An Essential
Format: Paperback
I've created PowerPoints for executives in major corporations and national non-profits for years now, and this is one of the first books I suggest anyone who needs to create their own PowerPoint look to. Beyond Bullet points is accessable enough that the novice PowerPoint user can understand what's going on and use the lessons in his or her next presentation; it's also detailed and challenging enough that even an old salt like me can find things to learn and do. Don't be another person who stands on stage reading their PowerPoint, and don't let reading your slides distract the audience from your presentation; follow the suggestions in this book and wow your audience.

This is an invaluable tool for Network Admins.
Format: Paperback
This is a great book for Network Administrators who also have Cybersecurity Training to better protect their networks. I work for a smaller school district and this book has been invaluable.

A must-read for professionals seeking to stay ahead in a rapidly evolving landscape.
Format: Kindle
“ChatGPT for Cybersecurity Cookbook” by Clint Bodungen offers a well-organized, practical deep dive into the integration of generative AI, specifically ChatGPT, within cybersecurity. From the perspective of a cybersecurity professional, this book stands out as a valuable resource for anyone looking to modernize and automate many of the repetitive tasks in cybersecurity, such as threat analysis, vulnerability management, and policy creation.
The book’s greatest strength lies in its focus on practical, actionable “recipes.” Each chapter walks you through real-world use cases for applying ChatGPT to cybersecurity operations. For instance, Bodungen effectively demonstrates how to automate penetration testing and vulnerability assessments using AI-driven techniques, something that can significantly streamline the red team’s workflow . The book’s use of LangChain for parsing and analyzing vulnerability reports, as well as integrating AI for governance, risk, and compliance (GRC) assessments, provides blue teams with a powerful set of tools for enhancing their day-to-day operations .
One of the highlights is how the author tackles threat intelligence, using ChatGPT alongside the MITRE ATT&CK framework, which can help automate complex tasks like identifying and categorizing threat actors and their tactics, techniques, and procedures (TTPs). For any seasoned cybersecurity analyst, this can save a lot of time and reduce human error when managing large volumes of data .
However, it’s important to note that the book assumes a decent understanding of Python and core cybersecurity concepts. It’s not for absolute beginners but provides significant value for professionals looking to integrate AI into their operations more efficiently.

A Career-Changing Read for Cybersecurity Professionals
Format: Paperback
This book completely changed the trajectory of my career. As a self-taught security professional with 30 years of experience, I found myself feeling stagnant and losing interest in cybersecurity. The rapid changes in the field made me question my next steps, and I had zero knowledge of Generative AI, let alone its applications in cybersecurity.
Then, the week this book was released, I bought it—and told no one. It was my personal experiment, a chance to dive into something new. Since then, I’ve read multiple books on Generative AI for Cyber, applied the concepts, and expanded my expertise.
Today, I am considered the SME for Cyber AI in my organization, actively participating in AI working groups, and regularly speaking, mentoring, and presenting on the topic.
In fact, I was the third reviewer of this book (5 stars) and deleted the review after about a week. I didn’t want someone who knew me to connect the review to me and figure out how I got so smart on the topic so quickly. Now, I’m back, giving it the review it truly deserves.
This book reignited my passion for cybersecurity and relaunched my career. If you're in cyber and looking for a way to break through stagnation or explore the future of AI in security, this is the book that could redefine your path—just like it did for me.
