Websecurify
Websecurify is another web application security testing platform designed to provide the combination of automatic and manual vulnerability testing technologies. Some of its key features include easy-to-use user interface, built-in internationalization support, easily extensible with add-ons and plugins, manual testing tools and more.

Nikto2
Nikto is an open source (GPL) web server scanner which performs comprehensive tests against web servers for multiple items, including over 6400 potentially dangerous files/CGIs, checks for outdated versions of over 1200 servers, and version specific problems on over 270 servers. It also checks for server configuration items such as the presence of multiple index files, HTTP server options, and will attempt to identify installed web servers and software.

Sqlmap
Sqlmap is an open source penetration testing tool that automates the process of detecting and exploiting SQL injection flaws and taking over of database servers. It comes with a powerful detection engine, many niche features for the ultimate penetration tester and a broad range of switches.

OWASP WebGoat Project
WebGoat is a deliberately insecure J2EE web application designed to teach web application security lessons. In each lesson, users must demonstrate their understanding of a security issue by exploiting a real vulnerability in the WebGoat application.

BFBTester
BFBTester is great for doing quick, proactive, security checks of binary programs. It performs checks for single and multiple argument command line overflows and environment variable overflows.

Webstretch
Webstretch enables a user to view and alter all aspects of communications with a web site via a proxy. It primarily used for security based penetration testing of websites. It can also be used for debugging during development.

Wapiti
Wapiti is a web application vulnerability scanner that enables you to audit the security of your web applications. The free security auditor performs “black-box” scans, i.e. it does not study the source code of the application but it will scan the webpages of the deployed webapp, looking for scripts and forms where it can inject data. Some of the vulnerabilities can be detected by Wapiti include file handling errors, database injections, XSS injection, LDAP injection, command execution detection as well as CRLF injection.
