Types of SSL Certificates
There are different types of SSL certificates: Single-Domain SSL, Wildcard SSL, Multi-Domain SSL, and Unified Communications Certificates. All SSL certificate types have different validation levels, such as Domain Validation, Organization Validation, and Extended Validation. SSL certificates have the same robust encryption strength; the only difference is the validation process by certificate authorities (CA).
DV SSL Certificate
Domain Validation (DV SSL) certificates offer the least verification, simply confirming domain name control. They provide basic encryption and authentication. The Issuance time of DV SSL Certificate is within a minute.
OV SSL Certificate
Organization Validation (OV SSL) certificates validate additional business details such as the business address, phone number, and registration and allow the use of the business name in the certificate details.
EV SSL Certificate
Extended Validation (EV) certificates require extensive verification of business ownership, address, and registration. It establishes the highest level of trust by validating the business’s legitimacy and presence.
Wildcard SSL Certificate
Wildcard SSL certificates provide encryption for an unlimited number of subdomains under a single domain, such as *.example.com. This secures all subdomains like blog.example.com, shop.example.com, and more under one certificate.
Multi-Domain (SAN) SSL Certificate
Multi-domain SSL certificates, also known as SAN certificates, authenticate multiple distinct domains under one SSL certificate. For example, a single multi-domain SSL certificate could cover website.com, store.co.uk, and blog.ca.
Multi-Domain Wildcard SSL
Multi-domain wildcard SSL certificates can protect an unlimited number of subdomains and multiple domains. For example, a single multi-domain wildcard SSL certificate could secure *.website.com, blog.website.com, and blog.co.uk.

SSL Certificate Errors on Firefox
SSL certificate errors on Mozilla Firefox indicate security issues with the encrypted website connection. The most common Firefox SSL errors include “The certificate is not trusted” for unknown certificate authorities, “The certificate has expired” for outdated certificates, and “MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT” for self-signed SSL certificates.
SSL Certificate Errors on IE
SSL certificate errors on Internet Explorer (IE) often occur due to invalid or expired website SSL certificates. Suppose a website’s SSL certificate is invalid, expired, or revoked; in that case, Internet Explorer will display an error message warning users about the certificate issue and allowing them to continue to the website or cancel. Continuing to the site means users will proceed at their own risk as the site may not be secure.
