⚡ 簡単な評価:
- 価格: CyberGhost starts at $2.03/month on its long plan. OpenVPN has a $0 plan, and Growth costs $7/month.
- 最適な用途: CyberGhost for streaming and everyday privacy. OpenVPN for remote access and self-hosted 仕事 ネットワーク。
- 主な違い： CyberGhost is a ready-to-use VPN service. OpenVPN is a protocol and server software you set up yourself.
- 私たちのおすすめ： CyberGhost for most people. You get servers, apps, and streaming access without touching a config file.
CyberGhost vs OpenVPN is not a fair fight on paper.
One is a full VPN service. The other is the engine many VPNs run on.
CyberGhost VPN gives you apps, a huge server network, and streaming servers.
OpenVPN gives you raw control over your own virtual private network.
So the real question is simple. Do you want to use a VPN or build one?

CyberGhostとは何ですか？
CyberGhost is a consumer VPN service based in Romania.
It hides your real IP address and encrypts your internet traffic.
It lists over 9,200 servers in 126 locations across 100 countries.
That server network is built around streaming, torrenting, and gaming.
You tap one button, and you’re connected in a few seconds.
The desktop and mobile apps look nearly identical on every device.
Here’s a quick video walkthrough of the service.
🏆 優勝：サイバーゴースト
Streaming servers for Netflix, BBC iPlayer, and Disney+. Audited no-logs policy. Seven devices on one account.
サイバーゴーストの価格
CyberGhost has three plans. The longer you commit, the less you pay each month.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 1ヶ月 | 月額12.99ドル | Short trips or a quick test |
| 6ヶ月 | 月額6.99ドル | Seasonal streaming or 旅行 |
| 2年4ヶ月 | 月額2.03ドル | Long-term everyday privacy |
Pricing verified September 2026.
無料トライアル: CyberGhost is not free. The refund window acts as your trial.
返金保証: Longer plans get a 45 day money back guarantee. That’s longer than most VPN providers offer. The one-month plan gets 14 days.
📌 注記： The six-month plan bills $41.94 upfront. The long plan bills about $57 for the first 28 months, then renews yearly. You can pay with a credit card, PayPal, Google Pay, or Bitcoin. A dedicated IP costs an extra $5 billed monthly.
⚠️ Price check: Some review sites say the two-year plan adds two free months. The current offer shows four. CyberGhost VPN deals change often, so confirm the extra months at checkout.
CyberGhostの主なメリット
Here’s what makes CyberGhost worth a look:
- 監査済みノーログポリシー: CyberGhost keeps no connection logs or browsing history. Deloitte checked CyberGhost’s privacy claims in 2022 and January 2024.
- RAM-Only and NoSpy Servers: RAM only servers wipe データ on every reboot. NoSpy servers are owned and run by CyberGhost itself.
- Outside 14-Eyes: Romania sits outside the 14-Eyes alliance. CyberGhost also publishes transparency reports and runs a bug bounty program.
- Seven Devices: One plan covers up to seven devices. The limit counts devices, not open connections.
- スマートルール： You can automatically connect when you open certain apps. Wi-Fi protection kicks in on unsecured networks.
- 24時間年中無休のライブチャット： Chat agents are quick and friendly. Email support is there if you prefer it.

OpenVPN とは何ですか?
OpenVPN is an open source VPN protocol first released in 2001.
It builds a secure tunnel for data traffic between an OpenVPN client and server.
OpenVPN is one tunneling protocol, not a finished consumer app with servers.
The OpenVPN company, once called OpenVPN Technologies, builds business products on the OpenVPN software.
Many VPN providers, including CyberGhost, use it inside their own apps.
This video shows how OpenVPN works, from server to client software.
オープンVPN
Run your own VPN server with open code. Great for remote teams and private networks.
OpenVPNの価格設定
OpenVPN’s business products come in three tiers. The OpenVPN Community Edition stays free.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 無料 | $0 | Home labs and tiny teams |
| 成長 | 月額7ドル | 中小企業 adding users |
| 企業 | カスタム | Large firms with complex networks |
Pricing verified September 2026.
無料トライアル: You don’t need one. The Free plan lets you test with a few connections.
返金保証: OpenVPN doesn’t advertise a fixed refund window. Paid plans can be cancelled anytime.
📌 注記： The Growth price is charged per connection, so more VPN connections cost more. Self-hosting also means paying for your own server.
⚠️ 警告： OpenVPN free is not a free VPN service. You get no servers in other countries. You host everything yourself.
OpenVPNの主な利点
Here’s why IT teams still pick OpenVPN in 2026:
- オープンコード： Anyone can inspect the code, and a global community ships fixes fast. It beats most VPN protocols, including old PPTP.
- Firewall-Friendly: OpenVPN gets past firewalls and NAT gateways well. It works on networks that block other VPN protocols.
- 完全な前方秘匿性： One stolen key doesn’t unlock past sessions. Your old data stays safe.
- Runs Almost Anywhere: It supports all major operating systems. It even runs on Tomato routers and Solaris.
- Scales Up: It handles one remote worker or full site-to-site links. It supports IPv4 and IPv6 traffic.
- Extensible: Third-party apps, scripts, and plugins can add features. Creating VPN tunnels starts with plain-text .ovpn config files.

機能比較
These two tools solve the same problem from opposite ends. Below, we compare nine features plus pricing.
| 特徴 | サイバーゴースト | オープンVPN |
|---|---|---|
| 開始価格 | 月額2.03ドル | $0 (Growth $7/month) |
| 無料プラン | ❌ | ✅ |
| Ready-Made Server Network | ✅ | ❌ |
| ストリーミングサーバー | ✅ | ❌ |
| Self-Hosted VPN Server | ❌ | ✅ |
| サイト間ネットワーク | ❌ | ✅ |
| オープンソースコード | ❌ | ✅ |
| TCP & UDP Support | ✅ | ✅ |
| 最適な用途 | Streaming and personal privacy | Business networks and リモートアクセス |
1. Streaming and Live Sports
サイバーゴースト： Streaming is its biggest strength. CyberGhost’s apps include a sidebar Streaming tab. It lists servers for Netflix, Hulu, HBO Max, Amazon Prime Video, and BBC iPlayer. It also covers Disney Plus, Paramount Plus, Peacock, RTVE, Now TV, DRTV, TV4Play, and C More.
Live sports fans get their own set of servers too. CyberGhost says it tests these servers regularly, so HD streams load without long buffering.
オープンVPN: It has no servers for streaming services at all. If you self-host, your IP address comes from your own server. Streaming sites will only see that one location.
⚠️ 警告： Want to unblock streaming platforms? OpenVPN alone won’t do it. You need a VPN service with servers abroad.
2. Remote Access and Site-to-Site Links
サイバーゴースト： It isn’t built for company networks. You can’t link two offices or reach a private file server. A dedicated IP helps a little, since some work systems allow only known addresses.
オープンVPN: This is its home turf. Companies use it for remote access to internal networks. It scales from one laptop to site-to-site VPN tunnels between private networks.
Site-to-site setups join two offices into one private network. Staff share files as if they sat in the same room.
3. セキュリティと暗号化
サイバーゴースト： Its core security features are AES 256-bit encryption and an automatic kill switch. If the VPN connection drops, the kill switch cuts your internet connection. That stops your real location from leaking.
オープンVPN: The OpenVPN protocol uses Secure Sockets Layer/Transport Layer Security to build the VPN tunnel. The OpenSSL library supplies encryption algorithms like AES and Blowfish, and lets you tune encryption protocols. A hash message authentication code (HMAC) checks every packet, and public key infrastructure manages certificates.
💡 プロのヒント: OpenVPN is only as strong as your settings. Weak encryption keys leave gaps. Pick AES-256 and turn on the HMAC firewall, also called TLS auth.
4. IP Masking and Dedicated IP
サイバーゴースト： Every connection swaps your IP for one from CyberGhost’s servers. You can pick from virtual locations in 100 countries. Websites only see the VPN server, not you.
Shared IP addresses can trigger captchas and bank alerts. That’s where a private address helps.
オープンVPN: Your traffic exits wherever your OpenVPN server lives. If that’s a cloud server, you get its IP. It hides your address from sites, but only in one place at a time.
5. DNS Protection and Content Filtering
サイバーゴースト： It routes DNS queries through its own servers to stop DNS leaks. The built-in content blocker stops ads, trackers, and malware domains.
CyberGhost’s malicious URL filter works alongside that blocker. Here’s how it looks inside the app.
オープンVPN: The free protocol doesn’t filter content. CloudConnexa, its cloud product, adds DNS security and content filtering for business teams.
6. アプリとデバイスのサポート
サイバーゴースト： CyberGhost’s Windows app sits beside a Mac app, iOS app, Android app, and Linux support. CyberGhost’s mobile apps and desktop apps share one clean layout. It also runs on Apple TV, Android TV, Amazon Fire TV, and some smart TVs. For a smart TV without VPN support, the smart DNS feature fills the gap.
オープンVPN: The official OpenVPN Connect client runs on Windows, macOS, Linux, Android, and iOS. Windows users can also try the OpenVPN GUI. The client software feels less friendly on mobile devices than on desktop.
7. Speed, Gaming, and Protocols
サイバーゴースト： Connection speeds drop about 30% on average. Nearby CyberGhost servers are fastest, and WireGuard has hit up to 760 Mbps. Distant servers can lose up to 60%, and Asia or Africa often lag behind Europe and the US.
オープンVPN: It’s slower than newer tunneling protocols like WireGuard. You pick the trade-off yourself. OpenVPN UDP (User Datagram Protocol) is faster but doesn’t guarantee delivery. OpenVPN TCP (Transmission Control Protocol) is slower but keeps every packet in order.
💡 プロのヒント: Choose the UDP protocol for streaming and ゲーム. Switch to the transmission control protocol when a strict network keeps dropping you.
8. Business Cloud and SaaS Protection
サイバーゴースト： It protects one person’s online traffic, not a company. There’s no admin panel for teams. It also sells a separate security suite with antivirus.
オープンVPN: OpenVPN Access Server is a self-hosted VPN server with a web dashboard for VPN clients. CloudConnexa runs OpenVPN connections as a hosted service. Both can lock down access to cloud apps.
SaaS protection goes a step further. It keeps sensitive data private from your internet service provider.
9. Setup and Customization
サイバーゴースト： The CyberGhost app sets up in minutes. VPN users can switch to the open source OpenVPN protocol in settings. CyberGhost’s client also offers a random port option and a security updater. Split tunneling works on Windows and Android.
オープンVPN: Manual configuration can be complex. You edit .ovpn 文章 files and manage encryption ciphers and key lengths. The payoff is a custom security protocol that fits your exact needs, even for IoT gear. There’s no one-tap VPN app here.
10. 価格設定とコスト
Here are both price lists side by side.
| プランレベル | サイバーゴースト | オープンVPN |
|---|---|---|
| 無料 | ❌ | 無料：0ドル |
| Short Term | 1 Month: $12.99/month | Growth: $7/month |
| Mid Term | 6 Months: $6.99/month | — |
| Long Term / Large Teams | 2 Years + 4 Month: $2.03/month | エンタープライズ：カスタム |
サイバーゴースト： The long plan gives you servers, apps, and streaming access for a low monthly price. The monthly plan is poor value unless you need a week or two.
オープンVPN: The software can cost nothing. But you pay in time, and often in server fees too.

私たちのレビューで取り上げられなかったこと
This comparison focused on individuals and small teams. We didn’t audit OpenVPN Enterprise pricing or large Access Server rollouts. We also didn’t check every regional streaming library CyberGhost claims. We didn’t examine data sharing with parent company Kape Technologies, which some critics question. Our full CyberGhost review covers that and more. Details reflect September 2026 versions.

最適な用途: Streaming, public Wi-Fi safety, beginners
💡 Why CyberGhost ranks first: Both tools earn a 4.3 rating from us. We broke the tie by audience fit. Most readers want a VPN they can use today, not one they must build.
CyberGhost is a finished product. You get global servers, clear apps, and streaming access out of the box.
OpenVPN is a toolkit that has powered much of the VPN industry since 2001. It regularly lands on lists of the safest VPN protocols. Most experts call OpenVPN safe when it’s configured well.
Here’s the nice part. You don’t have to pick between virtual private networks and protocols. CyberGhost is an OpenVPN compatible service, so you get both. Read our CyberGhost VPN review for deeper speed notes.
