Certificate Transparency Policy Analyzer

By SSLMate

On May 1, 2022, Google Chrome rolled out a change that caused some SSL certificates issued in 2020 to stop working, resulting in a NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED error when you try to visit the website in Chrome.

On May 3, 2022, Chrome temporarily reverted this change but still plans to go ahead with the change in the near future, and recommends that sites using impacted certificates replace those certificates as soon as possible.

You can use this tool to check if your website is affected. If the tool reports that your website's certificate is non-compliant, contact your certificate authority as soon as possible to get a new, compliant certificate.
