What does “This Site Is Not Secure” mean?

When you follow one of our links, your web browser may occasionally display a warning saying “This Site Is Not

Secure”. Please do not be alarmed. This warning does not necessarily mean that the website is dangerous, fraudulent

or infected with a virus.

Usually, it simply means that the website is an older site which does not use the modern HTTPS security system. If you

are only looking at information, photographs or historical material, this does not necessarily prevent you from using

the site.

However, we recommend that you do not enter passwords, credit-card details or other private information into a

website displaying this warning.

If a warning says “Your connection is not private”, this is different and may indicate a problem with the website's

security certificate. In that situation, it is best not to proceed until the problem has been checked.

In short, “Not Secure” does not automatically mean “unsafe”. It is primarily your browser telling you that the

connection to an older website is not protected in the same way as modern websites.
