A user's M1 Apple, running Big Sur, was suddenly unable to reach any website starting a couple of days ago. No browser worked; Chrome informed him every time that "Your connection to this site is not secure" and the page timed out. Troubleshooting with Apple, I found that any website could be reached while booted into Safe Mode--i.e., without any third-party software loading at startup. By process of elimination, I found that uninstalling Sophos Endpoint returned full access to all websites.
Endpoint has had a rough start with Big Sur, and it seems the problems aren't over yet. (The latest update is supposed to run natively on M1.) Just thought someone ought to know.
