Frequently Asked Questions

What is the best OSINT book?

The best OSINT book is the one most relevant to you. Open-Source Intelligence is a broad field, and you should choose learning materials accordingly. Investigations are conducted differently by various professionals. For example, pentesters follow a different methodology than journalists. The former may appreciate a practical book on network scanning and vulnerability analysis, whereas journalists would typically prefer fact-checking and geolocation guides. Choose a book that aligns with your personal goals.

How do I choose the right book for me?

If you're a beginner, start with Open Source Intelligence Techniques by Michael Bazzell or Deep Dive by Rae Baker. Rae does a great job of explaining investigative methodology in simple terms and shares practical OSINT techniques. Michael Bazzell’s book focuses more on tools and OSINT tactics. Both books are great for beginners. For advanced practitioners, books that cover specialized tools and methodologies may be more suitable. Consider reading reviews and recommendations on Amazon to make a more informed decision.
