You obtuse "whatever that is" sure made it sound like you did.

That is the kind of stuff you can only say if you're not concerned about anyone but yourself.

I have employees that need to send emails, do calls with customers, work on digital documents, and collaborate efficiently. If they drop their laptop, or it gets stolen, I don't want these documents to get lost, or compromised. I need them to sign in to a myriad of services securely, using a single identity that I can centrally block if their account is compromised or the contract terminated.

All of that isn't what some "marketing boy" wants me to believe, but hard requirements to do business, and protect the privacy of our employees and our customers.
