🏆 Winner: ExpressVPN

- Password Manager Included: The ExpressVPN Keys password manager comes bundled with every subscription at no extra cost.
ExpressVPN Pros & Cons

Bitdefender VPN とは何ですか?
Bitdefender VPN is a virtual private network service built by Bitdefender.
Bitdefender is a Romania-based cybersecurity company known for its antivirus software.
The VPN is powered by the Catapult Hydra protocol — the same tech behind ホットスポットシールド.
It runs over 4,000 servers across 54 countries and allows up to 10 simultaneous device connections.
Bitdefender VPN is most useful when bundled with Bitdefender’s security suite products.
ビットディフェンダーVPN

⚠️ Warning: Bitdefender VPN does not support Linux or routers. If you need VPN protection on those デバイス, you’ll need a different service entirely.

- Antivirus Bundle Value: Bitdefender bundles VPN with one of the best antivirus suites in the market. You get more protection tools per dollar.
- AES-256 Encryption: Bitdefender VPN uses military-grade AES-256 encryption to secure your connection. This is the same standard used by governments.
- Ad Blocker & Anti-Tracker: Built-in tools block intrusive ads and trackers automatically. These features are usually paid add-ons in competing VPNs.
- Beginner-Friendly Interface: The app is clean and simple across all platforms. Non-technical users can get connected in seconds.

機能比較
Ready to see how ExpressVPN and Bitdefender VPN stack up feature by feature?
We compared 10 key categories to help you pick the right VPN for your needs.
| 特徴 | エクスプレスVPN | ビットディフェンダーVPN |
|---|---|---|
| 開始価格 | $2.44/mo | $59.99/yr ($5/mo) |
| 無料プラン | ❌ | ✅ (200MB/day limit) |
| Server Count | 3,000+ servers | 4,000+ servers |
| Country Coverage | 105 countries | 54 countries |
| Streaming (Netflix, Disney+) | ✅ | ❌ |
| キルスイッチ | ✅ | ✅ |
| No-Logs Policy (Audited) | ✅ (18 audits) | ⚠️ Vague policy |
| スプリットトンネリング | ✅ | ✅ |
| Linux / Router Support | ✅ | ❌ |
| 最適な用途 | Privacy + streaming power users | Bitdefender antivirus bundle users |
1. Server Network & Coverage
エクスプレスVPN: ExpressVPN operates 3,000+ servers spread across 105 countries. This level of coverage is hard to match — you can connect from virtually any corner of the globe. For travelers and remote workers, this is a huge advantage.
ビットディフェンダーVPN: Bitdefender runs more than 4,000 servers, but they’re limited to just 54 countries. The higher server count sounds impressive, but the narrower geographic spread means fewer location options — especially in Asia and Latin America.
⚠️ Warning: More servers don’t always mean better coverage. Country count matters more for accessing region-specific content — ExpressVPN wins here by a wide margin.
2. Speed & Performance
エクスプレスVPN: ExpressVPN’s Lightway protocol keeps speed loss to around 25% on most servers. This is excellent performance for a premium VPN. The open-source protocol has been independently audited for security and reliability.
ビットディフェンダーVPN: Bitdefender uses the Catapult Hydra protocol, which performs well on nearby servers. However, performance decreases noticeably when connecting to distant locations like 日本 or Australia. It’s decent for everyday browsing but not ideal for latency-sensitive tasks.
💡 Test Result: ExpressVPN maintained more stable speeds across international servers. Bitdefender VPN struggled on Asia-Pacific connections specifically.
3. Streaming & Geo-Unblocking
エクスプレスVPN: ExpressVPN reliably unblocks Netflix, Disney+, Hulu, BBC iPlayer, and Amazon Prime Video. It even supports devices that don’t natively support VPNs — like smart TVs and gaming consoles — through its MediaStreamer DNS feature.
ビットディフェンダーVPN: Bitdefender VPN struggles badly with streaming. It cannot unblock Netflix US, Disney+, or Amazon Prime Video. It can access BBC iPlayer in some cases, but that’s about it. If streaming is your priority, this is a dealbreaker.
✅ 結果： ExpressVPN is the clear winner for streaming. Bitdefender VPN simply does not support the major platforms most users want.
4. Security & Privacy
エクスプレスVPN: ExpressVPN has undergone 18 independent security audits to verify its no-logs policy. It uses AES-256 encryption and its TrustedServer technology wipes all data on every server reboot. The Lightway protocol is also open-source and audited.
ビットディフェンダーVPN: Bitdefender uses AES-256 encryption and a kill switch. However, its privacy policy is vague — it does log some technical data for fraud prevention. There’s no dedicated VPN-specific 監査 on record, which is a concern for privacy-focused users.
⚠️ Warning: Bitdefender’s privacy policy lacks the clarity that independent audits provide. If zero-logs verification matters to you, ExpressVPN is the safer choice.
5. Ad Blocker & Extra Tools
エクスプレスVPN: ExpressVPN includes a Threat Manager feature that blocks trackers and malicious sites. Higher-tier plans add an ad blocker, identity defender, and the ExpressVPN Keys password manager — all bundled at no extra cost.
ビットディフェンダーVPN: Bitdefender includes a built-in ad blocker and anti-tracker feature across all plans. Since Bitdefender is primarily a security company, these tools are well-developed. Bundling them with the VPN adds real value — especially for users who already pay for the Bitdefender security suite.
6. Device & Platform Support
エクスプレスVPN: ExpressVPN supports Windows, macOS, iOS, Android, Linux, and routers. It works on smart TVs and gaming consoles via MediaStreamer. This makes it one of the most versatile VPNs available for multi-device households.
ビットディフェンダーVPN: Bitdefender VPN supports Windows, macOS, iOS, and Android — but nothing else. There’s no Linux support, no router compatibility, and no smart TV app. This severely limits who can use it in a modern multi-device setup.
⚠️ Warning: If you run Linux, want VPN on your router, or need coverage on smart TVs, Bitdefender VPN is not an option. ExpressVPN covers all these cases.
7. Kill Switch & DNS Leak Protection
エクスプレスVPN: ExpressVPN’s Network Lock kill switch cuts your internet if the VPN drops. This prevents your real IP from ever being exposed. It’s available on all platforms and activates automatically.
ビットディフェンダーVPN: Bitdefender VPN also includes an automatic kill switch on all platforms. However, some users have reported inconsistent DNS leak protection in independent tests. This is a concern for users who depend on leak-proof connections.
8. スプリットトンネリング
エクスプレスVPN: ExpressVPN’s split tunneling lets you choose which apps route through the VPN and which connect directly. This is useful for accessing local banking apps while streaming international content simultaneously.
ビットディフェンダーVPN: Bitdefender VPN also supports split tunneling. You can choose which apps or domains bypass the VPN tunnel. This feature works well in practice and is easy to configure through the app.
9. カスタマーサポート
エクスプレスVPN: ExpressVPN offers 24/7 live chat and email support. Response times are fast and agents are knowledgeable specifically about VPN issues. The support team can help find the right server for streaming if you run into problems.
ビットディフェンダーVPN: Bitdefender provides live chat, email, and phone support available 24/7. However, the support team handles all Bitdefender products — not VPN specialists. Email responses can take at least 30 minutes, and VPN-specific help can be hit or miss.
10. Pricing & Cost
Let’s compare the pricing plans side by side.
| プランレベル | エクスプレスVPN | ビットディフェンダーVPN |
|---|---|---|
| Entry Plan | Basic — $2.44/mo | Total Security — $59.99/yr |
| Mid Plan | Advanced — $3.14/mo | Premium Security — $79.99/yr |
| Top Plan | Pro — $5.24/mo | Ultimate Security Plus — $119.99/yr |
| Free Option | ❌ (30-day money-back) | ✅ (200MB/day with Bitdefender package) |
エクスプレスVPN: ExpressVPN’s entry price of $2.44/mo is competitive for a premium VPN. You get dedicated VPN-only plans with clear feature tiers. The per-month pricing is straightforward and includes a 30-day money-back guarantee.
ビットディフェンダーVPN: Bitdefender’s pricing bundles VPN with its full security suite. If you already pay for Bitdefender antivirus, the VPN is essentially included. But if you only want a VPN, you’re paying for tools you may not need.
Different Scenarios
| If You Need… | Choose | Why |
|---|---|---|
| Reliable streaming access | エクスプレスVPN | Unblocks Netflix, Disney+, Hulu |
| Tight annual budget | ビットディフェンダーVPN | Bundled with antivirus for $59.99/yr |
| Linux or router support | エクスプレスVPN | Only ExpressVPN supports both |
| Verified zero-logs policy | エクスプレスVPN | 18 independent audits confirm it |
| 10 simultaneous devices | ビットディフェンダーVPN | Allows 10 connections per plan |
| Already a Bitdefender user | ビットディフェンダーVPN | VPN included in existing subscription |
| International 旅行 coverage | エクスプレスVPN | Covers 105 countries vs 54 |
💰 Your Budget
ExpressVPN starts at $2.44/mo for a dedicated VPN plan. Bitdefender VPN is cheaper only if you already pay for the security suite — otherwise you’re paying more for tools you don’t need.
🔌 Your Tech Stack
ExpressVPN works on Windows, macOS, iOS, Android, Linux, routers, smart TVs, and gaming consoles. Bitdefender VPN only supports Windows, macOS, iOS, and Android — choose accordingly.
📺 Your Streaming Needs
If you want to watch geo-restricted Netflix, Disney+, or Hulu, ExpressVPN is the only real choice. Bitdefender VPN cannot reliably unblock these major platforms.
🎓 Your Experience Level
Both VPNs are beginner-friendly. Bitdefender’s interface is slightly simpler, but ExpressVPN is not far behind. Either option works well for first-time VPN users.
🆓 Free Trials and Demos
Bitdefender offers a 200MB/day free plan — enough for light browsing but not streaming. ExpressVPN has no free plan but gives you 30 days to test it risk-free with a money-back guarantee.
🛟 Support Options
ExpressVPN’s 24/7 live chat is staffed by VPN-specific agents. Bitdefender’s support covers all products, so VPN questions may take longer to resolve with less specialized help.
