I spent the last 4 years integrating with various hardware vendors (non-iot market but the problems are the same) for my employer's Saas offering. Hardware companies are great at making reliable hardware but they have very little to no understanding of security or heck, even software in general. Most of the time we find that their hardware engineers are writing software and and the entire protocols are wide open usually without any built in security mechanisms. Some transmit sensitive information completely in the open. If we ever come across a vendor who understands SSL that's about as good as it gets.
