Barracuda Networks was founded in 2003 by CEO
Dean Drako, Michael Perone, and Zach Levow, and the company introduced the Barracuda Spam and Virus Firewall in the same year. In 2007, the company moved its headquarters to
Campbell, California, and opened an office in
Ann Arbor, Michigan. In January 2006, it closed its first outside investment of $40 million from
Sequoia Capital and
Francisco Partners. On January 29, 2008, Barracuda Networks was sued by
Trend Micro over its use of the
open source anti-virus software
Clam AntiVirus, which Trend Micro claimed to be in violation of its patent on 'anti-virus detection on an SMTP or FTP gateway'. In addition to providing samples of
prior art in an effort to render Trend Micro's patent invalid, in July 2008 Barracuda launched a countersuit against Trend Micro claiming Trend Micro violated several antivirus patents Barracuda Networks had acquired from
IBM. In December 2008, the company launched the BRBL (Barracuda Reputation Block List), its proprietary and dynamic list of known spam servers, for free and public use in blocking spam at the gateway. Soon after opening BRBL many IP addresses got blacklisted without apparent reason and without any technical explanation. In 2012, the company became a co-sponsor of the
Garmin-Barracuda UCI ProTour cycling team. Barracuda Networks expanded its research and development facility in Ann Arbor to a 12,500 square foot office building on Depot Street in 2008. By 2012, the Michigan-based research division had grown to about 180 employees, again outgrowing its space. In June 2012, Barracuda signed a lease to occupy the 45,000 square foot office complex previously used as the
Borders headquarters on Maynard St in downtown Ann Arbor. In July 2012,
Dean Drako, Barracuda Networks's co-founder, president and CEO since it was founded in 2003, resigned his operating position, remaining on the company's board of directors. In November 2012, long-time EMC executive William "BJ" Jenkins joined the company as president and CEO. Jenkins worked at EMC since 1998 and previously served as president of EMC's Backup and Recovery Systems (BRS) Division. In November 2013, Barracuda Networks went public on the New York Stock Exchange under the ticker symbol CUDA. In November 2015, Barracuda added a new Next Generation Firewall to its firewall family. In November 2017, private equity firm
Thoma Bravo announced it was taking Barracuda Networks private in a $1.6 billion buyout. In February 2018 Thoma Bravo completed the acquisition. In April 2022,
KKR announced the signing of an agreement to purchase Barracuda Networks from Thoma Bravo for about $4 billion, which was completed in August of that year. In 2025, Barracuda Networks released BarracudeONE, an AI-powered cybersecurity product that consolidates email protection, data backup, threat detection, and extended detection and response. In May 2025, Barracuda Networks appointed Michelle Hodges as Senior Vice President of Global Channels and Alliances. ==Acquisitions==
