Their expertise in Cross Domain Solutions addresses one of the most demanding challenges in cybersecurity: enabling secure information exchange across environments with different security classifications. It is a capability that is increasingly critical for defence, government, and operators of critical infrastructure. Beyond their technical capabilities, we have been equally impressed by the people behind 4Secure. We see a strong cultural fit and look forward to building on their success together.”
