FactFinder: The OSINT Express
Three live classes on OSINT investigative method, led by a Polk Award-winning journalist
+1 more
The OSINT Express is a three-day, three-class course from FactFinder, built by lawyer and Polk Award-winning investigative journalist Gisela Perez de Acha, who opened the first OSINT reporting class at UC Berkeley.
This is not a tools workshop. Tools change every six months, so the focus is on method: a way of thinking that helps you get more from whatever you have in front of you. Across three live classes and six hours of instruction, you stop watching and start doing, working through hands-on activities that change how you approach an investigation.
It's designed for journalists, lawyers, researchers, and investigators who want a practical, structured introduction to open-source investigation.
Outcomes
- Learn a repeatable method for OSINT investigations
