In its efforts to achieve a secure global web, Google has set itself the goal of alerting its users about insecure sites, as well as giving greater visibility to websites with this type of certificate. Let\'s Encrypt is a free, automatic, and open certificate authority. It is a method through which we can encrypt the information transmitted on different websites. The information we normally send when making an electronic transaction, when filling out contact forms, or simply registering as users. In any action where we enter information on a website, we send information from the browser to a server. With an SSL certificate installed, this information is automatically encrypted, making it unreadable to eavesdroppers or interceptors. How to install a Let\'s Encrypt SSL certificate. Installing it for free on your servers is easy and secure. Simply log in to cPanel, access the Let\'s Encrypt SSL module, and install it on the appropriate domain. Afterward, you\'ll need to modify your website to permanently redirect traffic from HTTP to HTTPS.
