Best Systems Engineering Experts

For over 20 years, I've been on the front lines of cybersecurity, working with global organisations to help them answer critical questions like: "How effective are our security measures against a cyber attack?" My passion is empowering companies to identify and fortify their attack surface. I help leadership teams evaluate their security stack's effectiveness and build actionable roadmaps. Some of the topics I cover are Enterprise cybersecurity and strategy, culture and how it impacts cyber resilience. Emerging attacks and attacker innovation in ransomware and increasingly AI security risks. This passion for sharing actionable knowledge is why I also started writing my blog. It's my way of sharing ideas and providing insights for enterprise security defenders and educate the wider community. In my day-to-day role at Pentera, I lead a team of talented security engineers. We partner with leading organisations who are ready to embrace change. As a speaker and mentor, I enjoy challenging the norms, introducing disruptive technologies, and sharing best practices to raise the bar.
