Google's Plan to Distrust Symantec Certificates

The Google team and the PKI community converged upon a plan to reduce, and ultimately remove, trust in Symantec’s infrastructure in order to uphold users’ security and privacy when browsing the web.



Symantec-owned brands include Thawte, VeriSign, Equifax, GeoTrust, and RapidSSL.


This post outlines how site operators can determine if they’re affected by this deprecation, and if so, what needs to be done and by when. Failure to replace these certificates will result in site breakage in upcoming versions of major browsers, including Chrome.


Information For Site Operators

Starting with Chrome 66, Chrome will remove trust in Symantec-issued certificates issued prior to June 1, 2016. Chrome 66 is currently scheduled to be released to Chrome Beta users on March 15, 2018 and to Chrome Stable users around April 17, 2018.


If you are a site operator with a certificate issued by a Symantec CA prior to June 1, 2016, then prior to the release of Chrome 66, you will need to replace the existing certificate with a new certificate from any Certificate Authority trusted by Chrome.


Additionally, by December 1, 2017, Symantec will transition issuance and operation of publicly-trusted certificates to DigiCert infrastructure, and certificates issued from the old Symantec infrastructure after this date will not be trusted in Chrome.


Around the week of October 23, 2018, Chrome 70 will be released, which will fully remove trust in Symantec’s old infrastructure and all of the certificates it has issued. This will affect any certificate chaining to Symantec roots, except for the small number issued by the independently-operated and audited subordinate CAs previously disclosed to Google.


Site operators that need to obtain certificates from Symantec’s existing root and intermediate certificates may do so from the old infrastructure until December 1, 2017, although these certificates will need to be replaced again prior to Chrome 70. Additionally, certificates issued from Symantec’s infrastructure will have their validity limited to 13 months. Alternatively, site operators may obtain replacement certificates from any other Certificate Authority currently trusted by Chrome, which are unaffected by this distrust or validity period limit.


Reference Timeline

The following is a timeline of relevant dates associated with this plan, which distills the various requirements and milestones into an actionable set of information for site operators. As always, Chrome release dates can vary by a number of days, but upcoming release dates can be tracked here.
