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.

Cloudflare is accelerating its post-quantum roadmap. We now target 2029 to be fully post-quantum (PQ) secure including, crucially, post-quantum authentication.

Cloudflare was designed to be simple to use for even the smallest customers, but it’s also critical that it scales to meet the needs of the largest enterprises. While smaller customers might work solo or in a small team, enterprises often have thousands of users making use of Cloudflare’s developer, security, and networking capabilities. This scale can add complexity, as these users represent multiple teams and job functions.

Exactly 8 years ago today, we launched the 1.1.1.1 public DNS resolver, with the intention to build the world’s fastest resolver — and the most private one. We knew that trust is everything for a service that handles the "phonebook of the Internet." That’s why, at launch, we made a unique commitment to publicly confirm that we are doing what we said we would do with personal data.

We're proud to introduce Programmable Flow Protection: a system designed to let Magic Transit customers implement their own custom DDoS mitigation logic and deploy it across Cloudflare’s global network. This enables precise, stateful mitigation for custom and proprietary protocols built on UDP. It is engineered to provide the highest possible level of customization and flexibility to mitigate DDoS attacks of any scale.

Client-side skimming attacks have a boring superpower: they can steal data without breaking anything. The page still loads. Checkout still completes. All it needs is just one malicious script tag. If that sounds abstract, here are two recent examples of such skimming attacks: To further our goal of building a better Internet, Cloudflare established a core tenet during our Birthday Week 2025: powerful security features should be accessible without requiring a sales engagement.

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.
