Chrome, Firefox to Block Sites Using Symantec Certificates in October
Chrome and Firefox will be blocking user access to websites still using Symantec/DigiCert TLS certificates sometime this October when the latest version of the browsers will be released.
Website owners still using Symantec, Thawte, GeoTrust and RapidSSL SSL/TLS certificates are urged to update immediately. DigiCert users can have theirs replaced for free and there are also other replacement options such as Comodo, Entrust, or Network Solutions.
However, those seeking a replacement Google Chrome SSL/TLS certificate must have all their domains revalidated and re-authenticates for Domain Validation (DV), Organization Validation (OV), or Extended Validation (EV) SSL Certificates.
