Extranets
A corporate extranet is exactly the same as an intranet in design and structure but unlike its forerunner, it will allow people to securely access it from a remote location. This access could be for business partners, chosen customers or employees wishing to access corporate systems from home.

The benefits of using a corporate extranet cannot be underestimated. More and more companies are keen for employees to work from home and utilising an extranet can cause a welcome extension of business systems into the home environment. One of the critical aspects of using this technology is security, since you will be opening up your internal systems to the outside world, so operating securely is a pre-requisite for using such an application successfully. User authentication, message encryption and firewall are all security aspects which require further consideration.
