Extranets can help businesses improve their customer service, increase their revenue, and save time and resources. The network helps facilitate the flow of information to customers, suppliers and partners. It can be utilized to lets the company's suppliers get point of sales reports at any time, day or night, and can enable you to offer real-time inventory access.

Extranets are based on Open Internet Standards such as HTTP, TCP/IP, FTP, SMTP, HTML, MIME, SSL, etc. Industry Standardization allows products from various companies to interact and communicate enabling Extranet applications to operate in a complex environment utilizing technology from multiple vendors:
web browsers, web servers, secure servers, remote administration tools, directory servers, authentication servers, ecommerce systems, distributed databases and objects, email and fax systems, firewalls, etc.

A primary design concern is security for Extranet traffic as you are making sensitive proprietary information and systems available to outside companies. Care must be taken to ensure that internal corporate systems are adequately protected, and that group members can only access approved resources.


As ecommerce on the World Wide Web continues to grow, security concerns for mission critical systems and data are becoming ever more critical. To safeguard important proprietary systems and information, a Virtual Private Network (VPN) linking Intranets and Extranets securely over the Internet is essential.

A VPN utilizing private encryption keys assures that your valuable resources are secure from unauthorized access. Our complete VPN solutions based on Industry Standard proven technology and Open Architectures guarantee Affordable Quality and a VPN you can rely on.

Doing Business On The Web

A Tiered Approach

 First Tier
The first tier, or client, is the hardware and software with which the end user interacts.

Middle Tier
The middle tier is the hardware and software that resides between the client and the enterprise server resources and data. The software includes a Web server that receives requests from the client and invokes Java servlets to process these requests. The client communicates with the Web server via industry standard protocols such as HTTP and IIOP.

Third Tier
The third tier, or back end, is the hardware and software that provides database and transactional services. These back-end services are accessed through connectors between the middle-tier Web server and the third-tier server.
