Provider-provisioned VPN

A provider-provisioned VPN (PPVPN) is a virtual private network (VPN) implemented by a connectivity service provider or large enterprise on a network they operate on their own, as opposed to a "customer-provisioned VPN" where the VPN is implemented by the customer who acquires the connectivity service on top of the technical specificities of the provider.

When internet service providers implement PPVPNs on their own networks, the security model of typical PPVPN protocols is weaker with respect to tunneling protocols used in customer-provided VPN, especially for confidentiality, because data privacy may not be needed.
