Tadu WAF

When a server handles hundreds of websites, you need more than one security plugin. In a world where thousands of automated scans target WordPress websites every day—from aggressive AI scraper bots and webshells hidden in uploaded files to unexpected DDoS attacks—a superficial protection solution is no longer enough. You need a true "gatekeeper": fast, intelligent, and never-sleeping. Tadu WAF — Vovinam Engine v2.0 is the answer. 🔥 A smart firewall tailored specifically for WordPress Developed by the Tadu.cloud team, Tadu WAF is a high-performance Web Application Firewall solution that can protect hundreds of websites on the same server with less than 1 millisecond of latency per request. Unlike traditional WAFs that often consume resources and slow down websites, Vovinam Engine is optimally designed, compact, and operates in real time — detecting and blocking attacks before they reach your application. The numbers speak for themselves: ⚡ 13 layers of parallel security filtering, no bottleneck 🚀 < 1ms additional latency per request 🌐 1 million+ IP blacklists lookup in O(1) 🦠 100+ webshell signatures recognized 🎯 Comprehensive protection — No blind spots 1. Multi-layered WAF Engine Detects SQL Injection, XSS, PHP Code Injection, LFI/RFI in every corner of the request: query string, header, cookie, body. No attacker can "circumvent" the rules. 2. Intelligent GeoIP & Blacklist Blocking by country and over 1 million malicious IPs are automatically updated every 24–48 hours from reputable security intelligence sources. Hackers are blocked before they even start. 3. Advanced Bot Detection With JavaScript fingerprinting, Tadu WAF clearly distinguishes between real users, legitimate bots (Googlebot), and attack bots. In particular, it blocks all AI scrapers like GPTBot, Claude, and Bytespider—protecting your content from being "blood-sucking" and trained by AI. 4. 3-Layer Upload & Malware Scanning ✅ File name verification (regex + heuristic) ✅ MIME type verification via magic bytes ✅ Content analysis via fuzzy hash—detects even variant malware 5. Anti-DDoS & Tarpit Token bucket rate limiting by domain. When an unusual traffic surge is detected, the system automatically activates "under attack mode". The Tarpit feature also slows down attackers when they try to reconnect—turning them into prey for the trap itself. 6. Advanced Webshell Detection Dictionary of 100+ popular webshells, combining regex (hex names, double extensions) and consonant cluster analysis to detect spoofing filenames without vowels—even the most sophisticated tricks are exposed. 7. Ultra-Secure Authentication Login via Linux account, RSA-encrypted password directly on the client side. Session opaque—not a single byte of user information is exposed in cookies. 8. Real-time Monitoring Dashboard CPU, RAM, Disk, and traffic graphs update every 5 seconds. A world map shows attack IPs by country—you can see every attack and block by the system. 🧠 13-Layer Pipeline — From Cheap to Expensive The design philosophy of Vovinam Engine is clear: each request only goes through the necessary layers, starting from the cheapest checks (hash lookup O(1)) to deeper analyses. The result? Maximum server resource savings, no impact on website performance, but extremely strict security.
