Eight of the most influential US telecommunications carriers — including AT&T, Verizon, T-Mobile, and Comcast — have established the Communications Cybersecurity Information Sharing and Analysis Center, known as C2 ISAC. Governed by the CISOs of each founding company and led by a director with CISA and FBI experience, C2 ISAC is designed to deliver real-time, actionable threat intelligence across competing carriers that collectively defend America's critical communications infrastructure. Operations are expected to begin in June 2026.
