A Virtual Private Network (VPN) creates an encrypted connection between a device and a remote server, protecting data from interception and masking the user's location and internet activity. Organizations use VPNs to allow employees secure access to internal networks when working remotely—connecting through VPN extends workplace network security to remote locations. Consumer VPN services let individuals protect their privacy on public WiFi and access content restricted by geography. Government employees working remotely typically connect through organizational VPNs to access internal systems securely. VPN usage increased dramatically with remote work during COVID-19. VPNs provide important security but can slow connections and may be blocked by some services. Understanding VPNs is increasingly important for digital security awareness.
