AI has enabled employees across every team to build applications faster than ever before. But that speed is also what's keeping every CISO up at night: any employee can build an application, deploy it to the public Internet, and accidentally expose internal work or company data. Today, we're launching new tools to make it easy to keep your applications hosted on Workers private.

Most companies designed their resource permissions with a human user in mind. A senior engineer may be able to deploy to production, query a sensitive database, or revoke another user's access. Those privileges come with risk, but that risk has traditionally been bounded by two assumptions: the engineer will use human judgment, and the engineer can only act at human speed.

Since we launched Certificate Transparency Monitoring in public beta in 2019, we've been emailing subscribers whenever a new TLS certificate appears in a public Certificate Transparency (CT) log for one of their domains. Today, it's turned on for more than 650,000 customer domains. It's an early warning that someone, somewhere, has issued a certificate for a hostname in your zone, giving you a chance to spot a mis-issued certificate early.

Welcome to the 25th edition of Cloudflare's DDoS Threat Report. This is the first half-year edition in the series: rather than publishing separate reports for the first and second quarters of 2026, we have combined our coverage of Q1 and Q2 into a single volume covering January through June 2026.

We believe the Internet must be a force for good, and that it requires a foundation of trust. Nowhere is that trust more critical than in public service. Government agencies are the stewards of a nation’s most sensitive data. They protect national security, critical infrastructure, and the personal information of every citizen. Cloudflare’s mission is to help build a better Internet.

The Internet isn’t a single lane of traffic. For a long time, the rule of thumb in web security was that bots are bad, while humans are good. Of course, we’re far past this generalization. Humans can be fraudulent, and bots can be helpful at different levels. Site owners actively want some automated traffic to interact with our sites to make the Internet functional and discoverable. To complicate things further, the line between "human" and "bot" is blurring more and more.

Today, we’re excited to announce a few developer experience improvements to Cloudflare AI Search to make it easy to manage a search solution out of the box. Previously, you had to stitch together components of the Cloudflare primitives (Workers AI, AI Gateway, Vectorize, R2, Browser Run) but now, AI Search can do this automatically, and better. Our goal is to give your agents their own search engine, where they can easily find data to provide better answers for themselves and their humans.

Last year, we enabled Media over QUIC (MoQ) on every Cloudflare server and opened the network for anyone to test. It provided a global MoQ endpoint, but not the isolation and access controls needed to run an application. Today, we’re adding those isolation and access controls. The new MoQ provisioning API lets you create an isolated relay for your application and issue separate credentials for publishers and subscribers.

Cloudflare's Authenticated Origin Pulls and Custom Origin Trust Store now support post-quantum authentication. Here we’ll explain how you can configure fully post-quantum secure mutually authenticated TLS connections to your origin server, dive into the engineering details of how we built it, make a shameful confession, and finally explain how this work fits into our overall post-quantum migration roadmap.

Like most infrastructure, the Internet's fragility is easy to overlook — as long as it's working. When it fails, its complexity comes into full view. Cloudflare is in a unique position to detect and document the moments when one of the interrelated systems the Internet depends on breaks down and connectivity suffers as a result. Each quarter, we summarize the disruptions we detect and annotate on Cloudflare Radar.

How does your computer actually find data? JQ Lau from Cloudflare's hardware team explains the difference between CPU cache and memory with a simple analogy — and why it matters when you're designing servers for millions of requests.

In this episode of This Week in NET, JQ Lau and Victor Hwang from our Network & Infrastructure Strategy team walk us through Cloudflare's 13th generation of servers — the machines that power a significant part of the internet across 330+ cities worldwide. The Gen 13 program doubled compute density by jumping from 96 to 192 cores, but that came with an 83% drop in L3 cache. The team explains how a bold hardware bet, combined with Cloudflare's FL2 Rust-based software rewrite, turned that trade-off into a win across throughput, latency, and power efficiency.

The conversation explores why the Internet and the cloud were not designed for an AI-agent world, and what infrastructure needs to change as software agents begin generating code, running workflows, and interacting directly with online services. Ming and Anni walk through several announcements from Cloudflare’s Agents Week, including new tools for agent infrastructure, memory, developer workflows, AI Gateway, email, artifacts, browser automation, security, and agent-ready websites.

What happens to Internet security when quantum computers become powerful enough to break today’s encryption? In this clip from a full conversation on This Week in NET, Sharon Goldberg explains why researchers and companies are preparing for post-quantum cryptography, what could be at risk if current encryption is broken, and why the timeline may be closer than many expected. This clip is from the This Week in NET podcast about the future of encryption, quantum computing, and post-quantum cryptography.

In this World Quantum Day special edition of This Week in NET, host João Tomé is joined by Bas Westerbaan (Principal Research Engineer) and Sharon Goldberg (Senior Director, Product) to explain why the timeline for post-quantum cryptography may be arriving sooner than expected. Recent research suggests the number of qubits required to break today’s encryption could fall dramatically, accelerating the urgency for companies and the Internet ecosystem to migrate to post-quantum security. Google has set a 2029 migration target, and Cloudflare is working toward a similar timeline.
