Light or dark mode
You can switch between viewing modes for Sophos Central.
Your choice of viewing mode is kept in Sophos Central, Sophos Cloud Optix, and Sophos Mobile. This means that if you turn on dark mode in Sophos Central and go to Sophos Cloud Optix that will also show in dark mode.
Viewing mode isn't supported in Firewall Management. Firewall Management pages are always shown in light mode.
