Encrypted tunnel creating secure connections over public networks for remote access or site linking.
A Virtual Private Network (VPN) creates encrypted tunnels over public networks, enabling secure remote access to corporate resources or connecting geographically separated offices. Remote access VPN lets individual users connect securely from anywhere; site-to-site VPN connects entire networks. VPN encrypts traffic, protecting against interception. While VPN remains common, Zero Trust Network Access (ZTNA) is increasingly replacing traditional VPN for remote access.
Why It Matters
The DSC Perspective:
VPN enables secure remote access but has limitations—it often grants broad network access rather than specific application access. Consider whether ZTNA might better suit your remote access needs.
