The helpdesk function is entrusted to CERTssh, an organization for and by tenants. Members live in one of the SSHnet buildings, and have knowledge of and interest in computer networks.
CERTssh is supported by an SSH appointed coordinator, who takes care of planning, and checks day-to-day operations. Moreover, there is an independent moderator who establishes and maintains the policies, after consultation with members and tenant (-organizations) as required.


In close coöperation with the network management company and sister organizations such as SURFcert, CERTssh checks the availability of SSHnet and takes action on incidents such as virus outbreaks or denial-of-service attacks.
