After decades of providing a knowledge-exchange platform for the telecom security experts in Europe, ETIS in 2022 claimed the title of the European Telecommunications Information Sharing & Analysis Centre (ET-ISAC).

Activities of 7 (in total) working groups are jointly considered as activities of the ET-ISAC, bringing together more than 30 telcos and more than 20 other players in the telco ecosystem in Europe.

Senior Community & Programme Manager, Andrija Višić, manages the activities of the ISAC.

ETIS is proud to have gained this recognition as part of a multi-year project on mapping the activities of ISACs in Europe, conducted by CapGemini. The said project also resulted in the foundation of the EU Council of ISACs, an informal initiative which aims to coordinate the work of ISACs in Europe.

The above mentioned working groups meet several times a year via major conferences and webinars, through which they exchange sensitive information in a closed environment and clear TLP rules.

Our sharing rules are available here.
