VPN (Virtual Private Network)

Stands for Virtual Private Network. Provides security benefits of a private, dedicated, leased-line network without the cost of owning one. Uses cryptography to make data unreadable over the Internet. Commonly used to connect multiple company locations. Weakness of VPN is that it allows access with just a username and password. If a password is leaked, your systems are open. Zero Trust Network Access (ZTNA)is a modern alternative to VPNs.
