Connecting the Disconnected

Cross-Domain Security


About 4Secure

For over two decades, 4Secure has specialised in cyber security consultancy, emerging as subject matter experts in Cross-Domain Solutions.

4Secure’s innovative cross-domain solutions allow clients to access their data securely and seamlessly by connecting environments operating at different security classifications that would otherwise be disconnected.


Cross-Domain Solutions

Cross-domain solutions (CDS) combine hardware and software to securely transfer data between environments operating at different security classifications that otherwise remained isolated. 

This empowers organisations to fully harness data intelligence and increase their organisational efficiency. Cross-Domain Solutions can be unidirectional or bidirectional.
