We still have some LOB apps which require IE and some horribly unsafe settings to make it work. We’ve now got some settings which switch them to Edge for other pages which are not on a list which mitigated part of the issue but if any of those legacy apps which haven’t been improved in 15+ years get compromised (which lets be honest would probably not be hard) then bye bye org. I really hope we’re not going to see ActiveX mk2, one of those things that sounds great in a developers head at the time and is sold to the marketing team.
