Cloudflare Zero Wire

What it is

Zero Wire is a public vulnerability intelligence feed on Cloudflare Radar, launched on 3 November 2026. It is part of Cloudflare's Radar security section. Each briefing gives a plain-language explanation of a significant vulnerability, who should investigate, recommended actions, and links to evidence and vendor guidance. Cloudflare states the information is useful whether or not you are a Cloudflare customer.

What it helps with

- Reading plain-language briefings on critical CVEs in internet-facing software, runtimes, and libraries
- Separating issues that need attention from reference items whose guidance has stabilized
- Turning a disclosure into next steps such as identifying affected deployments, applying vendor updates, or keeping compensating controls in place
- Using a pre-compiled prompt from Cloudflare with an AI agent to assess impact on your own infrastructure
- Following linked vendor advisories and, when applicable, Cloudflare protection guidance such as WAF configuration

Who it's for

Security leaders, CISOs, and practitioners who need a clear starting point when a critical internet-facing vulnerability is disclosed, including teams that do not use Cloudflare products.

Worth knowing

Zero Wire covers only significant issues that security teams need to assess. Briefings link out to the vendor's own advisory, so check that for the authoritative fix.

Is Zero Wire the same as a CVE database like NVD?
No. Cloudflare positions it as briefings that complement vendor advisories and vulnerability databases, not as a full catalog of every CVE.

Do I need a Cloudflare account?
No. The launch post says the information is useful whether or not you are a Cloudflare customer, and the feed is published on public Cloudflare Radar.

How does it relate to Cloudflare, AlienVault OTX, and Recorded Future?
Zero Wire sits inside Cloudflare as a Radar security feed. In our view AlienVault OTX and Recorded Future are broader threat intelligence platforms, while Zero Wire is a focused public briefing wire for critical internet-facing vulnerabilities.
