⚡ 簡単な評価:

But one owns every server it runs, and the other bundles cloud storage.
That single split shapes who should buy which.
Here’s how they compare on privacy, speed, streaming, and price.

VyprVPNの主なメリット
Here’s what makes VyprVPN worth a look:
- カメレオンプロトコル： It scrambles VPN metadata so deep packet inspection can’t flag it. That helps where networks block VPN traffic.
- 自社所有サーバー： VyprVPN’s servers (700+ in 70 locations) are all company-owned. No third-party web host sits in the middle.
- VyprDNS: Its own zero-knowledge DNS servers handle your DNS requests. That stops DNS leaks and tampering.

1. セキュリティと暗号化
VyprVPN: VyprVPN wraps every connection in modern, strong encryption. That shields you from hackers, identity theft, and malware on shared networks. Public WiFi protection turns the VPN on the moment you join an untrusted network.
強力なVPN: StrongVPN uses AES-256 encryption to protect your data. It’s the same cipher most paid VPNs rely on. The strong encryption keeps your web traffic hidden from your ISP. That’s solid digital security for everyday use.
2. No-Logs Policy & Privacy
VyprVPN: It doesn’t log user IP addresses, destination IPs, connection times, traffic, or DNS requests. Leviathan Security Group audited that claim in 2018, and VyprVPN passed. But no new audit has followed, and the Certida takeover brought a more generic policy.
強力なVPN: StrongVPN claims a strict no logging policy. It covers your online activity, browsing history, timestamps, and IP addresses. The only personal information it keeps is your email and payment information. It says it never sells that data to third parties.
⚠️ 警告： StrongVPN has never had an independent audit, and it sits in a Five Eyes country. Both brands advertise strict no logging policies. Only VyprVPN has outside proof, even if it’s dated.
3. VPNプロトコル
VyprVPN: VyprVPN supports WireGuard and OpenVPN, plus its own Chameleon protocol. Third-party tests show WireGuard reaching 300–325Mbps, well ahead of OpenVPN. That covers the needs of most VPN users.
強力なVPN: StrongVPN supports WireGuard, OpenVPN, IKEv2, SSTP, and L2TP. That’s the longer list of the two. Beginners can stay on WireGuard, while tinkerers switch in the settings menu.
4. Censorship & VPN Blocking
VyprVPN: VyprVPN’s Chameleon protocol hides VPN traffic from deep packet inspection. Obfuscated servers also stop your traffic from leaking to your provider’s network. Results vary by country, but it’s the stronger pick where VPN blocks are common.
強力なVPN: StrongVPN markets its apps as a way to avoid censorship. But its documentation describes no custom Chameleon protocol or obfuscation mode. Standard protocols are easier for strict firewalls to spot.
5. キルスイッチと漏水防止機能
VyprVPN: The kill switch blocks your internet whenever the VPN connection drops. Your IP address stays hidden until it reconnects. According to Tom’s Guide, though, VyprVPN’s iOS app lacks a kill switch.
強力なVPN: StrongVPN also cuts your connection on drops. It adds DNS leak protection so requests stay inside the tunnel. Its identity tools keep your browsing activity away from other users on public networks.
💡 プロのヒント: We strongly advise running your own leak tests after setup. Free tools check for DNS leaks and confirm IP leak protection works.
6. DNS Features
VyprVPN: VyprVPN runs its own zero-knowledge DNS servers, called VyprDNS. No third party ever sees your lookups. You can also set a custom DNS in the app.
VyprDNS also doubles as built-in protection against DNS leaks.
強力なVPN: StrongVPN offers StrongDNS plus a smart DNS service. Smart DNS gets around geo-blocks without the speed hit of full encryption. It’s handy on Apple TV and other devices without native apps.
7. Split Tunneling & App Support
VyprVPN: VyprVPN calls its split tunneling “Connection Per App.” You pick which apps use the VPN. VyprVPN supports Windows, マック, iOS, Android, Android TV, and routers. Tom’s Guide notes split tunneling skips Mac and iOS.
強力なVPN: Both brands offer split tunneling, but StrongVPN limits it to its Android apps. The devices StrongVPN supports include Windows, macOS, iOS, Android, Amazon Fire TV, and routers. Manual setup guides help with anything else.
On Chrome OS, you can grab either Android app from the Google Play Store. Neither brand offers browser extensions, so you’ll rely on the desktop apps.
8. Server Network & Speed
VyprVPN: VyprVPN runs 700+ servers in 70 server locations, including spots across South America and Asia. Speeds can drop 38% on nearby servers and up to 77% on distant ones. Stick to a local server for the best results.
強力なVPN: StrongVPN’s servers number 950+, so it has more servers, but they cover just 30 countries. Some third-party tests show only 5–7% speed loss nearby, while others report around 20%. One test even measured downloads at 31% of base speed and upload speeds at 13%.
💡 プロのヒント: Connect to the server closest to you. A nearby server with light server load usually gives the fastest speeds.
9. Streaming
VyprVPN: VyprVPN can unblock US Netflix, BBC iPlayer, Amazon Prime Video, and Disney Plus. It struggles with Hulu, ITVX, and Netflix in Australia, Canada, 日本, and the UK. HD plays smoothly, but 4K can stutter.
強力なVPN: StrongVPN reaches major streaming platforms with minimal buffering in third-party tests. P2P is allowed on every server, and bandwidth usage isn’t capped. Its higher latency makes it a weaker pick for competitive gaming, though.
10. 価格設定とコスト
Here are both price lists side by side.
| プラン | ヴィプVPN | 強力なVPN |
|---|---|---|
| 無料 | ❌ | ❌ |
| 毎月 | 月額5ドル | 月額11.99ドル |
| 1-Year / Annual | 月額4ドル | 月額3.97ドル |
| 2年間 | $3 /月 | ❌ 提供されていません |
| 返金保証 | 30日間 | 30日間 |
VyprVPN: The 2-year plan at $3/month is the cheapest option here. The $5 monthly plan also costs less than half of StrongVPN’s monthly rate. Some sites quote $60 a year, which undercuts many rivals. Still, プライベートインターネットアクセス sells three years for $79.
強力なVPN: The annual plan edges out VyprVPN’s 1-year price by a few cents. The monthly plan is steep, though. You do get 250GB of SugarSync cloud storage thrown in.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| 最低価格 | ヴィプVPN | $3/month on the 2-Year plan |
| Restrictive country | ヴィプVPN | Chameleon beats VPN blocks |
| 検証済みのプライバシー | ヴィプVPN | 2018 independent no-logs audit |
| 多くのデバイス | 強力なVPN | 12 connections vs 10 |
| Cloud backup | 強力なVPN | SugarSync 250GB付属 |
| Smart TV streaming | 強力なVPN | Smart DNS support |
💰 あなたの予算
VyprVPN is cheaper on both the 2-year and monthly plans. StrongVPN only wins if you’ll use the free cloud storage.
🔌お使いのデバイス
StrongVPN’s 12 connections suit homes full of Android devices, iPhone, and TVs. A Windows laptop, two phones, and a TV fit easily on either plan. VyprVPN’s 10 is enough for most couples or small families.
🌍 Where You Live
In countries that block VPNs, VyprVPN’s Chameleon protocol is the safer bet. Elsewhere, either is a strong VPN for everyday browsing.
🎓 あなたの経験レベル
Both apps are easy for beginners. VyprVPN’s auto-connect on public WiFi means less to remember.
🆓 無料トライアルとデモ
Neither offers a free plan. Use each 30-day refund window to test speeds and streaming before you commit.
🛟 サポートオプション
StrongVPN offers live chat, phone, and email. VyprVPN has 24/7 customer support, but reviews are mixed. Its Trustpilot score sits at 3.2.

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 individual users and small households. We didn’t test router firmware setups or gaming ping across regions. We also skipped VyprVPN’s 仕事 plans. Those list multiple user management, global 仕事 servers, and an own dedicated server option. Our notes reflect the September 2026 versions, so features may change.

最適な用途: Privacy-focused users, travelers in restrictive countries, budget buyers
VyprVPN is the more trustworthy service of the two. It owns its hardware, runs its own DNS, and has passed an outside audit. The dated audit and US owner are real concerns. Keep an eye on future updates.
StrongVPN is a good VPN for large households. It suits anyone who wants 12 connections and free cloud storage. It also holds up better on speed and streaming.
Neither matches the best VPNs on audits or server count. For most people, though, VyprVPN gives more privacy for less money.

よくある質問
VyprVPNは安全に使用できますか？
Yes, for most people. It owns its servers, runs zero-knowledge DNS, and passed a 2018 no-logs audit. The main concerns are its new US ownership and no recent audit.
VyprVPNの所有者は誰ですか？
Certida, a US company based in Austin, Texas, bought it in 2023. Swiss-based Golden Frog ran it before. The change brought a more generic privacy policy.
StrongVPNは無料ですか？
No. There’s no free version or free trial. You can use the 30-day money-back guarantee to try it without risk.
StrongVPNには何台のデバイスを接続できますか？
You can connect up to 12 devices at the same time on one subscription. That covers phones, laptops, routers, and TVs for most homes.
VyprVPNはゲームに適していますか？
It works for casual play but isn’t ideal. Speeds can drop 38% on nearby servers. Use WireGuard and the closest server to keep ping low.
