unidirectional.
Every transfer is inspected, filtered and validated before release so only authorised, known-good data moves between domains.
Outcomes of Cross Domain Solutions:
Secure-by-design for all
At the heart of all 4Secure solutions is TrustedFilter®, a cybersecurity software solution developed by 4Secure to enable secure and seamless movement of data across environments that have different security requirements.
Enhancing traditional security frameworks, TrustedFilter® normalises, inspects and verifies data at the content level, working alongside firewalls and other technology to strengthen overall protection.
Deployable both on-premise and in the cloud, TrustedFilter® brings data assurance that was previously only available through specialist hardware.
