Cloudflare WAF Solution – Comprehensive Website & API Protection for Enterprises

Overview of current web application threats

Along with the strong development of the Internet, website attack methods are increasingly sophisticated and occur with high frequency. Hackers not only target network infrastructure, but focus on exploiting vulnerabilities at the application layer (Layer 7 – Application Layer) to gain system control, steal data or disrupt services.

Common attack techniques include:

  • SQL Injection

  • Cross-Site Scripting (XSS)

  • Credential stuffing

  • Brute force

  • Zero-day exploit

Main causes stem from:

  • Lack of dedicated application security testing team

  • Pressure to deploy quickly, skipping security testing

  • Unable to control all malicious requests manually

👉 This is why Web Application Firewall (WAF) has become a mandatory defense layer in modern security architecture.

WAF – Web Application Firewall là gì?

 

Web Application Firewall (WAF) is a specialized security solution that helps:

  • Analyze entire HTTP/HTTPS requests

  • Detect & prevent attacks targeting web applications and APIs

  • Protect data and ensure service availability

Unlike traditional firewalls, WAF focuses on protecting application logic, where the most sophisticated attacks occur.
