# Eight Leading U.S. Communications Firms Form C2 ISAC to Strengthen Cybersecurity Collaboration

In a significant move to safeguard critical communications infrastructure for the future, eight top communications companies in the US - AT&T, Charter, Comcast, Cox, Lumen Technologies, T-Mobile, Verizon, and Zayo - recently came together. The initiative, named the Communications Cybersecurity Alliance, aims to enhance cybersecurity measures for the sector. The alliance will focus on bolstering defenses against potential cyber threats and ensuring the security of vital communication networks. This collaborative effort underscores the importance of cybersecurity in an increasingly digital world, where breaches can have far-reaching consequences. The establishment of the alliance in May 2026 marks a pivotal moment in the industry's commitment to defense against cyber attacks.
