Jimmy Mesta is the co-founder and CTO at RAD Security, where he leads the technical direction of the company’s platform. He has spent much of his career in security engineering, with experience spanning application security, cloud-native security, containerization, and large-scale cloud security programs. Before RAD Security, he worked as an independent consultant helping organizations build security programs and protect complex, containerized environments, and he has also led technical security training and research efforts.
In this episode, Jimmy talks about how cybersecurity has changed along with the rise of cloud systems and AI. He explains that security teams are now dealing with problems that move too fast and at too large a scale for older, signature-based tools to handle well. For him, that means AI is becoming part of the operating model for security, especially when it comes to sorting alerts, handling repetitive work, and helping teams keep up with constant change in code and infrastructure. He is realistic about AI’s flaws, including mistakes and unpredictable output, but says human teams have limits too, like fatigue and information overload. His view is that security work should shift toward stronger systems, better data, and more human judgment in the areas where people add the most value.
