Cloudflare, Inc.

Overview

Cloudflare, Inc. is an American technology company headquartered in San Francisco, California. It provides a global cloud platform offering content delivery network (CDN) services, cybersecurity solutions, DDoS mitigation, domain registration, and developer tools. The company's services function primarily as a reverse proxy between website visitors and a customer's origin server, improving performance and protecting against malicious traffic.

As of early 2026, Cloudflare protects approximately 21.3% of all websites on the internet according to W3Techs data, making it one of the most ubiquitous pieces of internet infrastructure globally. The company operates in 330+ cities across 125+ countries — including mainland China — and blocks an average of 215 billion cyber threats per day. Cloudflare trades on the New York Stock Exchange under the ticker symbol NET.

History

Cloudflare was founded on July 26, 2009, by Matthew Prince, Lee Holloway, and Michelle Zatlyn. The idea originated in 2004 when Prince and Holloway began working on a project called Project Honey Pot — a distributed system designed to trace the source of email spam. The insights gained from that work laid the technical groundwork for what would become Cloudflare's core business of tracking and neutralizing malicious internet traffic at scale.

The company officially launched its services at TechCrunch Disrupt in September 2010, where it was named a finalist for the top startup award. The launch attracted immediate attention from the web community for offering enterprise-grade DDoS protection and performance optimization to websites of any size — including a free tier that made its tools accessible to independent publishers and small organizations.

Cloudflare went public on the New York Stock Exchange on September 13, 2019, raising approximately $525 million in its IPO at a price of $15 per share. The company has since grown into one of the largest internet infrastructure providers in the world, expanding through organic product development and targeted acquisitions including Area 1 Security (email security, acquired 2022) and Replicate (AI infrastructure).

Products and Services

Cloudflare's platform spans security, performance, networking, and developer tools — all delivered through its globally distributed edge network rather than from centralized data centers owned by the customer.

Security Solutions

Cloudflare's security portfolio is its largest and most widely known product area. It includes a Web Application Firewall (WAF), volumetric and application-layer DDoS mitigation, bot management, API security, and SSL/TLS encryption. The company also offers a suite of Zero Trust security products — including Cloudflare Zero Trust Network Access (ZTNA) and Secure Web Gateway (SWG) — designed to replace traditional corporate VPN architectures. These products operate under the Cloudflare One brand and are targeted at enterprises seeking to secure remote and hybrid workforces.

Performance and Delivery

Cloudflare's content delivery network caches and serves web content from the edge node closest to the requesting user, reducing latency and load on origin servers. The company also provides load balancing, global DNS services — including the public 1.1.1.1 resolver, which does not log user query data — video streaming infrastructure, and web optimization tooling including automatic image compression and minification.

Network Services

For enterprise and service provider customers, Cloudflare offers Magic WAN (SD-WAN replacement), Magic Transit (network-layer DDoS protection for on-premise and data center infrastructure), and Spectrum (TCP/UDP application proxy for non-HTTP traffic). These products are targeted at organizations seeking to eliminate traditional hardware-based network perimeters in favor of software-defined, cloud-native connectivity.

Developer Platform

Cloudflare Workers is the company's serverless and edge computing platform, allowing developers to deploy JavaScript, TypeScript, Python, and WebAssembly code that runs directly on Cloudflare's edge network — geographically close to users rather than in a single centralized region. Workers has been extended to support AI inference workloads, allowing developers to run models at the edge without managing GPU infrastructure. Other developer tools include Cloudflare Pages (static site hosting), R2 (object storage compatible with the S3 API), D1 (edge SQL database), and KV (distributed key-value storage).

Domain Services

Cloudflare is an ICANN-accredited domain registrar. Unlike most registrars, it offers domain registration at cost — without markup — to its customers, positioning domain services as a retention tool for its broader platform rather than a standalone revenue source.

Global Network

Cloudflare's edge network is among the largest in the world by number of interconnection points. As of early 2026, the network spans 330+ cities in 125+ countries, including locations in mainland China that operate under a separate compliance framework than Cloudflare's global infrastructure.

The company's network capacity is a key competitive differentiator. Cloudflare peers directly with thousands of internet service providers and major networks, allowing traffic from customer websites to be served with minimal hops from the network edge. The company's anycast routing architecture means that any request from a user is automatically directed to the nearest available Cloudflare node, regardless of where the customer's origin server is physically located.

This infrastructure also underlies Cloudflare's ability to absorb and neutralize distributed denial-of-service attacks at scale. By routing attack traffic through its global network rather than allowing it to reach customer origin servers, Cloudflare can mitigate volumetric attacks that would overwhelm any individual customer's infrastructure. The company reports blocking an average of 215 billion cyber threats per day as of early 2026.

Financials and Operations

Cloudflare reported $2.168 billion in revenue for fiscal year 2025, reflecting continued strong growth in its enterprise customer base and expansion of its Zero Trust and developer platform products. The company's GAAP gross margin reached 75% in FY 2025, consistent with a software-delivered infrastructure model where incremental costs are largely those of network capacity rather than physical hardware per customer.

Leadership

Cloudflare's executive team has remained stable since its founding, with both co-founders still in operating leadership roles — an unusual continuity for a company of Cloudflare's scale and public market tenure.

• Matthew Prince — Co-founder, Co-Chairman, and CEO. Prince co-created Project Honey Pot in 2004 alongside Lee Holloway, which led directly to founding Cloudflare. He has led the company from founding through IPO and its growth into a multi-billion-dollar public infrastructure company.
• Michelle Zatlyn — Co-founder, Co-Chair, and President. Zatlyn oversees the company's go-to-market, customer success, and business development functions. She joined Prince and Holloway as a co-founder after meeting Prince at Harvard Business School.
• Dane Knecht — Chief Technology Officer. Knecht leads Cloudflare's technical strategy and product architecture, including the evolution of the Workers platform and AI infrastructure capabilities.

Mission and Impact

Cloudflare's stated mission is "to help build a better Internet." The company positions itself as a connectivity cloud provider that makes websites, applications, AI agents, and networks faster and more secure, while reducing the complexity of managing traditional network hardware.
