Intelligent Web Application Firewall for Comprehensive Security
AI-based semantic analysis engine for precise detection of SQL injection, XSS, command injection, path traversal, and other web attacks in real-time.
Dynamic parameter encryption with signature verification and timestamp checks to prevent MITM attacks, data tampering, and replay attacks, protecting API communication security.
Intelligent detection of malicious crawlers, automation tools, and AI bots. Uses behavior analysis and CAPTCHA to distinguish legitimate users from malicious bots.
Flexible custom rule engine supporting IP blacklists/whitelists, URL path control, referer validation, and User-Agent filtering for fine-grained access control policies.
Intelligent detection of CC and slow attacks. Auto-triggers protection based on rate limiting and sliding window algorithms with CAPTCHA challenges and smart blocking.
IP geolocation-based access control by country/province/city for compliance and regional routing. Supports custom geo-restriction rules.
Technical details about ZyCDN self-hosted CDN WAF firewall.
ZyCDN includes a semantic WAF firewall using an AI-based analysis engine for deep HTTP request inspection. Unlike regex-based WAFs, the semantic WAF understands request context to accurately detect SQL injection, XSS, command injection, and path traversal attacks while reducing false positives. WAF rules are flexibly configured through the console with custom rules and protection template management.
ZyCDN provides multi-layer CC protection: base layer detects abnormal request frequency through rate limiting and sliding window algorithms; enhanced layer supports CAPTCHA/waiting room to verify visitor identity; intelligent layer uses AI behavioral analysis to identify automation tools. The system auto-adjusts protection based on attack intensity to minimize impact on legitimate users.
ZyCDN bot protection supports crawler detection, automation detection, CAPTCHA verification, and behavioral analysis. It distinguishes legitimate users from malicious bots by analyzing request characteristics, access frequency, mouse/keyboard behavior, and other dimensions. Custom bot rules support different protection policies per URL path. AI crawler detection prevents training data scraping.
