SSL Certificates

Protect your site visitors' data

What is an SSL certificate?

A Secure Sockets Layer - or SSL - certificate is a web security protocol and essential for protecting your site visitors' sensitive data against fraud and identity theft. SSLs guard data by providing encryption (scrambling of data to prevent tampering during transmission) and validation (verification of the business behind the website). SSL certificates come in different levels of security, depending on the level of protection and security features you need. Often, these features are obvious - Site Seals, HTTPS, and the "green bar" are all visual indicators of a protected site - other times, the security is behind-the-scenes. No matter what level you choose, SSL protection reassures visitors that your site is safe, leading to greater customer trust and increased reliability for your business or brand.

Validation is a key SSL feature. We’ll help you learn about the different levels of validation and how to tell them apart.

Single domain SSLs only allow one unique domain or subdomain to be secured, wildcard SSLs allow multiple subdomains to be secured under one unique domain, and multi-domain SSLs allow multiple unique domains and subdomains to be secured with a single certificate.

Each brand of SSL is known as a Certificate Authority (CA). A CA is an organization that is trusted to sign digital certificates. It also verifies the identity and legitimacy of the company or individual requesting a certificate and, if the verification is successful, issues the signed certificate.
