Mountain View, Calif., Dec 16, 2005, AirTight Networks™, the leader in wireless perimeter security, today announced that it has closed a Series B financing totaling $12 million. This raises the total amount of capital invested in the business to $22.25m.

The investment was led by Trident Capital, one of AirTight’s Series A investors. John Moragne, Managing Director of Trident Capital, has joined the company’s Board of Directors. All of AirTight’s Series A investors (Walden International, Granite Ventures, Blueprint Ventures, as well as Trident) joined in the company’s Series B financing round. Siemens Venture Capital, the venture capital arm of global conglomerate Siemens AG, also participated in AirTight’s latest financing as a new investor.

“AirTight is on the rapid growth ramp that characterizes successful start-up companies,” said David C. King, Chairman and CEO of AirTight Networks. “We’re gratified that AirTight’s previous investors have shown confidence in our execution to date as well as our future potential. We are also pleased that Siemens Venture Capital has chosen to participate in this latest funding round.”

“Trident Capital has a strong focus on security technology, and we’re excited about AirTight’s tremendous potential as a market leader in a rapidly emerging space,” said John Moragne, Managing Director, Trident Capital. “Over 97% of all enterprises have wired perimeter security solutions today, but less than 2% have the equivalent wireless perimeter security functionality.
