CyberGhost vs Proton VPN
Both market themselves on privacy, but they get there differently. Proton VPN leans on Swiss jurisdiction and fully open-source apps; CyberGhost leans on a Deloitte audit, Romanian jurisdiction, and a much lower long-term price.
Side-by-side
| Factor | CyberGhost | Proton VPN |
|---|---|---|
| Jurisdiction | Romania (no data-retention law) | Switzerland (strong privacy law) |
| Independent audit | Yes — Deloitte (servers & management systems) | Yes — published third-party security audits |
| Open-source apps | ✗ No | ✓ Yes |
| Price (best long-term plan) | €2.19/mo (26-mo plan, billed €56.94 upfront) | ≈ $4.99+/mo (Plus, longer plans) |
| Simultaneous devices | 7 | 10 (Plus) / 1 (Free) |
| Free plan | ✗ No | ✓ Yes — unlimited data, 1 device, no streaming/P2P |
Where CyberGhost wins
CyberGhost is meaningfully cheaper on its best long-term plan and covers more simultaneous devices than Proton's free tier. Its Deloitte audit is a genuine, if less publicly detailed, third-party check on the no-logs claim.
Where Proton VPN has the edge
Proton VPN's apps are fully open-source — auditable by anyone, not just a firm CyberGhost hired — and its free tier is genuinely usable for basic privacy, not just a trial. If open-source verification matters most to you, Proton is the stronger privacy pick.
Choose CyberGhost if price-to-privacy value and device count matter most. Choose Proton VPN if you want open-source apps you (or a security researcher) can inspect yourself, and you're willing to pay more for it.
