That's what we use here, a major financial company. I sit across from mobile support and they constantly get calls and have to tell people rooted phones are not allowed. On Android even some legit apps trigger the phone being rooted.
There is also Mobile Iron.

Sometimes rooted phones are better than unrooted ones.
1. You have more control over the phone.
2. You can install apps that the provider doesn't like (which could be anything).
3. You can set the passwords to anything on the phone.
4. You can remove the excessive crap that the providers put on the phone.
As for "unrooted phones are more secure".. Bullcrap. You should call (or google) HTC and ask them what happened when an exploit nailed some of their popular phones.
