NetFlow is typically used for several key customer applications, including the following:

…

Billing and accounting. NetFlow data provides fine-grained metering (for instance, flow data includes details such as IP addresses, packet and byte counts, time stamps, type of service (ToS), and application ports) for highly flexible and detailed resource utilization accounting. Service providers may use the information for billing based on time of day, bandwidth usage, application usage, quality of service, and so on. Enterprise customers may use the information for departmental charge back or cost allocation for resource utilization.

Dynamic Multipoint VPN (DMVPN) is a Cisco IOS Software-based security solution for building scalable enterprise VPNs that support distributed applications such as voice and video. DMVPN provides scalability for organizations with many remote sites by using a hub-and-spoke topology with dynamic tunnels between spokes. This reduces the number of static tunnels required and simplifies the configuration and management of the VPN. DMVPN also supports dynamic routing protocols, multicast traffic, and quality of service (QoS) features, making it suitable for various network scenarios and requirements12 References := 1: Cisco Dynamic Multipoint VPN: Simple and Secure Branch-to-Branch Communications 2: Implementing and Operating Cisco Security Core Technologies (SCOR) v1.0
