An extranet is a private computer network that allows authorized external users, such as business partners, suppliers, or customers, to access specific information and services from a company’s internal network. It serves as a secure and controlled extension of a company’s intranet, providing a collaborative platform for sharing data, communication, and conducting business transactions. Unlike the public internet, an extranet requires authentication and authorization to access its resources, ensuring confidentiality and privacy of sensitive information. It enables organizations to streamline their operations, improve communication and collaboration with external stakeholders, and enhance their overall efficiency and productivity.
