Proof, not guesswork

Exploit. Prove. Advise. Re‑test.

Sintropyc drives your live product the way a customer does — clicking through real screens and flows — until something gives. Each break is demonstrated with a working exploit, comes with the precise change your team should make, and is attacked once more after you ship it.

The scale of it

Every day, hundreds of thousands of web-sites are attacked.

And this is what hackers walk away with.

A quiet question

Do you have a web-site?

01 — A live session

Watch the agent break something, then close it.

02 — The problem

Scanners return 500 “possible” issues. Not one of them proven.

A classic security scanner is a list of guesses. “There might be a SQL injection here.” “This string looks like a secret.” You pay for 300 lines, 280 of which are false alarms — and working out what is actually exploitable still needs a person that a team of under 20 usually doesn't have.

Sintropyc doesn't guess. Sintropyc exploits. If a vulnerability can't be proven with a real effect, it never reaches the report.

03 — The loop

Proven → advised → proven again.

A loop that can't be faked: the same attack lands before the change and fails after it. That is what proof means.

✖ VULNERABLE — the exploit lands
◆ GUIDANCE — the change to make
✔ CLOSED — same exploit blocked
app.example.com/search?q=
<img src=x onerror=alert(1)>
> payload injected
> DOM exec detected
✖ VULNERABLE
— advice · render.js:42
root cause: el.innerHTML = q
use textContent instead of innerHTML
add CSP: script-src 'self'
◆ GUIDANCE ISSUED
<img src=x onerror=alert(1)>
> re-test: same payload
> no DOM execution · escaped
✔ CLOSED
04 — What we prove

We prove effect, not reflection

Every class below is judged by real effect — a landing exploit, not a reflection. The set keeps growing.

01 XSS Code executes in the DOM — not merely reflected in the response. DOM exec detected
02 SQL injection Confirmed by a distinguishable effect in the application's response. boolean delta confirmed
03 Command injection Command output visible in the response — a safe echo, nothing destructive. echo marker returned
04 SSRF A canary reaches a controlled channel — the request really left the box. canary received
05 Open redirect Redirection to an external, controlled address. 302 → external host
06 Path traversal A system file is read — confirmed by a content signature. signature matched
07 IDOR Another account's record returned — a single changed id is enough. foreign object read
08 CSRF A state-changing request accepted from an off-site origin. cross-origin write
09 JWT forgery A self-signed token accepted — any session becomes reachable. forged token accepted
10 API keys exposed A live secret reachable from the client — confirmed valid, never printed. key validated
Audit engine
Live secret validation

Found a key? One harmless read-only call answers whether it's live or revoked. A test key returns 401 and the false alarm is dropped. The raw key never appears in the report or the logs.

Audit engine
Open database / RLS probe

Supabase / Firebase: we check anonymous access to tables that should not be visible. Row values never leak — we record only the fact of exposure.

While the agent attacks, static analysis runs quietly

Alongside the live test, static code analysis runs in the same sandbox. Its output ships as a separate appendix to the report — a second angle of view. We don't sell a number of scanners; we sell a proven finding. Static analysis simply backs up whatever the live exploit couldn't reach.

05 — Pricing

One-off, or continuous.

Run a single proof scan across your web-site, or move to a monthly plan built for teams that ship continuously — up to 10 runs a month, a re-test after every fix and scans scoped to a single class. Whichever you pick, you pay for the result: every finding proven.
