Certificate Authorities use different authentication methods and levels to verify information provided by organizations. The most basic SSL Certificate only verifies domain name control, a low-level of authentication that may be used by fraudsters to make their sites appear trusted. VeriSign (Symantec), the leading Certificate Authority, secures more than 1 million Web servers worldwide and is well known and trusted because of our rigorous authentication methods and highly reliable infrastructure. VeriSign (Symantec)® SSL Certificates are issued with either full business authentication or Extended Validation (EV) authentication. The VeriSign (Symantec) Trust Seal verification page also includes the status of your daily Web site malware scan and vulnerability scan results (included with Extended Validation or Pro SSL Certificates).
