About Charlie Su
Building a more secure future for AI
I build secure AI systems. As a former CISO, I've spent over a decade protecting organizations from evolving threats. When AI adoption started accelerating, I saw a familiar pattern: companies rushing to adopt new technology without considering the security implications.
The difference this time? AI systems can be more complex, more interconnected, and more consequential than anything we've seen before. A single vulnerability doesn't just expose data—it can compromise the integrity of autonomous decisions affecting millions of people.
That realization led me to create TopFlow and dedicate my practice to AI security. Today, I work with security teams and enterprises, helping them build AI systems that are secure by design, compliant by default, and resilient against emerging threats.
