Telecommunication Information Sharing and Analysis Center (T-ISAC): the industry’s cybersecurity threat intelligence community

One organisation’s detection is another’s prevention

The rising complexity of cybersecurity and its rapidly evolving threats mean the industry must adopt innovative yet proven methods to stay ahead. This is the purpose of the GSMA Telecommunication Information Sharing and Analysis Center (T-ISAC). It serves as the central hub for intelligence sharing across the telecommunications industry, strengthening cyber defences and reinforcing the foundations for the connected future ahead.

With cyberattacks growing in volume, T-ISAC is a necessary component of security strategy. In Q3 2024, organisations faced an average of 1,876 cyberattacks per week, a record high, up 75% year-on-year and 15% from the previous quarter. No organisation can afford to face that scale of risk alone.

If you’re a GSMA member, you can join now by completing our short registration form, and start taking part in upcoming activities.

A key benefit of T-ISAC is that when we face the same challenge, we draw on global monitoring and collective data to block fraudsters and attackers. The power of the community makes the industry more responsive to the threats we face today.

T-ISAC brings together telecom operators, equipment providers, and experts to share cyber threat intelligence in a secure, member-only environment. It’s a community built on trust, shared purpose, and technical insight.

Members gain access to curated data, real-time threat intelligence, and peer-to-peer best practices. We facilitate meaningful exchanges – not just alerts, but context, indicators, and patterns.

But this is not only a data exchange platform, T-ISAC also facilitates action. Our platform supports technical and non-technical sharing, providing the opportunity to engage with industry experts. Our year-round calendar of events and training, T-ISAC helps members stay prepared.

As a member-led community, we rely on what our participants see and share. The more each organisation contributes, the stronger our collective defence. Sharing isn’t just encouraged, it’s how we scale early warning into active prevention.
