ThreatMetrix, the fastest-growing provider of integrated cybercrime prevention solutions, announced today that it has closed a Series D round of financing. August Capital led the investment round of $18 million in capital, with existing investors Tenaya Capital, US Venture Partners and CM Capital also fully participating in the investment.

"The previously separate worlds of fraud and security are converging and ThreatMetrix is ideally situated to help companies and government entities reduce fraud losses while preventing data breaches from stolen identities," said Vivek Mehra, general partner, August Capital. "Our confidence in ThreatMetrix is demonstrated by their impressive track record of rapid customer adoption, new market expansion and global growth. With today's financing announcement, we hope to further accelerate that growth."

As part of the financing round, Mehra joins the ThreatMetrix board of directors. The partners of August Capital have invested in leading companies such as Atheros, Microsoft, Postini, Sun, Symantec, Seagate, Skype and Splunk.

"We're extremely pleased to have August Capital, one of the preeminent Silicon Valley venture capital firms, lead this round," said Reed Taussig, president and CEO, ThreatMetrix. "ThreatMetrix is expanding on all fronts including new products, applications, markets and geographies. Our recent TrustDefender acquisition has provided ThreatMetrix with the only integrated solution combining intelligent device identification with malware man-in-the-browser (MitB) detection and remediation available in the market today. This combination of products has positioned ThreatMetrix as the leader for device centric fraud prevention and as a competitive vendor for the evolving market of remote employee authentication popularly referred to as 'bring your own device' (BYOD)."

According to Taussig, the company will use the additional funding to continue its successful global expansion into e-commerce, financial services and the enterprise remote employee access markets.
