IaC security scanning caught something last week that 3 reviewers missed.
An assistant wrote a chunk of our Terraform. It read clean, been approved and it had a security group open to the world on a port that had no reason to be public. The diff looked fine, the person who prompted it did not clock the CIDR and neither did the reviewers.
Luckily, a pre apply scan caught it. The config was syntactically perfect and quietly wrong, which is the exact thing eyes slide over.
What are you gating on before apply, is it advisory, does it really block? Advisory did nothing for us until we made it a hard gate.
