Cloudflare integrates OpenAI Daybreak and Codex for vulnerability discovery and developer productivity

Details

Cloudflare launched Vulnerability Discovery and Remediation, an early-access service that uses OpenAI models via Daybreak to investigate code and propose fixes for customer review.
The service connects source code vulnerabilities to live production traffic and security signals to prioritize findings and prepare proposed mitigations.
A Cloudflare team of four developers rebuilt a postponed product in 3 days using Codex, spending $1,100 on tokens, a task estimated to require 10x more developers and months of sequencing manually.
100% of Cloudflare's software developers use Codex to increase output and improve code quality.
The service is offered through Cloudflare Managed Defense and requires customer authorization to investigate code.
Proposed patches and web application firewall rules undergo automated checks and internal review before being shared with customers.
