The GlobalSign ExtendedSSL certificate is high-end with Extended Validation. In other words: an extended validation of your enterprise according to the highest industry standards. Visitors of a GlobalSign ExtendedSSL enabled site will see a full green address bar in the browser including the name of your organisation. Extra SANs can be added at minimal cost.
Green address bar set aside, the Secure Site with EV SSL certificate offers daily malware scans of your website, the highly recognizable Norton Secured Seal, and Site-in-Search, which displays your seal in search results.
The Rolls-Royce of certificates: green address bar and minimum encryption of 128 bits, of course, but the whole Symantec add-on package too: Site-in-Search, the prized Norton Secured Seal, and daily malware scanning of your website.
GeoTrust's TrueBusinessID EV offers the highest level of validation and trust at the lowest price. Visitors to your website get to see the coveted green address bar with your company name, leading to increased trust and higher sales. Your best choice for a low-cost EV certificate.
