Contacting the TI

The preferred way to contact the TI team is by e-mail: ti@trusted-introducer.org


This mail address is monitored during normal business hours (09:00 to 17:00 on work days, timezone GMT+1, GMT+2 with DST according to EU rules).

As the TI team is using a trouble ticket system to track ongoing service events, for each new request a ticket number will be generated. This ticket number shall be used on all subsequent messages to make the life of each party involved easier and to avoid unnecessary ticket numbers.

Usually new requests and incoming information shall be processed within one working day, although for certain requests like team registrations, more time will be needed to clarify all open issues.

Service Governance

The TF-CSIRT Steering Committee is coordinating the activities of the Task Force including the Trusted Introducer Service.

Regarding the TI Service the TF-CSIRT Steering Committee has the following responsibilities:

  • Making decisions on TI Associates and TI Certifications in accordance with the guidelines agreed by the TF-CSIRT Community and processes established.
  • Reviewing the performance of the Trusted Introducer Service and making recommendations to modify or expand it.

Service Manager

The service manager responsible for the service delivery is Dr. Klaus-Peter Kossakowski. In case of special requests or service escalations please contact him directly. If needed use his PGP key to encrypt any email send to him.

The TI Team

The TI team consists of several members, all with a long history serving in incident response or security teams in Europe.

As all TI related communication is handled by an automated trouble ticket, we strongly advise you not to send any service related email to individual members of the TI team. No service can be guaranteed in such cases!
