CIS is Home to the MS-ISAC

As an ISAC member, you'll get access to a community that will help you stay up to date on cyber threats facing your industry.

For more than two decades, the Multi-State Information Sharing and Analysis Center® (MS-ISAC®) has provided foundational cybersecurity services to U.S. State, Local, Tribal, and Territorial (SLTT) governments. The MS-ISAC was historically funded by Congressional appropriations through a Cooperative Agreement (CA) with the Department of Homeland Security (DHS). However, with DHS’s decision to end its support for the SLTT community through the MS-ISAC, the organization transitioned to a fee-based membership model on Oct. 1, 2025. A division of the Center for Internet Security, the MS-ISAC is autonomously guided by its Executive Committee and member organizations to preserve and strengthen the cybersecurity collaboration that continues to protect communities nationwide.
