Evolving Cloudflare’s Threat Intelligence Platform: actionable, scalable, and ETL-less

For years, the cybersecurity industry has suffered from a "data gravity" problem. Security teams are buried under billions of rows of telemetry, yet they remain starved for actionable insights. 

A Threat Intelligence Platform (TIP) is a centralized security system that collects, aggregates, and organizes data about known and emerging cyber threats. It serves as the vital connective tissue between raw telemetry and active defense.

The underlying architecture of Cloudflare’s Threat Intelligence Platform sets it apart from other solutions. We have evolved our Threat Intelligence Platform to eliminate the need for complex ETL (Extract, Transform, Load) pipelines by using a sharded, SQLite-backed architecture. By running GraphQL directly on the edge, security teams can now visualize and automate threat response in real time. Instead of one massive database, we distribute Threat Events across thousands of logical shards — meaning sub-second query latency, even when aggregating millions of events across global datasets.

By unifying our global telemetry with the manual investigations performed by our analysts, our intelligence platform creates a single source of truth that allows security teams to move from observing a threat to preemptively blocking it across the Cloudflare network. We believe your intelligence platform shouldn't just tell you that Continue reading

Introducing the 2026 Cloudflare Threat Report

Today’s threat landscape is more varied and chilling than ever: Sophisticated nation-state actors. Hyper-volumetric DDoS attacks. Deepfakes and fraudsters interviewing at your company. Even stealth attacks via trusted internal tools like Google Calendar, Dropbox, and GitHub.

After spending the last year translating trillions of network signals into actionable intelligence, Cloudforce One has identified a fundamental evolution in the threat landscape: the era of brute force entry is fading. In its place is a model of high-trust exploitation that prioritizes results at all costs. In order to equip defenders with a strategic roadmap for this new era, today we are releasing the inaugural 2026 Cloudflare Threat Report. This report provides the intelligence organizations need to navigate the rise of industrialized cyber threats.

The new barometer for risk: Measure of Effectiveness (MOE)

Cloudforce One has observed a broader shift in attacker psychology. To understand how these methods win, we have to look at the why behind them: the Measure of Effectiveness, or MOE.

In 2026, the modern adversary is trading the pursuit of "sophistication" (complex, expensive, one-off hacks) in favor of throughput. MOE is the metric attackers use to decide what to exploit next. It is a cold calculation of the Continue reading

How Cloudy translates complex security into human action

Today’s security ecosystem generates a staggering amount of complex telemetry. For instance, processing a single email requires analyzing sender reputation, authentication results, link behavior, infrastructure metadata, and countless other attributes. Simultaneously, Cloud access security broker (CASB) engines continuously scan SaaS environments for signals that detect misconfigurations, risky access, and exposed data.

But while detections have become more sophisticated, explanations have not always kept pace.

Security and IT teams are often aware when something is flagged, but they do not always know, at a glance, why. End users are asked to make real-time decisions about emails that may impact the entire organization, yet they are rarely given clear, contextual guidance in the moment that matters.

Cloudy changes that.

Cloudy is our LLM-powered explanation layer, built directly into Cloudflare One. It translates complex machine learning outputs into precise, human-readable guidance for security teams and end users alike. Instead of exposing raw technical signals, Cloudy surfaces the reasoning behind a detection in a way that drives informed action.

For Cloudflare Email Security, this means helping users understand why a message was flagged before they escalate it to the security operations center, or SOC. For Cloudflare CASB, it means helping administrators quickly understand Continue reading

From reactive to proactive: closing the phishing gap with LLMs

Email security has always been defined by impermanence. It is a perpetual call-and-response arms race, where defenses are only as strong as the last bypass discovered and attackers iterate relentlessly for even marginal gains. Every control we deploy eventually becomes yesterday’s solution.

What makes this challenge especially difficult is that our biggest weaknesses are, by definition, invisible.

This problem is best illustrated by a classic example from World War II. Mathematician Abraham Wald was tasked with helping Allied engineers decide where to reinforce bomber aircraft. Engineers initially focused on the bullet holes visible on planes returning from missions. Wald pointed out the flaw: they were reinforcing the areas where planes could already take damage and survive. The true vulnerabilities were on the planes that never came back.

Email security faces an identical hurdle: our detection gaps are unseen. By integrating LLMs, we advance email phishing protection and move from reactive to proactive detection improvement.

The limits of reactive defense

Traditional email security systems improve primarily through user-reported misses. For example, if we marked a spam message as clean, customers can send us the original EML to our pipelines for our analysts to analyze and update our models. This feedback loop Continue reading

See risk, fix risk: introducing Remediation in Cloudflare CASB

Starting today, Cloudflare CASB customers can do more than see risky file-sharing across their SaaS apps: they can fix it, directly from the Cloudflare One dashboard.

This launch marks a huge advancement for Cloudflare’s Cloud Access Security Broker (CASB). Since its release, Cloudflare’s API-based CASB has focused on providing robust, comprehensive visibility and detection. It also connects to the SaaS tools your business runs on, surfacing misconfigurations, and flagging overshared data before it becomes tomorrow’s incident.

With today’s release of Remediation – a new way to fix problems with just a click, right from the CASB Findings page – CASB begins its next chapter, and moves from telling you what’s wrong to helping you make it right.

An example of a Remediation Action (Remove Public File Sharing) in a CASB Finding.

CASB 101: A single place to see SaaS risk

Inside Cloudflare One, our SASE platform, CASB connects to the SaaS and cloud tools your teams already use. By talking to providers over API, CASB gives security and IT teams:

  • A consolidated view of misconfigurations, overshared files, and risky access patterns across apps like Microsoft 365, Google Workspace, Slack, Salesforce, Box, GitHub, Jira, and Confluence (CASB Integrations).

Running the Azure CLI in a Container

Like perhaps some readers, I am quite particular about what gets installed on my systems. I try to keep my systems as “clean” as possible, doing my best to avoid tools that have an extensive list of dependencies that must be installed and updated. Where that isn’t possible—such as with the Azure CLI, which has a massive number of Python modules that are required in order for the tool to function—I will use various isolation mechanisms. For the Azure CLI, that’s typically been a Python virtual environment. Somewhat recently, though, I had an idea to try using a container. In this post, I’ll share what worked and what did not work when trying to run the Azure CLI in a container.

First, though, a disclaimer: I am not an Azure expert, nor am I a Python expert. I know enough to get by. If I share something here that’s incorrect, please contact me and constructively show me my errors so that I can fix them.

Before I started down this path, I was sure this would be a slam dunk. I mean, this is what containers are for, right? If you do some web searches for running the Azure CLI Continue reading

Packet trimming Deep Dive – Part IV

Receive Network Processing Unit (Rx NPU)

Figure 9-4 illustrates a simplified receive-side processing pipeline, starting from the moment a Packet Header Vector (PHV), constructed by the Rx IFG, is delivered to the Receive Network Processing Unit (Rx NPU).

When the PHV arrives at the Rx NPU, it is dispatched to one of the Run-to-Completion (RTC) cores in the Packet Processing Array (PPA). Each RTC core processes the packet within a single execution context, allowing parsing, classification, lookup, and queuing decisions to be resolved without intermediate handoffs between processing stages.

The first task of the RTC parser is to perform deep inspection of the packet headers. While the Rx IFG has already extracted basic Layer-2 and Layer-3 information, the RTC parser determines whether the packet is tunneled and whether the switch itself is the tunnel termination point. To demonstrate this behavior, consider a VXLAN-encapsulated packet. The outer Ethernet and IP headers are used to forward the packet through the underlay network. If the outer destination IP address matches one of the local switch IP addresses, the device identifies itself as the tunnel endpoint. The tunneling protocol is recognized by examining the UDP header, where destination port 4789 indicates VXLAN. After the Continue reading

Modernizing with agile SASE: a Cloudflare One blog takeover

Return to office has stalled for many, and the “new normal” for what the corporate network means is constantly changing.  In 2026, your office may be a coffee shop, your workforce includes autonomous AI agents, and your perimeter is wherever the Internet reaches. This shift has forced a fundamental change in how we think about security, moving us toward a critical new architecture: agile SASE.

For too long, organizations have struggled under a 'fragmentation penalty,' juggling a patchwork of legacy hardware and Virtual Private Network (VPN) concentrators. These tools don't just require massive upfront investment; they create a mountain of technical debt — the cumulative cost of maintaining thousands of conflicting firewall rules, manual patches, and aging hardware that can’t support AI-scale traffic.

First-generation SASE providers promised a cure, but often just moved the mess to the cloud. By treating every data center as an isolated island, they’ve replaced hardware silos with operational silos. The result isn't a lack of visibility, but a lack of actionability: plenty of data, but no single way to enforce a consistent policy across a borderless enterprise.

Our customers have told us they need  an agile and composable platform. This week, we are announcing Continue reading

Beyond the blank slate: how Cloudflare accelerates your Zero Trust journey

In the world of cybersecurity, "starting from scratch" is a double-edged sword. On one hand, you have a clean slate; on the other, you face a mountain of configurations, best practices, and potential "gotchas."

While Cloudflare One has been often cited as one of the easiest-to-use SASE platforms, there is no magic without proper configuration. And while Cloudflare has been striving to simplify complex networking concepts by creating products such as Cloudflare WAN, Magic Transit, and Cloudflare Network Firewall, which simplify and reduce the typical complexity associated with deploying comparable functions from other vendors, the breadth of capabilities provided by Cloudflare One require creation of best-practice policies and templates to achieve the most optimal outcomes.

To make it easy to start taking advantage of Cloudflare’s powerful SASE platform, we have developed a method that ensures customers get the right configuration quickly and easily. We call it Project Helix. 

In this post, we’ll dig into the problem of getting the correct customization, and how we built Project Helix to make it simple. That means our customers have access to the most powerful SASE platform out there — and the easiest to onboard.

The complexity barrier: Why Continue reading

The truly programmable SASE platform

Every organization approaches security through a unique lens, shaped by their tooling, requirements, and history. No two environments look the same, and none stay static for long. We believe the platforms that protect them shouldn't be static either.

Cloudflare built our global network to be programmable by design, so we can help organizations unlock this flexibility and freedom. In this post, we’ll go deeper into what programmability means, and how Cloudflare One, our SASE platform, helps customers architect their security and networking with our building blocks to meet their unique and custom needs.

What programmability actually means

The term programmability has become diluted by the industry. Most security vendors claim programmability because they have public APIs, documented Terraform providers, webhooks, and alerting. That’s great, and Cloudflare offers all of those things too.

These foundational capabilities provide customization, infrastructure-as-code, and security operations automation, but they're table stakes. With traditional programmability, you can configure a webhook to send an alert to Slack when a policy triggers.

But the true value of programmability is something different. It is the ability to intercept a security event, enrich it with external context, and act on it in real time. Say a user attempts to Continue reading

Packet Trimming Deep Dive – Part III

Virtual Output Queue (VOQ)


The Silicon One VOQ Architecture

Instead of using dedicated deep interface buffers for packet queuing, Cisco Silicon One utilizes a Centralized Shared Memory architecture paired with a logical Virtual Output Queue (VOQ) mechanism. Because the VOQ concept is implemented within the Ingress (Rx) NPU entity, this queuing stage occurs after the initial ingress lookups but before the packet is switched across the internal fabric to the egress.

The VOQ model turns the traditional egress queuing model, where packets wait for serialization in a hardware buffer on the specific egress interface, upside down. While a VOQ is physically located on the ingress NPU, its ability to send traffic is controlled by the state of a small hardware Output Queue (OQ) on the egress interface.


Priority Mapping and Default State

As shown in Figure 9-3, a QoS policy can be created where a packet received on interface gi1/0/1 is assigned to Traffic Class 6 if the DSCP bits are set to EF (Expedited Forwarding). This configuration instantiates a VOQ specifically for that traffic class. In this hierarchy:

TC 7 (Control Plane/CS6): Mapped to OQ 1, the highest Strict Priority (Level 1).

TC 6 (DSCP-TRIMMED/EF): Mapped to OQ 2, Continue reading
