VPN vs TLS: Are They Solving the Same Problem?
Both protect data in transit, but TLS commonly protects a specific application connection while VPN can protect a broader network tunnel.
TLS
Transport Layer Security protects communications between applications or endpoints, with HTTPS as a familiar example.
VPN
A Virtual Private Network creates an encrypted tunnel that can protect a broader set of network traffic between endpoints or networks.
Certificates
TLS commonly uses digital certificates to help establish server identity and support encrypted sessions.
Remote work
VPN technologies are commonly used to connect remote users or sites securely to private network resources.
The takeaway
TLS commonly protects an application connection. VPN commonly protects a broader tunnel.
