I am thrilled to write a testimonial for Arnaud, a former staff member who worked for me. He consistently impressed me with his work ethic, creative problem-solving skills, and dedication to his team and job. I am not surprised to see Arnaud continue to excel in his endeavors. This book is a testament to his intelligence, creativity, and perseverance, and I have no doubt that it will be well received by readers. I am proud to have had the opportunity to work with Arnaud and to witness his growth and success.

In today’s world, cybersecurity is no longer a niche topic. It is a crucial aspect of doing business, and the implications of not having a solid security strategy are far-reaching. The Book on Cybersecurity is an excellent resource for demystifying this important topic.

I worked with Arnaud when he was CISO at TNT. Arnaud is a thought leader in the world of cybersecurity. He brings a wealth of knowledge and experience and has a proven track record of success as a CISO.

I found The Book on Cybersecurity to be engaging, with language that is clear, concise, and easy to follow. I particularly appreciate the practical tips and insights provided throughout the book. After reading the first few chapters, I was inspired to immediately fix a few things on my phone.
What really sets this book apart is how engaging and enlightening it is. I didn’t expect to enjoy a book on cybersecurity as much as I did. I would highly recommend it to anyone who is interested in learning more about cybersecurity, regardless of their technical background.
