Cloudflare Uses OpenAI Daybreak to Hunt and Fix Vulnerabilities

Cloudflare’s security team has announced that it used OpenAI’s Daybreak platform to scan its code base and infrastructure for vulnerabilities. Daybreak’s generative‑AI engine combed through thousands of configuration files and code snippets, flagging potential weaknesses that might otherwise slip through manual reviews.

Once the issues were identified, Cloudflare developers turned to Codex to help write and audit patches. Codex’s ability to understand context and suggest cleaner, more efficient code meant the team could fix problems faster while also tightening overall code quality.

The company plans to publish the generated fixes for community review and will integrate the AI workflow into its ongoing security operations. By automating both discovery and remediation, Cloudflare demonstrates how generative AI can accelerate the entire vulnerability‑management cycle.

This announcement follows Cloudflare’s expanding partnership with OpenAI and underscores a broader industry shift toward using AI tools to enhance cyber‑defense capabilities.
