The company's networking and storage products include web filtering, load balancing, application delivery controllers, message archiving, NG firewalls, backup services and data protection.[2]


Barracuda Networks was founded in 2003 by Dean Drako (founding CEO), Michael Perone, and Zach Levow; the company introduced the Barracuda Spam and Virus Firewall in the same year.[3][4][5] In 2007 the company moved its headquarters to Campbell, California,[6] and opened an office in Ann Arbor, Michigan.[7]

On January 29, 2008, Barracuda Networks was sued by Trend Micro over their use of the open source anti-virus software Clam AntiVirus, which Trend Micro claimed to be in violation of their patent on 'anti-virus detection on an SMTP or FTP gateway'.[9] 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.[10]

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.[11] Soon after opening BRBL many IP addresses got blacklisted without apparent reason and without any technical explanation.[12][13][14][15]

Barracuda Networks expanded its research and development facility in Ann Arbor to a 12,500 square foot office building on Depot Street in 2008.[21] 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.[22]

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.[23] At the time of Drako's departure, the company stated it had achieved profitability,[24] a nearly ongoing 30 annual percent growth rate since inception, 150,000 customers worldwide, nearly 1,000 employees, 10 offices, and did business in 80 countries.[25] The company created the office of the CEO as it started a CEO search.[26]

In November 2012, long-time EMC executive William "BJ" Jenkins joined the company as president and CEO.[27] Jenkins worked at EMC since 1998 and most recently served as president of EMC's Backup and Recovery Systems (BRS) Division.[28]
