Stewart Grierson Named CFO of the Year

ArcSight, Inc. (NASDAQ: ARST), a leading global provider of security and compliance management solutions that protect enterprises and government agencies, today announced that CFO Stewart Grierson has been named CFO of the Year in the Public Company category by the Silicon Valley/San Jose Business Journal. The CFO of the Year Award winners were announced at an awards dinner on November 19 at the Computer History Museum in Mountain View, California.

The awards honor CFOs in five categories, describing the winners as “the financial superheroes of business that are a force in Silicon Valley.” Award recipients are selected annually by a panel of executive judges made up of leaders in Silicon Valley businesses. According to the Silicon Valley/San Jose Business Journal, “This year’s CFO of the Year award winners and runners-up demonstrate the diversity of industry backgrounds and experience levels that have helped Silicon Valley’s companies weather the worst economic trough since the Great Depression.”

Stewart Grierson has been instrumental in the success of ArcSight, leading the company through its public offering last year in one of the most challenging economic times in recent history. ArcSight was the only venture-backed, Silicon Valley-based IPO in 2008. Grierson joined ArcSight in 2003 and has served as Chief Financial Officer since October 2004. Silicon Valley/San Jose Business Journal profiles Grierson as Public Company CFO Winner in the November 20 issue article titled, “Grierson helped lead ArcSight, valley's only IPO of 2008.”

“Stewart embodies what it takes to be an excellent CFO,” said Stan McKee, ArcSight board member and chairman of its audit committee, and former CFO of Electronic Arts. “In addition to knowing the numbers and having good technical knowledge in finance, he is a good communicator, has a detailed grasp of the business and is a valuable contributor to the strategic direction of the company. As a CFO, it’s easy to get lost in the numbers and forget that what we’re doing affects the lives of every employee and stockholder. Stewart always has that top of mind.”

“I have been very fortunate to have Stewart as one of our key executive team members helping to successfully grow our business during one of the most difficult economic environments in decades,” said Tom Reilly, ArcSight President and CEO. “Our ability to grow in the past year and to deliver solid operating margins is a testament to the strong operational decisions that Stewart makes on a day-today basis. His contribution goes well beyond the CFO role as his opinion is valued across the business.”

ArcSight and its products continue to gain the respect of the industry. Already in 2009, ArcSight ESM / Logger received the gold in the SIEM category in the Information Security™ Magazine and Searchsecurity.com™ 2009 Readers’ Choice Awards and ArcSight ESM won the First Annual Homeland Security Awards from Government Security News (GSN) in the Best Security Incident and Event Management category. ArcSight was also named one of the ‘Best Places to Work’ in the Bay Area by the Silicon Valley/San Jose Business Journal and the San Francisco Business Times. In addition, ArcSight’s partner program was awarded a Five-Star Partner Program certification in Everything Channel's 15th annual 2009 Partner Program Guide.
