AppSentry

AppSentry is a new generation of security scanner and vulnerability assessment tool. Unlike other security scanners, AppSentry knows the application it is validating – its technology and data model. The security audits and checks are written specifically for the application being tested. Hackers and mischievous employees often exploit security issues at different layers of the technology stack, thus only a complete and comprehensive security validation will uncover all risks in a multi-tiered environment

The advantage of AppSentry is you don't need separate tools for the operating system, web server, database, and application. AppSentry is a single tool that can validate and audit the security of the entire application technology stack from operating system to application layer.
