Google’s Chrome browser used to display a green padlock in the search bar for secure sites. Why Chrome Displays a “Website Not Secure” Message on Websites One way Google is doing this is by labeling all HTTP websites as “ not secure.” By flagging HTTP sites in this way, visitors receive ample warning to navigate away when visiting unsafe, suspicious, or simply unsecured sites when doing a simple google search. For more than a decade, Google has spearheaded numerous efforts and initiatives, such as the Safe Browsing Project, aimed at making the internet safer for everyone.
