I was just part of a hallway conversation here at work about whether
many financial services institutions use Ruby on Rails in their secure
areas. For example, how many banks are using it in their online
banking applications, and what were their concerns about security?
If you work in the financial services arena (banks, accountancy firms,
etc.) and you've used Ruby on Rails, or if you're convinced that it
isn't secure enough to be used for financial transactions, would you
mind sharing your experiences/opinions?
