Information Sharing and Analysis Centers (ISACs) were created pursuant to Presidential Decision Directive 63 (PDD-63, May 1998), which provided a foundation for industry and government to form a public-private partnership to reduce vulnerability of America’s critical infrastructure.

ISACs are sector-specific platforms advancing physical, and cyber, critical infrastructure and key resource protection efforts by establishing and maintaining information sharing networks for operational interaction between ISAC members, government entities, and external partners. They typically serve as the strategic and operational arms for sector information-sharing efforts.

The PT-ISAC is a trusted, sector-specific entity which provides critical information and analysis using the Transit And Rail Intelligence Awareness Daily (TRIAD) Report.  The TRIAD provides ISAC participants with quick, easy-to-read synopsis and analysis . The PT-ISAC also offers a Cyber Daily Report and the Over-the-Road Bus Intelligence Awareness Daily (OTRBIAD) Report.
