Distrust Symantec Certificates issue

Hello Everyone,

As you all might be aware of, Google, Apple, Microsoft, and Firefox announced to distrust Symantec vendor issued certificates to uphold user’s security and privacy when browsing the web. Currently endpoints which are still on Symantec certificates will no longer work once Browser and OS vendors rollout update as early as fall 2018. 
How this would impacted any organization and also how we can mitigate this issue. 
Also will it impact accessing SEPM console via web browser and also will  SEPM and SEP client communication get impacted. Please let us know.

Thanks,

Sundeep
