| 最適な用途 | Privacy and activists | Streaming and casual use |
1. Privacy and Logging
プロトンVPN: Based in Switzerland under the world’s strongest privacy laws. The strict no logs policy means no ip logs and no connection logs are stored. Independent auditors have verified the policy, and a transparency report shows the vpn company has complied with very few legal requests.

サイバーゴースト: Headquartered in Romania, which sits outside the 14-Eyes alliance. Deloitte audited cyberghost’s privacy claims in 2022 and again in January 2024. Cyberghost’s servers run on a ram only servers infrastructure, wiping all data on reboot.

2. サーバーネットワークとカバレッジ
プロトンVPN: Around 8,600 proton vpn servers across 112 countries. The server network covers more countries than most vpn companies. Secure core servers route traffic through hardened locations like Switzerland and Iceland before exiting.
サイバーゴースト: A huge server network with over 9,200 vpn servers in 126 locations across 100 countries. CyberGhost beats ProtonVPN on raw server count. Virtual locations cyberghost uses fill in countries where physical servers aren’t practical.
3. ストリーミングとブロック解除
プロトンVPN: Unblocks BBC iPlayer, Netflix, Amazon Prime Video, and Disney+ on Plus and Unlimited plans. No dedicated streaming-optimized servers, but the regular vpn server network handles most streaming services well.
サイバーゴースト: The cyberghost vpn app has a Streaming tab with servers optimized for over 15 Netflix libraries, Hulu, Amazon Prime, Disney Plus, HBO Max, and BBC iPlayer. These streaming optimized servers are regularly tested and updated to keep working.
⚠️ 警告: Streaming sites actively work on blocking access from VPNs. Both services rotate ip addresses to keep up with detection, but no vpn provider can guarantee 100% access at all times.
4. 速度とパフォーマンス
プロトンVPN: The vpn accelerator feature uses advanced networking techniques to improve internet speeds, especially on long-distance vpn connections. Internet traffic stays smooth on nearby servers with WireGuard protocol.
サイバーゴースト: WireGuard speeds reach up to 760 Mbps on close servers in third-party tests. Connection speeds drop significantly on distant servers, with some tests showing up to 60% speed loss in Asia and Africa.
5. セキュリティ機能
プロトンVPN: AES-256 encryption with Perfect Forward Secrecy. Comes with a kill switch, dns leak protection, NetShield ad-blocker, and the Stealth protocol that disguises vpn traffic as regular internet traffic. Multiple dns leak test runs have passed without issue.

サイバーゴースト: Industry-standard AES 256-bit encryption with an automatic kill switch. Cyberghost’s malicious url filter and content blocker stop ads, trackers, and known malware domains. The security suite includes a security updater for outdated software on your mobile device.
6. デバイスのサポートとアプリ
プロトンVPN: Proton apps cover Windows, MacOS, iOS, アンドロイド, Linux, Android TV, and Apple TV. Up to 10 simultaneous device connections. Every linux user gets a full graphical linux app, not just a command-line tool.
サイバーゴースト: Desktop and mobile apps for Windows, macOS, Android, iOS, and Linux. Cyberghost’s mobile apps and cyberghost’s windows app share a similar interface. Up to seven simultaneous device connections on one subscription. Smart DNS works on Amazon Fire TV and other smart tv platforms.
7. Special Features
プロトンVPN: Tor over VPN sends your encrypted vpn tunnel through the tor network for extra anonymity. Port forwarding helps with P2P seeding speeds. Split tunneling lets you pick which apps use the vpn tunnel and which use your normal internet connection.
サイバーゴースト: Smart Rules automate connections based on triggers like Wi-Fi networks or apps. A dedicated ip option for users who need a stable address. The smart dns feature lets you stream on devices that can’t run vpn apps directly.
8. カスタマーサポート
プロトンVPN: Customer support is ticket-based with knowledge base articles on the proton vpn’s website. Response times typically run a few hours rather than a few seconds. No 24/7 live chat support is available.
サイバーゴースト: Offers 24/7 live chat support, email support, and a web knowledge base. Live chat connects in a few seconds and the agents are reported as helpful, though some knowledge base articles can be hard to follow.
9. 価格設定とコスト
料金プランを並べて比較してみましょう。
| プラン | プロトンVPN | サイバーゴースト |
|---|---|---|
| 無料 | 月額0ドル(永久) | ❌ (trial only) |
| 毎月 | 月額9.99ドル(プラス) | 月額12.99ドル |
| Mid-Length | $3.99/month (annual Plus) | 月額6.99ドル(6ヶ月間) |
| 長期 | 月額2.99ドル(2年契約以上) | 月額2.03ドル(2年4ヶ月分) |
| Premium Tier | $7.99/month (Unlimited bundle) | +$5/month for dedicated IP |
プロトンVPN: The free tier alone makes ProtonVPN stand out — most other vpn providers either charge from day one or hide the free version behind ads. Plus pricing is competitive on the 2-year plan, and Unlimited adds Proton Mail, Drive, and Calendar to the bundle.
サイバーゴースト: The 2-year plan is one of the cheapest in the vpn industry at $2.03/month. The 45 day money back guarantee gives plenty of time to test. But there’s no free version, and the monthly plan is pricier than ProtonVPN’s monthly option.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| Tight budget, no privacy needs | サイバーゴースト | $2.03/month is cheaper long-term |
| A real free vpn | プロトンVPN | Only one with no-cost permanent plan |
| Heavy streaming on smart tvs | サイバーゴースト | Streaming-tuned servers and Smart DNS |
| Strong privacy and journalism | プロトンVPN | Secure Core and Swiss jurisdiction |
| P2Pファイル共有 | プロトンVPN | Port forwarding and dedicated P2P servers |

| 複数のデバイスを同時に | プロトンVPN | 10 device connections vs 7 |
💰 あなたの予算
CyberGhost wins on the longest plan at $2.03/month. ProtonVPN wins if you want a free vpn without paying anything.

If you’re a journalist, activist, or just want maximum privacy, ProtonVPN is the safer pick. Secure core architecture and the Swiss jurisdiction are hard to match.

What Our Review Didn’t Cover
This comparison focused on individual users and small households. We didn’t test enterprise team plans or evaluate how either vpn provider performs across hundreds of users. Our observations come from published specs, audit reports, and short-term hands-on use of the proton vpn app and cyberghost app, not from months of daily-use data. If you need a vpn service for an entire company or a specialized setup like running your own endpoint server, your priorities may differ from what we’ve covered.
