  • Post-Quantum, Deepfakes & Agile SASE: Cloudflare One's Biggest Week

    In this episode of This Week in NET, host João Tomé is joined by Warnessa Weaver (Senior Product Manager) and Yumna Moazzam (Senior Product Marketing Manager) to break down Cloudflare’s SASE blog takeover week and what it means for enterprise security.


    Cloudflare One is evolving into an agile, composable, and programmable SASE platform, built natively on Cloudflare’s global network spanning 300+ cities. The conversation explores how organizations can modernize remote access, secure AI adoption, and replace legacy architectures that often take 18 months to deploy with migrations completed in 4–6 weeks.


    The episode covers:

    • Post-quantum encryption now in GA for Cloudflare One

    • Deepfake defense through a new Nametag partnership

    • Adaptive access with user risk scoring and signals from CrowdStrike and SentinelOne

    • Programmable gateway policies using Cloudflare Workers

    • DLP visibility for Microsoft 365 Copilot, ChatGPT, Gemini and more

    • Clipboard controls for browser-based RDP sessions

    • Closing the boot-to-login security gap with the Cloudflare One client

    • CASB remediation for Microsoft 365 and Google Workspace


    The episode also includes a run-through of other recent Cloudflare blog posts, including AI Security for Apps (now GA), slashing agent token costs by 98% with RFC 9457, Nvidia Nemotron 3 Super on Cloudflare, and a new stateful API vulnerability scanner.

  • AI Deepfakes & Laptop Farms: Inside the 2026 Cloudflare Threat Report

    In this episode of This Week in NET, host João Tomé is joined by Cloudflare threat intelligence experts Brian Carter and Chris Peacey to break down the 2026 Cloudflare Threat Report and what it reveals about today’s cyber threat landscape.


    We discuss how threat intelligence helps organizations prioritize risks, how attackers are increasingly leveraging automation and AI tools, and why botnets, supply-chain attacks, and credential-theft campaigns continue to evolve.


    The conversation explores how attackers gain initial access, how criminal ecosystems operate across infrastructure providers and services, and how AI is beginning to influence reconnaissance, social engineering, and large-scale campaigns.


    We also examine geopolitical dimensions of cyber operations, the growing sophistication of phishing and identity attacks, and the role of threat intelligence in helping defenders anticipate and mitigate attacks before they escalate.

  • We Rebuilt Next.js with AI in One Week (vinext Explained)

    In this episode of This Week in NET (the second this week focused on building with AI), host João Tomé is joined by Steve Faulkner, Engineering Director at Cloudflare, to discuss how he rebuilt a Next.js-compatible framework in just one week using AI. The project, called vinext, began as an experiment and evolved into a working proof of concept.


    We explore what AI-first development looks like in practice, how coding agents were used to rewrite and test large API surfaces, and what happens when you treat dependencies as something you can regenerate rather than maintain manually.


    The results were surprising: faster local builds, smaller bundles, deployment to Workers with a single command, and a total AI token cost of roughly $1,100.


    We also discuss:

    • Using voice-to-code workflows (SuperWhisper + local models)

    • AI reviewing code multiple times

    • Whether AI-assisted rebuilds will become common

    • What this means for 2026 and beyond

  • Code Mode: Giving AI Agents an Entire API in 1,000 Tokens (With Demos)

    In this episode of This Week in NET, host João Tomé is joined by Matt Curry to break down Code Mode: a way to give AI agents access to the entire Cloudflare API (2,500+ endpoints) using two tools and roughly ~1,000 tokens of context.  


    Instead of exposing thousands of individual tools (which quickly becomes expensive and brittle), Code Mode lets the model write JavaScript to search and execute against a compact API context. The result is massive compression, lower cost, and better performance.


    We also include demos showing how agents can query real infrastructure, navigate multiple accounts, and build things like multiplayer experiences using Durable Objects and WebSockets.

  • Moltworker (for OpenClaw) & Markdown for Agents: Running AI on Cloudflare

    In this episode, host João Tomé is joined by Celso Martinho, VP of Engineering at Cloudflare, to discuss two major launches: Markdown for Agents and Moltworker (for OpenClaw) — and what they signal about the future of AI agents on the Internet.


    Celso explains how Markdown for Agents was conceived, built, and shipped in just one week, why AI systems prefer markdown over HTML, and how converting a typical blog post from 16,000 HTML tokens to roughly 3,000 markdown tokens can reduce cost, improve speed, and increase accuracy for AI models. We also explore Moltworker, a proof-of-concept showing how a personal AI agent originally designed to run on a Mac Mini can instead run on Cloudflare’s global network using Workers, R2, Browser Rendering, AI Gateway, and Zero Trust.


    We discuss observability for AI crawlers, new monetization models for publishers, the rapid growth of agent ecosystems, and why AI is becoming less hype and more infrastructure.

    • Introducing Moltworker: a self-hosted personal AI agent, minus the minis

  • Privacy in the AI Age: What's Really Changing in 2026 (with Cloudflare's CPO)

    In this episode of This Week in NET, host João Tomé is joined by Emily Hancock, Cloudflare’s Chief Privacy Officer and Data Protection Officer, for a wide-ranging conversation about privacy in 2026 and how the role has evolved in the age of AI.


    Emily explains how privacy officers shifted from GDPR compliance to broader data governance, responsible AI practices, cybersecurity collaboration, and cross-border data frameworks. We explore privacy by design, data minimization, vendor risk, government requests, warrant canaries, digital sovereignty, insider threats, and how AI is reshaping both attacker and defender capabilities.


    We also discuss Cloudflare’s approach to responsible AI, how teams use internal controls to avoid misuse of customer data, and why “human in the loop” remains essential for accuracy, safety, and trust.

  • Internet Disruptions & Iran’s Shutdown: Cloudflare Radar Insights (Storm in Portugal Included)

    In this episode, David Belson — Cloudflare’s Head of Data Insights — joins us to walk through the biggest Internet disruptions of late 2025 and early 2026.


    At the start, we also highlight several new posts on the Cloudflare Blog: Moltworker, a self-hosted personal AI agent built with OpenClaw (former MoltBot and ClawdBot) and Cloudflare’s Developer Platform; Post-Quantum Matrix Homeserver, a proof-of-concept encrypted messaging server running entirely on Cloudflare Workers; Route Leak Incident (Jan 22), what happened in Miami and how routing policy safeguards are being improved; Google’s AI Advantage, why crawler separation is needed for fair competition and better protection for publishers.


    We then go into the major Internet trends, including the storm-related disruption in three regions in Portugal this week. Our main focus is the government-directed nationwide shutdown in Iran. 


    Then we also go over Q4 2025 disruptions: repeated weather-driven outages across Africa and the Caribbean, submarine cable failures, DNS anomalies, and the persistent risk of centralized points of failure. David also explains how Starlink’s global footprint is reshaping Radar visibility — and why the Internet remains remarkably resilient despite a turbulent quarter.

  • Record-Breaking DDoS Attacks & the Security Landscape Heading Into 2026

    In this end-of-year episode of This Week in NET, host João Tomé is joined by Omer Yoachimik, Senior Product Manager for DDoS Protection at Cloudflare, to break down the realities of the 2025 DDoS threat landscape — and what’s coming next.


    They discuss how DDoS attacks reached previously “theoretical” scales in 2025, including record-breaking 31 Tbps attacks, the rise of massive botnets like Aisuru, and how geopolitical events increasingly shape cyber activity. Omer explains why traditional scrubbing-center defenses are becoming obsolete, how Cloudflare’s autonomous, globally distributed mitigation works, and why automation and real-time intelligence are now essential.


    The conversation closes with practical advice for organizations, common myths about DDoS risk, and what to expect in 2026 as attacks grow larger, faster, and more sophisticated.
