機能比較
Ready for a closer look at Norton VPN vs OysterVPN? We’ll walk through ten key areas, from encryption to cost.
| 特徴 | ノートンVPN | オイスターVPN |
|---|---|---|
| 開始価格 | 月額3.33ドル | 月額5.99ドル |
| 無料プラン | ❌ | ❌ |
| キルスイッチ | ✅(iOSでは利用できません) | ✅ |
| スプリットトンネリング | ✅ Windows & Android | ✅ Windows & Android |

| 最大デバイス数 | 10 | 5 |
| 返金保証期間 | 60日間(年間) | 30日間 |
| 最適な用途 | オールインワンセキュリティ | 格安トレント |
1. Encryption & VPN Protocols
ノートンVPN: Norton uses AES-256 encryption with WireGuard, OpenVPN, and its own Mimic protocol. It explains how its VPN works in five steps: initiation, encryption, tunneling, IP masking, and the return path. For advanced features, Double VPN routes traffic through two servers.

オイスターVPN: OysterVPN also uses AES-256 and lists OpenVPN and IKEv2 among its secure VPN protocols. Sources disagree on WireGuard. One says it’s supported, and another says it isn’t.

⚠️ 警告: If WireGuard matters to you, check OysterVPN’s protocol menu inside the app during your refund window.
2. Logging Policy & Jurisdiction
ノートンVPN: Norton claims a strict no logs policy. Still, it keeps some log information, like email addresses, timestamps, and usage data for debugging. Details sit in the NortonLifeLock Global Privacy Statement, and the US base puts it inside the 5/9/14 Eyes.

オイスターVPN: OysterVPN promises a zero logging policy and says it stores no user data. Its Irish base sits outside the Eyes Alliances. The catch is that it lacks an audited no logs policy, since no third-party audit has happened.

3. キルスイッチ
ノートンVPN: Norton’s kill switch stops traffic if the VPN connection fails. It’s there on desktop and Android. The iOS app lacks it.
https://youtu.be/vB3jd5KiBn8?si=u6TciXhkyYo1Kxxq
オイスターVPN: OysterVPN’s internet kill switch blocks traffic the moment your VPN connection drops. That’s a crucial feature on public Wi-Fi. It helps prevent accidental data leaks.

4. スプリットトンネリング
ノートンVPN: Split tunneling lets you pick which apps skip the VPN tunnel. Norton offers it on its Windows app and on Android smartphones only.

オイスターVPN: OysterVPN’s split tunneling feature has the same limits. It works on the Windows app and Android app only. Mac and iOS users go without.

5. Leak & Network Protection
ノートンVPN: Norton provides DNS and WebRTC leak protection. But it doesn’t mask IPv6 addresses, which can expose you. Compromised Network Detection and Dark Web Monitoring add identity protection.

オイスターVPN: OysterVPN’s IP leak protection covers IP, DNS, and WebRTC leaks. Its DNS leak protection keeps your physical location hidden from websites. DDoS protection is also among its advanced security features.

💡 プロのヒント: Using IPv6 at home? Disable it on your device before connecting to Norton.

6. 広告とトラッカーのブロック
ノートンVPN: Norton’s ad tracker works across every platform. It blocks ads and trackers during your browsing activities. Norton 360 can add antivirus protection on top.
オイスターVPN: OysterVPN has a built-in ad and malware blocker. It works in the desktop app and on mobile. No extra plugin needed.

7. Streaming & Torrenting
ノートンVPN: Norton’s geo-unblocking works with US and Australian Netflix, Prime Video, and BBC iPlayer. It fails with Netflix UK, Canada, and 日本. Disney Plus doesn’t work either.

オイスターVPN: OysterVPN can reach geo restricted content on Netflix, Max, ESPN+, and BBC iPlayer. It struggles with Hulu, Disney+, and HD streaming. Torrenting is allowed on all servers, so it’s the stronger P2P pick.

⚠️ 警告: Our OysterVPN review mentions dedicated streaming servers, but other sources don’t confirm them. Popular streaming services change blocks often, so test inside your refund window.
8. Server Network & Speed
ノートンVPN: Norton Secure VPN’s servers number around 1,500. Server locations span 28 or 29 countries, fewer than other VPNs. Unlike many VPNs, you can pick a country but not a city.
Published speed tests show connection speeds drop 40% to 55% on average, depending on location. Norton Secure VPN’s performance falls harder far away, with a 73% drop on a Japan server. On its best sessions, Norton’s speeds hit a median of 950Mbps+. It also can’t bypass firewalls in China or Iran.
オイスターVPN: OysterVPN’s servers total 400+ in 35+ countries, though one source lists only 150+ in 17. OysterVPN’s speeds are decent on nearby servers but drop around 55% on distant servers. That’s fine for daily browsing, not 4K, and it isn’t reliable in China.

💡 プロのヒント: Run a speed test on a nearby server first. Compare download speed and upload speed with your normal internet.
9. Apps, Devices & Support
ノートンVPN: Norton Secure VPN’s apps cover Windows, Mac, Android, and iOS. Plans protect one, five, or ten devices. Desktop users download from their Norton account, mobile users use the app stores, and quick-connect finds the fastest server.
After installing, you sign in with your Norton account to activate it. A support library covers setup and troubleshooting if something breaks.
オイスターVPN: OysterVPN apps work across multiple devices, with five connections per account. That’s not unlimited connections. There’s no Linux, smart TV, or console app for streaming devices.
Customer support is thin. There’s no phone line, email replies are slow, and sources disagree on chat support.

10. 価格設定とコスト
Here’s the full plan lineup side by side.
| ティア | ノートンVPN | オイスターVPN |
|---|---|---|
| エントリ | 標準プラン:月額3.33ドル | 1-Month +2 Months free: $5.99/month |
| 真ん中 | デラックス:月額4.17ドル | 1-Year: $29.99/month |
| トップ | セレクトプラス:月額8.33ドル | Lifetime Access: $59.99/month |
| 返金期間 | 60 days annual / 14 days monthly | 30 days, all plans |
| Payment | Credit card, PayPal | Credit card, PayPal |
ノートンVPN: Norton has the cheaper entry point on our CSV figures. Watch renewal rates on annual subscriptions, since promo prices rise later. The Norton 360 bundle is a good deal if you need antivirus too.
オイスターVPN: OysterVPN offers its best value through lifetime access. Other sources list it as a one-off $49.99 fee. If you’ll use a VPN for years, that beats most VPNs.

🔌お使いのデバイス
Norton covers up to ten devices, while OysterVPN caps at five. Linux users should skip OysterVPN.
🔒 あなたのプライバシーのニーズ

🎓 あなたの経験レベル
Both have intuitive apps that beginners can handle. Norton’s support library gives new users more help.
🆓 無料トライアルとデモ
Neither offers a free plan. Norton’s 60-day window on annual plans gives you twice OysterVPN’s testing time.
🛟 サポートオプション
Norton offers a searchable help library. Our writer found OysterVPN’s email replies slow, which matches other user reports.

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 individual users on Windows, Mac, Android, and iOS. We didn’t review the Norton Ultra VPN tier separately or test either brand’s browser add-ons. We also skipped router setups and didn’t check mobile bundles for limited data caps. Prices and server counts reflect September 2026 sources, and both change often.

Is Norton Secure VPN worth it? For most people, yes. Norton Secure VPN’s features, bigger network, and ten-device plans cover more ground, though the US base and IPv6 gap are real trade-offs.

よくある質問
Norton Secure VPN は無料ですか?
No. There’s no free plan. Paid plans start at $3.33/month on our CSV figures, and annual plans include a 60-day refund window.
Norton VPNは私のIPアドレスを隠してくれますか?
Yes. It masks your IP and encrypts traffic through a VPN tunnel. One gap: it doesn’t mask IPv6 addresses, so disable IPv6 if privacy matters.
Norton VPNは信頼できるのか?
For everyday privacy, mostly yes. It uses AES-256 encryption from a long-running security brand. But it’s US-based and keeps some diagnostic logs.
Oyster VPNは良いサービスですか?
It’s a solid budget pick for torrenting and basic browsing. Speeds drop on distant servers, HD streaming can struggle, and its privacy claims haven’t been independently audited.
Oyster VPNの本社はどこにありますか?
OysterVPN is based in Ireland. That puts it outside the 5/9/14 Eyes intelligence-sharing alliances, which privacy-focused users often prefer.
