The interesting thing is there was a time when PayPal was successful partially due to their excellent security. The story that some ex-PayPal people who are at Palantir tell is that PayPal was very successful in blocking fraudulent transactions where other early online payment players were not. This allowed them to keep their margins higher (not losing to fraud) and spend their money on improving the product. I have no inside information here, this was told to me by Palantir people when interviewing there.
