Why EV SSL certificates are better than OV Certificates

Organization validation certificates (OV) verify domain ownership and a company's existence. With that in mind, why would major online businesses prefer Extended Validation certificates (EV) to OV certificates?

First off, EV certificates require thorough verification checks that confirm an organization’s long-term legal and physical existence. These conditions make EV certificates a guarantee of a site’s security and reliability.

EV certificates ensure

  • The company name or DBA (doing business as) is exactly the same in corporate documents and on the website;
  • The Certificate Authority has verified the legal documents of the company (a partial third-party audit);
  • The company exists and operates in fact.


EV certificates provide exclusive website indicators that reassure customers and other site visitors. Only EV certificates display green bar verification in the browser address bar. The green bar is easily visible even for the least-experienced users, encouraging trust and confidence.

Another advantage of EV certificates is the Corner of Trust, unavailable for OV certificates. This dynamic Site Seal displays Company information, such as domain name, company name, address, city, state and country, and appears in the corner of the screen regardless of your location on the page.



EV Certificate Authorities provide highest warranties of up to $1,500,000 comparing to the average OV certificate warranty of $250,000.
