I work in info sec, and in one of the "Who's Hiring" posts a few months ago (do we still do those? I haven't seen one in a while) I asked "why are startups never hiring security guys?", because I never see a security engineer position open in those topics. I never got a response. To me that indicates the response is "we don't". Listen, guys. I don't care how small you are. If you are handling PII or credit card data…
Why does sec get breached? Marketing wants easy access to all data, deep learning wants easy access, lots of data is in transit.
Security is not convenient for operations, therefor companies have sec on paper and audits and stuff but no real sec.
