Security for AI-native companies

Your app is live.
Is it actually
safe to be?

You built something real with Claude Code, Cursor, or Lovable. Most founders ship and hope for the best. MINUS tells you what's exposed, what it means, and how to close it — before someone else finds it first.

Free scan included for everyone on the waitlist at launch

84%

of AI-built apps contain at least one critical security vulnerability on their first public deployment.

The context

Built for the generation
that ships with AI.

Security has always been an afterthought for indie builders — not because they don't care, but because the tools that exist were built for enterprise teams with dedicated engineers and five-figure budgets. MINUS was built specifically for founders who move fast with AI tools and need to know if their product is holding up.

What's probably inside
your app right now

The four most common critical vulnerabilities in AI-built products. MINUS checks for all of them.

Critical

Exposed API credentials

Secret keys hardcoded into your codebase or committed to version history. One scan from a bad actor and your OpenAI or Stripe account is theirs.

Critical

Unauthenticated endpoints

API routes that execute sensitive operations with no identity check. AI-generated backends skip authentication constantly. It rarely shows up until it does.

High

Prompt injection

User inputs that reach your AI model without sanitization. A crafted message can override your system prompt and make your product do things you never intended.

High

Unsigned payment webhooks

Payment events processed without verifying their origin. If Stripe sends a "payment succeeded" — so can anyone else. Your app cannot tell the difference.

OpenAI API key exposed in repositoryCritical

Your production key is hardcoded in config/api.js line 34 and visible in your commit history. Any actor with read access can use it at your expense or pull your customer data.

→ Self-fix: migrate to .env · invalidate key · rotate immediately
Stripe webhook accepts unsigned payloadsCritical

Your payment endpoint at /api/webhook processes all events without verifying their origin. A crafted request can simulate any payment event and your system will treat it as real.

→ Let MINUS implement this — signature verification + full test suite included in the Fix planFix this for me
Prompt injection surface on /api/chatHigh

User messages pass directly to your model context without sanitization. A structured input can override your system prompt and instruct your AI to return data or behave in ways you never intended.

From founders who
found out early

Real vulnerabilities. Real resolutions. Before anything went wrong.

✓ Resolved in 48h
Exposed database credentials

"I had been shipping with my Supabase key visible for three months. MINUS caught it in the first scan and had a fix ready before I finished reading the report."

✓ Resolved in 24h
Fake payment vulnerability

"Our Stripe webhook had no signature check. Anyone could have faked a payment. MINUS flagged it as critical and their team had the fix deployed the same afternoon."

✓ Resolved in 12h
Prompt injection attack surface

"I didn't know prompt injection was even a real attack vector. MINUS showed me exactly where my app was exposed and closed it before I'd even told my co-founder."
