Standing up for the open Internet: why we appealed Italy's "Piracy Shield" fine

At Cloudflare, our mission is to help build a better Internet. Usually, that means rolling out new services to our millions of users or defending the web against the world’s largest cyber attacks.

Announcing Cloudflare Account Abuse Protection: prevent fraudulent attacks from bots and humans

Today, Cloudflare is introducing a new suite of fraud prevention capabilities designed to stop account abuse before it starts.

Complexity is a choice. SASE migrations shouldn't take years.

For years, the cybersecurity industry has accepted a grim reality: migrating to a zero trust architecture is a marathon of misery. CIOs have been conditioned to expect multi-year deployment timelines, characterized by turning screws, manual configurations, and the relentless care and feeding of legacy SASE vendors.

Active defense: introducing a stateful vulnerability scanner for APIs

Security is traditionally a game of defense. You build walls, set up gates, and write rules to block traffic that looks suspicious. For years, Cloudflare has been a leader in this space: our Application Security platform is designed to catch attacks in flight, dropping malicious requests at the edge before they ever reach your origin. But for API security, defensive posturing isn’t enough. That’s why today, we are launching the beta of Cloudflare’s Web and API Vulnerability Scanner.

Fixing request smuggling vulnerabilities in Pingora OSS deployments

In December 2025, Cloudflare received reports of HTTP/1.x request smuggling vulnerabilities in the Pingora open source framework when Pingora is used to build an ingress proxy.

These issues were responsibly reported to us by Rajat Raghav (xclow3n) through our Bug Bounty Program.

From the endpoint to the prompt: a unified data security vision in Cloudflare One

Cloudflare One has grown a lot over the years. What started with securing traffic at the network now spans the endpoint and SaaS applications – because that’s where work happens. But as the market has evolved, the core mission has become clear: data security is enterprise security. Here’s why. We don’t enforce controls just to enforce controls.
