    Just to add some fuel to the fire, I agree with Ron. Security seems almost
    secondary to many B2B implementations. Almost a "if we trust them to
    partner, why worry" kind of attitude.

    If you want to look at things that you can do though, there is a relatively
    short bullet list[1]:

    Use VPNs between sites
    Terminate VPNs into DMZs
    Implement firewalls at the termination point
    Grant access only to those resources in the DMZ that each company needs
    access to
    Never grant access to your production network or resources

    [1] This is by no means an exhaustive list, but at least give a starting
    point. The devil of course is in the details.
