Security: WAF, DDoS and bots

Cloudflare blocks attacks before they reach your server.

📖 Key ideas

DDoS protection absorbs floods of traffic across the network.
The WAF (web application firewall) blocks SQL injection, XSS and known exploits.
Rate limiting caps requests per IP for login or API routes.
Bot management and Turnstile separate humans from bots.
Security events show what was blocked and why.

💡 Real-life example: Like a security guard at the gate who stops troublemakers, limits crowds and checks suspicious visitors.
