How OSINT Is Used in Cybersecurity
Threat intelligence analysts use OSINT to research threat actors, track infrastructure changes, and identify exposed assets. Penetration testers perform OSINT reconnaissance to map an organization's attack surface before an engagement. Security teams monitor OSINT sources for leaked credentials and data breaches that affect their organization.
