May Netcraft Survey Shows Symantec Has Largest SSL Certificate Gain for the Month and Continues Year-over-Year Market Share Growth

Symantec is the only major Certificate Authority (CA) with year-over-year market share increase for five consecutive months; Sees more than three percent year-over-year growth in each April and May

MOUNTAIN VIEW, Calif. – May 26, 2011 – Symantec Corp. (Nasdaq: SYMC) today announced that it achieved the largest SSL Certificate growth for the month of May with 8,322 units, and its unit market share grew by 3.55 percent year-over-year, according to the latest Netcraft survey. The Netcraft Secure Server Survey for May 2011 reports that all SSL Certificate brands under Symantec-- including VeriSign, Thawte, GeoTrust and RapidSSL-- make up 41.72 percent of the SSL market, which is 31 percent more than the nearest competitor.

In addition, Symantec witnessed a 3.1 percent year-over-year unit growth in the month of April as well as a steady uptick in the previous five months while all other major Certificate Authorities* experienced a loss in unit market share for the same period.


“We attribute our undisputed market leadership for the past 15 years to the fact that customers recognize that we offer the most comprehensive product lineup and highest quality technical support,” said Fran Rosch, vice president of Trust Services at Symantec. “We have continued to innovate beyond traditional SSL services to provide value-added trust services, most recently with Seal-in-Search and web site malware scanning for the VeriSign brand.”


This month’s report comes amid a series of high-profile attacks on consumer-facing websites due to insufficient application of SSL technology. Concerns over rogue hotspots and related man-in-the-middle (MITM) attacks have highlighted the importance of extending SSL use to protect web sessions beyond login and transactional pages to the entire user session. As a result, many leading web sites have lead the charge to ensure a higher level of consumer protection by adopting more complete SSL encryption on their sites.


The Netcraft May 2011 report found a total of 1,722,572 distinct valid third-party SSL Certificates, of which 718,683 certificates are provided by Symantec and its brands. The report noted that Symantec maintains its lead in the extended validation and organizationally validated markets with shares of 68.7 percent and 43.8 percent, respectively.


Symantec continues its strong position in the market by offering customers more value-added services than the competition. VeriSign® SSL Certificates enable customers to receive daily malware scans and Seal-in-Search™, which allow the VeriSign seal to be displayed within search engine results to boost traffic to web sites. Also under the Symantec umbrella are the GeoTrust, Thawte and RapidSSL brands, which have experienced strong growth as well.


* “Major Certificate Authorities” include CAs with five percent market share or more.
