Steven Harris brings the mindset of a detective and the precision of a threat analyst to every class he teaches. As a Certified Instructor for the SANS Institute, he leads SEC497: Practical Open-Source Intelligence (OSINT) and SEC587: Advanced Open-Source Intelligence (OSINT) Gathering and Analysis, helping students move beyond data collection to uncover hidden narratives behind digital footprints—and leave class confident investigating real-world targets with ethical, professional precision. In his day role as a Cyber Threat Analyst at Protection Group International (PGI), Steven deploys the same tradecraft he teaches—tracking adversaries and advising organizations on how to stay ahead. His mission is to make OSINT practical and empowering—helping students see how open-source data protects people, organizations, and national interests.
