FaceTime Communications, a Foster City, Calif. provider of software that provides security control over communications within businesses, said it has raised $15.6 million in financing.

Here’s the statement,

The investment was led by the Credit Suisse NEXT II Fund, and included existing investors Sutter Hill Ventures, JK&B Capital and Scale Venture Partners.

The company’s product offers control over things like peer-to-peer, instant messaging and voice-over Internet protocol applications. Research firm IDC named FaceTime the market share leader among instant messaging management vendors for the fourth consecutive year, the company said.

A snippet from the statement:

FaceTime will use this investment to expand and accelerate its market strategy. As a first step in its market expansion, the company today also announced its Unified Security Gateway (USG). From a single platform, USG integrates management, security and compliance of Web usage; greynet applications such as public IM, Skype and P2P; and enterprise-class unified communication platforms such as Microsoft’s Office Communications Server and IBM Lotus Sametime.

The company says about 1,000 customers paying on the order of $100,000, with the company’s chief executive Kailash Ambwani telling Dow Jones (subscription required) that the company will be profitable in nine months and could go public in 12 to 18 months. The company has raised about $50 million since it restarted in 2001 with a different model. Previously, investors had pumped in about $40 million.
