The security panel displays connection information for every network request, demystifying what connection errors keep you away from the green lock that represents a secure connection. Glancing at the overview for a given page, you can find information about:





Certificate verification , indicating whether your site has proven its identity with a TLS certificate.

TLS connection, indicating whether your site uses a modern, secure protocol and ciphersuite .

Subresource security, indicating whether your site loads insecure HTTP subresources (otherwise known as mixed content ).





In addition to debugging an insecure TLS connection, you can also easily check the state of your subresources. Clicking on a subresource gives you in-depth information about the security state of a given connection, as well as details about its certificate.









For more details about the new security panel, check out our post on the Google developer blog . If you’re new to TLS, you can get started with our developer resources on Web Fundamentals.





Stay tuned for more features coming to Chrome, helping you get to the green lock and beyond !
