Ask HN: Do Companies Tie Digital and Physical Security Together?

This is a question for those with industry experience out there.

I imagine that major companies today are concerned about their computer security. From my understanding, it is not unrealistic for a company to higher a contractor to audit and/or overhaul existing security. What I am curious about is if companies worry about the physical security of their data as well. Do they rely on their computer security guys to give them advice? I would think that the people who would be most aware of the physical security needed to complement whatever computer security exists would be the people responsible the digital security measures. Or are these two aspects of security usually handled by two different entities?
