How Cisco ships AI-generated code at scale

Cisco ships AI-generated code at scale—without breaking trust.

Thousands of engineers. An exponential surge of AI-written code. One rule: every line gets verified before it hits a pull request.

That's why Cisco made SonarQube their centralized verification layer.

"Quality used to be table stakes. We've turned it into an engineering accelerator." — Stephen Byrnes, Distinguished Engineer, Cisco

The results

  • 27,000 issues fixed in 3 months—technical debt zero
  • Up to 3x productivity gains, with defect density down
  • Review bottleneck cleared, senior engineers unblocked


Verification is the foundation of scalable AI engineering.
