## 👋 INTRODUCTION

SafeLine is a self-hosted **`WAF(Web Application Firewall)`** to protect your web apps from attacks and exploits.

A web application firewall helps protect web apps by filtering and monitoring HTTP traffic between a web application and the Internet. It typically protects web apps from attacks such as `SQL injection`, `XSS`, `code injection`, `os command injection`, `CRLF injection`, `ldap injection`, `xpath injection`, `RCE`, `XXE`, `SSRF`, `path traversal`, `backdoor`, `bruteforce`, `http-flood`, `bot abused`, among others.

#### 💡 How It Works

By deploying a WAF in front of a web application, a shield is placed between the web application and the Internet. While a proxy server protects a client machine’s identity by using an intermediary, a WAF is a type of reverse-proxy, protecting the server from exposure by having clients pass through the WAF before reaching the server.

A WAF protects your web apps by filtering, monitoring, and blocking any malicious HTTP/S traffic traveling to the web application, and prevents any unauthorized data from leaving the app. It does this by adhering to a set of policies that help determine what traffic is malicious and what traffic is safe. Just as a proxy server acts as an intermediary to protect the identity of a client, a WAF operates in similar fashion but acting as an reverse proxy intermediary that protects the web app server from a potentially malicious client.

its core capabilities include:

- Defenses for web attacks
- Proactive bot abused defense
- HTML & JS code encryption
- IP-based rate limiting
- Web Access Control List
