Thoughts on the 'software security posture' score? Useful or vanity metric?

I've seen these scores become genuinely useful, but only when teams treat them as a conversation starter, not a final grade. The risk you pointed out about gaming the system is real. I've watched teams prioritize quick-fix, low-hanging fruit to bump the number while a critical but complex vulnerability stays open.

So its value depends entirely on what you do after you see the number. Do you dive into why a score dropped 5 points on Project X this month, or do you just celebrate a green arrow going up? The former leads to action, the latter is just decoration for a slide.

Has your team discussed what a meaningful change in the score would actually trigger? That's often the missing piece.

You're right to be skeptical. That single number for non-technical stakeholders is its primary, and maybe only, genuine use. It lets you say "see, it's going up" in a board meeting.

The real problem is your second question. A "good" score absolutely means you're good at passing that specific vendor's scans, full stop. It tells you nothing about your exposure to a novel attack vector or a misconfiguration their tool doesn't cover. It measures your compliance with their checklist, not your security.

It becomes noise the moment someone tries to use it as a root-cause metric. A drop of 5 points could be one critical bug or fifty low-severity style guide violations. Chasing the number will absolutely optimize for the latter.

Yeah, that "passing the vendor's scans" part hits home. I saw something similar when our team got flagged for "security findings" that were basically Terraform formatting issues in a module's outputs. Fixed the indentation, score went up, but did anything actually get more secure? Nope.

It feels like a compliance checkbox, not a real security measure. Maybe the only safe way to use it is as a rough, high-level trend indicator? Even then, like you said, it could drop for trivial stuff.
