## What it is
SamWaf is a lightweight, open-source web application firewall (WAF) written in Go, designed for small companies, studios, and personal websites. It supports fully private deployment on Linux and Windows 64-bit, encrypts local data, and provides protection features like SQL injection detection, XSS detection, bot detection, CC protection, and custom rules without depending on third-party services.

## Use cases
- protect my personal website from sql injection and xss attacks
- self-host a lightweight waf for a small company website
- block malicious bots and crawlers from my site
- rate-limit and ban IPs doing too many requests (CC protection)
- reverse proxy my web app with ssl and firewall protection
- deploy a private waf without sending data to the cloud
- add ip blacklist/whitelist rules to my website
- detect and block web scanners and rce attempts

## When to choose
- you need a fully private, self-hosted WAF for a small site or studio
- you want a lightweight standalone engine that doesn't require nginx/IIS plugins
- you need local data encryption and privacy (no cloud dependency)
- you run Linux or Windows 64-bit and want easy one-click deployment
- you want built-in OWASP rule sets, bot detection, and CC protection out of the box

## When to avoid
- you need enterprise-scale WAF with advanced ML-based threat detection
- you require cloud-managed WAF with global threat intelligence
- you need deep integration with a specific cloud provider's security stack
- you need a hardware firewall or network-layer (L3/L4) protection appliance
