United States market share of commercial VPNs 2019, by vendor

In 2019, with almost 27 percent, Open VPN takes the largest market share of commercial virtual private networks (VPNs) in the United States. A virtual private network itself provides a private connection between the user's device and the endpoint. It does this by utilizing a VPN protocol that masks the user's traffic by encrypting it. VPNs are used both in a private and professional context, for example to either access content that is not accessible in a specific location or isolating an organizations critical information technology (IT) services from the internet.
