It's been my experience that there are 2 types of security people.
1. Are the security people who got into a security because it was one of the only places that let them work with every part of the stack, and exposure to dozens of different domains on the regular, and the idea of spending hours understanding and then figuring out ways around whitelist validations are appealing
2. Those that don't have much technical chops, but can get by with a surface level understanding of several areas and then perform "security shamanism" to intimidate others and pull out lots of jargon. They sound authoritative because information security is a fairly esoteric concept and because you can't argue against security like you can't argue against health and safety, the only response is "so you don't care about security?!"
It is my experience that the first are likely to work with you to help figure out how to get your application past the hurdles and challenges you face viewing it as an exciting problem. The second view their job as to "protect the organization" not deliver value. They love playing dressup in security theater and their depth of their understanding doesn't even pose a drowning risk to infants, which they make up for with esoterica, and jargon. They are also unfortunately the one's cooking up "standards" and "security policies" because it allows them to feel like they are doing real work, without the burden of actually knowing what they are doing, and talented people are actually doing something.
Here's a good litmus test to distinguish them, ask their opinion on the CISSP. If it's positive they probably don't know what the heck they are talking about.
