The main purpose of this legislation, known as the Extending Anti-Terrorism Protections Act of 2025, is to give the Secretary of Homeland Security the ability to temporarily extend protections for certain anti-terrorism technologies. This is intended to enhance the effectiveness of measures that help prevent and respond to terrorist threats. Key provisions of the Act include the authority for the Secretary of Homeland Security to extend protections for qualified anti-terrorism technologies until the end of fiscal year 2029.
