⚡ 簡単な評価:
- 価格: Bitdefender bundles start at $59.99/yr. A StrongVPN subscription starts at $3.97/month on the annual plan.
- 最適な用途: ビットディフェンダー VPN suits people who already want antivirus. StrongVPN suits router owners and heavy streaming platforms users.
- 主な違い： Bitdefender VPN runs 4,000+ servers in 54 countries. StrongVPN runs over 950 servers in 30 countries.
- 管轄： Bitdefender sits in Romania, outside 5 Eyes. StrongVPN is US-based, inside the Five Eyes alliance.
- 私たちのおすすめ： Bitdefender VPN, for its bigger server network and friendlier privacy jurisdiction.
Two very different companies built these two products.
Bitdefender is an antivirus brand that added a virtual private network.
StrongVPN has been providing VPN services since 2005.
That gap shapes almost every difference you will read below.
One sells 安全 as a bundle. The other sells a standalone VPN service.

StrongVPNとは何ですか？
StrongVPN is a standalone VPN service from a US-based VPN company.
It has been in the VPN industry since 2005.
Strong VPN routes your web traffic through its own physical servers.
StrongVPN does not use virtual server locations at all.
Every subscription also bundles 250GB of SugarSync cloud storage.
That free cloud storage is unusual for a VPN provider at this price.
The video below walks through the Windows app and the settings menu.
強力なVPN
Twelve simultaneous connections and native apps for every major platform. Routers, WireGuard, and StrongDNS are all included. Comes with 250GB of cloud storage.

Pricing is simple here. There are only two plans.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 年間計画 | 月額3.97ドル | 長期利用で最低価格を求めるユーザー |
| 月額プラン | 月額11.99ドル | Short trips and month-to-month flexibility |
Pricing verified September 2026.
無料トライアル: None. StrongVPN does not offer a free trial or a free version.
返金保証： 30 days on every StrongVPN subscription.
📌 注記： Payment methods include credit cards, PayPal, and Alipay. Both plans carry identical security features, so the cheaper tier is not a stripped-down one.
⚠️ Renewal warning: The annual price rises to $89.99 after year one. Public listings also show $10.99 monthly and $69.99 yearly in some regions. We kept the CSV figures above and flagged the difference here.

- SmartDNS included: It bypasses geo restricted content without any speed reduction.
- Wide device support: Native apps for iOS, Windows, macOS, アンドロイド, and routers. Setup guides cover the rest.
- Real server locations: All servers are physically located in the countries they represent.
- Cloud storage bonus: 250GB of SugarSync storage ships with the plan at no extra cost.
- Nearby speed: Download speed retention on nearby servers shows only a 5-7% speed loss.

機能比較
Both VPN providers cover the basics well. The gaps show up once you look closely at protocols, server locations, and device support. Here are ten areas that decide the match.
| 特徴 | ビットディフェンダーVPN | 強力なVPN |
|---|---|---|
| 開始価格 | $59.99/yr bundle | $3.97/month annual |
| 無料版 | ✅ 200MB daily | ❌ |
| サーバー | 54か国で4,000人以上 | 30か国で950以上 |
| 同時接続 | 10 | 12 |
| WireGuardとOpenVPN | ❌ | ✅ |
| ルーターのサポート | ❌ | ✅ |
| キルスイッチ | ✅ | ✅ |
| スプリットトンネリング | ✅ | ✅ |
| 独立監査 | ❌ | ❌ |
| 最適な用途 | Antivirus users wanting online security | Router owners and streaming platforms |
1. Encryption and Online Security
ビットディフェンダーVPN: AES-256 encryption secures every session, backed by an automatic kill switch that blocks internet traffic the moment a tunnel drops. The ad blocker and anti-tracker screen out online threats and intrusive scripts before they load. Public Wi-Fi protection kicks in on unsecured networks without you touching anything.
強力なVPN: It also uses AES-256 encryption to protect user データ, plus a kill switch that severs your internet connection if the VPN drops. DNS leak protection is built in, and independent leak tests have come back clean. The security features are solid but plain compared with what specialist providers now ship.
2. Logging Policy and Online Privacy
ビットディフェンダーVPN: The no-logs policy says it stores no traffic logs, no IP addresses, and no browsing history. It does keep some technical data for fraud prevention, including hashed user and device IDs stored as randomly generated tokens. There is no separate logging policy for the VPN service, and the wording stays vague.
強力なVPN: It runs a strict no logging policy and does not record browsing activity, timestamps, or IP addresses. The only personal information it collects is billing details and an email address. The catch is jurisdiction: it is US-based, inside the Five Eyes alliance, and the policy has never been audited.
⚠️ 警告： Neither VPN company has published an independent audit. Both use strict no logging policies on paper only. If verified privacy is your top requirement, we strongly advise looking at audited providers instead.
3. VPNプロトコル
ビットディフェンダーVPN: The service leans on Catapult Hydra, the proprietary protocol licensed from ホットスポットシールド. Catapult Hydra is tuned for fast, stable connections and it delivers on nearby routes. Documentation also lists industry-standard options such as WireGuard and OpenVPN, though Catapult Hydra remains the default on desktop.
強力なVPN: You get five choices: WireGuard, OpenVPN, IKEv2, SSTP, and L2TP. That range matters on restrictive networks where one VPN protocol gets blocked and another walks straight through. Switching takes a few taps in the settings menu.
4. Server Network and Server Locations
ビットディフェンダーVPN: Over 4,000 servers across 54 countries gives you a lot of reach. More servers usually means shorter hops and better ping times. The app can connect to the server closest to you or you can ブラウズ the full server list yourself.
強力なVPN: Over 950 servers in 30 countries is a small server network by 2026 standards. The upside is that StrongVPN’s servers are all physical, never a rented virtual location. P2P transfers are allowed on every one of them.
5. Speed and Download Speeds
ビットディフェンダーVPN: Catapult Hydra is known for fast speeds on a nearby VPN server. Performance drops noticeably on distant routes, especially 日本 and Australia. It is not the fastest VPN available, and it trails NordVPN and エクスプレスVPN on raw throughput.
強力なVPN: Nearby connections lose only 5-7% of base download speeds, which is good. Longer routes are harsher: average download speed measured 31 percent of base speed, and upload speeds fell to 13 percent. Latency runs higher than the fastest rivals, so competitive gaming is not its strength.
💡 プロのヒント: Both apps slow down over distance. Connect to a UK server for British content and a local one for everything else. Switching takes a few seconds and keeps connection times low.
6. Streaming Platforms and Geo Restricted Content
ビットディフェンダーVPN: Documentation says it supports P2P and unblocks Netflix and Disney+, but real-world results contradict that. BBC iPlayer works. US Netflix, Amazon Prime Video, and Disney+ mostly do not. There are no dedicated streaming servers, and no Apple TV or Fire TV Stick apps to install.
強力なVPN: It safely reaches major streaming platforms from anywhere, with minimal buffering in testing. StrongDNS handles geo restricted content without routing everything through the VPN tunnel. Amazon Fire TV setup guides make it easy to get onto a TV.
7. Apps, Mobile Devices and Platform Support
ビットディフェンダーVPN: App compatibility is limited to Windows, macOS, Android, and iOS. There is no Linux client and no router firmware, so anything outside those four is out of reach. The mobile apps are clean, and desktop notifications tell you when a session starts.
強力なVPN: Native apps cover iOS, Windows, macOS, and Android devices, plus routers and Chrome OS through manual setup guides. The Android app comes straight from the Google Play Store. Devices StrongVPN cannot reach natively usually have a guide, though there are no browser extensions.
8. Ease of Use and Additional Features
ビットディフェンダーVPN: The app is clean and beginner friendly. You sign in through your Bitdefender Central account, hit connect, and you are online in a few seconds. Split tunneling and the ad blocker sit one tap away, and Bitdefender’s instructions cover setup on every supported platform.
強力なVPN: The interface is simple, with a favorites system for the locations you use most. It does offer split tunneling on the main platforms. The latest version keeps the same layout on desktop and on Android apps, so nothing needs relearning.
9. カスタマーサポート
ビットディフェンダーVPN: Live chat runs 24/7, and phone support lists numbers for different countries. Email replies can take at least half an hour. The support team handles every Bitdefender product, so you reach a general support team rather than VPN specialists.
強力なVPN: Support comes through live chat, phone, and email. The knowledge base is built around setup guides for routers and other awkward hardware, which is where other users usually get stuck.
10. 価格設定とコスト
Here are the two price lists side by side.
| プラン | ビットディフェンダーVPN | 強力なVPN |
|---|---|---|
| Entry tier | トータルセキュリティ：年間59.99ドル | Annual Plan: $3.97/month |
| 中級クラス | プレミアムセキュリティ：年間79.99ドル | Monthly Plan: $11.99/month |
| Upper tier | 究極のセキュリティ：年間89.99ドル | ❌ |
| 最高級 | アルティメットセキュリティプラス：年間119.99ドル | ❌ |
| Money back guarantee | 30日間 | 30日間 |
ビットディフェンダーVPN: You are buying a security suite, not just a VPN connection. At $59.99/yr the antivirus, the tunnel, and the ad blocker all arrive together. That is fair value if you needed antivirus anyway, and poor value if you only wanted premium VPN access.
強力なVPN: $3.97/month on the annual plan is a genuinely low entry price for a standalone VPN service. Add the cloud storage and the 12 device allowance and the value holds up. Just budget for the renewal jump in year two.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| Antivirus plus a VPN | ビットディフェンダーVPN | One bundle covers both |
| Router or Chrome OS coverage | 強力なVPN | Bitdefender has no router support |
| ほとんどのサーバー設置場所 | ビットディフェンダーVPN | 4,000台以上のサーバー、54か国 |
| Reliable streaming platforms | 強力なVPN | SmartDNS and wider unblocking |
| Lowest standalone price | 強力なVPN | $3.97/month on the annual plan |
| A safer legal jurisdiction | ビットディフェンダーVPN | Romania sits outside 5 Eyes |
💰 あなたの予算
If a VPN connection is all you want, StrongVPN costs less up front. If antivirus is already in your budget, the Bitdefender bundle absorbs the VPN for free.
🔌 あなたの技術スタック
Bitdefender only runs on Windows, macOS, Android, and iOS. Anyone with Linux boxes, routers, or a Fire Stick needs StrongVPN.
📺 あなたのストリーミング習慣
Bitdefender handles BBC iPlayer but stumbles on US Netflix and Prime Video. StrongVPN opens more of those doors with less friction.
🎓 あなたの経験レベル
Both apps are beginner friendly and take one click to connect. Bitdefender hides more of the settings, which suits people who never want to touch a VPN protocol.
🆓 無料トライアルとデモ
Neither one has a real free trial. Bitdefender offers a 200MB daily free tier with an active licence, and both refund inside 30 days.
🛟 サポートオプション
Bitdefender runs 24/7 live chat and phone support across many countries. StrongVPN’s help centre is smaller but far better on router setup.

私たちのレビューで取り上げられなかったこと
We focused on individuals and small households. We did not test 仕事 licensing, dedicated IP addresses, or long-term torrenting loads. We also could not verify either no-logs claim, since neither VPN company has published an independent audit. If you are buying for a team or routing an office through one VPN tunnel, your results may differ from ours.

🏆 WINNER: BITDEFENDER VPN
Bitdefender VPN wins 5 of 9 categories.
最適な用途: Everyday online privacy, public Wi-Fi safety, households that also need antivirus
These are not really the same product. Bitdefender VPN is a security suite with a tunnel attached. StrongVPN is a VPN provider that does one job.
Bitdefender wins on the things most people never check until they matter: server count, jurisdiction, and support hours. It is the safer default for staying safe online.
StrongVPN is the better buy for one specific reader. If you own a router you want to protect, watch a lot of geo-locked video, and do not want antivirus, it is the stronger fit at a lower price.

よくある質問
Bitdefender VPNは信頼できるのか？
Mostly. It keeps no traffic logs and sits in Romania, outside 5 Eyes. The privacy policy is vague, though, and no independent audit has confirmed those claims.
Bitdefender VPNの月額料金はいくらですか？
Bought alone, the premium VPN runs $6.99 per month or $39.99 for the first year. Our stored bundle pricing starts at $59.99 yearly and adds antivirus.
StrongVPNは無料ですか？
No. There is no free version and no free trial. The annual plan costs $3.97 monthly, the rolling plan $11.99, and both carry a 30-day refund.
StrongVPNには何台のデバイスを接続できますか？
Twelve at once on a single account. That covers mobile devices, desktops, and a router, which effectively protects every gadget behind your home network too.
NordVPNはStrongVPNより優れていますか？
For most people, yes. It has more servers, audited no-logs claims, and faster long-distance routes. The cheaper option still wins on simplicity and bundled cloud storage.
