London, UK – 28th April 2008 – ArcSight, Inc. (NASDAQ: ARST), a leading global provider of compliance and security management solutions that protect enterprises and government agencies, today announced its inaugural channel partnership deal in Sweden with reseller Heimore Group.  The deal confirms Heimore as a fully accredited and supported reseller in Sweden for the entire range of ArcSight enterprise compliance and security management solutions, including ArcSight ESM and ArcSight Logger.

“We evaluated the market for log audit products for 18 months as part of a wider project for one of our customers and concluded that ArcSight has the leading log management and compliance solution available.  Furthermore, it became apparent during the process that the full range of ArcSight compliance and security solutions would significantly benefit our customer base,” said Tomas Persson, Partner Alliance Manager at Heimore Group.  “The Swedish market for log management solutions in particular is relatively immature, but we are experiencing an increased demand from our customers for such products.  By teaming up with ArcSight, we will help this market mature, enabling us to lead the way and enabling our customers to have access to a comprehensive solution.”

Iain Chidgey, managing director, EMEA, ArcSight, said, “Heimore is an excellent addition to our expanding EMEA partner network.  We believe that their understanding of the Swedish market will enable us to gain a firm foothold in this region with a partner that is very well established and very technically competent.  We have a growing presence in Scandinavia, and this deal further strengthens our credentials.  Since Heimore is a fully accredited and supported reseller, under the agreement, Heimore’s customers will receive the ArcSight market-leading solutions with excellent support and service from implementation throughout the lifecycle of each solution.”
