Cloudflare’s Bot Management is used by organizations around the world to proactively detect and mitigate automated bot traffic. To do this, Cloudflare leverages machine learning models that help predict whether a particular HTTP request is coming from a bot or not, and further distinguishes between benign and malicious bots. Cloudflare serves over 55 million HTTP requests per second — so our machine learning models need to run at Cloudflare scale.

As more organizations collectively progress toward adopting a SASE architecture, it has become clear that the traditional SASE market definition (SSE + SD-WAN) is not enough. It forces some teams to work with multiple vendors to address their specific needs, introducing performance and security tradeoffs. More worrisome, it draws focus more to a checklist of services than a vendor’s underlying architecture.

Just in time for Data Privacy Day 2024 on January 28, the EU Commission is calling for evidence to understand how the EU’s General Data Protection Regulation (GDPR) has been functioning now that we’re nearing the 6th anniversary of the regulation coming into force. We’re so glad they asked, because we have some thoughts. And what better way to celebrate privacy day than by discussing whether the application of the GDPR has actually done anything to improve people’s privacy?

Most WAF providers rely on reactive methods, responding to vulnerabilities after they have been discovered and exploited. However, we believe in proactively addressing potential risks, and using AI to achieve this. Today we are sharing a recent example of a critical vulnerability (CVE-2023-46805 and CVE-2024-21887) and how Cloudflare's Attack Score powered by AI, and Emergency Rules in the WAF have countered this threat.

Welcome to the sixteenth edition of Cloudflare’s DDoS Threat Report. This edition covers DDoS trends and key findings for the fourth and final quarter of the year 2023, complete with a review of major trends throughout the year.

You may know Cloudflare as the company powering nearly 20% of the web. But powering and protecting websites and static content is only a fraction of what we do. In fact, well over half of the dynamic traffic on our network consists not of web pages, but of Application Programming Interface (API) traffic — the plumbing that makes technology work.

The challenge of telling humans and bots apart is almost as old as the web itself. From online ticket vendors to dating apps, to ecommerce and finance — there are many legitimate reasons why you'd want to know if it's a person or a machine knocking on the front door of your website. Unfortunately, the tools for the web have traditionally been clunky and sometimes involved a bad user experience.

Many applications rely on user data to deliver useful features. For instance, browser telemetry can identify network errors or buggy websites by collecting and aggregating data from individuals. However, browsing history can be sensitive, and sharing this information opens the door to privacy risks. Interestingly, these applications are often not interested in individual data points (e.g.

As the last school bell rings before winter break, one thing school districts should keep in mind is that during the winter break, schools can become particularly vulnerable to cyberattacks as the reduced staff presence and extended downtime create an environment conducive to security lapses. Criminal actors make their move when organizations are most vulnerable: on weekends and holiday breaks.

Two months ago, we made Cloudflare Turnstile generally available — giving website owners everywhere an easy way to fend off bots, without ever issuing a CAPTCHA. Turnstile allows any website owner to embed a frustration-free Cloudflare challenge on their website with a simple code snippet, making it easy to help ensure that only human traffic makes it through.
