Think about what VPN is. It's simply a way to cheaply and securely
connect remote sites. That's it. Once you're connected, you're
basically on the LAN. So any infection, viruses, etc. can be
transmitted just as easily (unless you've got a VLAN with further
firewalling between the two).

So, yes, letting users work from their personal systems *is* a
security risk, but there are ways to reduce that vulnerability.
