San Jose, Calif. – ThreatMetrix, a San Jose-based developer of cybercrime prevention tools, said on Tuesday it has raised $18 million in its fourth round of funding, led by August Capital.

Previous backers Tenaya Capital, US Venture Partners and CM Capital also participated.

Vivek Mehra, general partner with August Capital, has joined the company’s board of directors.
