TL;DR AI
2 min readKey summary
Visa launched an open-source agentic AI security harness that can detect vulnerabilities, generate patches, and validate them with adversarial testing.
The tool is designed to accelerate remediation after flaws are found, with changes enabled by default for production code unless an operator restricts it.
The launch signals a move beyond AI-assisted detection toward automated remediation, while raising governance questions over how much authority coding agents should receive.
