What is VPN Protocol?

A VPN protocol is the set of rules that determines how a VPN creates the secure, encrypted tunnel between your device and its server. The protocol shapes the balance between speed, security, and reliability. Common examples include WireGuard, OpenVPN, and IKEv2, each with different trade-offs.

The honest bit

Free because Premium pays the bills — never because we sell your data

The usual catch with a free VPN is that it logs and sells your browsing to make money. Zippa doesn’t. Our free tier is funded by people who upgrade to Premium, and we keep a strict no-logs policy — we don’t record the sites you visit, your real IP, or your DNS queries. There’s simply nothing to sell.

FAQ

Frequently asked questions

The questions people actually ask before they install — answered plainly.

  • It depends on your priority. WireGuard is popular for being fast and modern, OpenVPN is trusted and highly configurable, and IKEv2 reconnects quickly on mobile. For everyday browsing, a well-chosen default gives you a good balance without any manual setup.

  • Usually not. Most modern VPNs, including Zippa, select a sensible protocol for you so you can just connect and browse. Manual protocol choice mainly matters for advanced or specialised use cases.

  • It depends who runs it. Plenty of free VPNs pay their bills by logging and selling browsing data — that's the real catch. Zippa is funded by people who upgrade to Premium, not by your data, and we keep a strict no-logs policy, so there's nothing to record or sell in the first place.
