NET::ERR_CERT_SYMANTEC_LEGACY Google Chrome warning

What should you do when you see this warning message in your web browser, i.e. Google Chrome?

1. Don’t panic. You didn’t do anything wrong, per se. Take a deep breath. Ahhh.
2. This error means the website is using an SSL certificate that is obsolete. (You can read more technical details if you want.)
3. You could go ahead and click on the “Advanced” button on the lower left corner to proceed to the site. However, avoid entering any personal information while visiting the site, since the site is unverified and insecure.
4. If you want to be a “Good Samaritan,” you can contact the webmaster of that site, and mention that their SSL certificate needs to be renewed and upgraded. Share the link to this blog post.

What if you’re the webmaster or site administrator?

Symantec and DigiCert will replace all affected certificates at no cost. Learn more about how to do this at symantec.com.
