As an OSINT professional, I'm always looking to learn new tricks of the trade. This book not only showed me new pivots I can use in my investigations, but also explained every topic in an easy-to-understand way. Deep Dive is definitely a good entry book into OSINT, and also a great read for subject matter experts and everyone in between. One of the best parts about this book is that it doesn't focus on tools, which can become outdated, but more on critical thinking and which questions to ask to get the answers you're seeking. The use of cases and examples makes every topic come together neatly. You can tell Rae put her heart and a lot of passion into writing this. I will be recommending this book to all of my mentees.

As both an OSINT instructor and practitioner, this is the book I can easily recommend to new OSINT analysts just starting out, or give to those who may need a refresher in specific subject area. Rae thought of everything and set it out from the very beginning. She didn't wait until the end to discuss critical thinking, bias, or ethics. These are fundamental and should be discussed early and often. And, because this book is more about methodology than a running list of resources, she made sure to include OPSEC at every turn to ensure the integrity, safety and security of one's research. For those in the OSINT community, this is the page turner you've been waiting for.

I feel like my life is nothing but reading cybersecurity books and articles so it was an honest pleasure to sit down with Rae Baker's book and found it both informative and entertaining. If you are a beginner in the world of Open Source Intelligence you will find this book perfect tutor for learning the field from the ground up if you have mastered OSINT (unlikely..lol) you will find the book a great resource.

This is a useful desk reference for CyberSec professionals. The material in digital artifacts and detailed information on non traditional intelligence tradecraft is useful in the knowledge domains of maritime intelligence ,HUMINT, IoT, cyber physical systems and promises/threats of OSINT.

Well crafted book. I highly recommend this resource.

I read the book and I can say that I really liked the way that the content was structured Definitely is a book worth buying and gave me a lot of different approaches for an OSINT Investigation, especially in the transportation section! Nice and easy to read, although I would prefer having more links and more real world investigations to follow up the context of the book (that's why I left 4-stars).

I love the way this book doesn’t make any assumptions about past knowledge and is very well cited. Enjoy this book if you’re curious about diving into OSINT or to update your knowledge as an experienced investigator.

owning a company that does Cyber Intelligence work, this book is a treasure trove of information. I would highly recommend it to anyone in the business or just want to know what the world does that now one sees.

This book is a fantastic resource for anyone interested in conducting OSINT investigations and anyone who involved in OSINT investigations.

Very insightful and helped me expand my own knowledge of OSINT. The author did a fantastic job of breaking down the procedures of an OSINT investigation throughout the entirety of the book. Awesome work, Rae!

An informative book about open source intelligence.

Amazingly deep theory on all ranges of OSINT technologies, theory, and applications.

Libro interesante sobre OSINT.

Ofrece mucha información, pero advierto que algunas de las herramientas que se mencionan funcionan dentro de determinados países, en su mayor parte angloparlantes.

En líneas generales me parece un buen libro

Great book

Excellent content but arrived damaged.
