VeriSign (VRSN)

Internet Services Group (ISG)

2007 compared to 2006:    Revenues from our ISG increased by approximately $158.2 million. Our Naming Services revenues increased $91.9 million due to a 24% increase in the number of active domain names ending in .com and .net under management. The growth in .com and .net domain names was driven by continued global Internet adoption and strong renewal rates of existing domains. Our Information and Security Services revenues increased $55.7 million primarily due to a $43.9 million increase in SSL Certificate services revenues that was the result of a 16% increase in the installed base of SSL certificates and recognizing a full year of revenues from the GeoTrust acquisition in late 2006. Additional increases in our Information and Security Services revenues were primarily due to increases in our VeriSign Identity Protection services and our United Authentication services that was the result of an increase in demand for secure real-time validation capabilities.

2006 compared to 2005:    Revenues from our ISG increased by approximately $125.0 million. Our Naming Services revenues increased $69.4 million due to a 30% increase in the number of active domain names ending in .com and .net under management. Our Information and Security Services revenues increased $55.6 million primarily due to a $29.3 million increase in SSL certificate revenues that was the result of a 65% increase in the installed base of SSL certificates, an $11.9 million increase in our managed security services and security consulting revenues, and a $14.4 million increase in other information services revenues. The 65% increase in the installed base of SSL certificates was primarily due to the 259,000 additional certificates acquired as a result of the acquisition of GeoTrust in September of 2006. Excluding the GeoTrust transaction, the installed base of SSL certificates would have increased 12% year-over-year.
