We created the Cloudflare Codex, a governed body of engineering standards that AI agents consume across the development lifecycle. By pairing structured RFCs with agentic reviews, teams automatically enforce consistency across code, specs, and incident reports.
Cloudflare Workers has had a very busy 2018. Throughout the year, Workers moved from beta to general availability, continued to expand its footprint as Cloudflare grew to 155 locations, and added new features and services to help developers create increasingly advanced applications.
Today, v2 of Pwned Passwords was released as part of the Have I Been Pwned service offered by Troy Hunt. Containing over half a billion real world leaked passwords, this database provides a vital tool for correcting the course of how the industry combats modern threats against password security.
Both in our real lives, and online, there are times where we need to authenticate ourselves - where we need to confirm we are who we say we are. This can be done using three things.
For some businesses SEO is a bad word, and for good reason. Google and other search engines keep their algorithms a well-guarded secret making SEO implementation not unlike playing a game where the referee won’t tell you all the rules.
In April, we wrote about Web Cache Deception attacks, and how our customers can avoid them using origin configuration. Since our previous blog post, we have looked for but have not seen any large scale attacks like this in the wild.
Today, December 25th, Cloudflare offices around the world are taking a break. From San Francisco to London and Singapore; engineers have retreated home for the holidays (albeit with those engineers on-call closely monitoring their mobile phones).
Brady Gentile from Cloudflare's product team wrote an App Developer Playbook, embedded within the developer documentation page.
Earlier this year, Cloudflare Apps was launched so app developers may leverage our global network of 6 million+ websites, applications, and APIs.
Cloudflare’s community of users is vast. With more than 6 million domains registered, our users come in all shapes and sizes and are located all over the world.
Cloudflare provides numerous benefits to ecommerce sites, including advanced DDOS protection and an industry-leading Web Application Firewall (WAF) that helps secure your transactions and protect customers’ private data.
About a month ago, security researcher Omer Gil published the details of an attack that he calls the Web Cache Deception attack. It works against sites that sit behind a reverse proxy (like Cloudflare) and are misconfigured in a particular way.
The North American Network Operators Group (NANOG) is the loci of modern Internet innovation and the day-to-day cumulative network-operational knowledge of thousands and thousands of network engineers.
Microservices is one of the buzz words of the moment. Beyond the buzz, microservices architecture offers a great opportunity for developers to rethink how they design, develop, and secure applications.
I was asked to debug another weird issue on our network. Apparently every now and then a connection going through CloudFlare would time out with 522 HTTP error.
Everything that it's possible to do in the CloudFlare Dashboard is also possible through our RESTful API. We use the same API to power the dashboard itself.
Two years ago we blogged about our love of BPF (BSD packet filter) bytecode. Today we are very happy to open source another component of the bpftools: our p0f BPF compiler!
The Go test coverage implementation is quite ingenious: when asked to, the Go compiler will preprocess the source so that when each code portion is executed a bit is set in a coverage bitmap.
