You can start very lightweight with doing spec driven development with the help of AI if you're at a size where you can't afford that. It's better than nothing.
But the important part is you, as a company, should inherently care.
If you rely on an auditor feedback loop to get compliant you've already lost.
It has the potential to be incredibly impactful, but often devolves into box ticking (like many compliance functions).
And it's really hard to find technical people to do the work, as it's generally perceived as a cost centre so tends not to get budget.
Like cool, it's a great idea and would potentially produce positive results if done well, but the roles pay half the engineering roles, and the interviews are stacked towards compliance frameworks.
There's very little ability to fix a large public company when HR is involved
So many controls are dubious, sometimes even actively harmful for some set-ups/situations.
And even moreso, it's also perfectly feasible to pass the gates with a burning pile of trash.
I’ve been at companies where we cared deeply about security, but certain compliance things felt like gimmicks on the side. We absolutely wanted to to do the minimum required to check that box so we could get back to the real work.
Compliance gets taken quite seriously in an industry where one of your principal regulatory bodies has the power to unilaterally absorb your business and defenestrate your entire leadership team in the middle of the night.
I've seen this up close. The regulatory bodies as a rule are understaffed, overworked and underpaid. I'm sure they'd love to do a much better job but the reality is that there are just too many ways to give them busywork allowing the real crap to go unnoticed until it is (much) too late.
None of those are likely.
This is the industry that missed Enron, WorldCom, Wirecard, Lehman, and many others.
