ProtonVPN is a free VPN from the makers of ProtonMail with no data limits and no ads. It handles no data limit, no ads, swiss privacy, and secure core, and it's best suited for privacy-conscious users wanting free vpn from a trusted brand. It has been around since 2017, giving it a 9-year head start in building out integrations and refining the product.
The free plan is free with 3 countries — enough for most people to evaluate whether it fits. It's aimed at individual users, so it's fast to set up but may lack team-management features if you scale.
pros
- Includes No Data Limit as a core feature, purpose-built for vpn workflows
- Includes No Ads as a core feature, purpose-built for vpn workflows
- Free with 3 countries — generous enough for most small teams to get real work done
- Includes swiss privacy alongside the core feature set — fewer separate tools needed
cons
- Free plan exists but key features are locked behind the paid upgrade
- Fewer built-in features means you may need additional tools to cover gaps
- Ecosystem of third-party integrations is smaller than the market leaders in vpn
- Limited team/admin features if your organization eventually scales up
