SSL
SSL certificates make online interactions private even though they travel through the public Internet, and they help customers gain the confidence to transact and share information with your web site. If you ask users of your web site to sign in, if they enter personal data such as contact and residential information or possibly even credit card details, or if they view confidential information such as health benefits or financial accounts, you need to keep that data private and secure. You also need to help them confirm that your web site is authentic and safe. SSL is also used for email servers, web-based applications, server-to-server communications and more.
