OysterVPNとは何ですか?
OysterVPN is a VPN service based in Ireland.
Ireland sits outside the 5, 9, and 14 Eyes alliances.
It encrypts your online traffic and routes it through remote servers.
Each OysterVPN subscription covers multiple devices, up to five at once.
Its lifetime access plan is rare in the VPN industry.
But the network is small, and no outside 監査 has checked it.

Runner Up: OysterVPN
One payment can cover you for life. Torrenting works on every server. A kill switch and leak protection come standard.
OysterVPNの価格設定
OysterVPN offers one feature set. You only pick how long you pay for.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 1ヶ月+2ヶ月無料 | 月額5.99ドル | Testing before you commit |
| 生涯アクセス | 月額59.99ドル | People who hate renewals |
| 1年 | 月額29.99ドル | Yearly budget planners |
Pricing verified September 2026.

無料トライアル: No free trial and no free VPN tier.
返金保証: Every plan carries a 30-day guarantee. That makes the service risk free for a month.
📌 注記: OysterVPN only takes major credit cards and PayPal. Cryptocurrency isn’t accepted.
⚠️ Price check: Other sources list the monthly plan at $9.99 with 3 free months. They show the yearly plan at $2.50/month and lifetime access as a one-off $49.99 payment. Confirm the final price before you purchase OysterVPN.
OysterVPNの主な利点
Here are the OysterVPN features that matter most:

- 生涯アクセス: One payment covers the service for life. No yearly renewal surprises.
- Solid Security Basics: AES-256 encryption, a kill switch, and DDoS protection come built in. Leak protection covers IP, DNS, and WebRTC.
- Protocol Choice: Pick between secure VPN protocols like オープンVPN and IKEv2. Switch them in settings.
- Torrent-Friendly: Torrenting is allowed on all OysterVPN’s servers. P2P traffic gets the same protection.
- 広告およびマルウェアブロッカー: Unwanted domains get blocked before they load. That means fewer pop-ups and trackers.
- Intuitive Apps: The OysterVPN apps keep a user friendly interface on desktop and mobile. Beginners can connect with one tap.

機能比較
Now let’s put CyberGhost vs Oyster VPN side by side. We’ll cover nine features, then pricing.
| 特徴 | サイバーゴースト | オイスターVPN |
|---|---|---|
| 開始価格 | 月額2.03ドル | 月額5.99ドル |
| 無料プラン | ❌ | ❌ |
| サーバーネットワーク | 100か国で9,200人以上 | Small (sources vary) |
| 同時デバイス | 7 | 5 |

| Linuxアプリ | ✅ | ❌ |
| 返金保証期間 | 45日間 | 30日間 |
| 最適な用途 | Streaming and wide coverage | Lifetime budget buyers |
1. Streaming & Geo-Unblocking
サイバーゴースト: Its dedicated streaming servers cover 15+ Netflix libraries and BBC iPlayer. Amazon Prime Video, Disney+, Peacock, and Paramount Plus work too. Regional picks like RTVE, DRTV, TV4Play, and C MORE are in the list too. HD video plays without long loading times. That holds on laptops, any mobile device, and streaming devices like Fire TV Sticks.
オイスターVPN: It can unblock Netflix, Max, ESPN+, and BBC iPlayer for geo restricted content. It struggles with Hulu and Disney+. HD streaming can stutter, and 4K on far-off servers isn’t reliable.
⚠️ 警告: If Hulu or Disney+ matter to you, test them during OysterVPN’s refund window. Streaming is CyberGhost’s biggest strength across streaming sites.
2. Speed & Server Network
サイバーゴースト: CyberGhost’s servers span 126 locations. WireGuard has reached speeds up to 760 Mbps in tests. Average speed loss sits near 30%, and distant servers can drop up to 60%. European and US servers beat those in Asia and Africa.
オイスターVPN: Nearby servers give decent download speed and upload speed for browsing. OysterVPN’s speeds drop about 55% on distant servers. Sources disagree on network size. Some list 150+ servers in 17 countries. Others cite 400+ in 35+ countries.
💡 プロのヒント: Pick a nearby server for the best connection speeds on either VPN. Your physical location matters more than any “fastest server” label in a speed test.
3. Encryption & Protocols
サイバーゴースト: CyberGhost uses AES-256 encryption with WireGuard, OpenVPN, and IKEv2. It can also route traffic through a random port. That makes VPN use harder for networks to spot.
オイスターVPN: It also uses AES-256 and offers OpenVPN and IKEv2. Reports conflict on WireGuard. Some sources list it, while others say it’s missing.

⚠️ 警告: Check the protocol menu in the OysterVPN app before you commit. Missing WireGuard would mean slower speeds.

4. No-Logs Policy & Audits
サイバーゴースト: A strict no logs policy means no traffic records, connection logs, or browsing history. Deloitte audited it in 2022 and again in January 2024. Transparency reports and a bug bounty program add more checks.

オイスターVPN: It promises a zero logging policy and says it stores no user data. But no third-party firm has audited it. You’re trusting the company’s word.

⚠️ 警告: Only CyberGhost has an audited no logs policy backing CyberGhost’s privacy claims. Some reviewers still 質問 data sharing with its parent company.
5. Leak Protection & Kill Switch
サイバーゴースト: An automatic kill switch cuts your internet connection if the VPN tunnel drops. DNS leak protection keeps your DNS queries inside the tunnel. Your real IP address stays hidden.

オイスターVPN: The internet kill switch blocks traffic when the VPN connection drops. IP leak protection stops IP leaks, DNS leaks, and WebRTC leaks. That stops accidental data leaks on shaky Wi-Fi.

💡 プロのヒント: Turn the kill switch on in both apps. It’s a crucial feature for torrenting and public Wi-Fi.

6. Ad, Tracker & Malware Blocking
サイバーゴースト: A built-in blocker stops ads, trackers, and malware domains. CyberGhost’s malicious URL filter blocks known risky pages. Windows users can add a security suite with a Security Updater for outdated apps.
オイスターVPN: The built-in ad and malware blocker filters bad domains from your DNS requests. It works quietly in the background. No extra setup is needed.

7. Apps, Devices & Ease of Use
サイバーゴースト: CyberGhost’s apps cover Windows, macOS, iOS, Android, and Linux. Android TV, Apple TV, and Amazon Fire TV are supported too. You get seven simultaneous device connections, counted by device rather than connection.
オイスターVPN: Desktop and mobile apps cover Windows, macOS, iOS, and Android, each with a user friendly layout. You get five simultaneous connections, not unlimited connections. There’s no Linux app and no smart TV or console app.

⚠️ 警告: Some users report bugs in CyberGhost’s Windows app. CyberGhost’s mobile apps and desktop apps get similar complaints. Keep each app updated.
8. Torrenting, Gaming & Split Tunneling
サイバーゴースト: Torrenting and gaming servers sit right in the sidebar. The split tunneling feature works on the Windows and Android apps. Smart Rules can pick a server when a game opens.
オイスターVPN: Torrenting is allowed on all servers, with solid P2P security. Split tunneling works only on Windows and Android. The マック app and iOS app don’t have it.

💡 プロのヒント: Use split tunneling to keep banking apps off the VPN. Everything else stays inside the tunnel.

9. Dedicated IP & DDoS Protection
サイバーゴースト: A dedicated IP costs $5 extra each month. Shared IP addresses on a busy VPN server often trigger CAPTCHAs and banking blocks. A unique IP address only you use avoids that.

オイスターVPN: DDoS protection shields your connection from flood attacks. That helps gamers and live streamers most. It rounds out the advanced security features at no extra cost.

10. 価格設定とコスト
Here are both plan lists side by side.
| プランの種類 | サイバーゴースト | オイスターVPN |
|---|---|---|
| 毎月 | 1 Month: $12.99/month | 1-Month +2 Months free: $5.99/month |
| 中間試験 | 6 Months: $6.99/month | ❌ |
| 長期 | 2 Years + 4 Month: $2.03/month | 1-Year: $29.99/month |
| 一生 | ❌ | Lifetime Access: $59.99/month |
| 返金期間 | 45 days (14 on monthly) | 30日間 |
| Payment | Card, PayPal, Google Pay, Bitcoin | Card, PayPal |
サイバーゴースト: The long plan is the cheapest way to get a big-name VPN. Short plans cost far more per month. The 45 day money back window on longer plans lowers your risk.
オイスターVPN: The lifetime plan is the main draw for buyers who plan to stay. But you get a smaller network and no audit. There’s no 暗号 payment option either.
さまざまなシナリオ

|---|---|---|
| 長期的に見て最低価格 | サイバーゴースト | $2.03/month on the long plan |
| No renewals ever | オイスターVPN | 生涯アクセスオプション |
| Hulu or Disney+ | サイバーゴースト | Streaming servers unblock both |

| Smart TVs or Linux | サイバーゴースト | Apps plus Smart DNS |

💰 あなたの予算
CyberGhost wins if you commit to its long plan. OysterVPN only makes sense if the lifetime deal fits your wallet.
🔌お使いのデバイス
CyberGhost covers seven devices, plus smart TVs through its Smart DNS feature. OysterVPN covers five and skips Linux, consoles, and TVs.
📺 あなたのストリーミング習慣
Heavy streamers should pick CyberGhost for its labeled streaming server tab. OysterVPN handles Netflix but falls short on popular streaming services like Hulu.
🎓 あなたの経験レベル
Both apps are easy for beginners. CyberGhost labels servers by activity, so you never guess which one to use.
🆓 無料トライアルとデモ
Neither VPN has a free tier. Use each refund window as a trial and test your own streaming services.
🛟 サポートオプション
CyberGhost’s customer support offers 24/7 live chat with quick, friendly agents. Email and a knowledge base are there too. OysterVPN has no live chat support or phone line, and email replies can be slow.

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 everyday privacy, streaming, and torrenting. We didn’t test either VPN in restrictive countries like China. OysterVPN reportedly doesn’t work reliably there. Browser extensions, router setups, and gaming consoles weren’t evaluated. Features reflect September 2026 versions and may change.

🏆 優勝者:サイバーゴースト
CyberGhost wins 6 out of 8 categories.
最適な用途: Streamers, multi-device households, and privacy-first users
CyberGhost and OysterVPN aim at different buyers. CyberGhost gives you a big network, audited privacy, and streaming servers that work. Its weak spots are buggy apps and slower distant servers.
OysterVPN is a decent VPN for basic online security and torrenting on a fixed budget. The lifetime plan is its best card. But the small network, missing audit, and thin support hold it back.
For most VPN users, CyberGhost is the safer pick. Choose OysterVPN only if a one-time payment matters more than coverage.
