Google Chrome uses visual indicators to inform users about a site's security status :
- Padlock Icon: The site has a valid SSL, and the connection is encrypted.
- "Not Secure" (Grey): The site lacks an SSL certificate or is using an expired one.
- "Not Secure" (Red Triangle): The certificate is invalid, revoked, or has a severe configuration error.
- Info 'i' Circle: This often indicates Mixed Content, meaning the site has an SSL but some elements are loading over an insecure connection .
