Introducing context-aware vulnerability discovery and remediation with Cloudflare Managed Defense and OpenAI Daybreak models

Your scanner just flagged 4,000 new vulnerabilities, 78 of them critical. Which one do you fix first?

To answer that question, Cloudflare is announcing early access to Vulnerability Discovery and Remediation, now part of Cloudflare Managed Defense. Vulnerability Discovery and Remediation is a new, invitation-only Cloudflare service that helps customers detect and mitigate vulnerabilities in their codebases.

Through the OpenAI Daybreak Defense Network, we use OpenAI Daybreak models, including GPT-5.6 Cyber, for reconnaissance, hunting, and validation against codebases that you authorize us to access. If we detect a vulnerability, we will then propose solutions to you, automatically checking each proposed patch and any accompanying proposed mitigation before presenting them for review. Importantly, you are in the driver’s seat: while we may propose code patches and other mitigations, you decide whether they are implemented.

Choosing what to fix first has always been hard. It's getting harder. Large language models can now surface weaknesses across a codebase in minutes, which means the number of findings keeps climbing. But the real problem is speed. Attackers can use AI to accelerate parts of vulnerability discovery and exploitation, giving security teams and developers less time to decide what matters and act on it.

Imagine that your scanner tells you there's a vulnerability in a handler. It doesn't tell you whether that code is deployed. It doesn't tell you whether anyone is actually hitting that route, what security activity surrounds it, or what controls you already have in place. You have to prioritize the finding without evidence of its production exposure or the protections already in place.
