Best WAF Website Firewall Solutions
Cyber Defense Isn’t Luck — Protect Your Website 24/7 with the Right AI WAF Partner
Tired of worrying about DDoS or hacker attacks? Yuan-Jhen Informationprovides the most trusted AI-WAF solutionson the market, helping you build a truly proactive web security defense line.
What Is a WAF and Why Do You Need One?
Cyberattacks are everywhere — from data breaches and system crashes to damaged SEO rankings — often caused by unseen security vulnerabilities.
A WAF (Web Application Firewall) acts as the gatekeeper in front of your website. It sits between the user and your web server, analyzing every HTTP/HTTPS request to detect abnormal traffic, attack patterns, and suspicious commands.
Unlike traditional firewalls that only block IPs or ports, a WAF focuses on the Application Layer (Layer 7). By combining AI threat intelligence and global security data, it identifies malicious intent hidden within web requests — blocking DDoS attacks, SQL injections, XSS exploits, and more — all without affecting your site’s performance.
Think of it as an AI-powered security guard who understands your website’s logic and risks, working tirelessly 24/7 to ensure every legitimate visitor reaches you safely.
How Does a WAF Protect Your Website? What Types of Attacks Can It Block?
Behind every website, there are countless hidden attack attempts happening every second. A WAF uses AI algorithms and threat databases to detect and block attacks before they reach your server, protecting your invisible security gaps. A WAF can defend against:
DDoS (Distributed Denial of Service)
Blocks abnormal high-volume traffic that aims to crash your website.
Layer 7 Attacks
Detects and mitigates HTTP Flood or Slowloris attacks that exhaust server resources.
SQL Injection
Stops malicious queries from altering or stealing your database content.
XSS (Cross-Site Scripting)
Prevents malicious scripts from stealing user data or hijacking browsers.
Malicious Bots / Automated Scanners
Blocks unauthorized crawlers that cause overload, data leakage, or SEO drops.
Brute-Force / API Abuse
Detects and blocks automated login attempts or over-used API calls.
A modern WAF doesn’t just “block” — it understands and reacts to attacks intelligently, ensuring maximum security without disrupting real users.
WAF vs. Traditional Firewall — What’s the Difference?
You might ask, “I already have a firewall, do I still need a WAF?” Yes — absolutely!
A traditional firewall only protects the Network Layer (Layer 3/4), managing packets, IPs, and connections. However, most modern attacks now target the Application Layer (Layer 7) — where your website logic and data live. That’s exactly where a WAF shines.
| Feature | Traditional Firewall | WAF (Web Application Firewall) |
|---|---|---|
| Protection Layer | Network / Transport (L3/L4) | Application (L7) |
| Attack Detection Accuracy | Low, IP-based filtering | High, behavioral & content analysis |
| Blocking Method | Static rules (e.g., IP blocking) | AI analysis + threat database |
| Traffic Analysis | Basic monitoring | Deep HTTP/S behavior inspection |
| Maintenance | Manual rule updates | Auto-learning + cloud updates |
| Deployment | Hardware-based, less flexible | Cloud or hybrid deployment |
| Ideal For | Internal corporate networks | All public websites, APIs, platforms |
