post firewall deployment ROI numbers

[Tina Darmohray <tmd () STANFORD EDU>]

I'm looking for Return On Investment numbers from universities who have
deployed firewalls.  E.g., one university has shared that they reduced
their incidents by > 90% by firewalling their campus.  Another university
reduced their incident response staffing from 1.25 FTE to 1 FTE [10K
node network] through firewallng.

Do you have similar numbers you'd be willing to share?  I can summarize
to the group, or if you'd prefer your numbers not be widely posted, let
me know that too.

Thank you for your help!
