Senate Bill No. 251, titled the "Louisiana Critical Infrastructure Protection Act of 2026," seeks to bolster the security of critical infrastructure in Louisiana against threats from foreign adversaries. The bill establishes a new Part B within Chapter 51 of Title 51 of the Louisiana Revised Statutes, which includes prohibitions on foreign adversaries accessing state critical infrastructure, assessments of vulnerabilities related to sanctioned communications equipment, and a ban on adversary cameras and laser sensor technologies in transportation systems. It also defines critical infrastructure and cybersecurity, and clarifies the authority to make operational decisions regarding critical infrastructure.

Significant changes to existing law include the removal of the requirement for companies to file a certification with the Governor's Office of Homeland Security and Emergency Preparedness (GOHSEP) to access critical infrastructure, as well as the elimination of provisions detailing GOHSEP's powers and duties. The bill also abolishes a provision against adversary network-connected devices and the Foreign Adversary Technology Rip and Replacement Fund. However, it introduces new exemptions for certain telecommunications providers and electric utilities, allowing them greater operational flexibility while still prioritizing critical infrastructure security. The act is set to take effect on August 1, 2026.
