Visa Unveils New AI Cybersecurity Tools to Speed Vulnerability Fixes

Visa expanded its cybersecurity portfolio with an updated open-source framework and new advisory services aimed at helping organizations find and fix vulnerabilities faster, the company said in a press release.

The latest version of the Visa Vulnerability Agentic Harness (VVAH), an open-source, model-agnostic framework, extends its workflow from discovery to validated remediation. Visa said the tool can reduce the Mean Time to Adapt (MTTA), the interval between identifying an attack path and resolving it, from weeks to hours.

Visa Consulting & Analytics introduced three new cybersecurity advisory services designed to help clients assess risk and prioritize remediation efforts in a changing threat environment, the release said.

"Across Asia Pacific, AI is accelerating both the scale of cyber threats and the speed at which vulnerabilities can be exploited," said Prateek Sanghi, Head of Visa Consulting & Analytics, Asia Pacific. "The real challenge is determining which risks matter most and remediating them before they can be leveraged by attackers."

CAIXA Cartões, a Brazilian card issuer, worked with Visa on a cybersecurity maturity assessment. "Our partnership with Visa has helped broaden our strategic perspective on cybersecurity," said Lessandro Thomaz, Executive Director at CAIXA Cartões.

VVAH was originally released after Visa's participation in Anthropic's Project Glasswing, a frontier AI cybersecurity initiative. Since its open-source release in June 2026, the framework has been downloaded tens of thousands of times, Visa said. The company also joined NVIDIA's Open Secure AI Alliance and IBM and Red Hat's Project Lightwell initiative to help secure open-source software.
