Vibe Coded Apps AI-assisted, engineer-reviewed

Vibe-coded SaaS security

# Protect customer data in your AI-built SaaS.

We audit and secure multi-tenant SaaS applications built with AI coding tools. We ensure one customer can never view, edit, or leak another customer's data, verifying row-level security, API authorization, secret storage, and webhook signatures before you take paid subscribers.

Discuss your app [Explore our work](https://foundrysoft.co/work)

## What we can help with

### Tenant isolation verification

Audit every database table and query to ensure queries are strictly bounded by organization and user IDs.

### IDOR and API authorization audit

Test API routes and server actions against Insecure Direct Object References to prevent unauthorized record access.

### Secret and credential protection

Audit client-side bundles and environment configurations to ensure private API keys and tokens are never leaked.

### Webhook & payment security

Verify cryptographic signatures on Stripe or LemonSqueezy webhooks to prevent subscription spoofing.

Before implementation

## Start with the app and the outcome.

Share what you need to achieve, what exists today, and the constraints. We use those inputs to agree the review or build scope.

1.  01

    ### Review the starting point

    Understand the current code, data, dependencies, and intended users.

2.  02

    ### Agree a defined scope

    Choose the workflows, deliverables, access, and acceptance criteria.

3.  03

    ### Verify and hand over

    Review changes, check the release, and document how the app is operated.

## Frequently asked questions

Why are AI-generated SaaS apps vulnerable to tenant data leaks?

AI tools frequently write straightforward SELECT or UPDATE queries without joining the user's organization ID, or they rely on client-side state for filtering rather than server-side enforcement.

How do you test tenant isolation?

We create multiple isolated test workspaces and attempt to read and write across account boundaries using crafted API requests and automated penetration tests.

What deliverables will we receive?

You receive an executive summary, a prioritized matrix of discovered vulnerabilities with reproducible proofs-of-concept, and pull requests with the fixes implemented.

Can you fix the vulnerabilities for us?

Yes. Our engineers can implement row-level security policies, middleware checks, and secure server actions directly in your repository.
