Supply-Chain Dependency Mapping
Map what a domain DEPENDS ON — every external provider woven into its infrastructure, grouped by function (DNS, mail, email delivery, hosting, physical), with the dependency chains and single-vendor concentration (SPOF) signals.
Free tier — no credit card. Runs up to 3 hops deep; Pro goes to 5.

Map the digital estate an indicator belongs to. Starting from any domain, IP, ASN or prefix, this works out the true owner — even behind privacy WHOIS and CDNs — via the atlas operator, the canonical registrant organization and the registrant email, then enumerates everything that owner owns: the subdomain namespace, the rest of its domain estate, the networks and prefixes that host it, and the facilities it physically sits at. Assets run by someone else (CDN, managed DNS, cloud) are marked as the vendor border, not owned.
Threat Investigation
The deep-dive you run when something looks bad and you need the full story. Give it one indicator and it works outward across its whole footprint — the related domains, the real servers behind any CDN, the neighbouring infrastructure — and checks each piece for known abuse. You get one coherent read on how dangerous it is and why, with safe next steps to pivot on. Reach for it when a quick check says 'look closer.'
Attack-Surface Mapper
See your organisation the way an attacker does. Give it a domain and it maps the full external footprint — every subdomain, the name and mail servers, who registered it, the third-party services it leans on, and the wider web of sites it connects to — and scores the exposure. The starting point for shrinking what's reachable from the outside.
