About this course

A foundational OSINT course for aspiring intelligence analysts, investigators, security professionals, researchers, and decision-support practitioners. Learners develop the mental models required to distinguish data from intelligence, understand the OSINT lifecycle, evaluate sources, manage uncertainty, conduct ethical collection, and produce defensible intelligence assessments from publicly available information.

What you'll learn

  • ✓ Explain the purpose, scope, and limitations of OSINT and distinguish publicly available information from intelligence produced through analysis.
  • ✓ Describe the OSINT lifecycle from requirement definition and collection through evaluation, analysis, production, and dissemination.
  • ✓ Evaluate OSINT sources by considering reliability, credibility, provenance, bias, relevance, and uncertainty.
  • ✓ Corroborate publicly available information across multiple sources and identify gaps, contradictions, and confidence levels.
  • ✓ Produce OSINT intelligence assessments that clearly separate collected facts, analytic judgments, assumptions, implications, and confidence.

Course content

Module 1: 1. Understanding OSINT: Public Information and Intelligence

Establish the foundations of OSINT by exploring what open source intelligence is, how it differs from publicly available information, why organizations use it, and how analysts transform observations into defensible intelligence.

Module 2: 2. The OSINT Analyst Mindset: Questions, Sources, and Evidence

Develop the analytical mindset required for OSINT by understanding intelligence questions, source selection, evidence evaluation, corroboration, and responsible reasoning under uncertainty.
