Had the same experience with a large communication equipment manufacturer (who you'd think would understand firewall rules better!). This is pretty normal to be honest. I doubt there are many companies who are 100% on top of things, but I get the sense that's more down to the department or the individuals you're dealing with. There are people who don't think things through everywhere. I certainly wouldn't bear a grudge against IBM for too long!
