Cisco and OpenAI redefine enterprise engineering with Codex
cisco integrated openai's codex to build ai defense, saving 1,500 engineering hours monthly and increasing defect resolution throughput 10-15x.
cisco collaborated with openai to integrate codex into its complex, c/c++-heavy codebases, transforming it from a productivity tool into an autonomous engineering teammate capable of cross-repository reasoning and cli-based compile-test-fix loops. this agentic workflow enabled cisco to write the majority of its new ai defense product, reduce build times by 20% across 15 interconnected repositories, and automate large-scale framework migrations from react 18 to 19. these implementations compressed critical engineering work from several quarters to weeks while maintaining strict security and governance standards.
