Today, we are extending Cloudflare’s cloud access security broker (CASB) to support the Claude Compliance API. Security and compliance teams can now monitor Claude usage directly in the Cloudflare dashboard. No endpoint agents required. Enterprise security teams have long struggled to see how users interact with sanctioned and unsanctioned applications. The rapid adoption of AI applications has made this harder.

On April 29, 2026, a Linux kernel local privilege escalation vulnerability was publicly disclosed under the name "Copy Fail" (CVE-2026-31431). Cloudflare’s Security and Engineering teams began assessing the vulnerability as soon as it was disclosed. We reviewed the exploit technique, evaluated exposure across our infrastructure, and validated that our existing behavioral detections could identify the exploit pattern within minutes.

On May 5, 2026, at roughly 19:30 UTC, DENIC, the registry operator for the.de country-code top-level domain (TLD), started publishing incorrect DNSSEC signatures for the.de zone. Any validating DNS resolver receiving these signatures was required by the DNSSEC specification to reject them and return SERVFAIL to clients, including 1.1.1.1, the public DNS resolver operated by Cloudflare. The country-code top-level domain for Germany, .de, is one of the largest on the Internet.

While more than two-thirds of human-generated TLS traffic to Cloudflare is already protected by post-quantum cryptography, the world of site-to-site networking has been a different story. For years, the IPsec community remained caught between the high bar of Internet-scale interoperability and the niche requirements of specialized hardware. That gap is now closing.

In the first quarter of 2026, government-directed shutdowns figured prominently, with prolonged Internet blackouts in both Uganda and Iran, a stark contrast to the lack of observed government-directed shutdowns in the same quarter a year prior. This quarter, we also observed a number of Internet disruptions caused by power outages, including three separate collapses of Cuba's national electrical grid.

For us humans to interact with the online world, we need a gateway: keyboard, screen, browser, device. What is called "human detection" online are patterns that humans use when interacting with such devices.

We have thousands of internal apps at Cloudflare. Some are things we’ve built ourselves, others are self-hosted instances of software built by others. They range from business-critical apps nearly every person uses, to side projects and prototypes. All of these apps are protected by Cloudflare Access. But when we started using and building agents — particularly for uses beyond writing code — we hit a wall. People could access apps behind Access, but their agents couldn’t.

Agents let you build software faster than ever, but securing your environment and the code you write — from both mistakes and malice — takes real effort. Open Web Application Security Project (OWASP) details a number of risks present in agentic AI systems, including the risk of credential leaks, user impersonation, and elevation of privilege.

AI agents have changed how teams think about private network access. Your coding agent needs to query a staging database. Your production agent needs to call an internal API. Your personal AI assistant needs to reach a service running on your home network. The clients are no longer just humans or services. They're agents, running autonomously, making requests you didn't explicitly approve, against infrastructure you need to keep secure.

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.

For decades, enterprise IT relied on a “hub and spoke” security model. But between the explosion of cloud infrastructure, SaaS apps and a remote workforce, that old perimeter hasn't just cracked—it’s shattered. In an attempt to stay on top of the advancing perimeter, many different solutions from many vendors entered the market and created a "spaghetti mess" of point solutions that drive up costs and tank user experience. Cloudflare is an answer to this problem, delivering everything you need to secure your apps, networks, users, data and devices.
