Want to see how SafeLine WAF defends against the OWASP Top 10 without deploying it yourself? You're in luck — SafeLine offers a live public demo server that you can attack directly, making testing incredibly easy and fast.
🌐 What is SafeLine WAF?
SafeLine is one of the most popular self-hosted Web Application Firewalls in 2025 — and for good reason. With a powerful semantic analysis engine, zero false positive tuning out-of-the-box, and a free tier that supports 10 protected applications, it’s ideal for developers, homelabbers, and security enthusiasts.
Now let’s get into how to test it.
Step-by-Step: Test SafeLine WAF Live
You don’t need to install anything. SafeLine provides a public-facing demo environment:
- Demo Application:
https://demo.waf.chaitin.com:10084/hello.html - Testing Console:
https://demo.waf.chaitin.com/
You can use common tools like:
- OWASP ZAP
- Burp Suite
- wstester or curl
- Online testing utilities
Important: All traffic is monitored. Use only for security testing. Do not abuse.
Test Cases Against OWASP Top 10
Here are some simple payloads to try on the demo site:
1. Injection (SQLi)
curl 'https://demo.waf.chaitin.com:10084/hello.html?user=1%20AND%201=1'
Expected: Blocked with a challenge or deny page.
2. Broken Authentication
Try brute-forcing with a simple script or use test credentials.
Expected: Rate limiting or CAPTCHA challenge.
3. Sensitive Data Exposure
Attempt to inspect headers or inject parameters that might bypass controls.
Expected: Sanitized responses, encrypted content.
4. XML External Entities (XXE)
Use a crafted XML upload if the endpoint supports XML parsing.
Expected: Blocked or sanitized.
5. Broken Access Control
Try modifying parameters like ?user_id=2 as an unauthorized user.
Expected: Response blocked or challenged.
6. Security Misconfiguration
Scan the headers using tools like curl -I.
Expected: Secure headers like Content-Security-Policy, X-Frame-Options, etc.
7. Cross-Site Scripting (XSS)
curl 'https://demo.waf.chaitin.com:10084/hello.html?msg=<script>alert(1)</script>'
Expected: Blocked or sanitized.
8. Insecure Deserialization
Try tampering with cookies or serialized payloads.
Expected: Challenge or blocking.
9. Using Vulnerable Components
Scan with tools like OWASP Dependency-Check (demo doesn’t reflect backend stack).
10. Insufficient Logging & Monitoring
Check responses from repeated access attempts or abuse.
What Makes SafeLine Special?
Unlike many traditional WAFs that rely purely on pattern matching or signature rules, SafeLine uses a semantic analysis engine that understands request intent. This drastically reduces false positives while still blocking advanced payloads.
The same engine is used across all editions — including the free version.
Want to Go Deeper?
If you’d like to test more, you can:
- Spin up a local vulnerable app like DVWA or VulnLab and place it behind the SafeLine demo using a proxy.
- Contact the SafeLine team on Discord for testing tips.
Final Thoughts
SafeLine makes it easy to test real-world protection — no install, no hassle. Whether you're a security researcher, devops engineer, or just a curious tinkerer, this public demo is a safe and fast way to assess WAF effectiveness against the OWASP Top 10.
