Google has stated its intent to take the following steps relating to the Chrome browser with respect to Symantec certificates:
- Reduce the maximum accepted validity period of newly-issued Symantec certificates to 9 months or less
- Implement a gradual distrust in Chrome browser of all current Symantec-issued certificates, requiring the certificates to be replaced with new certificates before the original would expire
- Removal of recognition of the EV (Extended Validation) status of Symantec EV certificates for at least one year
Symantec's response to the proposal and a public discussion may be found here.
Since Google Chrome has a majority of the browser market, its proposed deprecation of Symantec certificates, including GeoTrust and Thawte, in the Chrome browser may potentially affect Chrome user traffic on your web sites.
