Replace Your Symantec SSL/TLS Certificates
Check your website for Chrome distrust
Upcoming releases of Google Chrome in March and September 2018 will no longer trust certain Symantec, Thawte, GeoTrust, and RapidSSL SSL/TLS certificates. Chrome users will see “Not secure” in the address bar when connecting to websites using a distrusted certificate.
Near the end of July 2017, Google Chrome created a plan to first reduce and then remove trust (by showing security warnings in the Chrome browser) of all Symantec, Thawte, GeoTrust, and RapidSSL-issued SSL/TLS certificates. Google broke this timeline up into 3 important dates. December 1, 2017, March 15, 2018, and September 13, 2018. The first date, December 1, 2017, required no action from you. However, for the 2018 dates, you must replace affected certificates to avoid Google Chrome browser security warnings. Read our blog post for details on these dates and the Chrome timeline.
