CUI safeguarding requirements apply to the systems, people, and processes that touch this type of sensitive information — and this points to one of the most powerful levers in your entire compliance program: controlling how much of your environment touches CUI. If sensitive data flows through every inbox, laptop, and shared drive in your company, your compliance scope, and its cost, expands. Confine CUI to specific systems and users, and you can concentrate your efforts where they count.

A CUI enclave is an isolated environment purpose-built to house CUI. For small and mid-sized defense contractors especially, enclaves have become the most practical path to meeting security requirements without turning an entire IT infrastructure into a compliance project.

This section guides you through the complete enclave journey: what a CUI enclave is and how it works, the benefits a secure enclave delivers and when it's the right choice for your organization, whether to build one yourself or buy a managed solution, how to configure a defensible enclave architecture, and how to evaluate the vendor landscape when you're ready to compare your options.
