ZoogVPN

An established, free-tier-friendly VPN that converts on a clean CPA — affiliates get paid for every qualified action, no waiting on subscription cycles.

ZoogVPN is a long-running VPN provider built around a freemium model: a no-cost tier capped at a handful of locations and limited monthly bandwidth, plus paid plans that unlock its full server fleet across 25+ countries. As marketed, it pairs AES-256 encryption with modern protocols like WireGuard and OpenVPN, a kill switch, P2P-optimised servers, and obfuscation tools (Shadow protocol, ZoogTLS) aimed at users in restrictive regions. It targets cost-conscious privacy seekers, streamers and travellers who want to try before they buy.

For affiliates, ZoogVPN runs worldwide (GEO=WW) on a CPA model paying 3.50 USD per qualified action. CPA (cost per action) means you earn a fixed bounty when a referred user completes the defined conversion event — unlike CPS, which pays a share of a sale, or CPI, which pays per app install. The free tier lowers the barrier to that first action, making CPA-friendly funnels (privacy blogs, streaming/unblocking content, comparison reviews) effective. With no GEO restriction, you can scale across English and non-English markets alike.
