On September 10, 2025, the Department of Defense (DoD) published a final rule (CMMC Clause Rule) that will apply its much-anticipated Cybersecurity Maturity Model Certification program (CMMC) to DoD contractors and subcontractors. Under the CMMC Clause Rule, starting on November 10, 2025, DoD can include CMMC requirements—potentially including third-party cybersecurity assessments—in contracts that require the handling of Controlled Unclassified Information (CUI) or Federal Contract Information (FCI).

What is CMMC?

CMMC is a unified assessment model created by DoD in response to the growing threat of cyberattacks and data theft from the defense industrial base. CMMC is designed to ensure that DoD contractors and subcontractors adequately safeguard two categories of sensitive government information: CUI and FCI.

D.C. Circuit Rules Pentagon Can Exclude Anthropic From Supply Chain

The U.S. Court of Appeals for the D.C. Circuit has ruled that the Department of War can exclude Anthropic from its supply chain under the Federal Acquisition Supply Chain Security Act, finding that the AI company's ability to manipulate its Claude model creates a supply chain risk. This decision contrasts with an earlier California district court ruling that blocked a similar designation under a different statute, creating a complex legal landscape for AI providers and government contractors.

BIOSECURE Act Update: Court Enjoins WuXi AppTec’s 1260H Designation, but Strategic and Compliance Clocks Keep Running

The U.S. District Court for the District of Columbia has preliminarily enjoined the Department of War from enforcing WuXi AppTec's Section 1260H designation, finding the agency misread its evidence on state and military affiliation.
