Depth

Deep scan Adds certificate transparency, link crawling and search-engine collectors, with a larger entity budget. Slower — it still runs on the worker, so the browser never waits.

Or analyze a file

Reads email messages (alignment, the Received chain, and where it really came from), lists of IPs or domains, CSV and JSON exports, and metadata from images, PDFs and Office documents. The file is parsed in memory and never stored, and you get the same confirm screen — nothing is collected until you choose what to run.

Dry-run plan first. Nothing scrapes until you confirm a run on the next screen.
Passive & defensive use only — read the policy

Quick reputation check

One host against public blocklists and malware feeds (Spamhaus, OpenPhish, abuse.ch and more) — or offline numbering-plan validation for a phone number. Not a full investigation — for that, use the search box above.

Absence of a listing is not proof the host is safe. A valid phone format is not proof of who answers or whether the number is spam.

Nothing in mind? Run one of these — same check, real answer:
