Visa has released its AI-powered cyber defense system as open source after security vulnerabilities were found in it. The move lets outside researchers and developers inspect the code, report flaws and help harden the tool. It is a notable step for a payments company, since firms usually keep security tooling internal, and it signals growing industry reliance on AI for fraud and threat defense.
