AppSense Security Analyzer 1 is a distinguished and tractable tool which gives IT and security managers visibility into some of the most common, but often overlooked, endpoint weaknesses by identifying holes that can be exploited by increasingly sophisticated malware, illegal downloads or user-introduced applications.

No installation is required. Upon launch, AppSense Security Analyzer conducts a comprehensive analysis of a system by attempting to run unauthorized applications and perform various non-disruptive activities on the PC, notebook or server. The degree to which it is able to successfully complete these actions indicates the level of risk faced by that device. In less than 30 seconds, AppSense Security Analyzer creates a report that not only identifies where potential vulnerabilities exist, but also provides guidance on how they can best be addressed.
