Types of certificates offered at Namecheap

At Namecheap, you can buy SSL certificates provided by Comodo (now Sectigo) Certification Authority. This CA is recognized by 99% of web browsers. This guarantees that browsers will not show security errors when connecting to a site secured by Comodo (now Sectigo).

The certificates can be issued only for Fully Qualified Domain Names (FQDN), also known ascommon names of a certificate.

Example of FQDNs:

  • www.yourdomain.com
  • yourdomain.com
  • webmail.yourdomain.com

For an SSL certificate to function properly, the common name of the certificate must match the URL of the site you are trying to reach. Otherwise, a security alert from the web browser will appear indicating that the name on the certificate does not match the name of the site. If the secure site is reached via https://www.mydomain.com/, but the common name of the SSL certificate is mydomain.com, this will initiate the name mismatch message.

All certificates that Namecheap offers provide up to 256-bit SSL encryption strength that is supported by most of modern browsers (the strength of SSL encryption depends on a browser that the site visitor uses and the web server where the certificate has been installed).

SSL certificates are divided into three groups:

Domain Validation Certificates

  • PositiveSSL
  • PositiveSSL WildCard
  • EssentialSSL
  • EssentialSSL WildCard

Organization Validation Certificates

  • InstantSSL
  • InstantSSL Pro
  • PremiumSSL
  • PremiumSSL WildCard

Certificates with Extended Validation

  • Comodo (now Sectigo) EV SSL
Multi-domain Certificates

    The difference between those certificates is in the way how Certification Authority validates orders prior to issuance. Please review the articles provided at the bottom of the page to find more information about validation for each type of certificate.
