SAN FRANCISCO, CA–( EMWNews – April 8, 2008) – RSA CONFERENCE — VeriSign, Inc. (NASDAQ: VRSN), the trusted provider of Internet infrastructure services for the

networked world, has helped the world’s first online distributor of digital

sheet music achieve a 31 percent increase in sales and a 67 percent boost

in membership renewals. In a separate test to determine the effectiveness

of the deployment of Extended Validation (EV) Secure Sockets Layer (SSL)

Certificates from VeriSign, Virtual Sheet Music saw users on EV-enabled

browsers complete 13% more transactions, which yielded a staggering 7,440

percent return on its investment in the VeriSign solutions.

Every day, Virtual Sheet Music, Inc. (www.virtualsheetmusic.com) serves

more than 20,000 musicians and educators seeking high-quality sheet music

for classical works. The company also offers exclusive custom arrangements

and music transcriptions for any instrument.

Always committed to addressing the security concerns of its customers,

Virtual Sheet Music deployed the VeriSign Secured® Seal in 2006 after

suffering a slowdown in sales after posting a competitor’s seal.

“We’re a small company that’s not very well known to a lot of people, and

users are often reluctant to provide their credit card numbers over the

Internet to a source they don’t know and trust,” said Fabrizio Ferrari,

president and founder of Virtual Sheet Music, Inc. “They need confidence

that we have the required technology in place to deliver what they paid for

in a secure manner, which VeriSign helps us provide.”

After implementing the VeriSign Secured Seal, the company immediately

recognized a 31 percent increase in sales and a 67 percent jump in

membership renewals.

To further build customer confidence and trust, Ferrari and his team also

deployed VeriSign Extended Validation (EV) Secure Sockets Layer (SSL)

Certificates. VeriSign® EV SSL provides an effective weapon against

phishing scams that lure unsuspecting consumers to imposter sites that

appear almost identical to genuine Web pages. Identity thieves use these

fraudulent pages to capture credit card numbers and other valuable personal

information.

When a Web site uses an EV SSL Certificate to identify itself, certain

browsers including Internet Explorer 7 (IE7) and the latest beta version of

Firefox 3 display easily understood visual cues to provide tangible

assurance of a site’s authenticity. The address bar turns green, a lock

icon appears next to the address, and a new field appears to the right of

the URL in the browser. This field contains the name of the organization

that owns the site as well as the security provider that issued the

certificate, such as VeriSign.

To measure the benefit of implementing VeriSign EV SSL authentication,

Virtual Sheet Music examined sales to customers who use IE7 and therefore

see the address bar turn green when they commence a purchase and compared

them with sales to customers whose browsers lacked that capability. “The

IE7 users bought 13 percent more,” said Ferrari. “This proved that there is

still fear of having a credit card number stolen among our client base, and

that the green bar provided the extra measure of confidence needed to

overcome it.”

For Virtual Sheet Music, the investment in VeriSign Secured Seal and

VeriSign EV SSL solutions has paid off handsomely. Based on measured

incremental sales, the company reports an ROI of 7,440 percent. To read

“VeriSign is the leader, the best known name in transaction security and

Web site authenticity,” added Ferrari. “I don’t know why everyone doesn’t

use VeriSign.”
