Overview
Profundis helps you investigate internet infrastructure through hosts, DNS records, TLS certificates and WHOIS observations. Start with a domain or IP, inspect its supporting records, and follow the connections worth investigating.

Interpret the evidence
Records describe what was observed, sometimes at different dates and with partial coverage. Shared hosting, an icon or a registration value is an investigation lead, not proof of common ownership. A missing observation does not prove that a service is offline or that an asset does not exist.
Searches and monitoring have different purposes. A search retrieves indexed observations now. A watch collects or matches future observations under its saved rules and budget. It does not turn Profundis into a continuous live availability check.
