RECOGNITION AGREEMENTS
In order to avoid multiple certification of the same product in different countries a mutual
recognition of IT security certificates - as far as such certificates are based on ITSEC or CC - under
certain conditions was agreed.
European Recognition of ITSEC/CC – Certificates (SOGIS-MRA)
The SOGIS-Mutual Recognition Agreement (SOGIS-MRA) Version 3 became effective in April 2010. It
defines the recognition of certificates for IT-Products at a basic recognition level and, in addition, at
higher recognition levels for IT-Products related to certain SOGIS Technical Domains only.
The basic recognition level includes Common Criteria (CC) Evaluation Assurance Levels EAL 1 to EAL
4 and ITSEC Evaluation Assurance Levels E1 to E3 (basic). For "Smartcards and similar devices" a
SOGIS Technical Domain is in place. For "HW Devices with Security Boxes" a SOGIS Technical
Domains is in place, too. In addition, certificates issued for Protection Profiles based on Common
Criteria are part of the recognition agreement.
The new agreement has been signed by the national bodies of Austria, Finland, France, Germany,
Italy, The Netherlands, Norway, Spain, Sweden and the United Kingdom. The current list of
signatory nations and approved certification schemes, details on recognition, and the history of the
agreement can be seen on the website at https://www.sogis.eu.
The SOGIS-MRA logo printed on the certificate indicates that it is recognised under the terms of this
agreement by the nations listed above.
