Electricity Information Sharing and Analysis Center

Celebrating 25 Years of Leadership and Collaboration

This year marks the 25-Year Anniversary of the Electricity Information Sharing and Analysis Center (E-ISAC). Established in 1999, the E-ISAC was created to reduce cyber and physical security risk to the North American electricity industry through information sharing, curated analysis and security expertise.

The E-ISAC gathers and analyzes security data, shares appropriate data with stakeholders, coordinates incident management, and communicates mitigation strategies with stakeholders. The E-ISAC, in collaboration with the Department of Energy (DOE) and the Electricity Subsector Coordinating Council (ESCC), serves as the primary security communications channel for the electric industry and enhances industry's ability to prepare for and respond to cyber and physical threats, vulnerabilities, and incidents.

The E-ISAC is operated by NERC and is organizationally isolated from NERC’s enforcement processes.
The E-ISAC: 
  • Gathers,​ analyzes, and shares cyber and physical threat alerts, warnings, advisories, notices, and vulnerability assessments security information provided by members;
  • Provides an electronic, secure capability for E-ISAC participants to exchange and share information on all threats to defend critical infrastructure;
