By applying symbolic execution and the Z3 theorem prover to BPF bytecode, we’ve automated the generation of malware trigger packets, cutting analysis time from hours to seconds.

Recent advances in quantum hardware and software have accelerated the timeline on which quantum attack might happen. Cloudflare is responding by moving our target for full post-quantum security to 2029.

Cloudflare Organizations is now in public beta, introducing a new management layer for enterprise customers with multiple accounts. Learn how we consolidated our authorization systems to enable org-wide management.

The explosion of AI-bot traffic, representing over 10 billion requests per week, has opened up new challenges and opportunities for cache design. We look at some of the ways AI bot traffic differs from humans, how this impacts CDN cache, and some early ideas for how Cloudflare is designing systems to improve the AI and human experience.

Today we are launching the beta of EmDash, a full-stack serverless JavaScript CMS built on Astro 6.0. It combines the features of a traditional CMS with modern security, running plugins in sandboxed Worker isolates.

Eight years ago, we launched 1.1.1.1 to build a faster, more private Internet. Today, we’re sharing the results of our latest independent examination. The result: our privacy protections are working exactly as promised.

Magic Transit customers can now program their own DDoS mitigation logic and deploy it across Cloudflare’s global network. This enables precise, stateful mitigation for custom and proprietary UDP protocols.

We are opening our advanced Client-Side Security tools to all users, featuring a new cascading AI detection system. By combining graph neural networks and LLMs, we've reduced false positives by up to 200x while catching sophisticated zero-day exploits.

Workflows are now visualized via step diagrams in the dashboard. Here’s how we translate your TypeScript code into a visual representation of the workflow.

When we investigated why our Atlantis instance took 30 minutes to restart, we discovered a bottleneck in how Kubernetes handles volume permissions. By adjusting the fsGroupChangePolicy, we reduced restart times to 30 seconds.

We’re introducing Dynamic Workers, which allow you to execute AI-generated code in secure, lightweight isolates. This approach is 100 times faster than traditional containers, enabling millisecond startup times for AI agent sandboxing.

Cloudflare’s Gen 13 servers double our compute throughput by rethinking the balance between cache and cores. Moving to high-core-count AMD EPYC ™ Turin CPUs, we traded large L3 cache for raw compute density. By running our new Rust-based FL2 stack, we completely mitigated the latency penalty to unlock twice the performance.

Cloudflare's Gen 13 servers introduce AMD EPYC™ Turin 9965 processors and a transition to 100 GbE networking to meet growing traffic demands. In this technical deep dive, we explain the engineering rationale behind each major component selection.

Kimi K2.5 is now on Workers AI, helping you power agents entirely on Cloudflare’s Developer Platform. Learn how we optimized our inference stack and reduced inference costs for internal agent use cases.

We are expanding Regional Services with new pre-defined regions and the launch of Custom Regions. Customers can now define precise geographical boundaries for data processing, tailored to meet their compliance and performance needs.

Cloudflare is appealing a €14 million fine from Italian regulators over "Piracy Shield," a system that forces providers to block content without oversight. We are challenging this framework to protect the Internet from disproportionate overblocking and lack of due process.

Learn how Cloudflare and CDW de-risk SASE migrations with a blueprint that treats legacy debt as an application modernization project.

Blocking bots isn’t enough anymore. Cloudflare’s new fraud prevention capabilities — now available in Early Access — help stop account abuse before it starts.

Cloudflare now returns RFC 9457-compliant structured Markdown and JSON error payloads to AI agents, replacing heavyweight HTML pages with machine-readable instructions. This reduces token usage by over 98%, turning brittle parsing into efficient control flow.

Cloudflare AI Security for Apps is now generally available, providing a security layer to discover and protect AI-powered applications, regardless of the model or hosting provider. We are also making AI discovery free for all plans, to help teams find and secure shadow AI deployments.
