The best problem-solving writing in software engineering — databases, performance, security, frontend and distributed systems, in one feed.
BotID Deep Analysis is a sophisticated, invisible bot detection product. This article is about how BotID Deep Analysis adapted to a novel attack in real time, and successfully classified sessions that would have slipped through other services.
As AI agents change how the Internet is used, they create a challenge for security. We explore how Anonymous Credentials can rate limit agent traffic and block abuse without tracking users or compromising their privacy.
We propose an open registry format for Web Bot Auth to move beyond IP-based identity. This allows any origin to discover and verify cryptographic keys for bots, fostering a decentralized and more trustworthy ecosystem.
The world is adopting anonymous credentials for digital privacy, but these systems are vulnerable to quantum computers. This post explores the cryptographic challenges and promising research paths toward building new, quantum-resistant credentials from the ground up.
Figma has acquired Weavy, a platform that brings generative AI and professional editing tools into the open canvas.
Take a look inside our automated pipeline for rapid, rigorous evaluation for the GitHub MCP Server.
Many products at Cloudflare aren’t possible without pushing the limits of network hardware and software to deliver improved performance, increased efficiency, or novel capabilities such as soft-unicast, our method for sharing IP subnets across data centers. Happily, most people do not need to know the intricacies of how your operating system handles network and Internet access in general. Yes, eve
Researchers and practitioners have been studying connections almost as long as the Internet that supports them. Today, Cloudflare’s global network receives millions of connections per second. We explore various characteristics of TCP connections, including lifetimes, sizes, and more.
IPv4 scarcity drives widespread use of Carrier-Grade Network Address Translation, a practice in ISPs and mobile networks that places many users behind each IP address, along with their collected activity and volumes of traffic. We introduce the method we’ve developed to detect large-scale IP sharing globally and mitigate the issues that result.
Cloudflare mitigated a 12-hour DDoS attack against Moldova's Central Election Commission, blocking over 898 million malicious requests that peaked at 324,333 requests per second. This defense kept critical election infrastructure online and accessible for citizens during a critical parliamentary vote.
We identified and patched two DDoS vulnerabilities in our QUIC implementation related to packet acknowledgements. Cloudflare customers were not affected. We examine the "Optimistic ACK" attack vector and our solution, which dynamically skips packet numbers to validate client behavior.
On mobile, people can lose their sense of context and can’t easily tell where a section begins or ends. Good small-screen design can help orient them using a variety of techniques.
Get ahead in PostgreSQL and GIS: On-Site, Online or in your Office. You decide what is best for you and your Team.
Vercel has achieved TISAX Assessment Level 2 security standard to align with automotive and manufacturing industries
Cloudflare Workers' support for automatic tracing is now in open beta! Export traces to any OpenTelemetry-compatible provider for deeper application observability -- no code changes required
Today over half of human-initiated traffic with Cloudflare is protected against harvest-now/decrypt-later with post-quantum encryption. What once was a cool science project, is the new security baseline for the Internet. We’re not done yet: in this blog post we’ll take measure where we are, what we expect for the coming years, and what you can do today.
Cloudflare is launching an experiment with Chrome to evaluate fast, scalable, and quantum-ready Merkle Tree Certificates, all without degrading performance or changing WebPKI trust relationships.
In Q3 2025, global Internet disruptions were caused by everything from government shutdowns to stray bullets and earthquakes. This report analyzes the traffic data behind these outages to show their real-world impact on connectivity.
We present a data-driven framework to quantify cross-layer Internet resilience. We also share a list of measurements with which to quantify facets of Internet resilience for geographical areas.
This blog describes what we can expect from CYBERTEC in future. Dive in and hear it for the CEO himself, and know about his thoughts.
As AI accelerates product development, design systems keep the bar for craft and quality high. Here’s everything we announced at Schema to help teams design for the AI era.
Agentic AI systems present unique security challenges. The fundamental security weakness of LLMs is that there is no rigorous way to separate instructions from data, so anything they read is potentially an instruction. This leads to the “Lethal Trifecta”: sensitive data, untrusted content, and external communication - the risk that the LLM will read hidden instructions that leak sensitive data to
At Universe 2025, GitHub’s next evolution introduces a single, unified workflow for developers to be able to orchestrate any agent, any time, anywhere.
In this year’s Octoverse, we uncover how AI, agents, and typed languages are driving the biggest shifts in software development in more than a decade.
