Web attacks are evolving fast โ from SQL injection and XSS to bot scraping and vulnerability scanners. If you're running a web app or API, it's no longer a matter of if you'll get targeted, but when.
Enter SafeLine WAF โ a high-performance, open source Web Application Firewall you can deploy with a single command. Built for private, self-hosted environments, it combines powerful protection, intelligent detection, and a developer-friendly setup. No cloud lock-in. No license fees. Just raw security, under your control.
๐ What Is SafeLine WAF?
SafeLine WAF is an open source Web Application Firewall developed by Chaitin Tech. Designed for private deployment, it acts as a reverse proxy in front of your web services, filtering and inspecting all HTTP traffic to block attacks before they reach your app.
It protects against:
- SQL Injection (SQLi)
- Cross-Site Scripting (XSS)
- Command Injection
- Path Traversal
- CC Attacks
- Malicious Crawlers
- Automated Vulnerability Scanners (e.g. AWVS, Nessus)
๐ One-Command Installation
Getting started is stupidly easy. Just run:
bash -c "$(curl -fsSLk https://waf.chaitin.com/release/latest/manager.sh)" -- --en
SafeLine handles the installation and configuration for you. No complex setup, no guesswork โ just deploy and start protecting your site.
๐ง Smart Detection with Semantic Analysis
Unlike traditional rule-based firewalls, SafeLine uses semantic analysis algorithms to deeply inspect HTTP payloads. This enables it to:
- Accurately detect and block complex, obfuscated attacks
- Minimize false positives and missed threats
- Stay resilient against evasion techniques
It understands intent, not just patterns โ making it far more reliable than legacy WAFs.
๐ท๏ธ Anti-Crawler & Anti-Scanner Features
SafeLine comes with built-in defenses against scraping and automated scanning tools:
๐ Dynamic Encryption for HTML/JS
Each page load returns a different version of your frontend code โ obfuscated and encrypted โ making it near impossible for crawlers to parse.
๐ค Human Verification
Combines JS challenges, browser fingerprinting, and dynamic tokens to detect and block bots like AWVS, Nessus, and others.
๐ฆ Rate Limiting
Applies per-IP request limits to mitigate brute force and CC attacks.
These protections help you defend against data theft, scraping, content piracy, and automated recon.
๐ Built-In Authentication & SSO Support
SafeLine includes native access control:
- Require username/password to access protected apps
- Supports GitHub, LDAP, OIDC and more
- Integrated SSO (Single Sign-On) for enterprise environments
This makes SafeLine ideal for internal apps, admin panels, or any sensitive service you want to gate.
โ๏ธ Fine-Grained Access Control + High Performance
SafeLine supports advanced traffic control:
- Block or allow traffic based on IP, location, request parameters, and more
- Low latency and high throughput, thanks to an optimized traffic engine
- Scales easily across multiple services or APIs
All with zero sacrifice to performance.
๐ฐ Budget-Friendly, Developer-Ready
Security shouldn't be a luxury. SafeLine is open source, fully self-hosted, and free to use. Itโs designed for developers, startups, and teams who need strong protection without vendor lock-in.
๐งฉ Perfect for These Use Cases:
- Finance: Protect transactions, logins, and account data
- Government / Public Services: Block scanners and secure citizen-facing apps
- E-Commerce: Stop payment hijacking, fraud, and bot-based abuse
- SaaS & Startups: Prevent data leaks and maintain uptime
๐ Monitoring & Dashboard
SafeLine provides a clean web dashboard with:
- Real-time attack logs
- Visual analytics and traffic stats
- Alert notifications for high-risk events
Easy to use, even if you're not a security expert.
