Intelligence X
European OSINT search engine and data archive indexing darknet sources, document leaks, WHOIS records and public data leaks for security and investigative research.

Intelligence X was established in 2018 by Peter Kleissner and operates from Prague, Czech Republic, as an independent European OSINT (open source intelligence) technology company. Unlike a conventional keyword search engine, the platform searches using “selectors” — email addresses, domains, URLs, IP addresses, Bitcoin addresses and IPFS hashes — across the darknet, document sharing platforms, WHOIS data and public data leaks.
The service also functions as a historical data archive comparable in concept to the Internet Archive’s Wayback Machine, letting researchers track how selectors and associated data have changed over time, and is used by both companies and government organizations for attack surface intelligence and threat reconnaissance work.
Innovation Matrix Assessment
A small, single-founder-led team maintaining and gradually extending a stable OSINT search product rather than shipping rapid new capabilities.
Selector-based search across darknet and leaked data sources speeds up investigative and reconnaissance work for security and OSINT teams, per the platform's own design.
A very small, apparently self-funded team with no disclosed institutional backing indicates limited growth momentum relative to venture-backed threat intelligence competitors.
The selector-based, historical-archive search model is a genuinely different approach to OSINT search, even if the underlying data sources overlap with other dark web monitoring tools.
No independent benchmark of data coverage or search accuracy was found; usage by both companies and government organizations suggests real-world utility, but this is not independently verified.
Specialized OSINT search over leaked and darknet data remains relevant for both attack surface reconnaissance and incident investigation work.
Why CISOs Should Care
Intelligence X gives investigative and security teams a way to search leaked data, darknet sources and historical infrastructure records by specific identifiers (domains, emails, IPs) rather than generic keywords, supporting both attack surface reconnaissance and incident investigation work.
What Makes It Different
Its selector-based search model and historical data archive approach differentiate it from typical dark web monitoring tools that focus on real-time alerting rather than deep historical search across leaked and darknet data sets.
The Matrix Verdict
40/100 — EMERGING / UNRANKED
A small, independently operated European OSINT utility with a genuinely useful and differentiated search model; valuable as a specialized research tool, though limited in scale compared with larger commercial threat intelligence platforms.
Editorial Note: Claims vs. Verified Findings
Founding and product details are drawn from Intelligence X's own site; data coverage and historical archive completeness claims are vendor-stated and were not independently verified.
