We are a group of current and former CISOs and security experts who have spent our careers responding to real compromises, studying how attackers operate, and understanding which tactics are actually used in the wild. Because we have seen the impact of different attack vectors firsthand, we want to offer guidance that matches reality—advice that is proportional to both the likelihood and the potential harm of various threats, not shaped by myths or dramatic exceptions. Our goal is to help people focus their time and attention on what truly keeps them safe.
