HTTP/3 inspection on Cloudflare Gateway

Today, we’re excited to announce upcoming support for HTTP/3 inspection through Cloudflare Gateway, our comprehensive secure web gateway. HTTP/3 currently powers 25% of the Internet and delivers a faster browsing experience, without compromising security. Until now, administrators seeking to filter and inspect HTTP/3-enabled websites or APIs needed to either compromise on performance by falling back to HTTP/2 or lose visibility by bypassing inspection. With HTTP/3 support in Cloudflare Gateway, you can have full visibility on all traffic and provide the fastest browsing experience for your users.

Why is the web moving to HTTP/3?

HTTP is one of the oldest technologies that powers the Internet. All the way back in 1996, security and performance were afterthoughts and encryption was left to the transport layer to manage. This model doesn’t scale to the performance needs of the modern Internet and has led to HTTP being upgraded to HTTP/2 and now HTTP/3.

HTTP/3 accelerates browsing activity by using QUIC, a modern transport protocol that is always encrypted by default. This delivers faster performance by reducing round-trips between the user and the web server and is more performant for users with unreliable connections. For further information about HTTP/3’s performance advantages take a look at Continue reading

Connect to private network services with Browser Isolation

If you’re working in an IT organization that has relied on virtual desktops but looking to get rid of them, we have some good news: starting today, you can connect your users to your private network via isolated remote browsers. This means you can deliver sensitive internal web applications — reducing costs without sacrificing security.

Browser Isolation with private network connectivity enables your users to securely access private web services without installing any software or agents on an endpoint device or absorbing the management and cost overhead of serving virtual desktops. What’s even better: Browser Isolation is natively integrated into Cloudflare’s Zero Trust platform, making it easy to control and monitor who can access what private services from a remote browser without sacrificing performance or security.

Deprecating virtual desktops for web apps

The presence of virtual desktops in the workplace tells an interesting story about the evolution of deploying and securing enterprise applications. Serving a full virtual desktop to end-users is an expensive decision, each user requiring a dedicated virtual machine with multiple CPU cores and gigabytes of memory to run a full operating system. This cost was offset by the benefits of streamlining desktop app distribution and the security Continue reading

Announcing Gateway + CASB

This post is also available in 简体中文, 日本語, Español.

Shadow IT and managing access to sanctioned or unsanctioned SaaS applications remain one of the biggest pain points for IT administrators in the era of the cloud.

We're excited to announce that starting today, Cloudflare’s Secure Web Gateway and our new API-driven Cloud Access Security Broker (CASB) work seamlessly together to help IT and security teams go from finding Shadow IT to fixing it in minutes.

Detect security issues within SaaS applications

Cloudflare's API-driven CASB starts by providing comprehensive visibility into SaaS applications, so you can easily prevent data leaks and compliance violations. Setup takes just a few clicks to integrate with your organization's SaaS services, like Google Workspace and Microsoft 365. From there, IT and security teams can see what applications and services their users are logging into and how company data is being shared.

So you’ve found the issues. But what happens next?

Identify and detect, but then what?

Customer feedback from the API-driven CASB beta has followed a similar theme: it was super easy to set up and detect all my security issues, but how do I fix this stuff?

Almost immediately after investigating the most Continue reading

Tailscale SSH Launches in Beta to Replace SSH Keys

Tailscale SSH, which simplifies authentication and authorization by replacing SSH keys with the Tailscale identity of any machine. A Secure Shell or SSH key is an access credential in the SSH.COM. Tailscale gives each server and user device its own identity and node key for authenticating and encrypting the Tailscale network connection and uses access control lists defined in code for authorizing connections, making it a natural extension for Tailscale to now manage access for SSH connections in your network. Removes the Pain “SSH is an everyday tool for developers, but managing SSH keys for a server isn’t so simple or secure,” said Tailscale Product Manager

Zero-trust for cloud-native workloads – part 2: Mitigating future Log4j incidents

Zero-trust for cloud-native workloads – part 2: Mitigating future Log4j incidents

In my previous blog, I introduced the brief history of zero trust, the core pillars of a zero-trust model, and how to build a zero-trust model for cloud-native workloads. In this blog, you will learn how Calico can help mitigate vulnerabilities such as the recent zero-day Log4j vulnerability with its zero-trust workload security approach.

Zero trust: a quick refresher

The starting point for building a zero-trust model is understanding your attack and protect surface. The outcome of designing your security plan should be eliminating the attack surface completely.

Enterprises are realizing that the best approach to mitigating breaches and protecting their sensitive assets from both internal and external threats is by applying the three principles of zero trust to their security plan. These three principles are:

1. Always use least-privilege access
2. Always authenticate and authorize before providing access
3. Always assume breach

While stakeholders are busy creating design architectures, collecting asset information, and considering tools required to achieve their zero trust goals, there are also new challenges that some decision-makers should consider. As microservices are becoming the de facto standard for application developers, it has introduced new technologies and methodologies Continue reading

The Path Is Set For PCI-Express 7.0 In 2025

The ink is barely dry on the PCI-Express 6.0 specification, which was released after years of development in January 2022, we hardly have PCI-Express 5.0 peripherals in the market, and the PCI-SIG organization that controls the PCI-Express standard for peripheral interconnects already has us all coveting the bandwidth that will come later in the decade with PCI-Express 7.0 interconnects. …

Early Hints update: How Cloudflare, Google, and Shopify are working together to build a faster Internet for everyone

A few months ago, we wrote a post focused on a product we were building that could vastly improve page load performance. That product, known as Early Hints, has seen wide adoption since that original post. In early benchmarking experiments with Early Hints, we saw performance improvements that were as high as 30%.

Now, with over 100,000 customers using Early Hints on Cloudflare, we are excited to talk about how much Early Hints have improved page loads for our customers in production, how customers can get the most out of Early Hints, and provide an update on the next iteration of Early Hints we’re building.

What Are Early Hints again?

As a reminder, the browser you’re using right now to read this page needed instructions for what to render and what resources (like images, fonts, and scripts) need to be fetched from somewhere else in order to complete the loading of this (or any given) web page. When you decide you want to see a page, your browser sends a request to a server and the instructions for what to load come from the server’s response. These responses are generally composed of a multitude of resources that tell the browser Continue reading

A stronger bridge to Zero Trust

We know that migration to Zero Trust architecture won’t be an overnight process for most organizations, especially those with years of traditional hardware deployments and networks stitched together through M&A. But part of why we’re so excited about Cloudflare One is that it provides a bridge to Zero Trust for companies migrating from legacy network architectures.

Today, we’re doubling down on this — announcing more enhancements to the Cloudflare One platform that make a transition from legacy architecture to the Zero Trust network of the future easier than ever: new plumbing for more Cloudflare One on-ramps, expanded support for additional IPsec parameters, and easier on-ramps from your existing SD-WAN appliances.

Any on- or off-ramp: fully composable and interoperable

When we announced our vision for Cloudflare One, we emphasized the importance of allowing customers to connect to our network however they want — with hardware devices they’ve already deployed, with any carrier they already have in place, with existing technology standards like IPsec tunnels or more Zero Trust approaches like our lightweight application connector. In hundreds of customer conversations since that launch, we’ve heard you reiterate the importance of this flexibility. You need a platform that meets you where you Continue reading

Using Cloudflare Tunnel and Access with Postgres

For a long time we used the traditional method of accessing internal database clusters by SSHing to a bastion host. Due to the overhead and limitations of maintaining the SSH configuration, we’ve moved to using Cloudflare Tunnels combined with Cloudflare Access to dramatically improve the user experience and onboarding times related to database access.

How we used to work

Internally we rely heavily on PostgreSQL to power many services at Cloudflare – including Stream, Images and the Cloudflare Dashboard itself. We run our Postgres clusters on our own hardware within our data centers, and they are not accessible to the public Internet, including employee laptops.

When an employee requires access to one of these databases – be it for staging environments, incident management, or supporting production services – an SSH user account is required. This SSH account has limited access on a bastion host, purely for querying databases within the data center.

The pain we experienced

Provisioning an SSH account to these bastion hosts requires submitting a pull request to our main Infrastructure-as-Code git repository. For engineers this is a cumbersome process, and for non-engineers it is either an unnecessary learning experience, or a burden to whomever they have to Continue reading

Cloudflare integrates with Microsoft Intune to give CISOs secure control across devices, applications, and corporate networks

Today, we are very excited to announce our new integration with Microsoft Endpoint Manager (Intune). This integration combines the power of Cloudflare’s expansive network and Zero Trust suite, with Endpoint Manager. Via our existing Intune integration, joint customers can check if a device management profile such as Intune is running on the device or not and grant access accordingly.

With this expanded integration, joint customers can identify, investigate, and remediate threats faster. The integration also includes the latest information from Microsoft Graph API which provides many added, real-time device posture assessments and enables organizations to verify users' device posture before granting access to internal or external applications.

"In today’s work-from-anywhere business culture, the risk of compromise has substantially increased as employees and their devices are continuously surrounded by a hostile threat environment outside the traditional castle-and-moat model. By expanding our integration with Cloudflare, we are making it easier for joint customers to strengthen their Zero Trust security posture across all endpoints and their entire corporate network."
– Dave Randall, Sr Program Manager, Microsoft Endpoint Manager

Before we get deep into how the integration works, let’s first recap Cloudflare’s Zero Trust Services.

Cloudflare Gateway dedicated egress and egress policies

Today, we are highlighting how Cloudflare enables administrators to create security policies while using dedicated source IPs. With on-premise appliances like legacy VPNs, firewalls, and secure web gateways (SWGs), it has been convenient for organizations to rely on allowlist policies based on static source IPs. But these hardware appliances are hard to manage/scale, come with inherent vulnerabilities, and struggle to support globally distributed traffic from remote workers.

Throughout this week, we’ve written about how to transition away from these legacy tools towards Internet-native Zero Trust security offered by services like Cloudflare Gateway, our SWG. As a critical service natively integrated with the rest of our broader Zero Trust platform, Cloudflare Gateway also enables traffic filtering and routing for recursive DNS, Zero Trust network access, remote browser isolation, and inline CASB, among other functions.

Nevertheless, we recognize that administrators want to maintain the convenience of source IPs as organizations transition to cloud-based proxy services. In this blog, we describe our approach to offering dedicated IPs for egressing traffic and share some upcoming functionality to empower administrators with even greater control.

Cloudflare’s dedicated egress IPs

Source IPs are still a popular method of verifying that traffic originates from a known organization/user when Continue reading

MPLS to Zero Trust in 30 days

Employees returning to the office are experiencing that their corporate networks are much slower compared to what they’ve been using at home. It’s partly due to outdated line speeds, and also partly due to security requirements that force all traffic to get backhauled through centralized data centers. While 44% of the US currently has access to fiber-based broadband Internet with speeds reaching 1 Gbps, many MPLS sites are still on old 1.5 Mbps circuits. This is a reality check and a reminder that the current MPLS based networks are unable to support the shift from centralized applications in the datacenter to a distributed SaaS and hybrid multi-cloud world.

In this post, we are going to outline the steps required to take your network from MPLS to Zero Trust. But, before we do — a little about how we ended up in this situation.

Enterprise networks today

Over the past 10 years, most enterprise networks have evolved from perimeter hub and spoke networks into franken-networks as a means to solve connectivity and security issues. We have not had a chance to redesign them holistically for distributed application access. The band-aid and point solutions have only pushed the problems further down Continue reading
