What is an SSL certificate?
An SSL certificate is a form of validation that is installed on the web server.
SSL/TLS is a technology that creates an encrypted connection between the web server and your visitor’s web browser so that confidential information can be transferred securely.
Your secure site is now accessed via https rather than http, and indicated by a padlock icon in web browsers. A site’s SSL certificate can be viewed by clicking or hovering on the padlock icon in the address bar. Digital certificates are issued directly by a trusted certificate issuing authority like Thawte, Comodo, Let’s Encrypt.
SSL/TLS certificates – which one is right for you?
All SSL certificates offer the same levels of encryption but differ according to validation levels – the extent to which the domain is vetted and proven to be linked to a particular organisation. The validation level does not affect the security level but rather reflects levels of user trust i.e. the more you need users to trust your website’s authenticity, the higher level of validation certificate you will choose.
