3 Check the site

The deep probe sends real read-only GET requests to known paths (.env, .git, phpinfo) on your verified site — no exploit payloads. It runs only when you click it.

★ Deep scan (optional) — run on your own server

A single, read-only PHP file that reads the exact PHP version, risky php.ini settings and your composer.lock dependencies — things a remote scan can’t see. Read it before running it; it writes nothing.

✦ Help us decide: continuous monitoring

A one-off check tells you where you stand today. We’re considering building something that keeps watch for you — and emails you, in plain language, only when something genuinely new needs your attention. Less noise, fewer nasty surprises.

If enough people want it, we’ll build it — as a paid subscription. Join the waitlist to help shape it and lock in early-bird pricing.

We store only your email (and site, if given), in the EU, on the basis of your consent — never shared, never used for anything else. Unsubscribe or ask us to delete your details any time: privacy@senbonai.se.
