# Barracuda Networks

Barracuda Networks, Inc. provides security, networking and storage products based on network appliances and cloud services.

## History

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 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'. 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. At the time of Drako's departure, the company stated it had achieved profitability, 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. The company created the office of the CEO as it started a CEO search.
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 they were taking Barracuda Networks private in a $1.6 billion buyout. In February 2018 Thoma Bravo announced that it had 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.

## Controversies
### Security Issue

In January 2013, a backdoor was discovered: "A variety of firewall, VPN, and spam filtering gear sold by Barracuda Networks contains undocumented backdoor accounts that allow people to remotely log in and access sensitive information, researchers with an Austrian security firm have warned." The backdoor was then secured shortly after the announcement.

### IP reputation and Emailreg.org

On April 13, 2009, Emailreg.org published a notice clarifying that it is a whitelist of domains that had no impact on Barracuda Blog Lists. April 10, 2010, a blog entry appeared alleging that Barracuda Networks SPAM blocking deliberately targets non-spamming IP addresses and tries to get them to sign up for an email whitelisting service "emailreg.org". In 2019 Emailreg.org announced that it was no longer accepting new customers but would continue services for existing customers until further notice. Emailreg.org discontinued services shortly thereafter and is no longer in operation. As of May 2, 2020, the same warning appears for some IP addresses.
