What is a Standard SSL Certificate?
A single-domain SSL (Secure Sockets Layer) certificate:
- Establishes a secure connection between a browser and a server
- Encrypts communication—reassuring visitors their sensitive information, such as credit card information, is safe
- Authenticates an organization’s identity
- Places a padlock next to your web address in the browser
