FIRST Welcomes New Members and Thanks Sponsoring Teams!

FIRST has welcomed 64 new members over the second semester of 2025: 39 Teams, 23 Liaisons, and 2 Associates.

Most growth comes from new Teams and Liaisons from the US (+9), Dominican Republic (+7), Taiwan, Province of China (+5), Switzerland (+3), Germany (+3), Great Britain (+3), Republic of Korea (+3), and Mexico (+3).

Overall at the end of 2025, FIRST community covers 116 countries, and is composed of 824 Teams (+87), 4 Associates (+4), and 202 Liaisons (+44).

FIRST aspires to bring together incident response and security teams from every country across the world to ensure a safe internet for all. Part of the FIRST mission is Global Coordination - you can always find the team and information you need. This is not possible without the support of teams who sponsor new members to join the community each year. A huge ‘THANK YOU’ to all sponsors who committed to doing the on-site or virtual site visits, supported applications, and provided recommendations.

Special recognition to the 4 teams that served as primary sponsors for three teams or more in 2025:

  • Switch CERT (5)
  • Team Cymru (5)
  • KrCERT/CC
  • TeleDCIS CERT
