How we built Organizations to help enterprises manage Cloudflare at scale

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. 

Enterprise customers often use multiple Cloudflare Accounts to segment their teams (allowing more autonomy and separation of roles), but this can cause a new set of problems for the administrators by fragmenting their controls.

That’s why today, we’re launching our new Organizations feature in beta — to provide a cohesive place for administrators to manage users, configurations, and view analytics across many Cloudflare Accounts. 

Principle of least privilege

The principle of least privilege is one of the driving factors behind enterprises using multiple accounts. While Cloudflare’s role-based access control (RBAC) system now offers fine-grained permissions for many resources, it can be cumbersome to enumerate all the resources one by one. Instead, we see enterprises use multiple accounts, so each team’s resources are managed by that team alone. This allows organic Continue reading

Stanford researchers are warning that using AI chatbots for personal advice could backfire. The problem isn’t just accuracy, it’s how these systems respond when you’re dealing with complicated, real-world conflicts.

 


During the APNIC Routing Security Special Interest Group (SIG) session at APRICOT 2026 / APNIC 61, APNIC and LACNIC presented a case study of a Border Gateway Protocol (BGP) hijack that combined a technical attack with social engineering.

 


It is widely believed that all BGP routers within an Autonomous System (AS) must be connected in a full iBGP mesh, or, when this becomes impractical, that route reflectors or confederations must be used. However, a full mesh is not always necessary, and in some scenarios it may even be undesirable.

 


The skies are quickly filling with communications satellites. Following is a short list of the many ventures that have or will soon be launching large numbers of broadband satellites.

 


In early demos, the system looked impressive. It could summarize logs, explain configuration issues, and suggest possible fixes. Instead of digging through internal docs, the answers were coming back in seconds. For a while, it really felt like this system was going to work as expected.

What appears as double extraction at the operator level becomes something larger and more serious at the level of the state. It becomes sovereignty inversion.

 


Major memory makers have already sold all the kit they can make this year, creating shortages and price increases.

 


It’s fading from our collective memory, but almost thirty years ago the global IT industry was gripped by Y2K fever.

 


What do you get when you combine Big Tech, a Bill Clinton fixer, Davos, the architect of the Hunter Biden laptop disinfo, and “Artificial Intelligence”? The biggest heist in world history.

 


Stop blaming the GPUs! Your AI feels slow because data is getting stuck in traffic. Fix the “supply chain” to keep those tokens flowing.

Technology Short Take 193

Welcome to Technology Short Take #193! I know it has only been a couple weeks since the last Tech Short Take, but I am guessing that readers won’t really mind another one. Here is my latest collection of articles and posts about data center-related technologies. Enjoy!

Networking

Servers/Hardware

  • RIP Mac Pro. I had a “classic Mac Pro” (2012 era) for a long time, and I loved that system. (I even ran Linux on it for a while.) It is a shame to see it go.
  • I mentioned on social media (Mastodon/Bluesky) that I recently purchased all the hardware for a new PC build. It’ll be part PC/part home server, as I look to expand the type and scope of services that I self-host. Don’t be surprised if a few articles emerge out of this.

How to Stub LLMs for AI Agent Security Testing and Governance

Note: The core architecture for this pattern was introduced by Isaac Hawley from Tigera.

If you are building an AI agent that relies on tool calling, complex routing, or the Model Context Protocol (MCP), you’re not just building a chatbot anymore. You are building an autonomous system with access to your internal APIs.

With that power comes a massive security and governance headache, and AI agent security testing is where most teams hit a wall. How do you definitively prove that your agent’s identity and access management (IAM) actually works?

The scale of the problem is hard to overstate. Microsoft’s telemetry shows that 80% of Fortune 500 companies now run active AI agents, yet only 47% have implemented specific AI security controls. Most teams are deploying agents faster than they can test them.

If an agent is hijacked via prompt injection, or simply hallucinates a destructive action, does your governance layer stop it? Testing this usually forces engineers into a frustrating trade-off:

  1. Use the real API (Gemini, OpenAI): Real models are heavily RLHF’d to be safe and polite. It is incredibly difficult (and non-deterministic) to intentionally force a real model to “go rogue” and consistently output malicious tool Continue reading

Why we’re rethinking cache for the AI era

Cloudflare data shows that 32% of traffic across our network originates from automated traffic. This includes search engine crawlers, uptime checkers, ad networks — and more recently, AI assistants looking to the web to add relevant data to their knowledge bases as they generate responses with retrieval-augmented generation (RAG). Unlike typical human behavior, AI agents, crawlers, and scrapers’ automated behavior may appear aggressive to the server responding to the requests. 

For instance, AI bots frequently issue high-volume requests, often in parallel. Rather than focusing on popular pages, they may access rarely visited or loosely related content across a site, often in sequential, complete scans of the websites. For example, an AI assistant generating a response may fetch images, documentation, and knowledge articles across dozens of unrelated sources.

Although Cloudflare already makes it easy to control and limit automated access to your content, many sites may want to serve AI traffic. For instance, an application developer may want to guarantee that their developer documentation is up-to-date in foundational AI models, an e-commerce site may want to ensure that product descriptions are part of LLM search results, or publishers may want to get paid for their content through mechanisms such Continue reading

SR Linux Configuration Conversion Tool

A year ago, I was complaining about SR Linux breaking its configuration data model with a new software release. At that time, I was promised it would only happen once a year, and, like clockwork, that moment arrived with the SR Linux release 26.03.

However, this year Miguel Redondo fixed the netlab SR Linux configuration templates (VRF export policies, LocPref routing policy changes) before I could even start looking at them, and Roman Dodin released a tool that tells you exactly what changed between software releases and how to fix it.

Our ongoing commitment to privacy for the 1.1.1.1 public DNS resolver

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. In 2020, we hired an independent firm to check our work, instead of just asking you to take our word for it. We shared our intention to update such examinations in the future. We also called on other providers to do the same, but, as far as we are aware, no other major public resolver has had their DNS privacy practices independently examined.

At the time of the 2020 review, the 1.1.1.1 resolver was less than two years old, and the purpose of the examination was to prove our systems made good on all the commitments we made about how our 1.1.1.1 resolver functioned, even commitments that did not impact personal data or user privacy. 

Since then, Cloudflare’s technology Continue reading

Introducing EmDash — the spiritual successor to WordPress that solves plugin security

The cost of building software has drastically decreased. We recently rebuilt Next.js in one week using AI coding agents. But for the past two months our agents have been working on an even more ambitious project: rebuilding the WordPress open source project from the ground up.

WordPress powers over 40% of the Internet. It is a massive success that has enabled anyone to be a publisher, and created a global community of WordPress developers. But the WordPress open source project will be 24 years old this year. Hosting a website has changed dramatically during that time. When WordPress was born, AWS EC2 didn’t exist. In the intervening years, that task has gone from renting virtual private servers, to uploading a JavaScript bundle to a globally distributed network at virtually no cost. It’s time to upgrade the most popular CMS on the Internet to take advantage of this change.

Our name for this new CMS is EmDash. We think of it as the spiritual successor to WordPress. It’s written entirely in TypeScript. It is serverless, but you can run it on your own hardware or any platform you choose. Plugins are securely sandboxed and can run in their own isolate, Continue reading

Every Layer of Review Makes You 10x Slower

Avery Pennarun published yet another excellent article: every layer of review makes you 10x slower, effectively reiterating what I’ve been saying for decades: all the technology in the world won’t help you unless you re-architect the broken processes.

AI is no exception, but of course, the AI evangelists, LinkedIn AI Wranglers1, and Thought Leaders will never tell you that (or even admit it).

  1. Yes, you can find BS like that on LinkedIn. You’re not surprised, are you? ↩︎
