BlackBerry Enterprise Solution is the First Mobile Platform to Achieve Common Criteria Certification

BlackBerry Enterprise Server and BlackBerry Device Software gain International security accreditation

Rome, ITALY – Research In Motion (RIM) (NASDAQ:RIMM)(TSX:RIM) today announced that its BlackBerry® Enterprise Server and BlackBerry® device software have been awarded Common Criteria Evaluation Assurance Level 2 augmented (EAL 2+) validations. The certifications were awarded at the 8th International Common Criteria Conference in Rome and acknowledge the robust security features of the BlackBerry® Enterprise Solution.

"RIM is a pioneer and longstanding advocate of wireless security and we are extremely pleased to report that our BlackBerry software has become the first mobile platform to receive the Common Criteria certification" said Mike Lazaridis, President and Co-CEO at RIM. "This certification, along with numerous other security accreditations from around the world, further illustrates why so many security conscious organizations and governments have chosen the BlackBerry solution."

The Common Criteria is an international standard for validating that IT products meet specific security requirements. The BlackBerry Enterprise Server and BlackBerry device software have been independently evaluated by a third-party Common Criteria evaluation facility and meet the security criteria for EAL 2+. This evaluation assurance level is accepted under the Common Criteria Recognition Arrangement (CCRA) by 25 countries including:

• Australia

• Austria

• Canada

• Czech Republic

• Denmark

• Finland

• France

• Germany

• Greece

• Hungary

• India

• Israel

• Italy

• Japan

• Republic of Korea

• Malaysia

• New Zealand

• Netherlands

• Norway

• Singapore

• Spain

• Sweden

• Turkey

• United Kingdom

• United States

In addition to the Common Criteria certifications, the BlackBerry Enterprise Solution has been approved for use under the rigorous CAPS program in the UK and has also had several FIPS-140 validations for its embedded encryption module. The solution has also uniquely been approved for the wireless transmission of sensitive data, up to the RESTRICTED classification, by NATO and the UK government, and is widely used by government agencies within the United States, Australia, New Zealand, Austria and Canada.

The BlackBerry solution is currently used by a wide range of government and public sector workers around the world, including sectors where privacy and security concerns are paramount or mandated such as in the military, law enforcement and healthcare.
