Open-source intelligence
collection and analysis of data gathered from open and publicly available sources to be used in an intelligence or investigative context

Open-source intelligence (OSINT) is the collection and analysis of data gathered from 'open sources' (overt sources and publicly available information) to produce intelligence. OSINT is primarily used in national security, law enforcement, and business intelligence and is used by analysts to answer classified, unclassified, or proprietary intelligence requirements.
Definition
OSINT involves the gathering of and analyzing of publicly accessible information to produce usable intelligence.
The U.S. Department of Homeland Security defines OSINT as intelligence derived from publicly available information, collected and disseminated promptly to address specific intelligence needs. NATO describes OSINT as intelligence obtained from publicly available information and other unclassified data with limited public distribution or access. The European Union defines OSINT as the collecting and analyzing information from open sources to generate actionable intelligence, supporting areas like national security, law enforcement, and business intelligence.
In the private sector, companies like IBM define OSINT as the process of gathering and analyzing publicly available information to assess threats, inform decisions, or answer specific questions. Similarly, cybersecurity firms such as CrowdStrike describe OSINT as the act of collecting and analyzing publicly available data for intelligence purposes.
Categories
OSINT sources can be divided up into six different categories of information flow:
Media: print newspapers, magazines, radio, and television from across and between countries.
Internet: online publications, blogs, discussion groups, citizen media (i.e.
This brief starts where responsible research should: with the source description of “Open-source intelligence” as collection and analysis of data gathered from open and publicly available sources to be used in an intelligence or investigative context. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as collection and analysis of data gathered from open and publicly available sources to be used in an intelligence or investigative context. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 17, 2026. The linked authority identifier is Q1059178. The Library of Congress control number is sh2006001992. None of the 1 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
