I will do a security audit of your ai built or vibecoded web app
Visian Systems
About this gig
I find and fix the security problems in apps built with Lovable, Bolt, v0, Replit, Cursor and Supabase. AI tools ship fast, but they often leak API keys to the browser, leave database tables open and skip access checks on API routes.
What I check
- Keys and tokens exposed in your front end
- Supabase row-level security and Firebase rules
- Login, sessions and access control: can one user see another's data?
- Injection, XSS, SSRF and unsafe file uploads
- Headers, HTTPS, exposed files and outdated libraries
What you get
- A report with every finding ranked by severity (CVSS), with evidence and fix steps
- Every result confirmed by hand
- On Premium: I fix Critical and High issues, re-test them and sign a re-audit letter
How it works
1. You confirm you own the app, and we agree on the scope
2. I test safely, never destructively
3. You get the report and a walkthrough
4. I fix, re-test and close it out (Premium)
Not sure where to start? Message me your URL, and I will tell you what it exposes publicly.

FAQ
Is my vibe coded app secure?
Often not by default. In a September 2025 study by RedHunt Labs, about 1 in 5 of 130,000 vibe coded sites leaked at least one secret, such as an API key. An audit tells you for sure.
What is the difference between the external scan and the code audit?
The scan sees what anyone on the internet sees, with no code access. The code audit reads your code to find what is invisible from outside, like missing access checks, open data rules and injection.
Can you fix the problems, or only report them?
Both. Basic and Standard give you a report with fix steps for your team. Premium includes fixing up to 10 Critical and High findings as pull requests, re-testing each one and a re-audit letter.
Will testing break my app or touch my users' data?
No. Testing is non-destructive: no load testing, no data deletion and nothing intrusive in production unless you agree in writing. Code access is read-only until you approve fixes.
Do I need to give you my passwords or API keys?
No. For the code audit I need read-only repo access and the names of your environment variables, never their values. For logged-in testing, create a test account and send it through Fiverr.
Does this make my app 100% secure?
No one can honestly promise that. I fix and verify every finding in the agreed scope. New code brings new risks, which is what the CI/CD security extra is for: it checks every change before release.
What is a re-audit letter, and who is it for?
A signed letter stating the final status of every finding in scope: fixed, risk accepted by you, or out of scope. Founders use it for customer security reviews, investors and enterprise sales.
Which platforms and stacks do you cover?
Any, to be honest. We have a team of 25 people. We've worked with clients using Lovable, Bolt, v0, Replit, Cursor, and Base44 apps, plus Supabase and Firebase backends, Next.js, React, Node.js, Python, and .NET. Ask me about anything else before ordering.
Do you do full penetration tests?
Yes, as a custom offer. A manual pentest attacks a staging copy of your app to prove what is really exploitable; it takes 2 to 4 weeks and starts at $950. Message me the scope for a quote.
What do you need from me to start?
Confirmation that you own the app, the URL, and for code audits read-only repo access, a short note on how the app works and a test account. The requirements form walks you through it.
