Cloudflare is a global network platform that provides security, performance, and reliability services for websites, applications, and enterprise networks. Its primary function is to protect websites from cyberattacks, improve loading speeds, and ensure higher content availability.

How Does Cloudflare Work?
Cloudflare acts as a reverse Proxy between users and web servers. When a visitor accesses a website protected by Cloudflare, their request first passes through Cloudflare’s network, which performs the following actions:

• Filtering Malicious Traffic – Protection against DDoS attacks, SQL injection, and other threats.
• Caching Content – Storing static website elements in a distributed server network (CDN) for faster loading times.
• Connection Optimization – Using compression and minification to enhance web performance.
• Data Encryption – Automatic HTTPS deployment with free SSL certificates.

Key Cloudflare Services
Cloudflare offers a wide range of services covering security, performance, and website reliability. Some of the core services include:

• CDN (Content Delivery Network) – A globally distributed network of servers that accelerates website loading speeds.
• DDoS Protection – Automatic detection and blocking of malicious attacks aimed at overwhelming web servers.
• WAF (Web Application Firewall) – Defense against SQL injection, XSS attacks, and other web application threats.
• DNS Services – Cloudflare operates some of the fastest DNS servers in the world, ensuring quick domain name resolution.
• Zero Trust Security – A set of tools that protect corporate applications and access systems based on a least-privilege model.
