The survey of thousands of security leaders exposes an underlying naivete about AI-built code and its vulnerabilities, even as tools like Anthropic’s Mythos are uncovering security flaws orders of magnitude faster than any human security team could ever hope to.
“Mythos-class models collapse the window between a vulnerability existing and a working exploit being available from months to minutes,” the report notes. Enterprises relying on traditional security tools and methods, it says, “cannot survive this reality.”
Security as an afterthought
Checkmarx’s survey of 2,350 CISOs, AppSec managers, and developers across 14 countries focused on how much AI-developed code enterprises are deploying, the vulnerabilities it introduces, how it impacts developer workflows, and overall sentiment about AI code and security posture.
Today, nearly half of production code is AI-generated, and the majority of enterprises also report that at least half their codebase is made up of open-source components, according to the report.
