Your web app is doing things you never told it to do. We find those things, prove them, and hand you the fix — in plain English, with the evidence attached.

The honest partNo site is 100% unhackable, and anyone who tells you otherwise is selling something. What we sell is the highest-signal picture of where you are exposed today — and the shortest path to closing it.
Three things break most sites. None of them are exotic.
01Broken access control — the number one item on the OWASP Top 10, and the one we find most.
What that looks like: changing an order ID in a URL and seeing somebody else's invoice. We check every ID-shaped parameter you expose.
02Injection and cross-site scripting, in forms, URLs, headers and file names.
What that looks like: a display name that runs in your admin's browser. We prove it with a harmless marker, never a live payload.
03Stale subdomains, open admin panels, debug endpoints, leftover keys in client bundles.
What that looks like: a staging box from 2023 with last year's database on it, still resolving, still public.
Your attack surfaceEvery engagement starts by mapping what the internet can actually see of you: hosts, subdomains, endpoints, open ports, third-party embeds. Usually it is more than the founder thinks.
Drag to orbit. The lit nodes are the ones that would go on the first page of your report.
How we map it →Plus written authorization to test it, and credentials if you want the logged-in areas covered. We agree the scope and the window in one short call.
Step two · days 1–4Automation does the sweeping. A human does the confirming, the chaining, and the business-logic abuse a scanner cannot imagine.
Step three · day 5Every finding with severity, reproduction steps, evidence and a specific fix. Then a call to walk your developer through it, and a free re-test.
A sanitized report from a real engagement: eight findings, ranked, each with the request that proves it and the change that closes it.

No. We test in an agreed window and stop at proof — we demonstrate a vulnerability, we never destroy or exfiltrate data.
No. Every finding is written twice: once for you, once for whoever will fix it.
No, and we will never say we can. We reduce the surface and tell you the truth about what is left.
No. Scanners produce noise. Everything in your report was reproduced by hand before it was written down.
