Plain-English report
Every finding with severity, business impact, proof and the exact fix.
Methodology
How I actually test your SaaS.
The Zero-Leak method: a transparent process, mapped to the OWASP API Security Top 10, driven by one question — what would leak, and how fast? Written authorization first, always.
01
Scope & written authorization
We agree exactly what's in scope and you authorize it in writing. No target is touched without it.
02
Map your stack
I map your real surface — Supabase, APIs, auth, Stripe, secrets — the way an attacker enumerates it.
03
Find the holes
Manual testing where SaaS actually breaks: RLS, broken access control, exposed secrets, payment logic.
04
Prove the impact
I safely demonstrate real impact — like retrieving the customer list — so severity isn't a debate.
05
Report in plain English
A founder-readable report: what's broken, the proof, the business impact, and the exact fix — prioritized.
06
Fix together & free retest
I walk your team through the fixes, then re-test them for free and confirm the hole is closed.
Deliverables
What lands on your desk.

The customer-list test
If your data can be pulled, I show you exactly how — and how to stop it.
◆
Prioritized fixes
Ranked by real risk, written for the people who'll actually ship them.
◆
Criticals, same day
Anything critical is flagged the day I find it — never held back for the report.
◆
Free retest
Proof your fixes actually closed the hole — not just a promise.
◆
GDPR context
What each finding means for your GDPR / CNIL exposure, in real terms.
Standards & stakes
Grounded in real frameworks — and real consequences.
I test against recognized references — and I spell out the real stakes. A hole closed means no leak → no GDPR/CNIL → no fine → customer trust intact → you can go after bigger accounts.

Everything runs under your written authorization — nothing else, ever.

I'll send a redacted example so you know exactly what you get. And the guarantee holds: zero critical vulns found, the Zero-Leak audit is free.
