Deploying SafeLine

Introduction

SafeLine is an open-source web application firewall (WAF) that uses semantic analysis and machine learning to protect web applications from attacks. Unlike traditional signature-based WAFs, SafeLine understands the context and meaning of HTTP requests, providing more accurate threat detection with fewer false positives.

Developed by Chaitin Tech, SafeLine offers enterprise-grade protection in an easy-to-deploy package. The semantic analysis engine can detect zero-day attacks and novel attack patterns that would bypass signature-based systems, while the intuitive dashboard makes security management accessible to teams without dedicated security expertise.

Key highlights of SafeLine:

Semantic Analysis: Context-aware attack detection beyond signatures
Machine Learning: Adaptive detection for emerging threats
Low False Positives: Intelligent analysis reduces alert fatigue
SQL Injection Protection: Deep detection of SQLi variants
XSS Prevention: Block cross-site scripting attacks
Bot Protection: Identify and block malicious bots
Rate Limiting: Prevent brute force and DDoS attacks
API Protection: Secure REST and GraphQL endpoints
Real-Time Dashboard: Visual security monitoring
Attack Analytics: Detailed threat intelligence
Easy Integration: Reverse proxy deployment model

This guide walks through deploying SafeLine on Klutch.sh using Docker, configuring protection for your applications, and monitoring security events.

Why Deploy SafeLine on Klutch.sh

Deploying SafeLine on Klutch.sh provides several advantages for web security:

Simplified Deployment: Klutch.sh automatically builds your SafeLine configuration without complex setup.

Persistent Storage: Attach volumes for configuration and security logs. Your rules and analytics survive restarts.

HTTPS by Default: Secure access to the management dashboard with automatic SSL certificates.

Scalable Resources: Allocate CPU and memory based on traffic volume and analysis depth.

GitHub Integration: Store configuration in version control for reproducible deployments.

Always-On Protection: 24/7 availability ensures continuous application security.

Prerequisites

Before deploying SafeLine on Klutch.sh, ensure you have:

A Klutch.sh account
A GitHub account with a repository for your SafeLine configuration
Basic familiarity with Docker and reverse proxy concepts
Web applications to protect
(Optional) A custom domain for SafeLine dashboard

Deploying SafeLine on Klutch.sh

Create Your Repository

Create a new GitHub repository for your SafeLine deployment. Add a Dockerfile:

FROM chaitin/safeline-mgt:latest

ENV MGT_HTTP_PORT=9443
ENV SAFELINE_DIR=/safeline

EXPOSE 9443

HEALTHCHECK --interval=30s --timeout=10s --start-period=60s --retries=3 \
  CMD curl -fsk https://localhost:9443/api/health || exit 1

Push to GitHub

Commit and push your Dockerfile to your GitHub repository.

Create a New Project on Klutch.sh

Navigate to the Klutch.sh dashboard and create a new project.

Create a New App

Within your project, create a new app. Connect your GitHub account and select your repository.
