App Security Audit
Your app has problems you can't see.
Your users will find them.
Apps built fast, with AI tools, no-code, or a rushed freelancer, almost always ship with the same silent flaws. Everything looks fine, right up until real users and real money arrive. We find those flaws first, and hand you the exact fixes.
Fixed price, agreed before we start. Bubble, Lovable, Base44 and custom-code apps.
What actually goes wrong
The flaws we keep finding in apps that "work fine"
Every one of these comes from real rescue projects. Most apps we review have at least three.
Every user can read every other user's data
The single most common flaw we find. Auth 'works', people log in, they see their dashboard. But with no privacy rules underneath, any user who opens the network tab can pull everyone else's records: names, emails, messages, documents. You never notice in testing, because in testing you're the only user.
Payments succeed. Cancellations don't.
The happy path is wired up, so money comes in and everything looks fine. Then a card fails, a subscription cancels, a webhook doesn't arrive, and nothing is listening. People keep paid access for free, or paying customers get locked out. Either way, you find out from an angry email, not from your app.
One leak, and it's a legal problem
If your app holds personal data of users in Europe, the UK, California and a growing list of places, a leak isn't just embarrassing, it can trigger mandatory breach notifications and regulator attention. 'I didn't know my app exposed that' is not a defense anywhere.
Your reputation dies in a screenshot
It takes one curious user to find an open endpoint, screenshot it, and post it in the exact community you're selling to. Trust that took months to build is gone in an afternoon, and that thread outranks your homepage forever.
It works with 10 records. Not with 500 users.
Flat databases, unindexed searches, workflows that fire twice, none of it hurts while it's just you clicking around. The day real traffic arrives is the worst possible day to discover it, because now every fix happens live, with customers watching.
When something breaks, users see... nothing
No error handling means failures are silent: a white screen, a button that does nothing, an order that vanishes. Users don't report it, they just leave. You lose revenue for weeks before anyone tells you why.
None of these show up while you're the only user. That's exactly why they survive until launch day.
The audit
We go through your app the way an attacker would
Access control
Can any user reach data or actions that aren't theirs? Every role, every endpoint.
Data exposure
APIs, privacy rules and database settings that quietly leak user data.
Payment flows
Failed payments, cancellations, webhooks, price manipulation, the whole unhappy path.
Privacy basics
What you collect, where it lives, and what could get you in trouble.
Load & scale readiness
What breaks first when real users arrive, and how badly.
Launch blockers
A clear line between 'fix before launch' and 'fix soon'.
Know exactly where you stand, before your users do
- A written report, every finding ranked by severity
- The exact fix for each issue, in plain English
- A call to walk through the results together
- Optional: we implement the fixes at a fixed price
The audit pays for itself the first time it catches something a customer would have found.
