| Open-Source | ✅ Apps | ✅ Full protocol |
| 最適な用途 | Personal privacy & streaming | Businesses & IT teams |
1. 使いやすさ
プライベートインターネットアクセス: PIA gives you polished apps for every major platform. Download the app, log in, and click connect. That’s it. The interface shows your connection status, protocol, and speed in one clean window. You can switch servers in seconds from a simple list.
オープンVPN: OpenVPN requires manual setup. You need to install the client, download configuration files, and edit text-based .ovpn files. The Community Edition has no graphical dashboard. Access Server adds a web admin panel, but you still need server management skills.
💡 Test Result: PIA took us 2 minutes to set up and connect. OpenVPN Access Server took over 30 minutes. If you want a VPN that just works, PIA is the clear pick.
2. サーバーネットワーク
プライベートインターネットアクセス: PIA runs 35,000+ servers in 91 countries. It covers all 50 US states. You get streaming-focused servers for Netflix, Disney+, and other platforms. Server switching takes one click.
オープンVPN: OpenVPN has no server network. You host your own server or rent one from a cloud provider. Your server count depends entirely on your budget and setup. Most users run one or two servers at most.
3. Privacy & Security
プライベートインターネットアクセス: PIA uses AES-256 encryption with WireGuard and OpenVPN protocols. Deloitte has audited PIA’s no-logs policy three times. PIA’s apps are open-source. It also publishes quarterly transparency reports.
オープンVPN: OpenVPN uses SSL/TLS encryption with AES-256 support. The protocol itself is open-source and battle-tested since 2001. However, privacy depends on whoever runs the server. There’s no third-party audit of the Access Server product.
4. Speed & Performance
プライベートインターネットアクセス: PIA’s WireGuard protocol delivers the fastest speeds. On nearby servers, speed drops stay around 30-40%. OpenVPN mode is slower, with drops reaching 54%. PIA is fast enough for HD streaming and casual gaming.
オープンVPN: OpenVPN speeds depend entirely on your server hardware and internet connection. On a good cloud server, speeds are solid. But the protocol itself is slower than WireGuard. TCP mode adds more overhead than UDP mode.
💡 Test Result: PIA on WireGuard gave us faster downloads than OpenVPN on the same connection. For raw speed, PIA’s multi-protocol support is a big advantage.
5. Streaming & Content Unblocking
プライベートインターネットアクセス: PIA can unblock Netflix, Disney+, and several other platforms. Results vary by server. Some services work perfectly, while others show occasional buffering. PIA is not the best for streaming, but it works for most popular sites.
オープンVPN: OpenVPN doesn’t unblock streaming services on its own. It’s a protocol, not a service. You’d need to set up your own server in the right country. Streaming platforms will likely block a personal server’s IP quickly.
6. Device Support & Apps
プライベートインターネットアクセス: PIA has dedicated apps for Windows, macOS, Linux, Android, iOS, and browser extensions. It also supports routers. You get unlimited simultaneous connections. Smart DNS is included for devices that can’t run VPN apps.
オープンVPN: OpenVPN Connect is the official client app. It works on Windows, macOS, Linux, Android, and iOS. But you need to configure it yourself with .ovpn files. There’s no one-click app. Access Server adds a web interface for user management.
7. Customization & Control
プライベートインターネットアクセス: PIA lets you switch between WireGuard and OpenVPN. You can choose AES-128 or AES-256 encryption. You also get split tunneling, port selection, and オートメーション rules. But you don’t control the server itself.
オープンVPN: OpenVPN gives you total control. You pick the encryption cipher, key length, authentication method, and routing rules. You can add scripts, plugins, and custom firewall rules. This is the gold standard for VPN customization.
⚠️ Warning: OpenVPN’s deep customization is powerful but complex. Misconfigured settings can create security holes. Only advanced users should modify encryption and routing rules.
8. カスタマーサポート
プライベートインターネットアクセス: PIA offers 24/7 live chat support. There’s also a large knowledge base with guides and FAQs. Email support is available too. Response times have improved a lot in 2026.
オープンVPN: The Community Edition relies on forums and community support. Access Server includes email and chat support for paid users. Documentation is detailed but can be hard to follow for beginners.
9. Pricing & Cost
Let’s compare the pricing plans side by side.
| プラン | プライベートインターネットアクセス | オープンVPN |
|---|---|---|
| 無料 | ❌ (7-day mobile trial) | $0 (2 connections) |
| Cheapest Paid | $2.03/month (2yr plan) | $7/month (Growth) |
