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 the matter is organizations of all types and sizes are facing the same threats, so maybe the time has come to pool resources and expertise at a time when it’s all too apparent that cyberattacks are increasing in terms of both volume and sophistication.
Theoretically at least, government agencies such as the Cybersecurity and Infrastructure Security Agency (CISA) were formed to coordinate security defenses across the public and private sector. However, the resources allocated to those efforts have diminished. As such, it now appears that a heavy burden for coordinating efforts to detect and thwart cyberattacks is going to be placed on the private sector.
Why is threat intelligence sharing more urgent now?
Of course, many cybersecurity professionals have, both formally and informally, been sharing threat intelligence for years. The real challenge now is the pace at which attacks are being launched is approaching machine speed as adversaries leverage AI and other automation technologies for their own illicit purposes. Unless cybersecurity teams are able to more proactively discover threats and respond to them in near real time, the amount of potential havoc that could be wrought in a few minutes is approaching the incalculable.
Hopefully, there will come a day when organizations and nation-states treat cybercrime more like a scourge versus a series of disconnected unfortunate incidents. Adversaries with each passing day are becoming more organized. In contrast, defenders are operating in silos that require them to overcome major bureaucratic hurdles to share intelligence simply because organizations are afraid to share what they know for fear it might one day be used as evidence to prove some level of negligence.
Organizations clearly need more legal protections from lawsuits that might be launched against them. That doesn’t mean they should be completely absolved from being responsible for having lax defenses. However, it does mean some level of common sense needs to be applied to threat intelligence in the name of the greater good that now more than ever needs to be found much sooner than later.
