- Level 1 teaches basic OSINT collection and analysis: you'll learn Google Dorking to find hidden web data, retrieve metadata from images and documents, scrape public social media footprints, and use simple OSINT tools; all focused on ethical, repeatable evidence collection.,
 
OSINT - Level 2: https://tryhackme.com/jr/osintledit2
- Level 2 applies OSINT skills to real-world investigations: you’ll learn to document findings clearly, convert collected data into reportable intelligence, verify provenance through cross-referencing and validation, and run structured, repeatable investigation workflows.,
 
OSINT - Level 3:  https://tryhackme.com/jr/osintNEW3-tested
- Level 3 focuses on advanced OSINT methods for cybersecurity, forensics, and intelligence: you’ll learn geolocation workflows and GEOINT techniques, apply OSINT tools for mapping and landmark analysis, understand Personally Identifiable Behavior (PIB) and OPSEC best practices, and implement the Berkeley Protocol to structure high-integrity investigations.
