What is a VPN concentrator typically integrated with?

1. A modem

2. A firewall

3. A router

4. A switch

The correct answer is: A firewall

A VPN concentrator is primarily designed to create, manage, and secure connections to a VPN, which is essential for establishing secure communication over the internet. The integration with a firewall is particularly important because both devices contribute to the overall security of the network. The VPN concentrator provides encrypted tunnels for users to access the network securely, while a firewall monitors and controls incoming and outgoing network traffic based on predetermined security rules. Together, they form a crucial combination where the VPN concentrator handles secure remote access and the firewall acts as a barrier that protects the network from unauthorized access and potential threats. This synergy enhances the security posture of the organization, allowing remote users to establish secure connections while ensuring that these connections are tightly monitored and controlled by the firewall. Thus, the integration of a VPN concentrator with a firewall offers robust security measures to protect sensitive data and maintain network integrity.
