How the checkup works

A careful read of your whole site

Sutros looks around, decides what actually matters for your site, and checks it carefully. No fixing, no breaking, just a clear read.

1

We look around

We see what your website is built with and how old it is, the same way you'd notice a shop's paint is peeling.

Recon · fingerprint stack, versions, headers, SSL

We make a checklist

Based on what we found, we decide what's worth a closer look, so we don't waste your time on things that don't matter.

Orchestrator · LLM plans & prioritizes probes

We gently try things

We crawl your pages and run deep security checks: exposed files, leaked secrets, vulnerable libraries, weak encryption, and input handling, watching for anything broken or private that shouldn't be showing.

Agent + checks · browse, probe, collect evidence

Under the hood

deterministic

Recon & checks. A crawl plus scripted probes across TLS, security headers and CSP, CORS, cookies, exposed files (.env, .git, backups, keys), leaked secrets and source maps, vulnerable JS libraries, form and CSRF hygiene, and a conservative reflected-input (XSS surface) check. Reliable and safe, no model needed.

llm orchestrator

The brain. Reads recon output, decides which checks to run and in what order, and prioritizes by likely impact. Judgment, not raw execution.

ai agent

The explorer. A browser pass that navigates flows like a curious customer would, catching breakage scripts miss. Read-only: no transactions, detection not exploitation.

llm reporter

The writer. Turns structured findings into a plain-language report with an A–F grade, real-world impact, and a simple fix for each issue.

Look out for your neighbors

Built for Main Street, not hackers

The corner bakery running a five-year-old website deserves the same safety as a big company. Anyone can flag a local site that needs a hand.

Nominate a local business

Spot a neighborhood shop with a sketchy or broken website? Send them a friendly, no-jargon heads-up with a free checkup. They decide whether to run it.

We never scan without the owner's OK. This creates a friendly invite and a checkup link you can send them.

A badge that builds trust

Sites that pass their checkup can show this to customers, proof the doors are locked and the lights are on.
