Eight of the nation’s leading communications companies – AT&T, Charter, Comcast, Cox, Lumen Technologies, T-Mobile, Verizon, and Zayo – have established the Communications Cybersecurity Information Sharing and Analysis Center, known as C2 ISAC. The new non-profit is dedicated to strengthening cybersecurity across the communications sector.

Cyber threats have grown more sophisticated and complex, and they are evolving rapidly with Artificial Intelligence. This environment underscored the need to reassess and strengthen the sector’s frameworks for faster, more actionable information sharing.

Comarch

C2 ISAC builds on decades of public-private collaboration with the National Coordinating Center for Communications, also known as the Communications ISAC or COMM-ISAC. It was established in 1984 to promote resilience and information sharing among government agencies and private communications and IT companies.

A New Era of Cyber Collaboration

The U.S. telecommunications sector recognizes the urgent need for robust, unified defenses in the face of persistent threats to networks and consumers. The founding members formed C2 ISAC because no single company has full visibility into every threat or can address every risk alone. By sharing resources, expertise, and real-time intelligence, C2 ISAC helps members anticipate, identify, and respond to cyber threats more quickly and effectively.

C2 ISAC provides a trusted setting where technical experts can share information and coordinate defense strategies. This will help strengthen member organizations and boost the resilience of the nation’s critical communications infrastructure.
