A Virtual Private Network (VPN) is a technology that establishes a secure, encrypted connection over a public or untrusted network, such as the internet. VPNs are designed to protect data in transit, ensuring confidentiality and integrity between endpoints by tunneling network traffic through secure protocols. Core capabilities of VPN solutions include encryption of data packets, user authentication, and masking of IP addresses to obscure user location and activity. VPNs can support remote access for individual users or site-to-site connections between organizational networks. They are commonly deployed to enable secure remote work, protect sensitive communications, and facilitate access to internal resources from external locations. Typical users of VPN solutions include enterprises seeking to secure remote employee connections, managed service providers, and individuals requiring privacy or secure access to restricted resources. VPNs differ from adjacent categories such as Zero Trust Network Access (ZTNA) and Secure Web Gateways (SWG) by focusing primarily on encrypted tunneling and network-level security rather than granular application access or web content filtering.
