Clientless Web Isolation is now generally available
Today, we’re excited to announce that Clientless Web Isolation is generally available. A new on-ramp for Browser Isolation that natively integrates Zero Trust Network Access (ZTNA) with the zero-day, phishing and data-loss protection benefits of remote browsing for users on any device browsing any website, internal app or SaaS application. All without needing to install any software or configure any certificates on the endpoint device.
Cloudflare’s clientless web isolation simplifies connections to remote browsers through a hyperlink (e.g.: https://<your-auth-domain>.cloudflareaccess.com/browser). We explored use cases in detail in our beta announcement post, but here’s a quick refresher on the use cases that clientless isolated browsing enables:
Share secure browsing across the entire team on any device
Simply navigating to Clientless Web Isolation will land your user such as an analyst, or researcher in a remote browser, ready to securely conduct their research or investigation without exposing their public IP or device to potentially malicious code on the target website.
Deep link into isolated browsing
Suspicious hyperlinks and PDF documents from sensitive applications can be opened in a remote browser by rewriting the link with the clientless endpoint. For example:
https://<authdomain>.cloudflareaccess.com/browser/https://www.example.com/suspiciouslink

Packet captures at the edge
Packet captures are a critical tool used by network and security engineers every day. As more network functions migrate from legacy on-prem hardware to cloud-native services, teams risk losing the visibility they used to get by capturing 100% of traffic funneled through a single device in a datacenter rack. We know having easy access to packet captures across all your network traffic is important for troubleshooting problems and deeply understanding traffic patterns, so today, we’re excited to announce the general availability of on-demand packet captures from Cloudflare’s global network.
What are packet captures and how are they used?
A packet capture is a file that contains all packets that were seen by a particular network box, usually a firewall or router, during a specific time frame. Packet captures are a powerful and commonly used tool for debugging network issues or getting better visibility into attack traffic to tighten security (e.g. by adding firewall rules to block a specific attack pattern).
A network engineer might use a pcap file in combination with other tools, like mtr, to troubleshoot problems with reachability to their network. For example, if an end user reports intermittent connectivity to a specific application, an engineer Continue reading
Cloudflare and Aruba partner to deliver a seamless global secure network from the branch to the cloud
Today we are excited to announce that Cloudflare and Aruba are working together to develop a solution that will enable Aruba customers to connect EdgeConnect SD-WAN’s with Cloudflare's global network to further secure their corporate traffic with Cloudflare One. Whether organizations need to secure Internet-bound traffic from branch offices using Cloudflare's Secure Web Gateway & Magic Firewall, or enforce firewall policies for east/west traffic between offices via Magic Firewall, we have them covered. This gives customers peace of mind that they have consistent global security from Cloudflare while retaining granular control of their inter-branch and Internet-bound traffic policies from their Aruba EdgeConnect appliances.
SD-WAN solution
A software-defined WAN (SD-WAN) is an evolution of a WAN (wide area network) that simplifies the underlying architecture. Unlike traditional WAN architecture models where expensive leased, and MPLS links are used, SD-WAN can efficiently use a combination of private lines and the public Internet. It brings together the best of both worlds to provide an integrated solution to network administrators in managing and scaling their network and resources with ease.
Aruba’s EdgeConnect SD-WAN solution
We are proud to announce our first enhanced SD-WAN integration. Aruba’s EdgeConnect solution is an industry leader for WAN edge Continue reading
Cloudflare and CrowdStrike partner to give CISOs secure control across devices, applications, and corporate networks
Today, we are very excited to announce multiple new integrations with CrowdStrike. These integrations combine the power of Cloudflare’s expansive network and Zero Trust suite, with CrowdStrike’s Endpoint Detection and Response (EDR) and incident remediation offerings.
At Cloudflare, we believe in making our solutions easily integrate with the existing technology stack of our customers. Through our partnerships and integrations, we make it easier for our customers to use Cloudflare solutions jointly with that of partners, to further strengthen their security posture and unlock more value. Our partnership with CrowdStrike is an apt example of such efforts.
Together, Cloudflare and CrowdStrike are working to simplify the adoption of Zero Trust for IT and security teams. With this expanded partnership, joint customers can identify, investigate, and remediate threats faster through multiple integrations:
First, by integrating Cloudflare’s Zero Trust services with CrowdStrike Falcon Zero Trust Assessment (ZTA), which provides continuous real-time device posture assessments, our customers can verify users’ device posture before granting them access to internal or external applications.
Second, we joined the CrowdXDR Alliance in December 2021 and are partnering with CrowdStrike to share security telemetry and other insights to make it easier for customers to identify and mitigate threats. Continue reading
So-Called Modern VPNs: Marketing and Reality
Someone left a “killer” comment1 after reading the Should We Use LISP blog post. It start with…
I must sadly say that your view on what VPN is all about is pretty rusty and archaic :( Sorry! Modern VPNs are all pub-sub based and are already turning into NaaS.
Nothing new there. I’ve been called old-school guru from an ivory tower when claiming TRILL is the wrong direction and we should use good old layer-3-based design2, but let’s unpack the “pub-sub” bit.

10 Reasons to Implement Network Automation – Low Effort, High Impact
In 2022, nearly 77% of technology professionals see the need for improvement in their data center network automation strategies. Despite years of predictions about applications and data migrating to the public cloud, a consensus has been that data centers remain the indispensable core of any digital infrastructure. While the public cloud has a vital role to play and it continues to grow, enterprises and service providers continue to rely on data centers to power their operations. To remain relevant in a cloud-centric world, data centers must modernize – needing scalable, efficient, and agile operations. Highly manual processes do not scale gracefully, therefore calling for organizations and their data centers to adopt network automation or be left behind.
VMware is proud to have an opportunity to sponsor Enterprise Management Associates (EMA) in producing The Future of Data Center Network Automation research report. This report analyzes cutting-edge technology of data center automation – drawing on quantitative and qualitative research done by EMA analysts – focusing on how tech orgs are planning, implementing, and using data center network automation solutions, the specific technologies they’re using, and the benefits and challenges associated with data center network automation.

Day Two Cloud 138: Rethinking Logs And Analysis With vRealize Log Insight Cloud (Sponsored)
VMware is our sponsor today for a Day Two Cloud episode about logging. Specifically, we're talking about vRealize Log Insight Cloud. It’s not just about collecting logs and events, and it's not just for VMware products. What do you get out of the data being logged? That’s what’s interesting. This is much more than a pile of syslogs with a search engine dropped on top.Announcing the Cloudflare API Gateway
Over the past decade, the Internet has experienced a tectonic shift. It used to be composed of static websites: with text, images, and the occasional embedded movie. But the Internet has grown enormously. We now rely on API-driven applications to help with almost every aspect of life. Rather than just download files, we are able to engage with apps by exchanging rich data. We track workouts and send the results to the cloud. We use smart locks and all kinds of IoT devices. And we interact with our friends online.
This is all wonderful, but it comes with an explosion of complexity on the back end. Why? Developers need to manage APIs in order to support this functionality. They need to monitor and authenticate every single request. And because these tasks are so difficult, they’re usually outsourced to an API gateway provider.
Unfortunately, today’s gateways leave a lot to be desired. First: they’re not cheap. Then there’s the performance impact. And finally, there’s a data and privacy risk, since more than 50% of traffic reaches APIs (and is presumably sent through a third party gateway). What a mess.
Today we’re announcing the Cloudflare API Gateway. We’re going to completely replace Continue reading
