Becoming a FIRST member

FIRST welcomes new members. There are two categories of membership:

  • Full Members are security incident response teams who assist a defined constituency in preventing and handling security-related incidents;
  • Liaison Members: individuals that have a legitimate interest in and value to FIRST.

Both types of members are able to enjoy the benefits of FIRST membership, such as access to SIGs, mailing lists and other services, but only Full Members have voting rights.

New members must be nominated by existing Full Members:

  • Two nominations for new Full Members;
  • One nomination for new Liaison Members.

The nominating Full Members are then called "sponsors".

If support is needed to find an existing FIRST Full Member as sponsor for your own application, please do not hesitate to contact the FIRST Secretariat (first-sec@first.org), and we can help identify potential sponsors. At least one sponsor must perform a site visit. Read more about Site Visit requirements.

More detailed information for potential members is available at the FIRST Membership Process section.
