Visa Releases AI-Powered Cybersecurity Tool as Open-Source Software

Visa has released an AI-powered cybersecurity tool as open-source software, allowing security teams to find and fix software flaws more efficiently. The Vulnerability Agentic Harness maps code, directs multiple AI models, and ranks vulnerabilities so teams can tackle the biggest threats first.

The tool supports repairs and checks whether fixes work, with human review at key stages. This move is central to Visa's business, as keeping payments flowing safely is crucial to its operations.

By opening up the code, Visa may attract more testing and improvements from outside developers. However, rivals can access the tool, but copying software does not recreate Visa's network, operating experience, or security expertise.

The share price of $360.05 sits 11.2% below the GF Value estimate of $405.48, suggesting potential upside against the model's benchmark.
