Business jargon for something that is absolutely unbreakable. For example, "The beta testers have been banging his code for the last month. It's bulletproof, and we're set to launch." It also refers to a business idea or project that will survive someone else's criticism (namely, a client's). For example, "Our methodology for building a best-in-breed vortal is bulletproof."
