With your system you get a control panel like the example below from which you manage your website. The one here shows all of the options available to you. However, you may want a certain member of your staff to be have limited privileges. For example, you may want certain staff to be able to add new links and news items but not change the text on the home page.
The privilege control system allows you to do this and such a member of staff would not see all of the options shown below should you decide to restrict their privileges.
Many Content Managed Systems are not secure. Some have simply one master login and password that enables you change content on the website. This works fine until a disgruntled member (or ex member) of staff decides it would be good to put an obscene photo on your home page!
The Virtual Venture system is secure and the privilege control system sophisticated. What is more, because the system it is maintained for you should a security loophole be discovered it will be fixed for you within the scope of the monthly maintenance charge.
