Under page no -5 its mentioned that
Note that IE11 is not a supported browser.
Can you explain is it CB console not supported or IE11 not supported
for systems having CB sensor installed.
I have IE11 with CB installed and both are working fine
IE11 is not an officially supported browser from the perspective of browsing the Cb Defense Admin Console.
The Cb Defense sensor and the IE11 browser should not have any compatibility issues.
