Visa Expands AI Tool to Automatically Fix Cyber Vulnerabilities

Visa has expanded its AI-driven cyber risk management tool, called the Visa Vulnerability Agentic Harness (VVAH), to go beyond simply detecting security weaknesses. The updated system can now also remediate identified vulnerabilities and validate that the fixes were successful, the company announced in a press release.

VVAH was first launched in June, following Visa's participation in Anthropic's Project Glasswing, an initiative focused on applying advanced AI models to cybersecurity challenges. By automating the full cycle of discovery, repair, and verification, Visa aims to reduce the time it takes to close security gaps that could otherwise be exploited by attackers.

While this development is specific to Visa's own systems and clients, it reflects a broader trend of large organisations using AI to speed up vulnerability management. For small businesses, this signals that AI-assisted security tools are becoming more capable and mainstream, and similar technology may soon be more accessible to smaller organisations through vendors and service providers.
