No. You are provided with your own dedicated database stored on the Vestigo servers.
Your system is designed such that your users may only see data that is explicitly relevant to them. Within your tracking system an administrator may grant and revoke privileges (view, add, update or delete) to users in each section of the program. Users can be activated or deactivated instantly.
Your tracking system includes a password security model that protects all access points to the application. The security model also controls the data that each user is permitted to view and modify.
