Government contractor cybersecurity, explained clearly and implemented practically.

Plain-language guidance on the cybersecurity requirements that attach to federal contracts — FAR 52.204-21, DFARS 252.204-7012, CMMC, CUI, NIST SP 800-171, FedRAMP, incident reporting, and the clauses that turn cybersecurity into procurement risk.

Start Here: The Baseline You Already Owe

Before any FAR or DFARS clause applies, federal and state law already requires your business to secure data and report breaches — the FTC Act, all-50-state breach laws, and rules like GLBA and HIPAA. The contractor requirements build on top of that legal baseline. Make sure you meet it first.

The FAR CUI Rule Is Back for Comment — What Changed and Why the 72-Hour Clock Matters

On June 23, 2026, the FAR Council reissued its proposed FAR CUI rule under a new docket, FAR Case 2026-001, reopening it for public comment through July 23, 2026. Here is what changed since the January 2025 draft — a longer incident-reporting window, a shift toward NIST SP 800-171 Rev. 3, a deleted clause, and a new conflict-of-law notice — and what a contractor should do with a proposed rule versus a final one.

Cybersecurity Flowdown: What Prime Contractors Owe Their Subcontractors

Prime contractors must flow cybersecurity clauses down to subcontractors that handle covered defense information — but the obligation goes beyond clause insertion. DFARS 252.204-7012(m) imposes a determination duty, an incident-notification requirement, and a CMMC verification obligation that many primes overlook.
