Silver Tail Systems, a provider of predictive analytics for detection and prevention of online fraud, this morning announced that it has secured an additional round of funding from Citi Ventures, a unit of Citigroup.

This investment, the size of which was not disclosed, is part of a previously announced $20 million Series B funding round led by Andreessen Horowitz (closed in June).

Silver Tail Systems provides on-premise and SaaS solutions to protect operators of online properties that hold critical information, such as e-commerce, financial, government and consumer-facing website publishers and owners, from online fraud and abuse.

The company says it currently monitors more than 750 million users and more than 1.8 billion Web sessions per year.
