Understanding VPN and Split Tunnel

What is a VPN?

A Virtual Private Network (VPN) is a powerful tool designed to provide secure remote access to private networks over public internet infrastructure. By encrypting data and using tunneling protocols such as SSL VPN and IPsec, VPNs create a secure channel, protecting sensitive information from potential cyber threats, especially in Azure environments. This robust security solution is essential for businesses looking to maintain confidentiality and integrity in their communications.

Definition of Split Tunnel

A split tunnel is a specialized VPN configuration that allows traffic to be selectively routed between the secure VPN tunnel and the open internet. This approach enables specific traffic to be directed through the VPN for enhanced security, while other data can access the internet directly, ensuring efficient use of bandwidth and reducing unnecessary load on network resources. This flexibility is crucial for balancing security with performance.
