Visa Expands AI Cybersecurity Tools with Vulnerability Harness Update
Visa's VVAH framework now extends from vulnerability discovery to validated remediation, with some fixes shrinking from weeks to hours. The company also launched three new advisory services.
Visa (NYSE: V) updated its open-source cybersecurity framework, the Visa Vulnerability Agentic Harness, to move beyond vulnerability discovery into automated remediation and validation. The new release, announced Wednesday, builds on the company's participation in Anthropic's Project Glasswing, a frontier AI security initiative.
The framework, model-agnostic and available on GitHub, is designed to help organizations cut the Mean Time to Adapt, the gap between finding a vulnerability and fixing it, from weeks to hours, Visa said.
To help clients act on the findings, Visa Consulting & Analytics introduced three new cybersecurity advisory services. These are informed by Visa's internal experience running AI-powered security at scale, the company 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 for Asia Pacific. "Identifying vulnerabilities is no longer the differentiator. The real challenge is determining which risks matter most and remediating them before they can be leveraged by attackers."
Sanghi said the shift in focus from the number of vulnerabilities identified to the Mean Time to Adapt has become more critical than ever.
Visa also highlighted a client engagement with CAIXA Cartões, the Brazilian card issuer. "At CAIXA, we understand that cybersecurity is a fundamental pillar for customer trust and business sustainability in an increasingly complex digital environment," said Lessandro Thomaz, executive director at CAIXA Cartões. He said the partnership with Visa helped broaden the issuer's strategic perspective on cybersecurity.
Since the VVAH framework was released as an open-source project in June 2026, it has been downloaded by tens of thousands of developers globally, Visa said. The company also joined NVIDIA's Open Secure AI Alliance and IBM and Red Hat's Project Lightwell, both aimed at securing open-source software and AI infrastructure.
