How shared intelligence could reshape cybersecurity across industries
Key takeaways
- Telecom providers are showing that cyber defense works better together than alone.
- AI is compressing the timeline between vulnerability discovery and exploitation.
- Real-time threat sharing helps teams respond faster and avoid reinventing the wheel.
- This alliance could become a model for cross-industry cybersecurity collaboration.
- As public-sector support weakens, private-sector coordination may need to fill the gap.
- Fear of legal exposure still stands in the way of broader intelligence sharing.
What is the C2 ISAC, and why was it created?
Eight providers of telecommunications services in the U.S. are circling their cybersecurity wagons to now share threat intelligence via the next iteration of a Communications Cybersecurity Information Sharing and Analysis Center (C2 ISAC).
AT&T, Charter, Comcast, Cox, Lumen Technologies, T-Mobile, Verizon, and Zayo have established C2 ISAC in the wake of cyberattacks such as the Salt Typhoon campaign successfully accessed call records and communications data. More troubling still, advances in artificial intelligence (AI) are raising concerns about software vulnerabilities that might be discovered and then exploited in a matter of hours.
Rather than trying to combat these attacks independently, telecommunication providers are extending previous efforts to share threat intelligence in real time to enable them to both detect and respond to attacks faster and, ultimately, contain costs. Otherwise, each telecommunications provider winds up spending time, money and effort on replicating threat intelligence research that may have already been done elsewhere.
Could this model work in other industries?
The question the C2 ISAC alliance raises, of course, is to what degree might similar alliances be formed across other industry sectors or, for that matter, between organizations operating in completely different industries. The simple fact of…
