What is SSL?
Secure Sockets Layer (SSL) is a security protocol for establishing an encrypted link between a server and a client—typically a web server (website) and a browser. Therefore, SSL protects user data during transfer. It is especially important for sensitive information such as credit card numbers, social security numbers, login credentials, and so on.
All browsers have the capability to interact with secured web servers using the SSL protocol. However, the browser and the server need what is called an SSL certificate to be able to establish a secure connection.
Who needs SSL?
Any website owner that needs to securely transmit information over the Internet requires the use of SSL certificates. These days, an SSL certificate is a necessity rather than a luxury. Apart from securing data transfer, an SSL certificate improves customer trust and makes your website rank higher in search results.
