Dynamic virtual private network definition
A dynamic virtual private network (VPN) is a type of VPN that can recognize added nodes without them first being identified by hardware or a router. Unlike traditional VPNs with static or fixed configurations, dynamic VPNs can dynamically generate connections on demand in response to shifting needs.

How dynamic virtual private networks work
In terms of user functionality, dynamic VPNs work the same as other VPNs — they improve online privacy and security by encrypting online traffic and hiding the user’s IP address. However, dynamic VPNs offer considerably more flexibility when it comes to connectivity.
In a dynamic VPN, connections are established and torn down based on user real-time user requests or changing circumstances. To adapt network alterations and route traffic efficiently, these VPNs often employ dynamic routing protocols like BGP (Border Gateway Protocol) or OSPF (Open Shortest Path First).
Dynamic virtual private network use cases
- Dynamic VPNs allow remote employees to establish secure connections to the corporate network as needed.
- Dynamic VPNs enable secure connectivity for mobile devices.
- In disaster recovery situations, dynamic VPNs can be used to quickly establish temporary connections between recovery sites and primary data centers.
- Dynamic VPNs may be desirable for growing organizations due to their inherent scalability.
