OpenAI expanded its Trusted Access for Cyber (TAC) program to federal, state, and local governments, broadening a defender-access system for cyber response and critical-infrastructure support. The move ties TAC to GPT5.4-Cyber and extends access into missions such as public health, emergency management, and benefits delivery. It could make authenticated AI assistance more available to public-sector defenders while narrowing access to vetted users.
