What Is Edge Security Service?

Edge Security (EdgeSec) is a security service based on the edge nodes of Huawei Cloud Content Delivery Network (CDN). It provides functions such as Edge Anti-DDoS, CC attack protection, Web Application Firewall (WAF), and bot behavior analysis. If you have purchased CDN or Whole Site Acceleration (WSA), you can enable security protection for acceleration domain names to safeguard content delivery.

ESA (Edge Security Acceleration) is a sub-product of EdgeSec. It provides cache acceleration and application security protection and supports multiple security functions, such as web attack defense, DDoS attack defense, and CC attack defense. ESA comprehensively improves the security protection capability of the acceleration network and ensures high-quality user experience and service security.

How It Works

When a user request reaches the EdgeSec acceleration network, the node identifies and intercepts various attack requests. EdgeSec supports anti-DDoS traffic cleaning. The EdgeSec engine analyzes the behavior of web, BOT, and CC attacks and updates interception policies to block malicious requests from reaching customers' origin servers, ensuring smooth and stable service access and implementing dynamic and static network acceleration.
