DoD Zero Trust Strategy and Contractor Execution


A practical guide series for defense contractors turning Zero Trust goals into explicit access decisions, measurable controls, and reusable evidence. Start with the strategy, then connect architecture to GovCon cybersecurity and compliance.

Why This Series Matters

Zero Trust is easy to reduce to identity products and network diagrams. The real operating question is whether each access decision has an authority, resource, policy, signal, owner, result, and reviewable record.

Best Starting Point

The DoD Zero Trust Strategy Explained for Contractors

NIST SP 800-171 Explained: Requirements, Controls, and Compliance

NIST SP 800-171 is not a certificate or a product. It is the 110 requirements that decide whether you can hold Controlled Unclassified Information. This guide explains the standard, the 14 families, how SPRS scoring works, what Rev 3 changes, and the order to work the controls in.
