1. サーバーネットワーク
エクスプレスVPN: Runs 3,000+ servers across 105 countries. You’ll find servers on every continent. This massive network means less crowding and faster speeds no matter where you connect.
オイスターVPN: Offers about 350+ servers in 35 countries. Most are in North America and Europe. Coverage in Africa and the Middle East is very limited with just one server location each.
2. 速度とパフォーマンス
エクスプレスVPN: Loses only about 25% speed on average when connected. The Lightway protocol keeps connections fast and stable. Even distant servers load websites and videos quickly.
オイスターVPN: Speeds are decent on nearby servers. But distant servers can drop speed by 55% or more. Upload speeds are especially weak at about 38% of the base speed.
💡 Test Result: ExpressVPN held steady speeds across US, UK, and Asian servers. OysterVPN performed well in nearby locations like Dublin but struggled with servers in Asia and South America.
3. セキュリティとプライバシー
エクスプレスVPN: Uses AES-256 encryption with 18 independent security audits to verify its no-logs policy. TrustedServer technology ensures all data is wiped on every server reboot. Based in the British Virgin Islands with strong privacy laws.
オイスターVPN: Also uses AES-256 encryption and claims a no-logs policy. But it has zero independent audits to prove those claims. Based in Ireland, which is outside the 5/9/14 Eyes Alliances. Recently moved to RAM-only servers.
⚠️ Warning: OysterVPN’s privacy policy has been flagged by reviewers for being vague. Some reports suggest it may log your full name. Without an 監査, you’re trusting OysterVPN on their word alone.
4. Streaming Access
エクスプレスVPN: Unblocks 100+ streaming services including Netflix, Hulu, Disney+, BBC iPlayer, and Amazon Prime Video. Works across all platforms. The MediaStreamer feature brings streaming to smart TVs and gaming consoles.
オイスターVPN: Can unblock Netflix, BBC iPlayer, and ESPN+. But it struggles with Hulu and Disney+. Dedicated streaming servers are only in the US and UK. No smart TV or gaming console app.
5. VPNプロトコル
エクスプレスVPN: Offers its own Lightway protocol plus OpenVPN and IKEv2. Lightway is open-source and audited for security. It connects in under a second and uses less battery on phones.
オイスターVPN: Supports WireGuard (added in 2025), OpenVPN, and IKEv2. WireGuard is not yet available on Android. No proprietary protocol like ExpressVPN’s Lightway.
6. スプリットトンネリング
エクスプレスVPN: Split tunneling works on Windows, マック, Android, and routers. Choose which apps use the VPN and which bypass it. Handy for banking apps or local services.
オイスターVPN: Split tunneling is limited to Windows and Android only. Mac and iOS users don’t get this feature. That’s a big gap for Apple users.
7. Device Connections
エクスプレスVPN: Allows up to 14 devices on the Pro plan. The Basic plan covers 10 devices. You can also install it on routers to protect your whole home network at once.
オイスターVPN: Allows only 5 devices at the same time. That may not be enough for families. No router app is available to extend coverage.
8. カスタマーサポート
エクスプレスVPN: Has 24/7 live chat and email support. Response times average about 30 seconds. Support agents are knowledgeable and helpful.
オイスターVPN: Offers 24/7 live chat and email support. But live chat can be slow or unresponsive at times. Email responses may take several hours.
9. Torrenting and P2P
エクスプレスVPN: P2P file sharing works on all servers. Fast download speeds make torrenting smooth. The kill switch keeps your IP hidden if the connection drops.
オイスターVPN: Also supports torrenting on all servers. Has dedicated P2P servers for better performance. DDoS protection adds an extra layer of safety for heavy downloaders.
10. Pricing & Cost
Let’s compare the pricing plans side by side.
| プランの種類 | エクスプレスVPN | オイスターVPN |
|---|---|---|
| 毎月 | $12.95/mo (Basic) | $5.99/mo |
| 1年 | $2.44/mo (Basic, 2-yr) | $29.99 total |
| 一生 | ❌ Not available | $59.99 one-time |
| Money-Back | 30 days | 30 days |
| 無料トライアル | 7-day (iOS/Android) | ❌ None |
エクスプレスVPN: The 2-year Basic plan at $2.44/mo is the best deal. You get 4 free months included. The Advanced plan at $3.14/mo adds a password manager and identity monitoring. Premium but packed with features.
オイスターVPN: The lifetime deal at $59.99 is the standout. Pay once and never worry about renewals. The monthly plan at $5.99 is cheaper than most VPNs. But you get fewer features for the price.
