Cloudflare Launches Zero Wire Threat Intelligence Service Targeting Internet-Facing Vulnerabilities

Internet infrastructure and security firm Cloudflare recently introduced Zero Wire, a public vulnerability intelligence service hosted on its Cloudflare Radar platform and accessible to non-customers. Rather than archiving all CVEs, Zero Wire curates major vulnerabilities in internet-facing software—including web applications, runtimes, and libraries—with a focus on flaws whose risks can be mitigated via proxy server defenses. The service outlines affected systems, exploitation evidence, remediation guidance, vendor advisories, and relevant research. For selected flaws, Zero Wire displays WAF mitigation details and observed HTTP traffic matching specific WAF rules; Cloudflare emphasizes that WAF mitigations cannot substitute for patching and observed traffic does not prove successful compromise or damage scale. Additionally, Zero Wire provides AI agent evaluation prompts, enabling organizations to task AI agents with read-only audits of internal software and defense status without triggering automated scans or system modifications.

Key takeaways

• Cloudflare rolled out Zero Wire, a publicly accessible vulnerability intelligence service on Cloudflare Radar.
• The service curates critical vulnerabilities in web applications and runtimes, offering remediation guides and mitigation data.
• It displays observed HTTP traffic trends matching specific WAF rules, though Cloudflare notes this does not replace patching or verify attack success.
• Zero Wire offers read-only AI agent prompts to assist organizations in auditing system exposure without auto-scanning or altering configurations.
