ProxyStrike

Also included in Kali Linux is an active proxy known as ProxyStrike. This proxy not only intercepts the request and response, but it also actively finds vulnerabilities. It has modules to find SQL injection and XSS flaws. Similar to other proxies that have been discussed previously, you need to configure the browser to use ProxyStrike as the proxy. It performs automatic crawling of the application in the background, and the results can be exported to both HTML and XML formats.
