As both a former CISO and current CEO, I wish I'd had this book early in my career. Keren cuts through the noise to deliver what security leadership actually requires: practical frameworks forged through real failures and hard-won successes. This isn't theory—it's battle-tested wisdom that will make you more effective from day one.

I've known and admired Assaf for years. What makes this book so powerful is that it's not theory – it's hard-won lessons from someone who has built, rebuilt, and led security at the very top. Any current or aspiring security leader will walk away with practical insights they can apply immediately.

Building and sustaining security in major enterprises is much more than a technical discipline. Rather, it's an intense leadership challenge balancing influence, grit and team building.

As a journalist who has covered cybersecurity, I expected the book to be a technical deep dive. Instead, it highlights just how much of the job comes down to judgment and people skills, while still giving a strong dose of practical advice professionals can bring to the job.
