According to the University of Wisconsin-Madison, there are two ways to know if the website you’re about to visit is considered secure: HTTPS and a padlock icon. Look at the website’s URL and check for the letter S. A secure website URL will start with HTTPS, with an emphasis on the letter S as this indicates that the website is using an SSL certificate. You may find website URLs that start with HTTP, without the S — in general, these are no longer regarded as secure.
