How does Cisco VPN Concentrator work?
VPN Concentrators use tunnelling protocols to create and manage VPN tunnels. It encapsulates the outgoing network data into encrypted packets and then transmits the data through the VPN tunnel. It receives incoming data, de-encapsulating and decrypting the data.
What is Cisco VPN Concentrator?

What is ipsec concentrator?
In a hub-and-spoke network, policy-based VPN connections to a number of remote peers radiate from a single, central FortiGate unit, or “hub”. The hub functions as a concentrator on the network, managing all VPN connections between the peers, or “spokes”.
Is a VPN Concentrator a router?

What is IPsec and how it works?
IPsec is a group of protocols that are used together to set up encrypted connections between devices. It helps keep data sent over public networks secure. IPsec is often used to set up VPNs, and it works by encrypting IP packets, along with authenticating the source where the packets come from.
Does VPN concentrator aggregate hundreds or thousands of VPN connections?
