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

FactorCyberGhostProton VPN
JurisdictionRomania (no data-retention law)Switzerland (strong privacy law)
Independent auditYes — 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 devices710 (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.

✓ Bottom line

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.
