    Cloudflare’s Agents Week: Building Infrastructure for AI Agents

    In this special Agents Week edition of This Week in NET, host João Tomé is joined by Ming Lu (Principal Product Manager) and Anni Wang (Product Manager) to recap Cloudflare’s first-ever Agents Week. 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. At the end of the episode, there is also a fun recap video made by Zeke Sikelianos (Principal Systems Engineer, Developer Relations), using a deepfake version of himself to summarize the week’s announcements through Thursday.

    “It’s Quite a Shock”: The Quantum Deadline Is Real

    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. Bas, who has spent years deploying post-quantum cryptography at Cloudflare, explains why the shift from theoretical risk to practical planning is happening now, what “Q-Day” would actually mean, and why upgrading the Internet’s cryptography is one of the largest coordinated security transitions ever attempted. The episode also covers the difference between post-quantum encryption and authentication, how quantum computers work, and what organisations should start doing today to prepare.

    Cloudflare Agents Week Preview: What to Expect

    In this short edition of This Week in NET, host João Tomé joins from the island of Madeira for a quick preview of Cloudflare’s first Agents Week. João is joined by Ming Lu (Principal Product Manager at Replicate) and Anni Wang (Product Manager) to discuss why AI agents are becoming one of the biggest shifts happening on the Internet right now. They explore how agents are starting to generate more code than developers, why the Internet is moving toward agents interacting with other agents, and what infrastructure is needed to build and run them securely at scale. The conversation also previews some of the themes of Agents Week: building and running agents on Cloudflare’s platform, securing agent access to tools and data, managing the large volumes of data agents generate, and how the web itself may change as machines increasingly consume content.

    EmDash: The WordPress Successor That Fixes Plugin Security

    In this episode of This Week in NET, host João Tomé is joined by Matt “TK” Taylor (Senior Product Manager) and Matt Kane (Senior Principal Systems Engineer) to discuss EmDash, a new CMS launched by Cloudflare as a modern, serverless alternative inspired by WordPress. Built on Astro and designed for today’s developer workflows, EmDash combines the familiarity of traditional CMS platforms with a modern architecture: serverless deployment, TypeScript throughout, and a plugin system designed to solve one of WordPress’s biggest challenges — security. The conversation explores why plugin vulnerabilities account for the vast majority of WordPress security issues, and how EmDash addresses that by running plugins in sandboxed Worker isolates with tightly scoped permissions. Matt and Matt also discuss how AI agents were used during development, why the project is MIT licensed, and how the CMS is designed from the ground up to work with AI agents through MCP and structured content. Later in the episode we see the EmDash playground, how WordPress sites can be imported in minutes, and how developers can start building plugins and extensions today.

    Kimi Found 40+ Security Issues in Our Code. Open Source AI Is Here | Michelle Chen

    In this episode of This Week in NET, host João Tomé is joined by Michelle Chen from Cloudflare’s AI product team to discuss the rise of open models, the launch of Kimi 2.5 on Workers AI, and why enterprises are rethinking the cost of proprietary AI. Michelle explains how Cloudflare’s security team used Kimi to scan internal codebases and found more than 40 confirmed security issues — at a fraction of the cost of proprietary models. The conversation explores why open models are rapidly becoming competitive with closed alternatives, how Cloudflare builds efficiency with custom inference engines and prefix caching, and what the Replicate acquisition means for bring-your-own-model workflows on Workers AI.

    From SQL Injection to Cloudflare VP: Chema Alonso on 25 Years of Hacking

    In this episode of This Week in NET, host João Tomé is joined by Chema Alonso, Vice President and Head of International Development at Cloudflare. Chema shares how a 1998 paper on SQL injection launched his career in hacking, his path from running a startup in Madrid to becoming a Microsoft MVP for 14 years, and how he ended up leading cybersecurity at Telefónica for more than a decade — after telling them “you don’t have enough money to make me work for you.” He also explains why he left Telefónica in 2025 to join Cloudflare, and what surprised him about the company’s technical depth. The conversation explores how AI is changing cybersecurity, from AI agents competing in Capture-the-Flag contests to automated attack chains running around the clock. Chema also discusses the black market for zero-day vulnerabilities, Cloudflare’s role in Europe, and how AI may reshape the economics of the Internet. We also hear the story behind his famous beanie hat, a Bluetooth exploit that Apple initially called “a feature” until Steve Wozniak got involved and a quick-fire round covering his first computer, favorite hacks, admired researchers, and why Gemini once hallucinated that he went to jail. ⏱️ Timestamps  01:00 — How SQL injection in 1998 started his career 02:36 — From startup to Microsoft MVP to training Spain's cyber forces 04:36 — Black Hat, Def Con, and the global hacking scene 05:53 — How Telefonica recruited Chema 08:49 — 20 years of daily blogging as "brain gym" 10:27 — The beanie hat origin story 14:34 — Why he left Telefonica to join Cloudflare 17:41 — What customers are most worried about: AI security 22:55 — Cloudflare's role in Europe: sovereignty, resilience, and growth 26:58 — How AI is disrupting the Internet's business model 28:44 — The evolution of hacking: from phreaking to AI agents 37:42 — The Dirty Tooth iPhone Bluetooth exploit and Steve Wozniak 41:39 — Quick-fire round: first computer, favorite hack, Kevin Mitnick 43:58 — Google Gemini hallucinated that Chema went to jail 46:49 — The future of the Internet and Cloudflare
