What is Extranet ?


A customized service known as an extranet is managed and controlled by a private network. Only partners, vendors, and suppliers have access to this tailored and restricted technology; occasionally, though not always, some particular customers may as well. An extranet is a private network organization that extends its services to users outside of the firm and is actually a portion of the intranet of the individual business. Selling products to customers and conducting business with other companies are occasionally seen as specialized techniques. Extranet technology enables the intranet from one site to another and also provides security to data flow so that business can be conducted with other business partners. Firewall server management is necessary for an extranet service to ensure security and privacy.
