Load balancers do not provide any type of security. Load balancers
will only distribute the traffic and not deny it. If your ISP manages
all the security devices between you and the hosting facility then at
a minimum you will want to put an additional firewall on your side so
you can have some control of what accesses your network over this site
to site tunnel. This will probably be easier (politically not
technically) in a lager company.

Nobody is lobbying against the change but a senior developer that was involved in the original design points out that because of the load balancers in front of the servers, the world at large is not able to touch the machines and thus the potential for compromise is limited.

I'm looking for specific info related to the load balancers not commentary about the corporate LAN in this situation - even if the combination of the firewalls and load balancers provide 99.9% protection I think it is a bad idea and would most likely not pass PCI scrutiny.
