Open Source Python Web Application Firewalls (WAF)

CacheGuard Gateway is a simple internet security solution for startups, small businesses and SMEs that need strong protection without complexity. A free, open-source Unified Threat Management (UTM) platform for quick deployment and easy management. Download CacheGuard-OS and install on bare-metal or a virtual machine. In minutes, you get a complete security gateway protecting your network at no cost. Includes firewall, web antivirus, VPN, URL filtering, and SSL-inspecting web proxy in one UTM stack. A built-in Web Application Firewall (WAF) works with reverse proxy, load balancer and SSL offloader to block malicious requests and low-reputation IP traffic. Quality of Service (QoS) prioritises critical traffic, balances multiple WAN links and caches web content to optimise performance.

The Web Application Firewall Fingerprinting Tool. Sends a normal HTTP request and analyses the response; this identifies a number of WAF solutions. If that is not successful, it sends a number of (potentially malicious) HTTP requests and uses simple logic to deduce which WAF it is. If that is also not successful, it analyses the responses previously returned and uses another simple algorithm to guess if a WAF or security solution is actively responding to our attacks. For further details, check out the source code on our main repository.

WhatWaf is an advanced firewall detection tool who's goal is to give you the idea of "There's a WAF?". WhatWaf works by detecting a firewall on a web application and attempting to detect a bypass (or two) for said firewall, on the specified target.

SuStorID is an advanced Intrusion Detection System (IDS) for web services, based on machine learning. Its name comes from the term “Su Stori”, which in Sardinian language means “The Falcon”. It’s version is experimental, but demonstrates a number of interesting features, that can be readily exploited to detect and act against web attacks. SuStorID can be coupled with modsecurity, the well known web application firewall, to gather training data and provide for real-time counteractions. So, SuStorID is a host-based Intrusion Detection System, and by means of modsecurity can access internal web server’s data (i.e. http request/response fields) exactly as Apache does.
