I find that security, architecture, etc is exactly the kind of skill that takes 10-15 years to hone. Every boot camp, training provider, educational foundation, etc has an incentive to find a shortcut and we're yet to see one.
A "basic" understanding in critical domains is extremely dangerous and an LLM will often give you a false sense of security that things are going fine while overlooking potential massive security issues.
Somewhere on an HN thread I saw someone claiming that they "solved" security problems in their vibe-coded app by adding a "security expert" agent to their workflow.
All I could think was, "good luck" and I certainly hope their app never processes anything important...
