The Content Delivery Network (CDN) Aspect

Imagine your website’s files (like images, videos, CSS, and JavaScript) stored on a server in one location – say, New York. If someone in London tries to access your site, those files have to travel all the way across the Atlantic. That takes time, and the further the distance, the slower your site might feel.

This is where the CDN comes in. CloudFilt has a vast global network of servers, known as Points of Presence (PoPs), spread out across the world. We’re talking over 340 of them! Here’s what happens when you use CloudFilt’s CDN:

1. Content Caching: When a user first visits your website, CloudFilt’s CDN caches, or temporarily stores, copies of your website’s static content (like images, videos, and certain scripts) on these geographically distributed PoPs.
2. Closest Server Delivery: The next time someone requests that content, CloudFilt intelligently directs their request to the nearest PoP that has a cached copy. So, our London user would get the content from a server in London or a nearby city, not all the way from New York. This drastically reduces the physical distance the data has to travel, leading to much faster loading times.
3. Reduced Server Load: Because many requests are handled by the CDN’s edge servers, your main origin server doesn’t have to work as hard. This frees up its resources, making your website more stable and responsive, especially during peak traffic.
4. High Availability: If one server or network segment experiences an issue, the CDN can automatically route traffic to another healthy server, ensuring your website remains accessible.

The Web Application Firewall (WAF) Aspect

While the CDN is all about speed, the WAF is your website’s dedicated bodyguard. It sits in front of your web application, analyzing all incoming traffic before it reaches your server.

Here’s the step-by-step security process:

1. Traffic Interception: When a user or bot tries to access your website, their request first goes through CloudFilt’s WAF. This is done by simply updating your domain’s DNS records to point to CloudFilt’s servers.
2. Real-Time Analysis (AI-Powered): The WAF doesn’t just look for known signatures of attacks. CloudFilt’s WAF uses artificial intelligence, behavioral analysis, and a continuously updated IP reputation database. It examines every request for:
   • Malicious patterns: It identifies common web vulnerabilities like SQL injection, cross-site scripting (XSS), and other hacking attempts.
   • Bot behavior: It distinguishes between legitimate human users and various types of bots, including scrapers, spammers, and those attempting brute-force attacks. It looks for unusual patterns, speeds, and interactions.
   • IP reputation: It checks if the source IP address has a history of malicious activity.
3. Threat Mitigation at the Edge: If a request is deemed malicious or suspicious, the WAF blocks it instantly, right at the network edge. This means the bad traffic never even reaches your server, which saves your server’s resources and prevents potential damage or slowdowns.
4. Custom Rules and Controls: While the AI does a lot of the heavy lifting, you can also set up your own custom rules. This allows you to whitelist specific IP addresses, block certain countries, or implement CAPTCHA challenges for specific actions.
5. Real-Time Monitoring and Alerts: Everything the WAF does is logged and displayed in your CloudFilt dashboard. You get real-time analytics and alerts for suspicious activity, giving you a clear picture of security events and allowing you to respond proactively.

In essence, CloudFilt CDN WAF funnels all your website traffic through its intelligent network. The good traffic gets accelerated and delivered quickly, while the bad traffic gets detected and blocked, ensuring a faster, safer, and smoother experience for your legitimate users.
