OSINT (Open Source Intelligence)

Definition
OSINT (Open Source Intelligence) is the practice of collecting and analyzing information from publicly available sources to produce actionable intelligence. According to NATO guidelines, OSINT sources include social media platforms, public records databases, news archives, academic publications, government filings, and domain registration records. In identity investigation, OSINT combines data from LinkedIn profiles, company filings, academic publications, and social media activity to construct comprehensive background profiles. Modern OSINT workflows use AI to cross-reference findings across 15-20 independent sources, achieving verification confidence levels from E1 (multiple corroborating primary sources) to E5 (single unverified source). The U.S. Department of Defense defines OSINT as "information that has been obtained from publicly available sources and has been validated through intelligence tradecraft."
How It Works
OSINT collection follows a structured workflow: requirement definition, source identification, data collection, processing, analysis, and dissemination. Analysts use automated tools to monitor social media feeds, scrape public databases, aggregate news articles, and compile government filings. The data is then processed to remove duplicates, normalize formats, and extract entities. Analysis involves pattern recognition, link analysis, and timeline construction. Modern OSINT platforms integrate with search engines, social media APIs, and public record databases to automate the collection phase, while AI models assist in entity extraction, sentiment analysis, and cross-referencing across sources.
Example
An OSINT analyst investigating a potential business partner might start with their LinkedIn profile, then cross-reference with SEC filings, academic publications on Google Scholar, patent filings, court records, and social media activity. By combining these sources, the analyst discovers the person claimed a degree from a university that has no record of their attendance — flagging a discrepancy that requires further investigation.
