build extranet, create extranet
We all might know that an intranet helps a company’s private network become easier. However, an extranet is an alternative tool for the company providing the combination of intranet networks. It widens the connection among the organizations. Installing an extranet is concerning about coordination, design, planning, and monitoring several systems to run everything precisely.

Directions
1. Before establishing an extranet, set up goals that you want from an extranet and you, also, need to know the total number of the members who want to access the extranet. Identify how far different level of the users can access and list the system limitation to control data flow and resources.

2. Plan the amount of the information that would suit to the data capacity so that you can identify the precise hardware scale for the system. Check up the data that you want them to be in the data hog for example, mapping, heavy computing, and amount of data moving. Consider whether you want the information to be accessed in a large or a small group.
 
 
Extranet Problems
There is no wonder why many organizations are inspired by the benefits Extranet offered. However, apart from the advantages of using this technology, a concern about potential problems that companies may confront when doing business over Extranet should be discussed. The question is who should be in charge of monitoring Extranet systems?
Leaving all the responsibility to IT department might not be a good idea since problems related to Extranet are not only limited to technical issues, but also cultural concerns. Another thing to consider when talking about potential problems in Extanet use is liability. If other companies are going out of business due to Extranet crash, chances are that the Extranet operator may be liable.

It is important to have all partners maintain the confidentiality. Besides, the host must make sure that there are only intended recipients whom able to see and access the information. Also, the host must confirm that data and server resources are ready for use whenever needed.

The biggest flaw of Extranet system is a matter about security. Anythings that runs over the internet is opened to attack from unauthorized personnel. The more sensitive information such as financial data or new innovation idea that transmitted over Extranet, the more chances that it will draw attention from hackers.

 
 
Although most of us are comfortable with the term "Internet," there is still some confusion when talking about "Intranet" and "Extranet."

Intranet is a term referring to private network used in a company to connect employees and stakeholders together while allowing access to share information and ideas.

In the early age, the Intranet was relatively unrefined. However, advances in technology have allowed for development of modern applications and communications innovations, often referred to as Web 2.0 technologies.
Nowadays the implementation of an Intranet is more and more crucial, especially with the advent of cost-saving applications that are available to big or small companies.

Intranet Software
Office Ability
Office Ability is one of the Intranet solutions that aims to enhance Intranet performance and make leading technology Intranet available to all organizations.  The wide suite of tools and features includes blogs, forums, chat rooms, private messaging and a Facebook-like social media users area.

To provide all the tools of an Intranet to users and stakeholders outside of the company networks is achieved by what was once labeled to be an Extranet system. An Extranet system is set-up on an Internet server and its access is controlled by password encryption.  Extranets (most often still called 'Intranets') are ready to provide a secure and convenient way for organizations to give global access to all users.
 
 
Extranet & Intranet
Extranets are becoming more essential for a technology driven business environment.  An Extranet is able to transform the way a company does business, develop organizational culture, and create opportunities that save cost and increase the bottom line.

Extranet serves as a public Internet or transmission system with limited access to general public and managed by company administrator(s). For example, different security levels can be mapped onto military networks and never connects to the Internet or use virtual private network (VPN) to create a special security protocols for private network that mapped onto a public one.

The idea of developing private networks for sharing information has long been interconnected for decades. One of the unique characters of extranet is that its interconnections are for shared network rather than dedicated physical lines. Generally, there is no distinction between extranet and intranet in terms of VPN. VPN can be understood as a corporate intranet when all sites in the VPN are owned by the same enterprise. However, if the sites in VPN are owned by various enterprises, then the VPN is an extranet.

While a small company can have an intranet, they need to arrange channeled access to geographically distribute VPN to employees. Extranet is also useful for small business providing limited access to intranet systems among suppliers, customers, or other enterprises. It serves as a private section of a website where only users with registration can access through login page. Another thing to consider when talking about extranet is network security. Those that count are including VPN, user authentication, message encryption, digital certificate, firewalls, and server management.
 
 
business extranet
Extranet is simply a company Intranet that has been extended to users outside of the company internal network through the use of Internet servers. Business Extranets use Internet communication technologies to share company databases and open communications to all users, regardless of their location.

The term Extranet is beginning to become blurred in modern times as more company Intranets are being developed with the assumption the these systems need to extend outside of the office building..
