The story

Commtouch was incorporated as a private company under the laws of the State of Israel on February 10, 1991, by Gideon Mantel, a former officer in a "special bomb-squad unit" for the Israel Defense Forces (IDF). Wired magazine observed that the early company culture at Commtouch encouraged "being a fighter" as their Israeli employees had completed several years of military service.

The Israeli venture capital company Gemini Israel Ventures which was supported by the "Yozma" government program at the time (doubling any investment with government money, see Yitzhak Rabin) made an investment in Commtouch.

In 1997, Isabel Maxwell became president of Commtouch. According to Maxwell, she convinced Microsoft co-founder Bill Gates to make an investment in the business. In 1999, Microsoft co-founder Paul Allen also made an investment in Commtouch of $20-million.

Commtouch went public in 1999.

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, it completed the acquisition of Eleven GmbH, which enabled the company to accelerate the delivery of private-label cloud-based security services, specifically designed for OEM and service provider markets.

In January 2014, it received shareholder approval to change its name from the original of "Commtouch" to Cyren Ltd.

On February 1, 2023, the company announced that, due to "current market conditions and associated challenges with raising additional capital, the Company approved a plan to reduce its workforce by approximately 121 employees, representing substantially all of the Company's workforce." This news followed the appointment in mid-January of Jeffrey Dauer as the company's Chief Financial Officer and Chief Accounting Officer.
