Definition: An extranet is a private network that leverages Internet technologies to securely share part of a business’s information or operations with external parties such as suppliers, vendors, partners, customers, or other businesses. This controlled exposure enhances collaboration and efficiency across various business functions while maintaining stringent security measures to protect sensitive data.

    • A manufacturing company uses an extranet to allow its suppliers to access inventory levels, product quality data, and production schedules, enabling seamless coordination and reducing lead times.

  2. Vendor Management System:

    • A retail chain employs an extranet to manage vendor agreements, automate purchase orders, and streamline communication regarding delivery schedules and product specifications.

  3. Customer Support Platform:

    • An IT service provider implements an extranet to offer clients 24/7 access to service tickets, troubleshooting guides, and system status updates, improving customer satisfaction and service efficiency.
