OpenVPN uses SSL/TLS to create an encrypted tunnel between your device and the server.

We will explore 9 key features to help you pick the right tool.
| 特徴 | プロトンVPN | オープンVPN |
|---|---|---|
| 開始価格 | $0/month (free plan) | $0 (Community Edition) |
| Ease of Setup | ✅ One-click connect | ❌ Manual server config |
| サーバーネットワーク | ✅ 18,100+ servers | ❌ Self-hosted only |
| ストリーミングサポート | ✅ Netflix, BBC iPlayer | ❌ None built-in |
| No-Logs Audit | ✅ Third-party audited | ❌ Self-managed |
| キルスイッチ | ✅ | ❌ Manual setup |
| Multi-Hop Routing | ✅ Secure Core | ❌ Requires DIY config |
| カスタマイズ | ❌ Limited presets | ✅ Full control |
| 最適な用途 | Everyday users | IT admins and developers |
1. 使いやすさ
プロトンVPN: Download the app, sign in, and tap Quick Connect. That is it. The app picks the fastest server for you. You do not need any technical knowledge. Settings like kill switch and NetShield are one toggle away.
オープンVPN: You need to install server software, edit config files, and set up certificates. The OpenVPN Connect client is simpler. But the server side still needs technical skills. Most users need an IT admin to get started.
2. Privacy and Security
プロトンVPN: Based in Switzerland with strict privacy laws. It has an audited no-logs policy verified by Securitum. All apps are open source. It uses AES-256 encryption with Perfect Forward Secrecy on every connection.
オープンVPN: The protocol itself is very secure. It supports AES-256 and uses SSL/TLS. But your privacy depends on how you set up the server. If you misconfigure it, your data could leak. There is no third-party audit of your setup.
⚠️ Warning: OpenVPN is only as private as your server setup. A bad configuration can expose your real IP address or DNS queries.
3. サーバーネットワーク
プロトンVPN: It runs over 18,100 servers in 129 countries. You can pick any server from the app. Paid users get access to the full network. Free users connect to servers in 5 locations.
オープンVPN: It has no server network. You host your own server or rent one from a cloud provider. This means you get exactly one location unless you set up multiple servers yourself.
4. 速度とパフォーマンス
プロトンVPN: It uses WireGuard by default, which keeps about 88% of your original speed. The VPN Accelerator feature boosts speeds on long-distance connections. OpenVPN protocol is also available but slower.
オープンVPN: Speed depends on your server hardware and network. The protocol supports both TCP and UDP. UDP is faster but less reliable. Overall, OpenVPN is slower than WireGuard in most tests.
5. ストリーミングとトレント
プロトンVPN: It unblocks Netflix, BBC iPlayer, Amazon Prime Video, Disney+, and more. Torrenting works on all paid servers with port forwarding. The free plan does not support streaming or P2P.
オープンVPN: It does not unblock any streaming service by default. You would need to set up your own server in the right country. Even then, streaming platforms often block cloud server IPs.
6. カスタマイズと柔軟性
プロトンVPN: You can switch protocols, enable split tunneling, and create connection profiles. But you cannot change encryption ciphers or add custom scripts. The app gives you preset options only.
オープンVPN: This is where OpenVPN shines. You control every detail. Pick your cipher, key length, authentication method, and port. You can add scripts, plugins, and custom routing rules.
7. デバイスサポート
プロトンVPN: Native apps for Windows, Mac, iOS, Android, Linux, Android TV, and Apple TV. Browser extensions are available too. Up to 10 devices connect at once on one account.
オープンVPN: The OpenVPN Connect client works on Windows, Mac, Linux, Android, and iOS. It also runs on routers and lesser-known systems like Solaris. But mobile apps feel less polished than desktop.
8. カスタマーサポート
プロトンVPN: Paid users get live chat support from 9 AM to midnight CET. Email tickets usually get a reply within 24 hours. The help center has guides and video walkthroughs for common tasks.
オープンVPN: The Community Edition relies on forums and community docs. Access Server users get ticket-based support. There is no live chat for most plans. Setup help can be limited for beginners.
9. Pricing & Cost

| プラン | プロトンVPN | オープンVPN |

オープンVPN: The Growth plan at $7/month is per-connection pricing aimed at businesses. You still need to pay for your own server hosting on top of that. The Community Edition is free but limited to 3 connections.
