Coverage
List every non-system table. Verify that RLS is enabled and that intended client-facing tables have policies rather than assuming one protected table represents the schema.

Vibe Coding Security: How to Secure AI-Built Apps Before You Ship
Vibe coding security means verifying the security boundaries of an AI-built application with current evidence—not assuming generated code is safe or unsafe. Check database access, identity and authorization, secrets, dependencies, and deployment configuration before launch, then repeat those checks as the code changes.

The direct answer
What does vibe coding security mean?
It is the security workflow around software created quickly with prompts, agents, templates, and managed services. The underlying risks are familiar; what changes is the pace, the number of generated decisions, and how easily working behavior can be mistaken for a verified security boundary.
AI-built code is not automatically insecure. It still needs the same review discipline as human-written code, applied to the database, repository, identity layer, dependencies, and deployed environment.
Why the workflow changes
Working software can still have unverified boundaries.
Prompt-driven development compresses implementation time. Security evidence has to keep up with that speed.
- Connect01
Read the real stack
Inspect the connected database, repository, and deployment rather than reviewing a pasted code sample in isolation.
- Verify02
Run repeatable checks
Collect direct evidence for access controls, exposed credentials, vulnerable dependencies, and deployment posture.
- Decide03
Report what is known
Separate verified findings from missing or stale evidence, and keep remediation under human approval.
Common failure categories
Where AI-built apps most often need deliberate review.
Database access
RLS + policies
A generated schema can work perfectly while a table has Row Level Security disabled, no policies, or a policy that only checks whether any user is signed in.
Secret exposure
Keys + env plumbing
Service credentials can leak through public-prefixed environment variables, committed files, browser bundles, logs, or examples copied into the application.
Identity boundaries
AuthN is not AuthZ
A valid session proves who a user is. It does not prove that user may read another account's record, call an admin action, or modify a shared resource.
Supply chain
Dependencies
Fast prototyping adds packages quickly. Known advisories and abandoned packages still need review even when the generated code around them looks reasonable.
Deployment posture
Production config
Preview protection, environment-variable scope, webhook verification, and production-only settings can differ from the local environment where the app was generated.
Database and authorization
Row Level Security is a boundary, not a checkbox.
For Supabase-backed apps, table-level RLS and policy behavior determine which rows browser clients can reach.
Correctness
Read the policy expressions. A policy can exist and still be too broad if it checks only for a session or omits tenant and ownership constraints.
Authorization
Review server actions, APIs, storage access, and admin workflows separately. Authentication alone does not authorize an operation.
Migrations
Treat generated migrations as security-sensitive code because they create roles, policies, functions, grants, and new public data paths.
Pre-launch checklist
What should you check before shipping a vibe-coded app?
- Every required connector is active and readable
- RLS is enabled on every intended table
- Policies enforce ownership or tenant boundaries
- Service-role and private keys stay server-side
- Auth callbacks and redirects are constrained
- Admin actions perform explicit authorization
- Dependencies are checked for known advisories
- High-risk auth, webhook, and env files are reviewed
- Deployment variables have the intended scope
- Production and preview access controls are verified
- Findings have an owner and remediation decision
- Evidence is refreshed after material changes
Sentrail methodology
Seven required checks feed one evidence-gated verdict.
Sentrail reads connected systems, timestamps the result of each check, and reports insufficient evidence when a required check has not run, failed, or gone stale.
Connectivity
Needs Supabase + GitHub
Confirms the connectors an audit depends on are actually active, so no verdict is ever computed with a blind spot.
Database RLS
Needs Supabase
Reads every non-system table and its policy count to catch tables with Row Level Security off, and tables with RLS on but zero policies.
Supabase advisors
Needs Supabase
Pulls Supabase's own security and performance advisor lints — exposed views, definer functions, unsafe function search paths, auth configuration.
Code scan
Needs GitHub
Searches your connected repositories for service-role keys and other credentials sitting in client-reachable paths or public-prefixed env vars.
High-risk file review
Needs GitHub
Locates and reads the security-critical files — auth handling, middleware, webhooks, env plumbing, migrations — and reviews what they actually do.
Dependency audit
Needs GitHub
Resolves your package manifests and checks each dependency against the OSV vulnerability database for known advisories.
Deployment posture
Needs Vercel
Classifies deployment environment variables by risk and inspects deployment protection settings on the hosting side.
Replace launch confidence with launch evidence.
Connect the systems your app depends on, run the required checks, and see what is verified, blocked, or still missing before you ship.
