I do have a compliance need, similar to this office i imagine.

Teams is more secure in my opinion.

I as an admin can control who you can/can't talk to, what you can share with them, when you can share it. Correctly configured MS Teams is a pretty secure setup.

On the flipside im not sure i can make someone else's Whatsapp not auto download anything sent to it.... The two apps aren't really comparable unless I've missed an entire 'Whatapps for government/enterprise' business arm.
