Mansouri joined OmniTrust Security Systems (formerly Probix, Inc.), a leading provider of IT content security software, as president and CEO in the spring of 2002. The company, founded in 1999, is privately held and backed by prominent venture capital firms and strategic investors such as Walden International, Nomura Research Institute, Mitsui Sumitomo Insurance, Diamond Capital, Lucent Venture Partners, Vertex Management and Global Catalyst Partners. In the fall of 2002 Nomura Research Institute (NRI), one of the largest system integrators in Japan, selected OmniTrust exclusively to offer security solutions. OmniTrust, with its strong blue chip corporate reseller pipeline and patent pending technology, has a two year head-start on its competition in Japan and a growing customer base of Global 2000 corporations. The company is widely regarded as the de facto content security solution in Japan and Korea.

Prior to OmniTrust Security Systems, Mansouri was chairman, president and CEO of iPass Inc. (NASDAQ:IPAS), a premier provider of global remote access services from 1999 to 2001. Mansouri grew the company from $2.8M in revenues in 1998 to over $52 million in 2001. He achieved over twelve quarters of continuous revenue growth, increased gross margin percentages by two times over the same time period and fully funded the company to profitability in early 2001. Mansouri raised a total of $75 million during his tenure at iPass, with $25 million in 1999 and $50 million in 2000 (after pulling the S1 in 2001 due to adverse market conditions). Key investors included Cisco ($20 million), Equant, Comdisco, Rogers Communications, Intel, Sandhill Capital as well three original investors, Crosspoint, Accel, and Asia Pacific Venture Partners. In July of 2003, the company completed one of the most successful IPOs of the year. Mansouri’s strategic direction and market vision were the guiding forces behind the development of iPass’ service initiative with Cisco Systems in 2000, which created the industry’s first global broadband roaming offering in Internet hot spots such as airports, hotels and convention centers. The relationship with Cisco and the broadband network providers was a driving force in the company’s IPO as it uniquely positioned iPass for providing access anywhere, on any device and any network. Under his direction, iPass was also the first to provide secure global remote Internet access from PDAs, and was the industry’s first service provider to offer an integrated VPN and Personal Firewall solution for remote access. During his tenure at iPass, the company moved into a leadership position with over 850 ISP and carrier (85% of the tier 1 global ISPs) customers and over 700 global multinational corporate customers. Mansouri started the Asian, Australian and European operations and increased the staff from 65 to 280 globally. He grew the number of iPass resellers to over 850 worldwide, launched the direct sales channel in the US with over 50 sales staff and repositioned the ISP and carrier channels to complement the reseller channel. Mansouri also tripled the company’s remote access network coverage to 150 countries and 14,000 access points by integrating nearly 180 networks globally including Level 3, UUNet & CompuServe, Genuity, Sprint and Equant. Under his leadership iPass was selected by Computerworld magazine as one of the “Top 100 Emerging Companies to Watch in 2002”. The company was recognized for the significant value it brought to corporate IT as well as for its creative thinking and ability to execute strategy in emerging markets. During the same time iPass was identified as one of “San Francisco’s Top 50 Companies to Watch”.

Prior to joining iPass, Mansouri served as COO of broadband services at Teleglobe Business Solutions, formerly Telco/Teleglobe. At Teleglobe, he defined the company’s data communications strategy and launched Broadband services to the business sector, complementing Teleglobe’s global carrier division as well as its small business and consumer division (Excel Communications).

Before Teleglobe, Mansouri was a corporate officer and vice president of marketing for intermedia Communications/Digex (now MCl/WorldCom) where he was responsible for the development of enhanced data services and played a key role in the acquisition of Digex, which contributed to a significant stock increase ($15 to $75 per share nine months after the acquisition). Later as vice president of market management, he developed the channel strategy for data, Internet, voice and local services. He launched programs to increase product margins, created sales channel efficiencies, and achieved corporate financial objectives for a segment with nearly $60 million in annual revenues.

As executive vice president and general manager for advanced data services at American Communications Services Inc. (ACSI), Mansouri held profit/loss responsibility and led the sales, marketing, promotion, product management, strategic alliances and engineering/operations groups. He was also responsible for directing the development of the industry’s first integrated ATM/FR/Internet service, from concept to commercial launch.

Prior to ACSI, Mansouri held several senior level management positions over a 10-year period in different divisions of Sprint International (now France Telecom/Global One), where he consistently exceeded his revenue and P&L targets, successfully launched marketing and sales programs increasing product margins, formed strategic alliances and developed international business opportunities.

A frequent speaker at key industry events worldwide, Mansouri holds a Bachelor of Science degree in Computer Science and Statistics from Utah State University, a Master of Science degree in Management Sciences from George Washington University (where he graduated Omega Rho) with a minor in Management Information Systems, and has completed the MIT Sloan School of Management program in corporate strategy.
