Reflex Security, the three-year-old startup focused on intrusion prevention and detection systems for networks, has a new chief executive officer and new investors.

James Watson, a former executive at research firm Gartner Group, takes over as chief executive officer. He also is among the new investors who poured an unspecified amount of money into the venture.

Watson spent 11 years at Gartner, managing the firm’s Canadian operations at one time and was part of the management team that took the company public. He later joined RedCelsius as chairman and CEO.

“While representing a prominent private investment group, I looked for the next-generation security software company that had a proven and mature product with referenceable customers and was in the need of capitalization,” Watson said in a statement. “The investors and I feel strongly that we have found that company in Reflex Security.”

The company was founded by Hezi Mualem and Carson Spencer in 2000 as Trellis Network Security. It closed on $1 million in angel funding in September of 2000 and signed a $1 million contract with a South Korean firm in May of last year. The company’s name was changed to Reflex Security in 2002 at about the same time Trevor Horowitz was named CEO.

Mualem remains at Reflex Security as its chief technical officer.
