VPN (Virtual Private Network)
A service that encrypts internet traffic and routes it through a secure tunnel, hiding it from anyone on the local network.
VPNs are commonly used to secure remote employee connections back to corporate resources, or to protect traffic on untrusted networks like public Wi-Fi. Traditional corporate VPNs typically grant broad access to the internal network once connected, which is why many organizations are shifting toward ZTNA, which grants narrower, per-application access instead.
