"Our first-half 1999 financial results clearly show the increasing success of our Internet ‘VirusWall’ strategy," said Steve Chang, chairman and chief executive officer of Trend Micro. "With record sales growth in both the United States and Europe, and strategic partnerships with Internet service providers (ISPs), we will strive to continue to provide our customers with breakthrough Internet-based technology and to further develop our recurring-revenue business model."

Trend Micro also expanded, during the period, its global presence by forming alliances with several multinational companies. An agreement with Lucent Technologies signed in March, 1999 was followed by the introduction of InterScan ® VirusWall® with eManager™ which is integrated with the Lucent Managed Firewall and VPN Gateway to provide integrated Internet content filtering. This product was specifically designed to meet the needs of networked enterprise and Internet service provider (ISP) environments. In April 1999, the Company also announced a strategic partnership with Compaq Computer Corporation to deliver Trend's server-based antivirus solutions through its Compaq ActiveAnswers Program, an online resource for marketing, buying and deploying business and enterprise solutions.
