Network performance update: Birthday Week 2023

We constantly measure our own network’s performance against other networks, look for ways to improve our performance compared to them, and share the results of our efforts. Since June 2021, we’ve been sharing benchmarking results we’ve run against other networks to see how we compare.

In this post we are going to share the most recent updates since our last post in June, and tell you about our tools and processes that we use to monitor and improve our network performance.

How we stack up

Since June 2021, we’ve been taking a close look at every single network and taking actions for the specific networks where we have some room for improvement. Cloudflare was already the fastest provider for most of the networks around the world (we define a network as country and AS number pair). Taking a closer look at the numbers; in July 2022, Cloudflare was ranked #1 in 33% of the networks and was within 2 ms (95th percentile TCP Connection Time) or 5% of the #1 provider for 8% of the networks that we measured. For reference, our closest competitor on that front was the fastest for 20% of networks.

As of August 30, Continue reading

See what threats are lurking in your Office 365 with Cloudflare Email Retro Scan

We are now announcing the ability for Cloudflare customers to scan old messages within their Office 365 Inboxes for threats. This Retro Scan will let you look back seven days and see what threats your current email security tool has missed.

Why run a Retro Scan

Speaking with customers, we often hear that they do not know the condition of their organization’s mailboxes. Organizations have an email security tool or use Microsoft’s built-in protection but do not understand how effective their current solution is. We find that these tools often let malicious emails through their filters increasing the risk of compromise within the company.

In our pursuit to help build a better Internet, we are enabling Cloudflare customers to use Retro Scan to scan messages within their inboxes using our advanced machine learning models for free. Our Retro Scan will detect and highlight any threats we find so that customers can clean up their inboxes by addressing them within their email accounts. With this information, customers can also implement additional controls, such as using Cloudflare or their preferred solution, to prevent similar threats from reaching their mailbox in the future.

Detecting zero-days before zero-day

We are constantly researching ways to improve our products. For the Web Application Firewall (WAF), the goal is simple: keep customer web applications safe by building the best solution available on the market.

In this blog post we talk about our approach and ongoing research into detecting novel web attack vectors in our WAF before they are seen by a security researcher. If you are interested in learning about our secret sauce, read on.

This post is the written form of a presentation first delivered at Black Hat USA 2023.

The value of a WAF

Many companies offer web application firewalls and application security products with a total addressable market forecasted to increase for the foreseeable future.

In this space, vendors, including ourselves, often like to boast the importance of their solution by presenting ever-growing statistics around threats to web applications. Bigger numbers and scarier stats are great ways to justify expensive investments in web security. Taking a few examples from our very own application security report research (see our latest report here):

The numbers above all translate to real value: yes, a large portion of Internet HTTP traffic is malicious, therefore you could mitigate a non-negligible amount Continue reading

Post-quantum cryptography goes GA

Over the last twelve months, we have been talking about the new baseline of encryption on the Internet: post-quantum cryptography. During Birthday Week last year we announced that our beta of Kyber was available for testing, and that Cloudflare Tunnel could be enabled with post-quantum cryptography. Earlier this year, we made our stance clear that this foundational technology should be available to everyone for free, forever.

Today, we have hit a milestone after six years and 31 blog posts in the making: we’re starting to roll out General Availability¹ of post-quantum cryptography support to our customers, services, and internal systems as described more fully below. This includes products like Pingora for origin connectivity, 1.1.1.1, R2, Argo Smart Routing, Snippets, and so many more.

This is a milestone for the Internet. We don't yet know when quantum computers will have enough scale to break today's cryptography, but the benefits of upgrading to post-quantum cryptography now are clear. Fast connections and future-proofed security are all possible today because of the advances made by Cloudflare, Google, Mozilla, the National Institutes of Standards and Technology in the United States, the Internet Engineering Task Force, and numerous academic institutions

Sehen Sie, welche Bedrohungen in Ihrem Office 365 lauern – mit dem Retro Scan von Cloudflare für E-Mails

Ab sofort können Cloudflare-Kunden alte Nachrichten in ihren Office 365-Postfächern auf Bedrohungen hin scannen. Mit dem Retro Scan können Sie jeweils die vergangenen sieben Tage überprüfen, um zu sehen, welche Bedrohungen Ihrem aktuellen E-Mail-Sicherheitstool entgangen sind.

Gründe für den Einsatz eines Retro Scan

Kunden berichten uns oft, dass sie nicht wissen, in welchem Zustand die E-Mail-Postfächer ihrer Unternehmen sind. Firmen nutzen ein E-Mail-Sicherheitstool oder den bei Microsoft integrierten Schutz. Oft ist wissen sie aber nicht, wie effektiv ihre aktuelle Lösung tatsächlich arbeitet. Wir haben festgestellt, dass schädliche E-Mails von diesen Werkzeugen oft nicht herausgefiltert werden, wodurch sich das Risiko einer Kompromittierung innerhalb des Unternehmens erhöht.

Im Rahmen unserer Bemühungen, ein besseres Internet zu schaffen, stellen wir Cloudflare-Kunden nun einen Retro Scan zur Verfügung. Mit diesem können sie Nachrichten in ihren Postfächern unter Einsatz fortschrittlicher Machine Learning-Modelle kostenlos scannen. Unser Retro Scan erkennt Bedrohungen und weist auf diese hin, sodass Kunden ihre Postfächer durch eine Behebung innerhalb ihrer E-Mail-Konten bereinigen können. Mit diesen Informationen sind sie außerdem in der Lage, herkömmliche Kontrollen zu implementieren. Sie können also Cloudflare oder ihre bevorzugte Lösung einsetzen, um vergleichbare Bedrohungen in Zukunft daran zu hindern, ihre Postfach überhaupt erst zu erreichen.

클라우드, 네트워크, 애플리케이션 및 사용자를 연결하고 보호하는 현대적인 방법인 클라우드 연결성으로 여러분을 모십니다

우리가 근무하면서 가장 좋아하는 부분은 Cloudflare 고객과 대화하는 시간입니다. 고객의 IT 및 보안 문제에 대하여 항상 새롭고 흥미로운 사실을 알게 됩니다.

최근 이러한 대화에 변화가 있었습니다. 고객이 언급하는 가장 큰 문제를 쉽게 정의할 수 없는 경우가 점점 더 많아집니다. 그리고 이러한 문제는 개별 제품이나 주요 기능으로 대처할 수 없는 것입니다.

더 정확히 말하면 IT 및 보안 팀에서는 디지털 환경에 대한 제어 능력을 잃고 있다고 이야기합니다.

제어 능력 상실은 다양한 형태를 띱니다. 고객은 호환성이 걱정되므로 필요성은 알지만 새로운 기능을 채택하는 것을 꺼리는 모습을 보일 수 있습니다. 아니면 비교적 단순한 변경 사항을 적용하는 데 시간과 노력이 많이 들며, 이러한 변경 사항 때문에 더 큰 영향력이 있을 작업에 투입할 시간을 빼앗기고 있다고 언급할 수도 있습니다. 고객이 느끼는 감정을 요약하자면 "팀이나 예산의 규모가 아무리 크더라도 비즈니스를 완벽하게 연결하고 보호하는 데는 절대 충분하지 않다"는 것입니다.

익숙하게 느껴지는 부분이 있으신가요? 그런 부분이 있다 해도 여러분 혼자 그렇게 느끼는 건 아닙니다.

제어 능력을 상실하는 이유

IT 및 보안이 바뀌는 속도는 빨라지고 있으며 무섭도록 복잡해지고 있습니다. IT 및 보안 팀에서는 과거에 비해 더 다양한 기술 도메인을 책임지고 있습니다. 최근 Forrester 연구에서 확인된 변화에 따르면 사내, 원격, 하이브리드 근무자를 보호할 책임이 있는 팀의 52%만이 지난 5년 동안 이러한 책임을 맡았습니다. 한편 46%는 해당 기간 동안 퍼블릭 클라우드 애플리케이션을 Continue reading

Cloudflare is free of CAPTCHAs; Turnstile is free for everyone

For years, we’ve written that CAPTCHAs drive us crazy. Humans give up on CAPTCHA puzzles approximately 15% of the time and, maddeningly, CAPTCHAs are significantly easier for bots to solve than they are for humans. We’ve spent the past three and a half years working to build a better experience for humans that’s just as effective at stopping bots. As of this month, we’ve finished replacing every CAPTCHA issued by Cloudflare with Turnstile, our new CAPTCHA replacement (pictured below). Cloudflare will never issue another visual puzzle to anyone, for any reason.

Now that we’ve eliminated CAPTCHAs at Cloudflare, we want to make it easy for anyone to do the same, even if they don’t use other Cloudflare services. We’ve decoupled Turnstile from our platform so that any website operator on any platform can use it just by adding a few lines of code. We’re thrilled to announce that Turnstile is now generally available, and Turnstile’s ‘Managed’ mode is now completely free to everyone for unlimited use.

Easy on humans, hard on bots, private for everyone

There’s a lot that goes into Turnstile’s simple checkbox to ensure that it’s easy for everyone, preserves user privacy, and does its job stopping bots. Continue reading

Easily manage AI crawlers with our new bot categories

Today, we’re excited to announce that any Cloudflare user, on any plan, can choose specific categories of bots that they want to allow or block, including AI crawlers.

As the popularity of generative AI has grown, content creators and policymakers around the world have started to ask questions about what data AI companies are using to train their models without permission. As with all new innovative technologies, laws will likely need to evolve to address different parties' interests and what’s best for society at large. While we don’t know how it will shake out, we believe that website operators should have an easy way to block unwanted AI crawlers and to also let AI bots know when they are permitted to crawl their websites.

The good news is that Cloudflare already automatically stops scraper bots today. But we want to make it even easier for customers to be sure they are protected, see how frequently AI scrapers might be visiting their sites, and respond to them in more targeted ways. We also recognize that not all AI crawlers are the same and that some AI companies are looking for clear instructions for when they should not crawl a public website.

Ansible Contributor Summit, Durham 2023

Ansible Contributor Summit, Durham 2023

The Ansible Contributor Summit is a full day working session for community contributors to interact with one another and meet with the Ansible development teams behind the projects like AWX, Galaxy NG, Molecule, Ansible Lint and Event-Driven Ansible. We will discuss important issues affecting the Ansible Community and help shape the future of collaboration.

We are happy to have the opportunity to do a second Contributor Summit this year, and this time it will be part of DjangoCon US 2023 in Durham, NC. Our previous experience co-locating the Contributor Summit with another related event was in February in Ghent, Belgium as part of CfgMgmtCamp 2023. It was so successful, we wanted to do it again with another great match.

Hello, Durham!

We will be meeting in the "Bull City", the home of Ansible itself and the inspiration for our beloved mascot, Ansibull. In case you didn't know, the Ansible office overlooks the Durham Bulls Athletic Park, and this mixed with Ansible word play is why you might see mentions of bulls and Ansibulls in Ansible land.

If you can't attend the event in person in Durham, worry not! Ansible Contributor Summit is a hybrid event, Continue reading

BrandPost: Securing AWS cloud environments

The benefits of moving workloads into a cloud-based environment cannot be overstated. AWS, for instance, is designed for flexibility, allowing users to select the operating system, programming language, web application platform, database, and other services to suit their own specific needs. This adaptability not only simplifies the migration process for existing applications but also provides a strong foundation for building new solutions.However, there is a flip side. With this flexibility comes the potential for an AWS customer to unknowingly introduce risks into their cloud environment. One of the most significant risks is the formation of attack paths, which can be used by malicious actors to infiltrate and compromise cloud resources. These exposed paths emerge through a combination of factors that are often easy to overlook in a complex and fast-moving cloud environment. They are best summarized in three distinct categories:To read this article in full, please click here
