I don’t understand statements like this. You only need to have some employee install some malware (unintentionally or otherwise); and you have a data breach on your hands.

I agree it's much more scalable to have a vendor install a spyware on all your workstations and have a centralized data breach.

Oh, I wouldn't say that. Viruses are highly scalable.
