A big company helps the web.
They keep websites safe. They help websites work fast. This helps you see things online. It is very helpful for us. Do you use the web?
Cloudflare is a big tech company.
It helps keep the web safe. It also helps websites work fast. This happens by acting like a middleman. It stands between you and the website. This helps block bad traffic. They even use lava lamps for work! A camera watches the moving blobs. This helps make secret codes. It is a very cool way to work.
Cloudflare is a big technology company. It is based in San Francisco.
The company helps make the internet fast and safe. It acts as a reverse proxy. This means it stands between a visitor and a website. This helps block bad traffic. It also helps websites work better.
Cloudflare was started in 2009. Matthew Prince, Lee Holloway, and Michelle Zatlyn founded it. They chose the name to describe a "firewall in the cloud." A firewall is a tool that blocks bad things.
The company uses very neat tools. At their main office, they use lava lamps. A camera watches the moving blobs. This creates randomness for encryption keys. These keys are used to make secret codes.
Cloudflare also protects against DDoS attacks. These are attacks that try to crash a site. One huge attack in 2025 was very large. It was called "The Night Before Christmas." Cloudflare also helps schools stay safe online. They have a program for this. Many websites use Cloudflare today. About 21.3% of all websites use it.
Cloudflare is a large technology company based in San Francisco, California. It helps make the internet work better and stay safe for everyone. The company provides many services like a content delivery network, which helps websites load faster. It also offers cloud cybersecurity to protect data. One of its main jobs is acting as a reverse proxy. This means it stands between a website visitor and the hosting provider. This setup helps improve speed and blocks malicious traffic from reaching a site.
As of January 2026, about 21.3% of all websites use Cloudflare.
To keep information safe, Cloudflare uses a very clever way to create secret codes. They use a method called Lavarand to make encryption keys. At their headquarters, they have a wall of lava lamps. A camera watches the unpredictable shapes of the moving lava blobs. It turns these shapes into a digital image. This creates true randomness for the keys. They also use double pendulums in London and a Geiger counter in Singapore to get this randomness. This helps ensure that the digital locks on the internet stay strong.
Cloudflare was founded on July 26, 2009. Three people started the company: Matthew Prince, Lee Holloway, and Michelle Zatlyn. They chose the name Cloudflare because it described a "firewall in the cloud." A firewall is a tool used to block bad things. In 2019, the company went public on the New York Stock Exchange. It used the ticker symbol NET. Since then, the company has grown by buying many other tech companies. They have acquired groups like Area 1 Security and Replicate to add new tools.
One of the most important things Cloudflare does is stop DDoS attacks. A DDoS attack happens when many computers try to crash a website at once. These attacks can be huge. In 2023, Cloudflare blocked an attack with 71 million requests per second. In December 2025, a massive attack called "The Night Before Christmas" hit the telecommunications sector. This attack used a botnet named Aisuru. It reached a speed of 31.4 terabits per second. Cloudflare also helps people through Project Galileo. This program provides free protection for artists, journalists, and human rights groups.
Cloudflare is now using artificial intelligence to help manage the web. They launched Workers AI to let developers use powerful chips in their network. They also made a tool to stop bots from scraping websites. In 2025, they announced a feature called AI Labyrinth. This tool fights unauthorized data scraping by showing fake content to AI bots. They even have an AI assistant to help make charts. By using these new tools, Cloudflare helps keep the digital world organized and secure for all users.
Cloudflare, Inc. is a major American technology company based in San Francisco, California. It provides essential internet services that improve website performance and security. The company operates primarily as a reverse proxy. This means Cloudflare sits between a website visitor and the server where the website is hosted. By acting as a middleman, Cloudflare can speed up how content reaches users. It also protects websites from malicious traffic before it reaches the host. As of January 2026, Cloudflare is used by approximately 21.3% of all websites on the internet.
To understand how Cloudflare works, one must look at its core infrastructure. The company uses a content delivery network, or CDN, to serve content across its global network of servers. It supports many different transport layer protocols, such as TCP, UDP, and QUIC. It also handles application layer protocols like HTTP/2 and DNS over HTTPS. These technologies allow the company to manage a massive amount of data. In fact, Cloudflare handles an average of 45 million HTTP requests every single second. To power this heavy workload, its servers use AMD EPYC 9684X processors.
Cloudflare offers several distinct types of services for different needs. One major area is edge computing through its Workers platform. This is a serverless computing platform that lets developers create applications without managing their own hardware. They also offer Cloudflare Pages, which is a platform for deploying websites. For security, they provide DDoS mitigation to stop large-scale attacks. They also offer a public DNS resolver called 1.1.1.1 and a VPN service known as WARP. These tools help both large businesses and individual consumers stay connected and safe.
One of the company's most critical roles is mitigating Distributed Denial of Service (DDoS) attacks. A DDoS attack occurs when a massive number of computers attempt to crash a website at once. Cloudflare has defended against some of the largest attacks in internet history. In 2013, they helped defend The Spamhaus Project against an attack exceeding 300 gigabits per second. In July 2021, they absorbed an attack over 1.2 terabits per second. Most recently, in December 2025, they faced an attack called "The Night Before Christmas." This attack was launched by an Aisuru botnet and reached a massive 31.4 terabits per second.
Cloudflare has a long history of growth and evolution since its founding. Matthew Prince, Lee Holloway, and Michelle Zatlyn founded the company on July 26, 2009. They chose the name Cloudflare because it represented a "firewall in the cloud." The company went public on the New York Stock Exchange in 2019 under the ticker symbol NET. Since then, Cloudflare has grown by acquiring many specialized technology companies. These acquisitions include Area 1 Security in 2022 and Replicate in late 2025. These moves have allowed the company to expand into new fields like artificial intelligence.
Artificial intelligence is now a major part of Cloudflare's infrastructure. In 2023, they launched Workers AI, which lets developers use Nvidia GPUs within the Cloudflare network. They also created tools to manage how AI bots interact with websites. For example, they launched AI Audit to provide analytics on AI models scraping sites. In March 2025, they introduced a feature called AI Labyrinth. This tool combats unauthorized data scraping by serving fake, AI-generated content to LLM bots. These tools help website owners control how their data is used by automated systems.
Even the way Cloudflare secures data is unique and relies on physical randomness. To create strong encryption keys, the company uses a method called Lavarand. At their San Francisco headquarters, they use a wall of lava lamps for this purpose. A camera captures the unpredictable movement of the lava blobs and turns them into digital images. This creates the randomness needed for secure coding. They also use double pendulums in their London offices and Geiger counters in Singapore to achieve this same goal. This combination of physical science and digital technology helps keep the internet's most sensitive information secure.
