Barracuda Networks, a network security provider, has filed for an initial public offering of up to $100 million, according to SEC documents filed on Tuesday.

You might know Barracuda Networks from those ubiquitous airport billboard ads. The company, founded in 2002, sells network appliances to enterprises for security and data services, and then it also sells subscription and cloud services once the appliances are connected. The company is known for a “high-velocity” sales model which allows any customer a 30-day right of return. It most recently had about 1,000 employees.

The lead underwriters will be Morgan Stanley, J.P. Morgan, and Bank of America Merrill Lynch. The company plans listing under the ticker “CUDA.”

The Campbell, Calif.-based firm underwent a major re-organization and re-capitalization in the fall of 2012, when it tapped $130 million in funding from Sequoia Capital and Francisco Partners and paid out earlier investors. Shortly thereafter, current CEO William Jenkins, a former EMC executive, became the CEO, replacing CEO and founder Dean Drako.

The company reported gross billings of $233.2 million in 2012 and $264.2 million in fiscal 2013. For the first six-months of this year its gross bookings were $150.5 million. The company posted $41.1 million in adjusted free cash flow last year, but it incurred a net loss of $8 million in 2012 and $4.4 million through the first six months of this year.

Gross billings grew 22% from 2011 to 2012 and adjusted cash EBITDA grew 34% from 2011 to 2012.

The company likes to use the gross billings number, which it describes in the filing as total revenue plus the change in deferred revenue and other adjustments, including product returns and rebates from sales channels.

“We use gross billings as a performance measurement and a leading indicator of our future revenue, based on our business model of invoicing our customers at the time of sale of our solutions and recognizing revenue ratably over subsequent periods,” says the company in the filing.

The company has a number of connected people involved. Well-known networking executive Gordon Stitt is on the board. On Sept. 19, Kevin Thompson, SolarWinds (SWI) President and CEO, joined the board.
