Cloudflare, Inc. is an American internet infrastructure and security company founded in 2009 and publicly traded on the NYSE (ticker: NET) since 2019. The company operates one of the world's largest global networks — spanning 330+ cities in 120+ countries — and currently routes and protects approximately 20% of all global web traffic.
Cloudflare's mission is “to help build a better Internet” by making performance, security, and reliability accessible to organizations of every size — from individual developers using its free tier to Fortune 500 enterprises running their entire network connectivity through the platform. It is simultaneously a CDN, DDoS mitigation service, Zero Trust security platform, DNS provider, developer edge compute platform, and AI infrastructure layer.
Austin, Texas serves as one of Cloudflare's largest engineering and operations hubs globally — with thousands of engineers working across Cloudflare's network infrastructure, security products, and developer platform teams. The Austin office is among the company's biggest engineering concentrations outside San Francisco.
As of FY2024, Cloudflare generates approximately $1.67B in annual revenue, growing ~28% year-over-year, with 200,000+ paying customers and over 7 million total customers on its network. Approximately 80% of the top 50 generative AI companies run on Cloudflare infrastructure — making it a critical layer for AI application delivery.
Cloudflare's product surface has expanded far beyond its original CDN offering. The platform is organized across three major areas: Application Services (protecting and accelerating websites and APIs), Cloudflare One (enterprise network and security), and the Developer Platform (edge compute and data services).
CDN (Content Delivery Network)
Routes and caches content from 330+ global PoPs, reducing latency by serving assets from the edge nearest to each user. One of the world's largest CDNs by traffic volume.
DDoS Protection
Always-on, unmetered DDoS mitigation across all attack types and sizes. Cloudflare absorbed a 5.6 Tbps DDoS attack in 2024 — the largest recorded attack in history — without customer impact.
WAF (Web Application Firewall)
Protects web applications from SQL injection, XSS, and OWASP Top 10 attacks. Includes Cloudflare-managed rulesets updated continuously based on threats observed across the network.
DNS (1.1.1.1)
Cloudflare operates 1.1.1.1 — the world's fastest public DNS resolver (launched 2018). Also provides authoritative DNS for domains, serving trillions of DNS queries daily.
SSL / TLS
Free SSL for any website on Cloudflare, including Universal SSL. Cloudflare was the first company to make TLS 1.3 widely available and is the first SASE vendor to deploy post-quantum encryption.
ZTNA (Zero Trust Network Access)
Replaces VPN with identity-based access to internal applications. Cloudflare Access enforces per-request authentication at the edge — with no traffic hairpinning through a central data center.
Cloudflare Gateway (SWG)
DNS and HTTP filtering, threat intelligence, DLP, and CASB. Protects outbound employee traffic from malware, phishing, and shadow IT — including AI tools and SaaS apps.
Magic Transit
BGP-based network on-ramp that routes enterprise IP traffic through Cloudflare's global network for DDoS mitigation, traffic acceleration, and firewall services.
Magic WAN
Replaces MPLS and SD-WAN with Cloudflare's global private backbone. Connects branch offices, data centers, and cloud environments through a single network control plane.
Email Security
Cloud-native email phishing and business email compromise protection. Area 1 acquisition (2022) brought anti-phishing technology that blocks attacks before they reach the inbox.
Cloudflare Workers
Serverless edge compute platform running JavaScript, TypeScript, Python, and WebAssembly at 330+ locations globally with sub-millisecond cold-start times. Powers millions of applications and APIs.
Workers KV / Durable Objects
Global key-value store (KV) and strongly-consistent stateful objects (Durable Objects) for building distributed applications with persistent state at the edge.
R2 (Object Storage)
S3-compatible object storage with zero egress fees — Cloudflare's most direct challenge to AWS S3. R2 stores data across Cloudflare's network without charging for bandwidth out.
AI Gateway
Proxy layer for AI API calls (OpenAI, Anthropic, Workers AI) providing observability, caching, rate limiting, and cost controls. ~80% of top 50 GenAI companies use Cloudflare infrastructure.
Vectorize
Vector database for AI applications, enabling semantic search and RAG (retrieval-augmented generation) at the edge — tightly integrated with Workers AI and AI Gateway.
Cloudflare Pages
JAMstack deployment platform for frontend applications with global CDN delivery, preview deployments, and full-stack support via Workers integration.
Cloudflare's network is the foundation of all its products. Unlike traditional cloud providers that concentrate capacity in large regional data centers, Cloudflare deploys identical capabilities in 330+ cities in 120+ countries — meaning security processing, caching, and compute all happen within milliseconds of any end user on Earth.
Cloudflare's connectivity architecture is also unique in that the same physical infrastructure simultaneously serves CDN, security filtering, Zero Trust proxying, serverless compute, and DNS resolution — all from the same edge node. This co-location of services eliminates the latency penalties that plague competitors stitching together multi-vendor SASE stacks.
Austin is one of Cloudflare's largest engineering hubs globally — housing thousands of engineers and technical staff across network infrastructure, security engineering, the developer platform, and go-to-market functions.
Cloudflare made a deliberate choice to build a major presence in Austin as the city became increasingly competitive with San Francisco for engineering talent. The Austin office has grown significantly over the 2020–2025 period, tracking Austin's emergence as a major tier-1 US tech hub alongside the relocations of Oracle, Tesla, Dell's continued dominance, and Apple's $1B campus expansion.
Cloudflare's Austin engineering teams work on some of the company's most technically demanding problems — including the Workers runtime (a custom V8-based JavaScript execution environment running on hundreds of thousands of servers globally), network infrastructure for Cloudflare's 330+ PoPs, and Cloudflare One (SASE) product development.
Austin tech ecosystem impact: Cloudflare's Austin presence represents some of the highest-paying engineering roles in the city — its network infrastructure, security, and edge compute teams require deep systems programming expertise (Rust, C++, Go, V8 internals) that commands top-of-market compensation.
Matthew Prince, Michelle Zatlyn, and Lee Holloway found Cloudflare after a Harvard Business School project exploring how to make internet security and performance accessible to everyone — not just large enterprises.

As President, Zatlyn oversees revenue, go-to-market, and customer success. She is one of the most prominent female co-founders of a publicly traded US technology company and a frequent voice on entrepreneurship and internet policy.
Cloudflare competes across multiple product categories simultaneously — an unusual position that gives it both breadth advantages and competitive complexity.
Competitors: Akamai, Fastly, AWS CloudFront
Cloudflare's free tier and unified platform create significant adoption velocity against all three. Akamai is the incumbent enterprise CDN; Cloudflare has taken meaningful share.
Competitors: Zscaler, Palo Alto Prisma, Cisco SecureX, Netskope
Cloudflare One's 330+ PoP network gives it a latency advantage over Zscaler's ~150-node architecture. Gartner rated Cloudflare a "Visionary" (Zscaler is a "Leader") — reflecting Cloudflare's architectural advantage but smaller enterprise installed base.
Competitors: AWS Lambda@Edge, Vercel Edge Functions, Fastly Compute
Workers has sub-millisecond cold start (vs ~100ms+ for Lambda), runs at 330+ locations (vs AWS Lambda@Edge's ~20 regional edge nodes), and is significantly cheaper at scale.
Competitors: AWS S3, Google Cloud Storage, Backblaze B2
R2's zero-egress-fee model is a direct attack on AWS S3's ~$0.09/GB egress pricing. For high-traffic workloads, R2 can be dramatically cheaper despite similar object storage costs.
Competitors: AWS Bedrock, Vercel AI SDK, Modal
AI Gateway + Workers AI + Vectorize creates an end-to-end AI inference and retrieval stack at the edge. Cloudflare's position as network provider to ~80% of top GenAI companies gives it unique distribution.
