The ZoomEye alternative - English-first and EU-based
Cyberspace asset and host discovery with perceptual favicon search, full WHOIS/registrant intelligence, an OSINT tools suite and an MCP server.
Profundis is a unified internet-intelligence search engine. Like ZoomEye, it lets you search cyberspace assets - hosts, services and exposed infrastructure - with a powerful query syntax.
Profundis is English-first and EU-based, and adds perceptual favicon similarity, full WHOIS with reverse/registrant lookups, DNS, TLS certificates, virtual hosts and a broad OSINT tools suite - all unified under one field:value syntax with an official MCP server for AI agents.
Why Profundis
01A unified internet-intelligence engine - exposed hosts and services, DNS (live + historical/passive), WHOIS (with reverse/registrant lookups), TLS certificates and virtual hosts - all searchable in one place with a field:value syntax (wildcards, AND/OR/NOT).
02Favicon perceptual-similarity search (MMH3 + visual similarity) that finds visually similar favicons, not just exact icon-hash matches - Profundis’s signature differentiator.
03A full OSINT tools suite: typosquatting scanner, subdomain enumeration, registrant explorer (reverse-WHOIS corporate recon), analytics-ID lookup, domain portfolio analyzer, entity-intelligence flow graph, ASN details and reverse-IP.
04Operated by Perspective Analytics SAS, a software company based in France.
05An official MCP (Model Context Protocol) server, so AI agents like Claude can call Profundis search as native tools - AI-agent-native distribution.
