This will change with time. I have thought, studied, talked, and written extensively on this general theme. What comes to mind to frame it for you is my "four principles:" [a]
1. Compromise is inevitable
2. Default-allow products always fail
3. 1 and 2 are not opinion or marketing spin, just simple truths
4. As an industry, we are still learning 1 and 2
Security is slowly shifting from an administrative IT function to an operational function. In IT, the business value comes from the products and people are a tax required to administer the products. In security operations, the business value comes from the people, products are just tools in their toolbag. [c]
Keep walking this dog and you realize basic IT activities for core infrastructure are critical for security, to the point the CIO will report to the CISO -- unless the CIO steps up. [b]
So - in short - your frustrations are accurate, but the winds are shifting. Companies will incresingly value top people for their internal staff/blue teams. It's going to take a few more years, but I believe it is inevitable.
