brink.
continuous adversarial security

We break in
so they don't.

Quarterly pentests are stale within a week. Brink runs autonomous attackers against your app 24/7 — IDOR, auth bypass, SSRF, the things real hackers actually use.

how we get in

Three things, on a loop.

A pentest is a snapshot. Brink is a movie that doesn't end — agents wake up, probe, write findings, sleep, repeat.

01step

You point us at staging.

A URL, an OpenAPI spec or HAR file, and a list of synthetic accounts. No agents in your code, no GitHub app, no SOC2-scope surface to argue about.

$ brink scope add api.acme.dev --auth=jwt --accounts=4
02step

We attack like real attackers.

Agents enumerate auth, map routes, hypothesize weaknesses, and exploit them. We chain primitives — an info leak feeds an IDOR feeds an account takeover.

→ 1,841 requests · 19 hypotheses · 3 confirmed exploits
03step

You get the proof and the fix.

Confirmed findings hit your inbox with a reproducible curl, captured session, suggested patch, and an open PR against the offending repo. Coverage is logged — even what we tried and failed.

attack surface

The things real hackers actually use.

Brink doesn't ship a list of CVEs. It ships the bugs that get apps owned in 2026 — the ones your scanner finds zero of.

// every finding is reproduced from a clean state before it reaches you.
// coverage is logged — even the attacks we tried and ruled out.

IDOR / BOLA
tenant-bleed via path & query params
Auth bypass

SSRF
webhook validators, image proxies, oembed
Race conditions

findings inbox

One inbox. Real exploits only.

Every alert is reproducible, owned, and labeled with a fix. No CVE lists, no severity inflation, no `medium` that nobody reads.
