Understanding CDS

This section builds your understanding of cross-domain solutions from the ground up.

What is a CDS? -- Formal definitions, the critical distinction from firewalls, a brief history from 1970s security models to today's multi-billion-dollar market, and how CDS relates to multi-level security.

Why CDS Matters -- The information sharing dilemma that CDS solves, real-world contexts from intelligence to critical infrastructure, what happens without CDS, and the growth drivers behind a market projected to reach $7.29 billion by 2031.

The Three Types of CDS -- Every CDS product is an access solution, a transfer solution, or a multi-level solution. This page explains each type with plain-English analogies, compares them in a table, and helps you work out which type you need.
