We welcome CIRA, the registry operator for .ca, to our TLD ISAC family, which now counts 25 members and represents more than 61 million domains under management!

Jon Ferguson, Vice-President Cybersecurity & DNS said: “No registry can secure the internet alone. By joining the TLD ISAC and working with Europe’s TLD community, CIRA gains trusted intelligence and shared expertise to strengthen security at home and abroad. As today’s threat landscape grows, collaboration increases everyone’s ability to succeed at their respective mission.”

Together with RNIDS (.rs) and Traficom (.f), CIRA is the third new member to join the TLD ISAC in 2026.
