A configuration mismatch in GLM 5.3 on Workers AI triggered an SGLang bug that exposed KV cache pages across requests. Here is how we addressed the issue.
Cloudflare has achieved South Korea's ISMS certification following an audit across 80 controls. Learn how we localized user consent flows, adapted social sign-up paths at the edge, and validated our global security program.
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.
Following the discovery that eight eMudhra intermediate certificates use weak keys, Cloudflare is deploying mitigations and releasing client updates. We explain the impact, our response, and what customers and developers should do next.
CVE-2026-88771 lets attackers run commands on NetScaler Gateway before anyone signs in. Patching takes time most teams don't have, so the sign-in decision has to move in front of the vulnerable code.
Identity alone doesn't guarantee a bot will behave responsibly. We are introducing a system to continuously evaluate whether Verified bots honor site preferences, like robots.txt and HTTP 429s, ensuring they remain accountable over time.
Cloudflare Managed Defense uses a team of specialized AI agents built on Workers and global network telemetry to analyze security alerts. By separating deterministic evidence collection from model inference, the system delivers grounded recommendations to Managed Defense Analysts.
Fraudsters are increasingly using AI to bypass stateless security checks. Cloudflare's new Account Abuse Protection dashboard uses stateful analysis and edge-generated Hashed User IDs to help teams investigate and block account abuse.
Quick Tunnels now support email authentication. Add --allowed-mail to one cloudflared command, and only the addresses or domains you list can reach your local app. No Cloudflare account required on either side.
AI sovereignty is not a zero-sum game, but many governments now believe it is. Cloudflare's answer: more local open-source models, model-agnostic security tools, and a commitment to giving nations genuine choice.
We’re building CryptoLabe, an internal AI-powered tool that discovers cryptography across our codebase, surfaces dependencies, and helps us progress toward a full post-quantum migration by 2029. Here’s what we’ve learned so far.
Twelve years after launching Universal SSL, Cloudflare is applying to become a certificate authority. By combining an established root, an ACME-first approach, and Merkle Tree Certificates, we are building a post-quantum CA for the open web.
As post-quantum signatures threaten to inflate TLS handshakes and certificate transparency logs, Merkle Tree Certificates offer a path to compact, auditable authentication. Cloudflare’s new certificate authority will support MTC issuance at scale.
We are expanding access to Cloudforce One's Threat Events Platform to every Cloudflare account and introducing Threat Signals. Threat Signals automatically parses open-source threat reporting, extracts structured indicators, and connects threat context directly to your WAF rules.
Cloudflare has added visibility into post-quantum (PQ) encryption in TLS 1.3 directly into HTTP Analytics, Log Explorer, and Logpush. Learn how to make sure your domain is protected with PQ encryption.
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.
Misconfiguring Turnstile by skipping backend validation leaves sites exposed to bots. Turnstile Spin fixes incomplete setups by using your preferred AI coding agent to wire up server-side verification.
