A new report from Americans for Responsible Innovation is urging the U.S. government to designate the artificial intelligence sector as critical infrastructure and assign CISA as the lead agency for managing its cyber risk. The proposal defines the sector broadly, covering frontier models, model weights, evaluation and alignment systems, datacenters, AI-specific hardware, semiconductor chips, and deployment platforms, and argues that attacks on any part of that stack could cascade into other critical sectors.
The push reflects rising concern over both cyber and physical threats to AI infrastructure, including supply-chain disruption and attacks on datacenters. Supporters cited in the report say a critical-infrastructure designation would give AI companies and operators access to stronger federal incident response, cybersecurity tooling, and threat intelligence through the existing sector risk management framework, while former officials also warned that naming a federal lead for AI security could create bureaucratic friction as U.S. policy evolves.
