CDNs, or content delivery networks, ensure that digital content is delivered to end users not directly but through geographically distributed data points. The geographical distribution of data points ensures that users consistently access content from the closest source, with very low latency.
When you use WAF solutions combined with CDNs, malicious traffic is detected and blocked at a much further point from your main server. Secure CDNs that offer an advanced WAF solution, both strengthen your security posture and reduce the load on the source server.
