Continuously, not once. Security is not a launch-day phase, because the bugs that matter in AI-built apps, like broken authorization and IDOR, do not throw errors and do not show up in tests. They pass review and sit in production. The practical rule: verify on every change that touches authentication, data access, or money, and verify again after the AI edits the code. RedMirror runs that check inside your coding agent, on your machine.
A habit. The launch-day security audit is a leftover from a world where code stopped changing after you shipped it. AI-built apps do the opposite: you keep prompting, the model keeps rewriting, and the version live tonight is not the version you audited last week. A single pass at launch certifies a snapshot that no longer exists. What holds up is a check tied to changes, one that reruns whenever the code that guards data or money moves.
Not every diff. The ones that decide who can do what and who can see what:
A change to a button color does not need a security check. A change to how an order is fetched, or a brand-new admin route, does.
Yes, and this is the step people skip. You ask the model to "clean this up" or "add a field," and in the process it quietly drops the ownership check two functions away. The app still runs, the feature still works, and the hole is now open. The edit that introduced it looked harmless in the diff. Re-verify after the model touches anything in the list above, because "it still works" is exactly what a broken authorization check looks like.
That is the goal. A check that proves whether a bad state is reachable can sit in CI and gate the merge, so it runs on every pull request without anyone deciding to run it. The reason it survives as a gate, when noisy scanners get switched off, is that it only fails on a proven, reproducible path into a bad state, not on a maybe. A gate the team trusts is a gate the team leaves on.
RedMirror proves reachable logic, authorization, and state bugs, the class that hides behind a clean-looking diff: IDOR and broken access control, value or balance conservation, lifecycle and ordering, unbounded growth, integer under/overflow. It is not a secrets scanner or a dependency (SCA) tool, so for a committed .env, a key baked into your frontend, or a vulnerable package version, pair it with a secret scanner and an SCA tool. Match each job to the tool that actually does it.
curl -fsSL https://dist.redmirror.io/install.sh | sh redmirror-reflect license activate <key> redmirror-reflect init claude # or: cursor, windsurf, codex, gemini, pi # then, on any risky change: "verify this change for reachable auth and logic bugs"
Ongoing. A launch-day security pass goes stale the moment the AI rewrites the code, which in an AI-built app is constantly. The bugs that matter do not announce themselves, so a check that ran once tells you nothing about the version you shipped this afternoon. Treat verification as a habit tied to changes, not a phase tied to launch.
Any change that touches who can do what or who can see what: authentication, authorization, data-access queries and endpoints, payments and pricing, and multi-tenant boundaries. A change to a button color does not need one; a change to how an order is fetched, or a new admin route, does. When in doubt, a change that moves data or money needs a check.
Yes. A model improving one thing can silently drop an authorization guard somewhere else, and because the app still runs, nothing flags it. Re-verify after the AI edits the code, not only after you write it. Asking the model whether it is still secure does not count, because it cannot see the deployed app.
Yes, and that is the point. A verification step that proves whether a bad state is reachable can gate a merge in CI, so it runs on every change without anyone remembering to run it. Because it only fails on a proven, reproducible path, teams do not learn to ignore it the way they ignore a noisy scanner.
