An SSL (Secure Sockets Layer) Certificate is a layer of security that authenticates the identity of your website and helps encrypt information sent between your browser and the domain’s server. Without encryption, any computer between yours and the server would be able to see all kinds of sensitive information, such as usernames, passwords, and credit card numbers.
The encryption enabled by SSL Certificates is very important. If your users fill out forms on your website, an SSL Certificate protects your users’ information from being stolen. If your websites have a login feature, an SSL Certificate’s encryption will protect the user’s login information. If you sell anything on your website and accept credit card payments online, an SSL Certificate’s encryption will guard this vital information as well.
Having an SSL Certificate also adds a level of trust for your users by showing them your dedication to security against hacks and phishing. If you have a basic website without any eCommerce or login features, you may not need an SSL Certificate. However, if you require logins or send/receive private customer data (such as credit card information), you definitely need an SSL Certificate.
