Shield Your Web Apps with SafeLine: The Self-Hosted WAF

SafeLine is a robust, self-hosted Web Application Firewall (WAF) built to protect your web applications from a wide range of cyber threats.

A WAF acts as a shield between your web applications and the internet, filtering and monitoring HTTP traffic. It guards against various attacks, including SQL injection, cross-site scripting (XSS), code injection, OS command injection, CRLF injection, LDAP injection, XPath injection, remote code execution (RCE), XXE, server-side request forgery (SSRF), path traversal, backdoor intrusions, brute force attempts, HTTP floods, and bot abuse, among others.

How It Works

By placing a WAF in front of your web application, you create a protective barrier between your app and potential internet threats. Unlike a proxy server, which hides the identity of a client by acting as an intermediary, a WAF functions as a reverse proxy, safeguarding your server by requiring all client requests to pass through the WAF before reaching your server.

The WAF filters, monitors, and blocks any malicious HTTP/S traffic directed at your web application, ensuring no unauthorized data is transmitted out of your app. It does this by following predefined policies that distinguish between harmful and safe traffic. Like a proxy server, a WAF acts as an intermediary, but with the added function of protecting your web application server from potentially dangerous clients.

SafeLine's key features include:

  • Comprehensive Web Attack Defense: Protects against a broad spectrum of web-based threats.
  • Proactive Bot Defense: Prevents bot abuse with advanced detection and mitigation techniques.
  • HTML & JavaScript Encryption: Encrypts your HTML and JS code to bolster security.
  • IP-Based Rate Limiting: Manages traffic by setting limits based on IP addresses.
  • Web Access Control List (ACL): Implements access control policies to secure your web applications.
