Eight US telcos form a joint network cybersecurity group

For these operators, the immediate gain is a formal channel for sharing threat information and coordinating response across eight major US networks. That matters because the group brings together wireline, wireless and broadband providers under one cybersecurity effort, with AT&T, Charter, Comcast, Cox, Lumen, T-Mobile, Verizon and Zayo all named as participants. What to watch: whether the group publishes any concrete operating details beyond information sharing and rapid response, such as membership rules or threat-handling procedures.
