Ireland also follows GDPR, which adds legal privacy protection.
OysterVPN features include an ad blocker, DDoS protection, and a kill switch.

機能比較
Here’s how FastestVPN vs Oyster VPN plays out, one feature at a time. We cover nine key areas, plus pricing.
| 特徴 | 最速VPN | オイスターVPN |
|---|---|---|
| 開始価格 | 月額0.83ドル | 月額5.99ドル |
| 無料プラン | ❌ | ❌ |
| 生涯プラン | ✅ | ✅ |
| 同時接続 | 10 | 5 |
| Audited Logging Policy | ✅ | ❌ |
| スプリットトンネリング | ✅ | ✅ (Windows & Android) |
| 内蔵広告ブロッカー | ✅ | ✅ |
| Linuxアプリ | ✅ | ❌ |
| 24時間年中無休のライブチャット | ✅ | ⚠️限定 |
| 最適な用途 | 予算重視の世帯 | Simple lifetime setup |
1. Server Network & Speed
最速VPN: It runs around 800 servers in 49 countries. NordVPN and エクスプレスVPN offer thousands. Reviewers who tested FastestVPN saw download speed drop about 45% in speed tests. Long-distance links lost up to 55%.
On a nearby server with the WireGuard protocol, one test hit roughly 730 Mbps. Upload speed fell about 22% in another round. Ping stayed flat on one computer but rose 33% on a second. Torrenting works on all FastestVPN servers, but P2P speeds are reported slow.
オイスターVPN: Published counts for OysterVPN’s servers vary. Some reviews list 150+ servers in 17 countries. Others list 400+ servers in 35+ countries.
OysterVPN’s speeds hold up on nearby servers. Connection speeds fall about 55% on distant servers, though. That’s fine for browsing but weak for HD streaming.
⚠️ 警告： With so few servers, both networks can get crowded at peak times. Pick the fastest server near you and run a speed test first. A slow home connection stays slow through any VPN.
2. ストリーミングパフォーマンス
最速VPN: FastestVPN’s servers include dedicated streaming servers, plus a streaming tab inside the app. Reviewers testing FastestVPN reached Netflix US, UK, Japan, and Sweden. Disney+, BBC iPlayer, Hotstar, Prime Video, and Hulu also worked.
Is streaming FastestVPN’s strong suit? Partly. Australian Netflix failed, US Netflix sometimes loaded slowly, and some streaming sites needed a refresh.
オイスターVPN: It unblocks popular streaming services like Netflix, Max, ESPN+, and BBC iPlayer. It struggles with Hulu and Disney+. Day-to-day browsing is fine, but 4K on long-distance servers is a stretch.
3. 暗号化とVPNプロトコル
最速VPN: It uses AES-256 encryption. You can choose WireGuard, OpenVPN TCP, IKEv2, or an Auto mode that picks for you.
オイスターVPN: It also uses AES-256. It lists WireGuard, OpenVPN, and IKEv2 as secure VPN protocols.
Here’s how FastestVPN presents its protocol choices.
And here’s the protocol menu inside OysterVPN.
⚠️ 警告： Reports conflict on OysterVPN’s WireGuard support. Some reviews say it’s missing. Check the protocol menu in your app before you rely on it.
4. No-Logs Policy & Jurisdiction
最速VPN: FastestVPN claims it keeps no activity or connection logs. Altius IT audited that claim. Being based in the Cayman Islands, it faces no data retention rules. That audit is a real edge at this price.
オイスターVPN: It promises a zero logging policy. It says it never stores browsing data or DNS requests. But it hasn’t had a third-party audit. GDPR helps, yet you’re trusting the company’s word.
5. Leak Protection & Kill Switch
最速VPN: It routes DNS queries through its own servers for DNS leak protection. A kill switch cuts traffic if the VPN connection drops. Still, some reviews report DNS leaks on Windows and 質問 the kill switch.
オイスターVPN: Its IP leak protection also blocks DNS and WebRTC leaks. The internet kill switch stops traffic when the tunnel fails. That prevents accidental data leaks.
A kill switch is a crucial feature on public Wi-Fi. Here’s FastestVPN’s version.
OysterVPN’s switch runs quietly in the background.
⚠️ 警告： Run DNS leak tests after setup, especially on a Windows computer. Data leaks can expose your real IP address.
6. Split Tunneling & Smart Tunneling
最速VPN: It offers app-based split tunneling on Windows and Android. Smart tunneling goes further. You pick websites that always use the VPN, even before you open the app.
オイスターVPN: The split tunneling feature lets browser traffic use the VPN while banking apps stay direct. It’s only on Windows and Android, so Mac and iPhone users miss out.
7. Simultaneous Connections & Devices
最速VPN: It allows 10 simultaneous connections, with more at $4 each per month. FastestVPN apps cover Windows, Mac, Android, iOS, and Linux. Its Windows and Mac apps share a clean layout. Android users get the most settings, while the FastestVPN iOS app stays basic.
オイスターVPN: It caps you at five connections, with no unlimited connections option. The OysterVPN apps cover multiple devices on Windows, Mac, iOS, and Android. Its Android app and iOS app mirror the desktop app. There’s no native Linux app and no app for smart TVs or consoles.
Both offer intuitive apps for beginners. FastestVPN’s apps also have a router setup, which covers Apple TV and other streaming devices.
8. 追加のセキュリティツール
最速VPN: It adds a NAT firewall, malware protection, and an ad blocker. FastestVPN’s ad blocker removes most page ads. Double VPN servers route traffic through two locations for extra privacy.
オイスターVPN: It includes an ad and malware blocker too. DDoS protection shields gamers from flooding attacks. These are advanced security features for a budget app.
💡 プロのヒント: Neither VPN replaces antivirus software. Keep a separate scanner on every device.
9. カスタマーサポート
最速VPN: It offers 24/7 live chat with real people, plus email. Replies come fast, but answers can feel generic. The knowledge base has setup guides, though its search works poorly.
オイスターVPN: Its customer support is thinner. There’s no phone line, and reviews say live chat is missing or limited. Email replies are reported as slow. Where chat support appears, it may log your IP.
10. 価格設定とコスト
プランを並べて比較してみましょう。
| プラン | 最速VPN | オイスターVPN |
|---|---|---|
| 無料 | ❌ | ❌ |
| 毎月 | 1 Month Plan: $5/mo | 1-Month +2 Months free: $5.99/month |
| 年間 | 1 Year + 1 Year Free: $0.83/mo | 1-Year: $29.99/month |
| 一生 | Exclusive Lifetime Plan: $40 | Lifetime Access: $59.99/month |
| 返金期間 | 31日間 | 30日間 |
最速VPN: It costs less on every plan. The lifetime deal is a single $40 payment. Dedicated IPs and port forwarding stay optional.
オイスターVPN: It costs more at each tier. Its lifetime option still pays off if you’ll use a VPN for years.

| 必要な場合は | 選ぶ | なぜ |

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 browsing, streaming, and torrenting for individuals and families. We didn’t check whether any server locations run on virtual servers. We also didn’t test either VPN in restrictive countries. Reports say OysterVPN doesn’t work reliably in China.
Router setups, 仕事 use, and add-on performance weren’t covered either. Everything here reflects October 2026 versions, so features may change.

FastestVPN and OysterVPN chase the same budget buyer. FastestVPN gives you more for less. You get double the device slots, an audited policy, and cheaper plans.
OysterVPN is a decent VPN for simple setups. For basic online security, it gets the job done. DDoS protection and its Irish base are real strengths for gamers.
Keep expectations modest on long-distance links. Despite the name, neither is the fastest VPN around. Both suffer slow speeds far from home.
