What is Virtual private network?
In short
A virtual private network (VPN) creates an encrypted tunnel over a public network, such as the internet, so remote users can connect securely to an organization's internal network.
Key takeaways
- It protects data in transit from interception but doesn't protect a compromised device at either end.
- Access should still require strong authentication, such as multi-factor authentication.
- Zero trust approaches avoid granting broad network access just because a user is connected.
