IMO, I think a root cause issue is that the "hacker types" who are most likely to want to start security software companies are also the least likely to want to implement the "boring" pieces of a process-oriented culture. For example, I can't speak so much for CrowdStrike, but it came out the SolarWinds had an egregiously bad security culture at their company. When the root cause comes out about this issue dollars-to-donuts it was just a fast and loose deployment process.
