And finally, if you're ready to really become an expert on the topic, check out SEC487: Open-Source Intelligence (OSINT) Gathering and Analysis

This is a foundational course in open-source intelligence (OSINT) gathering and, as such, will move quickly through many areas of the field. While the course is an entry point for people wanting to learn about OSINT, the concepts and tools taught are far from basic. The goal is to provide the OSINT groundwork knowledge for students to be successful in their fields, whether they are cyber defenders, threat intelligence analysts, private investigators, insurance claims investigators, intelligence analysts, law enforcement personnel, or just someone curious about OSINT. 

“The topics covered in SEC487 were incredibly broad within the OSINT analysis field and opened my eyes to capabilities and tools I did not know existed.” – Daniel R

"SEC487 continues to introduce exciting and relevant data. Each day we dug deeper into techniques and learned about additional resources that can be used to do day-to-day OSINT work." - David U.
