Organizations must secure transactions while adapting to faster, more complex threats, said Subra Kumaraswamy, CISO at Visa. See Also: How Unstructured Data Chaos Undermines AI Success AI has long supported cybersecurity and fraud detection, but generative AI has significantly changed the threat landscape. Attackers now scale operations, automate discovery of vulnerabilities and launch exploits with greater speed. Autonomous agents amplify this shift by executing attacks without human input. "What has changed the last three years since ChatGPT is the notion of Gen AI and how that is creating whole different dynamics for both the bad actors, the attackers and the good guys - the defenders. So, the way I see it is that AI is enabling the bad actors at scale," Kumaraswamy said. Defenders must respond with equal speed and intelligence. AI-driven security operations help detect threats, automate response and shift focus toward proactive threat hunting. At the same time, organizations must build trust in AI-driven commerce, where agents act on behalf of users within defined guardrails, he said. In this video interview with Information Security Media Group at RSAC Conference 2026, Kumaraswamy also discussed: How AI enables attackers to scale fraud and exploit vulnerabilities faster; How autonomous agents expand risk across transactions and systems; AI benefits in threat detection, response and proactive defense. Kumaraswamy leads Visa's cybersecurity, technology controls and cyber resilience functions. He brings more than 30 years of security leadership experience, with prior roles at Apigee, Intuit, eBay and Sun Microsystems, and deep expertise in Zero Trust, authentication and cloud security.
