Company history

Cyren was incorporated as a private company under the laws of the State of Israel on February 10, 1991. In September 2010, the company acquired the Command Antivirus division of Authentium, and in October 2012, completed the acquisition of the antivirus business FRISK Software International. In November 2012, the company completed acquisition of Eleven GmbH, which enabled the company to accelerate delivery of private label cloud-based security solutions, specifically designed for OEM and service provider markets. In January 2014, the company received shareholder approval to change its name from the original of “Commtouch” to Cyren Ltd.
