Key Characteristics
Extranet-based VPN is a VPN solution that provides secure access to an organization's extranet, allowing external partners, suppliers, or customers to access specific resources. An extranet is a private network that uses internet technology to securely share part of an organization's information or operations with external parties.
Extranet-based VPNs provide controlled access to specific resources without granting access to the entire internal network. These VPNs typically use strong authentication and authorization mechanisms to ensure that external users can only access resources appropriate to their business relationship with the organization.
