Salim brings to MarkMonitor more than 20 years of experience growing and leading world-class Internet security, fraud prevention, and domain registry companies.

"Threats against a corporation's online brand equity, intellectual property, and revenue streams undermine the integrity of the Internet as a distribution channel," said Salim. "I was attracted to MarkMonitor because it is unique in offering a comprehensive defense against these burgeoning risks by protecting consumer trust and corporate reputation online."

Prior to joining MarkMonitor, Salim was president and chief operating officer of Internet security company Zone Labs, Inc., where he grew the organization from 40 to 230 people and later led its sale to Check Point Technologies in 2004 for nearly $300 million. Before Zone Labs, Salim was president and CEO of NameSecure.com, an Internet domain name registry and services company. Earlier, Salim was president of US and European operations at TrendMicro, which was recognized as a leader in enterprise security under Salim's stewardship.

Other senior executive positions Salim has held include president and CEO at desktop publishing and presentation software company Software Publishing Corporation, and vice president and general manager of the Spreadsheet Division at Lotus Development.

I'm confident that Irfan will continue to drive our focus on creating new and innovative solutions to counter the constantly evolving online threats facing corporations today."
