機能比較
Let’s compare ExpressVPN and StrongVPN across 10 key areas of service.
This breakdown covers everything from strong encryption to streaming access for other users.
| 特徴 | エクスプレスVPN | 強力なVPN |
|---|---|---|
| 開始価格 | 月額2.44ドル | 月額3.97ドル |
| サーバー | 105か国で3,000人以上 | 30カ国以上で950人以上 |
| 独立監査 | ✅ 18件の監査 | ❌ なし |
| キルスイッチ | ✅ ネットワークロック | ✅ |
| 分割トンネル構造 | ✅ 全プラットフォーム対応 | ✅ Androidのみ |
| パスワードマネージャー | ✅ ExpressVPNキー | ❌ |
| クラウドストレージ | ❌ | ✅ 250GB SugarSync |
| 同時接続 | 10~14(計画による) | 12 |
| ブラウザ拡張機能 | ✅ Chrome, Firefox | ❌ |
| 最適な用途 | プライバシーを最優先するストリーミングユーザー | ストレージが必要な予算重視のユーザー |
1. サーバーネットワーク
エクスプレスVPN: Runs over 3,000 vpn servers in 105 countries and 160+ cities. Every server uses 10 Gbps connections. You can connect from almost anywhere on earth. The wide coverage means you’ll always find a server close to your internet connection for fast speeds.
強力なVPN: Offers 950+ physical servers across 30+ countries — a small server network compared to top vpn providers. All strongvpn’s servers are real hardware in the countries they represent. The network covers North America, Europe, and Asia but skips many regions.
2. セキュリティとプライバシー
エクスプレスVPN: Uses AES-256 strong encryption and has completed 18 independent audits. It’s based in the British Virgin Islands, outside any intelligence alliances. TrustedServer wipes all data on every reboot for strong leak protection.

強力なVPN: Also uses AES-256 encryption. Strongvpn claims a strict no logging policy and the only personal information collected is billing details and email for account creation. However, the vpn company is based in the US — part of the Five Eyes alliance — and has never had an independent 監査.
⚠️ 警告: StrongVPN’s US jurisdiction means the government could request data handovers. Without independent dns leak tests and privacy audits, you’re trusting strict no logging policies on the vpn company’s word alone.
3. スピードとパフォーマンス
エクスプレスVPN: The Lightway vpn protocol keeps overall speed loss around 25% on average. It performs well on both nearby and distant vpn locations. Download speeds stay fast enough for 4K streaming, gaming, and large file transfers.
強力なVPN: Average download speeds reach 31% compared to base speeds, and average upload speeds hit 13%. Speeds can drop by 20% on nearby servers. WireGuard helps keep connections fast on supported devices, and it strongly advise users to pick the closest server for the best vpn speeds.
4. ストリーミングアクセス
エクスプレスVPN: Unblocks Netflix in multiple regions, Hulu, BBC iPlayer, Disney+, and Amazon Prime Video. The MediaStreamer feature lets you access content on smart tvs, Android TV, and gaming consoles that don’t run native apps. It works on every streaming service we tried.
強力なVPN: Works with Netflix and Disney+. It can also access Hulu and Amazon Prime on some servers. However, BBC iPlayer can be hit or miss. The bundled StrongDNS helps stream on devices without native apps.
5. スプリットトンネリング
エクスプレスVPN: Split tunneling works on Windows, Mac, Android apps, and routers. You pick which apps use the vpn tunnel and which don’t. The split tunneling feature is very useful for banking on a Windows laptop while streaming with a different ip address.
強力なVPN: Split tunneling is only available on the android app. Windows, Mac, and iOS users don’t get this feature in the settings menu. That’s a big miss for desktop users who want app-level control of browsing activity.
6. 広告ブロックと脅威対策
エクスプレスVPN: Includes Threat Manager to block ads, trackers, and malicious sites. Parental controls let you block adult sites on connected mobile devices. Your browsing history stays private, and connection logs are never stored.

強力なVPN: No built-in ad blocker or threat protection. You’ll need a separate app for ad blocking. StrongVPN focuses on the basic vpn connection only.
7. ボーナス特典
エクスプレスVPN: Comes with the ExpressVPN Keys password manager, Identity Defender, and the Aircove router. The Pro plan includes dedicated ip addresses at no extra cost — useful for remote work and avoiding CAPTCHAs.
強力なVPN: Bundles 250GB of sugarsync cloud storage. That’s a unique perk no other vpn offers. It also includes StrongDNS for smart devices and a basic kill switch for accidental disconnects.
8. アプリとデバイスのサポート
エクスプレスVPN: Native apps for Windows, Mac, iOS, Android, Linux, and Amazon Fire TV. Browser extensions for Chrome and Firefox. Plus the Aircove router for whole-home protection of every internet connection.
強力なVPN: Apps for Windows, Mac, iOS, Android devices, and Amazon Fire TV. Also works on routers and Kodi via setup guides. No browser extension is available, which limits Chrome OS users.
9. カスタマーサポート
エクスプレスVPN: ExpressVPN’s customer support runs 24/7 live chat and email. Response times are fast. The help center has detailed guides for every platform, and the expressvpn faqs page covers most common issues like dns leaks and setup with ExpressVPN’s app.
強力なVPN: Offers live chat, phone, and email customer support. Phone support is rare among other vpns and a nice bonus. However, the チャットボット can be unreliable, so you may need to escalate to email.
10. 価格設定とコスト
Let’s compare the pricing plans of both vpn services side by side.
| プラン | エクスプレスVPN | 強力なVPN |
|---|---|---|
| 毎月 | 月額12.95ドル | 月額11.99ドル |
| 年間 | 月額2.44ドル(基本プラン、2年契約) | 月額3.97ドル(年間契約) |
| Day Money Back Guarantee | 30日間(全プラン共通) | 30日間(年1回のみ) |
| 無料トライアル | 7日間(モバイル) | なし |
エクスプレスVPN: The 2-year Basic plan at $2.44/month is cheaper than StrongVPN’s annual rate. You also get more security tools per dollar with the Advanced and Pro plans. Various payment options are accepted, including credit cards, PayPal, and Apple Pay.
強力なVPN: Simple pricing with just two options. The $3.97/month annual plan is fair. Payment options include credit cards, PayPal, and Alipay. But it lacks the extras that ExpressVPN bundles at a lower price point.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| 最高のプライバシーとセキュリティ | エクスプレスVPN | 18件の監査、BVI管轄区域 |

What Our Review Didn’t Cover
This vs comparison focused on individual users and small teams. We didn’t run dns leak test results across every server, and we didn’t test obscure regional vpn server locations in depth. Enterprise features and bulk licensing weren’t part of this strongvpn review or expressvpn review. If you’re a 仕事 user, your priorities may differ from what we’ve covered here.
