CDN & Global Acceleration
Cloudflare's CDN caches your content at every edge location, so users always load from a node within milliseconds of them. Argo Smart Routing finds the fastest network path in real time.
- Automatic static & dynamic caching at 330+ PoPs
- Argo Smart Routing — up to 30% faster than the public internet
- HTTP/3 & QUIC by default
- Image optimization and WebP conversion on the fly
- Cache Rules, Cache Reserve, and Tiered Caching
Argo
Smart routing over Cloudflare's private backbone.
Polish
Lossless & lossy image compression at the edge.
Rocket Loader
Async JavaScript loading to cut render-blocking.
Cache Reserve
Persistent R2-backed cache that never expires.
WAF & Bot Management
A single security layer that stops attacks, bots, and abuse before they reach your origin — without adding latency.
Web Application Firewall
OWASP Top 10, Cloudflare Managed Rules, and custom rules. Detect and block SQL injection, XSS, RCE and more — updated automatically.
Bot Management
Machine-learning bot scoring on every request. Challenge or block scrapers, credential stuffers and bad bots while letting good bots through.
Rate Limiting
Protect APIs and login forms from abuse with per-IP, per-session, or per-path rate limits — without touching your origin code.
API Shield
Validate API requests against your schema, stop data leakage, and enforce authentication at the edge.
Page Shield
Monitor third-party scripts and detect supply-chain attacks like Magecart before they steal user data.
Security Analytics
Full traffic telemetry — filter by ASN, country, path, or attack signature to understand your threat landscape.
Unmetered, Always-On DDoS Protection
Cloudflare's network absorbs DDoS attacks of any size at layers 3, 4 and 7 — automatically, without capping, and with no extra charge regardless of attack size.
- 195+ Tbps network capacity — largest in the industry
- Sub-3 second detection and mitigation at the edge
- L3/L4 protection via Magic Transit for IP infrastructure
- L7 HTTP flood protection via WAF & Rate Limiting
- Real-time attack analytics and traffic replays
195+ Tbps capacity
More than enough to absorb the largest DDoS attacks ever recorded — and growing.
The world's fastest authoritative DNS
Cloudflare DNS propagates changes globally in under 5 seconds and answers queries in a median of 11ms — faster than any other public DNS provider.
Authoritative DNS
Manage records for your domains. Sub-5s propagation, 100% uptime SLA on Enterprise.
DNSSEC
One-click DNSSEC signing to prevent DNS cache poisoning and spoofing attacks.
DNS Firewall
Proxy your resolver behind Cloudflare to block malicious domains and protect upstream servers.
1.1.1.1 Resolver
The world's fastest public resolver — private by design, no query logging.
Free, automatic HTTPS for every domain
Cloudflare issues and renews TLS certificates automatically, enforces modern cipher suites, and gives you fine-grained control over TLS versions and settings.
- Universal SSL — free cert for every domain, issued in seconds
- Advanced Certificates — multi-SANs, custom validity, wildcard
- TLS 1.3 and Encrypted Client Hello (ECH) by default
- mTLS for zero-trust API authentication
- SSL/TLS recommender to harden your configuration automatically
Minimum TLS Version → TLS 1.2 Cipher suites → Modern HSTS max-age → 31536000 Opportunistic ECH → Enabled mTLS enforcement → Enabled Certificate issued → 2s
Load Balancing & Health Checks
Route traffic across origins with geo-steering, failover, and weighted pools — all from Cloudflare's edge, without touching your infrastructure.
Global Load Balancing
Distribute traffic across origins in multiple regions with weighted, random, or geo-steered routing policies.
Health Checks
Continuous synthetic monitoring of your origins. Instant failover when a pool becomes unhealthy.
Geo Steering
Route users to the closest or best-performing region automatically — or pin traffic by country or region.
Session Affinity
Keep users pinned to the same origin for stateful applications with cookie-based affinity.
Protect and accelerate anything on the internet.
Add your domain to Cloudflare in under 5 minutes — DNS, CDN, and DDoS protection are active immediately.
