First, you get a detailed look at where your network might be vulnerable to an outside attack. Our experience shows that the vast majority of items can be fixed easily and quickly but only if the system administrator knows about the vulnerability. The DSEA agent reduces hours and hours of system admin time down to a single program that can be run and give a detailed report of what needs to be fixed and the relative severity.
Secondly, you gain the confidence of your own customers. Many larger companies are now requiring their vendors and suppliers to comply with a specific set of standards in order to do business with them. The government has also weighed in on this and established numerous compliance standards, such as HIPAA, PCI, SOX, etc. that must be followed in order to avoid stiff fines and penalties.
