Give us a ping. (Cloudflare) One ping only.

Ping was born in 1983 when the Internet needed a simple, effective way to measure reachability and distance. In short, ping (and subsequent utilities like traceroute and MTR)  provides users with a quick way to validate whether one machine can communicate with another. Fast-forward to today and these network utility tools have become ubiquitous. Not only are they now the de facto standard for troubleshooting connectivity and network performance issues, but they also improve our overall quality of life by acting as a common suite of tools almost all Internet users are comfortable employing in their day-to-day roles and responsibilities.

Making network utility tools work as expected is very important to us, especially now as more and more customers are building their private networks on Cloudflare. Over 10,000 teams now run a private network on Cloudflare. Some of these teams are among the world's largest enterprises, some are small crews, and yet others are hobbyists, but they all want to know - can I reach that?

That’s why today we’re excited to incorporate support for these utilities into our already expansive troubleshooting toolkit for Cloudflare Zero Trust. To get started, sign up to receive beta access and start using the Continue reading

Cloudflare Zero Trust for managed service providers

As part of CIO week, we are announcing a new integration between our DNS Filtering solution and our Partner Tenant platform that supports parent-child policy requirements for our partner ecosystem and our direct customers. Our Tenant platform, launched in 2019, has allowed Cloudflare partners to easily integrate Cloudflare solutions across millions of customer accounts. Cloudflare Gateway, introduced in 2020, has grown from protecting personal networks to Fortune 500 enterprises in just a few short years. With the integration between these two solutions, we can now help Managed Service Providers (MSPs) support large, multi-tenant deployments with parent-child policy configurations and account-level policy overrides that seamlessly protect global employees from threats online.

Why work with Managed Service Providers?

Managed Service Providers (MSPs) are a critical part of the toolkit of many CIOs. In the age of disruptive technology, hybrid work, and shifting business models, outsourcing IT and security operations can be a fundamental decision that drives strategic goals and ensures business success across organizations of all sizes. An MSP is a third-party company that remotely manages a customer's information technology (IT) infrastructure and end-user systems. MSPs promise deep technical knowledge, threat insights, and tenured expertise across a variety Continue reading

Cloudflare Application Services for private networks: do more with the tools you already love

Cloudflare’s Application Services have been hard at work keeping Internet-facing websites and applications secure, fast, and reliable for over a decade. Cloudflare One provides similar security, performance, and reliability benefits for your entire corporate network. And today, we’re excited to announce new integrations that make it possible to use these services together in new ways. These integrations unlock operational and cost efficiencies for IT teams by allowing them to do more with fewer tools, and enable new use cases that are impossible without Cloudflare’s  “every service everywhere” architecture.

“Just as Canva simplifies graphic design, Cloudflare simplifies performance and security. Thanks to Cloudflare, we can focus on growing our product and expanding into new markets with confidence, knowing that our platform is fast, reliable, and secure.” - Jim Tyrrell, Head of Infrastructure, Canva

Every service everywhere, now for every network

One of Cloudflare’s fundamental architectural principles has always been to treat our network like one homogeneous supercomputer. Rather than deploying services in specific locations - for example, using some of our points of presence to enforce WAF policies, others for Zero Trust controls, and others for traffic optimization - every server runs a virtually identical stack of all of Continue reading

China Express: Cloudflare partners to boost performance in China for corporate networks

Cloudflare has been helping global organizations offer their users a consistent experience all over the world. This includes mainland China, a market our global customers cannot ignore but that continues to be challenging for infrastructure teams trying to ensure performance, security and reliability for their applications and users both in and outside mainland China. We are excited to announce China Express — a new suite of capabilities and best practices in partnership with our partners China Mobile International (CMI) and CBC Tech — that help address some of these performance challenges and ensure a consistent experience for customers and employees everywhere.

Cloudflare has been providing Application Services to users in mainland China since 2015, improving performance and security using in-country data centers and caching. Today, we have a presence in 30 cities in mainland China thanks to our strategic partnership with JD Cloud. While this delivers significant performance improvements, some requests still need to go back to the origin servers which may live outside mainland China. With limited international Internet gateways and restrictive cross-border regulations, international traffic has a very high latency and packet drop rate in and out of China. This results in inconsistent cached content within China and Continue reading

What to expect from SASE certifications

Secure access service edge (SASE) is a network architecture that rolls SD-WAN and security into a single, centrally-managed cloud service that promises simplified WAN deployment, improved security, and better performance.According to Gartner, SASE’s benefits are transformational because it can speed deployment time for new users, locations, applications, and devices, as well as reduce attack surfaces and shorten remediation times by as much as 95%.With the pandemic, adoption of SASE has been on an upward swing. Gartner predicts in its most recent SASE roadmap that 80% of enterprises will have adopted a SASE or SSE architecture by 2025, up from 20% in 2021. (Security service edge, or SSE, is a security-focused subset of SASE that’s basically SASE without SD-WAN.)To read this article in full, please click here

Addressing NetOps issues with Event-Driven Ansible

A simple example - No Shut, No Problem

Since the announcement of Event-Driven Ansible, I cannot stop thinking about potential use cases. Can I get events to automate scaling? Could I use a filesystem event to trigger filesystem integrity checks? Could I get a slackbot to trigger my choice of heavy metal playlist based on a “mood” event? It's all possible! But let’s not go too crazy, not yet. 

I started having a look at the fantastic work that one of our engineers, Nilashish Chakraborty has been doing around network telemetry and Ansible. This led me down the path to explore network events and what I could potentially do with something like Event-Driven Ansible. So let’s start with a super simple interface example.

Reaching out to the team at Arista, we started discussing and looking at the mechanisms they are using to get telemetry data. With Arista we are able to use gNMI, gNMI is an open source protocol specification created by the OpenConfig working group that is used to stream data to and from network devices. The OpenConfig working group operates as an open source project with contributions from network operators, equipment vendors in providing vendor-neutral Continue reading

Hedge 161: Going Dark with Geoff Huston

Encrypt everything! Now! We don’t often do well with absolutes like this in the engineering world–we tend to focus on “get it down,” and not to think very much about the side effects or unintended consequences. What are the unintended consequences of encrypting all traffic all the time? Geoff Huston joins Tom Ammon and Russ White to discuss the problems with going dark.

Using Pynetbox to Create Netbox API Tokens

As a warning to everyone, I am not a developer. I am a network engineer who is trying to do some automation stuff. Some of what I’m doing sounds logical to me, but I would not trust my own opinions for production work. I’m sure you can find a Slack channel or Mastodon instance with people who can tell you how to do things properly.

The last time, I talked about using pynetbox to make queries to Netbox. This was a very simple example, and one of the things that bugged me the most about it was the API token. In that post, we used a statically-assigned API token where I went into the Netbox GUI and generated one for myself. I think I may have even noted that this was definitely not the best way to handle those things. A possibly-better way to do it is to use your username and password on Netbox to generate a token for yourself. This would a token that you then delete when you’re done.

How is this better? The static tokens are just that — they’re static. If you generate your token, then anyone who has it can use it to Continue reading

Announcing SCIM support for Cloudflare Access & Gateway

Today, we're excited to announce that Cloudflare Access and Gateway now support the System for Cross-domain Identity Management (SCIM) protocol. Before we dive into what this means, let's take a step back and review what SCIM, Access, and Gateway are.

SCIM is a protocol that enables organizations to manage user identities and access to resources across multiple systems and domains. It is often used to automate the process of creating, updating, and deleting user accounts and permissions, and to keep these accounts and permissions in sync across different systems.

For example, most organizations have an identity provider, such as Okta or Azure Active Directory, that stores information about its employees, such as names, addresses, and job titles. The organization also likely uses cloud-based applications for collaboration. In order to access the cloud-based application, employees need to create an account and log in with a username and password. Instead of manually creating and managing these accounts, the organization can use SCIM to automate the process. Both the on-premise system and the cloud-based application are configured to support SCIM.

When a new employee is added to, or removed from, the identity provider, SCIM automatically creates an account for that employee in the Continue reading

Expanding our Microsoft collaboration: proactive and automated Zero Trust security for customers

As CIOs navigate the complexities of stitching together multiple solutions, we are extending our partnership with Microsoft to create one of the best Zero Trust solutions available. Today, we are announcing four new integrations between Azure AD and Cloudflare Zero Trust that reduce risk proactively. These integrated offerings increase automation allowing security teams to focus on threats versus implementation and maintenance.

What is Zero Trust and why is it important?

Zero Trust is an overused term in the industry and creates a lot of confusion. So, let's break it down. Zero Trust architecture emphasizes the “never trust, always verify” approach. One way to think about it is that in the traditional security perimeter or “castle and moat” model, you have access to all the rooms inside the building (e.g., apps) simply by having access to the main door (e.g., typically a VPN).  In the Zero Trust model you would need to obtain access to each locked room (or app) individually rather than only relying on access through the main door. Some key components of the Zero Trust model are identity e.g., Azure AD (who), apps e.g., a SAP instance or a custom Continue reading

New: Scan Salesforce and Box for security issues

Today, we’re sharing the release of two new SaaS integrations for Cloudflare CASB - Salesforce and Box - in order to help CIOs, IT leaders, and security admins swiftly identify looming security issues present across the exact type of tools housing this business-critical data.

Recap: What is Cloudflare CASB?

Released in September, Cloudflare’s API CASB has already proven to organizations from around the world that security risks - like insecure settings and inappropriate file sharing - can often exist across the friendly SaaS apps we all know and love, and indeed pose a threat. By giving operators a comprehensive view of the issues plaguing their SaaS environments, Cloudflare CASB has allowed them to effortlessly remediate problems in a timely manner before they can be leveraged against them.

But as both we and other forward-thinking administrators have come to realize, it’s not always Microsoft 365, Google Workspace, and business chat tools like Slack that contain an organization’s most sensitive information.

Scan Salesforce with Cloudflare CASB

The first Software-as-a-Service. Salesforce, the sprawling, intricate, hard-to-contain Customer Relationship Management (CRM) platform, gives workforces a flexible hub from which they can do just as the software describes: manage customer relationships. Whether it be tracking Continue reading

API-based email scanning

The landscape of email security is constantly changing. One aspect that remains consistent is the reliance of email as the beginning for the majority of threat campaigns. Attackers often start with a phishing campaign to gather employee credentials which, if successful, are used to exfiltrate data, siphon money, or perform other malicious activities. This threat remains ever present even as companies transition to moving their email to the cloud using providers like Microsoft 365 or Google Workspace.

In our pursuit to help build a better Internet and tackle online threats, Cloudflare offers email security via our Area 1 product to protect all types of email inboxes - from cloud to on premise. The Area 1 product analyzes every email an organization receives and uses our threat models to assess if the message poses risk to the customer. For messages that are deemed malicious, the Area 1 platform will even prevent the email from landing in the recipient's inbox, ensuring that there is no chance for the attempted attack to be successful.

We try to provide customers with the flexibility to deploy our solution in whatever way they find easiest. Continuing in this pursuit to make our solution as turnkey as Continue reading
