SSL: Protection against data interception

This ensures the privacy and security of your data as it travels over the network.

Trust verification tool

SSL certificates also perform a trust verification function. When a user visits a website, the browser checks whether the website has an SSL certificate. If the certificate exists and is valid, the browser marks the site as “secure”, usually with a lock icon or “https://” in front of the URL. This gives users confidence that they are interacting with a legitimate site and not with malicious actors who may be trying to spoof the site.

Types of SSL certificates

There are different types of SSL certificates, including:

Single Domain: This certificate covers only one specific domain or subdomain. For example, “www.example.com”.

Extended Validation: This type of certificate provides more trust, as it requires more rigorous verification of the domain owner or company. It is marked with a green underline in the browser.

Multi-Domain: This certificate allows you to protect several domains at the same time.
