VPN

A VPN (Virtual Private Network) creates an encrypted tunnel between a user's device and a remote network, protecting data from interception and masking the user's IP address. VPN technology is widely used for secure remote access to corporate networks, protecting privacy on public Wi-Fi, and bypassing geographic content restrictions. This index documents VPN providers, protocols, and APIs relevant to the VPN technology landscape including NordVPN, OpenVPN, WireGuard, Tailscale, and cloud provider VPN services.

VPN publishes 3 APIs on the APIs.io network: Catalog API, Servers API, and Stats API. Tagged areas include Encryption, Networking, Privacy, Security, and VPN.

The VPN catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

VPN’s developer surface includes developer portal and 10 more developer resources.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/vpn: open an issue to ask a question, or submit a pull request to add artifacts.
