Zero Wire on Cloudflare Radar pairs plain-language briefings with global attack telemetry and remediation steps. Triage critical CVEs faster and decide how to protect your infrastructure.
Cloudflare's web application firewall can now correlate an HTTP request with its response. Full transaction detection helps every customer find successful exploits, data exposure, and risky misconfigurations that request-only inspection can miss.
Cloudflare has deployed default web application firewall (WAF) protections for newly disclosed PHP vulnerabilities before public disclosure. The rules use request and response signals to stop exploit attempts and prevent exposed data from reaching attackers.
Cloudflare introduces an adaptive security framework connecting risk discovery, agent governance, runtime protection, and AI-powered response in a continuous learning loop.
We built a WAF tester that adapted each request based on what the WAF blocked or passed. This helped us explore variations that a fixed test might miss. We ran it across six attack categories on an authorized staging environment and discovered detection gaps worth fixing. Here’s how the loop worked, what got through, and what we did about it.
Cloudflare learns the structure of your HTTP requests and identifies deviations. You can add a positive security layer that helps reduce attack surface as AI makes it easier for attackers to generate and vary payloads.
Cloudflare has deployed two WAF rules in response to high-severity vulnerabilities disclosed to us by the WordPress security team. The new rules protect all Cloudflare customers using affected WordPress versions, but customers should still update immediately to a patched release
Cloudflare is introducing Attack Signature Detection and Full-Transaction Detection to provide continuous, high-fidelity security insights without the manual tuning of traditional WAFs. By correlating request payloads with server responses, we can now identify successful exploits and data exfiltration while minimizing false positives.
Cloudflare offers protection against a new high profile vulnerability for React Server Components: CVE-2025-55182. All WAF customers are automatically protected as long as the WAF is deployed.
