Check your website if you use Symantec SSL Certificates

Reported last year, the decision was taken by Google to stop trusting some Symantec SSL Certificates on servers. This decision was taken after a number of failings in the authorisation chain of Symantec Certificates. Back in 2017 there was a public posting questioning the authentication of a number of Symantec Corporation PKI certificates. It appeared that a number of certificates issued did not conform to correct baseline requirements, and Symantec had authorised other organisations to issue certificates on their behalf without appropriate oversight.

The Google Chrome browser which is used by the majority of users when surfing the web will stop trusting these certificates when the update is released on April 17, 2018.
