The hunt for weakness

Every lock has a flaw.
Fenrir finds it first.

A full vulnerability scanner pointed at a site you own — mapped, attacked, graded on one severity ramp, and written up so the person who has to fix it can read it.

One pass, five stages

Built to be believed

A scanner that overstates is worse than no scanner. These are the rules it holds to.

A failed scan says so

If the target could not be reached, the run is reported as failed — never as a clean result with zero findings.

One severity ramp

Severity is decided in exactly one place. A CVE is shown as evidence beside a finding, never as a reason to re-grade it.

Every run starts clean

Each scan gets a fresh scanner session, so last month's alerts cannot leak into this month's numbers.

Grouped, not dumped

Hundreds of raw alerts become a handful of findings with instance counts, so the list is one a human can work through.

Drivable by machine

A v1 REST API with per-client bearer keys, so another product can queue scans and read findings without a browser.

Many clients, one console

Built for people who look after other people's websites — each account's scans and findings stay its own.
