最後には、どれがあなたのニーズに合っているかが分かるでしょう。
OpenVPN とは何ですか?
The open source OpenVPN protocol first appeared in 2001.
It is a tunneling protocol for building a virtual private network.
It sends データ traffic through a secure tunnel to a VPN server.
It is a custom security protocol built on Secure Sockets Layer and TLS.
So how does OpenVPN work?
OpenVPN works by wrapping each data packet in extra layers of encryption.
Your internet service provider sees scrambled traffic, not the sites you visit.
That’s why it often appears on lists of the safest VPN protocols.
The OpenVPN company, once called OpenVPN Technologies, also sells 仕事 ツール。
The best known is OpenVPN Access Server, a self-hosted VPN for teams.
Many VPN providers, like ExpressVPN, サーフシャーク, and CyberGhost, offer it inside their apps.
You can also run your own OpenVPN server for リモートアクセス to private networks.
🏆 Winner: OpenVPN
Build private VPN tunnels you fully control. The Community Edition costs nothing. Paid tools add team management.

バーチャルシールドとは何ですか?
Virtual Shield is a US-based online security suite for home users.
It bundles a VPN with antivirus and identity theft protection.
The goal is all around security from one simple app.
Like other virtual private networks, it hides your IP address.
It watches the dark web for your personal details and sends real-time alerts.
It also blocks harmful websites, adware, and malware through special servers.
Under the hood, the VirtualShield VPN uses OpenVPN as its primary protocol.
So in a way, this matchup is a service versus the engine it runs on.

機能比較
Now let’s put OpenVPN vs Virtual Shield side by side. We’ll walk through ten areas that matter most to VPN users.
| 特徴 | オープンVPN | 仮想シールド |
|---|---|---|
| 開始価格 | $0 (Growth $7/month) | 月額9.58ドル |
| 無料プラン | ✅ | ❌ |
| Built-in VPN Servers | ❌ | ✅ |
| Open Source Code | ✅ | ❌ |
| TCP and UDP Choice | ✅ | ✅ |
| ウイルス対策 | ❌ | ✅ |
| ダークウェブモニタリング | ❌ | ✅ |
| サイト間ネットワーク | ✅ | ❌ |
| スプリットトンネリング | ✅ (via config) | ❌ |
| 最適な用途 | Tech teams and DIY users | Families wanting simple protection |
1. VPN Connection and Remote Access
オープンVPN: OpenVPN focuses on creating VPN tunnels between devices and servers you choose. Companies use OpenVPN connections for remote access to office networks. It works with many VPN clients, including OpenVPN Connect. Access Server adds a web portal to manage every user.
仮想シールド: Virtual Shield connects you to its own servers with one tap. After a successful connection, your real IP address stays hidden. The app is basic, especially on macOS.
2. Encryption and Security Protocols
オープンVPN: OpenVPN verifies both sides through a public key infrastructure. Authentication OpenVPN setups mix user logins with digital certificates. HMAC (hash message authentication code) checks via tls auth add an extra layer. This HMAC firewall drops unsigned packets before they reach the server.
仮想シールド: Virtual Shield applies AES 256-bit encryption to all traffic on its servers. Some sources also list ChaCha20 with Poly1305. Its core protocol is OpenVPN, so the tunnel itself is well tested.
⚠️ 警告： Virtual Shield is based in the US, a 5/9/14 Eyes member. Critics also say it shares little about its ownership and business address. For security and privacy, jurisdiction is an important factor.
3. 速度とパフォーマンス
オープンVPN: The UDP protocol, or user datagram protocol, gives fast speeds by skipping delivery checks. TCP, the transmission control protocol, confirms every packet arrives in order. That makes it more reliable but slower. Other VPN protocols like WireGuard beat both modes on raw speed.
仮想シールド: Virtual Shield markets high speed servers and suggests OpenVPN (UDP) for speed. Speed tests show US servers dipping below 50 Mbps. Other testers call it above average for such a small network.
💡 プロのヒント: Streaming or gaming? Pick UDP. On shaky ホテル Wi-Fi, switch to TCP to stay VPN connected.
4. Antivirus and Malware Defense
オープンVPN: OpenVPN has no antivirus at all. Its sole purpose is securing data in transit, not files on your disk.
仮想シールド: Virtual Shield scans offline files and apps for viruses and malware. That’s a real plus for a family laptop.
It also guards against ransomware that locks your files for payment.
5. Identity Protection and Dark Web Monitoring
オープンVPN: OpenVPN doesn’t track your online identity across the web. Its business tools control who can enter a network instead. Zero Trust rules check each user before granting access.
仮想シールド: Virtual Shield monitors the dark web for leaked personal details. You get real-time alerts and resolution help if your info is exposed.
These dark web scans run quietly in the background.
6. Ad-Blocking and Content Filtering
オープンVPN: OpenVPN’s cloud tools offer DNS security and content filtering. They block malicious domains before anyone loads them. That protects a whole team, not just one laptop.
仮想シールド: Virtual Shield routes traffic through servers that strip intrusive adware. It also blocks known harmful websites on every device.
7. Streaming and Server Locations
オープンVPN: OpenVPN servers are whatever you or your provider run. Most VPN providers support it, so streaming depends on their servers, not the protocol.
仮想シールド: Virtual Shield helps you reach Netflix content, Hulu, and Amazon Prime abroad. For other major platforms like BBC iPlayer, check the Unrestricted Streaming add-on first.
⚠️ 警告： Server counts vary by source. Some list 20 servers in 12 countries, others just 11 countries. Either way, that’s far fewer server locations than big-name rivals.
8. Business and Site-to-Site Networking
オープンVPN: OpenVPN scales from one remote worker to site-to-site links for large organizations. It also secures IoT devices and access to SaaS apps.
Its SaaS protection also shows who opens which cloud app.
仮想シールド: Virtual Shield targets home users, not any business. It has no site-to-site links or team admin tools.
9. Ease of Use and Customer Support
オープンVPN: Manual configuration is the biggest hurdle. You edit .ovpn 文章 files and may troubleshoot the OpenVPN GUI on Windows. The client software also feels less smooth on mobile devices than on desktop. Free users rely on guides and forums for help.
仮想シールド: Virtual Shield’s app is simple for beginners. Customer support runs 24/7 through live chat, which earns it extra points. Still, some reviews say the support team can be slow to respond on billing.
10. 価格設定とコスト
Here are both price lists side by side.
| ティア | オープンVPN | 仮想シールド |
|---|---|---|
| 無料 | 無料：0ドル | ❌ |
| エントリ | Growth: $7/month | Basic: $9.58/mo |
| 真ん中 | — | Plus: $13.75/mo |
| トップ | エンタープライズ：カスタム | Ultimate: $20.41/mo |
オープンVPN: The OpenVPN free route costs nothing if you host your own server. You still pay for hosting and your time. Paid plans make sense once a team needs central control.
仮想シールド: Virtual Shield bundles three tools, which softens the price. But reviewers often call it overpriced next to premium VPNs. Paid add-ons push the bill higher fast.

私たちのレビューで取り上げられなかったこと

🏆 WINNER: OPENVPN
OpenVPN wins 4 out of 7 categories.
最適な用途: Self-hosted VPNs, team remote access, custom secure connections
In our not so humble opinion, these two tools serve different people. Among tunneling protocols, OpenVPN powers countless secure connections. Virtual Shield is a finished product built on that same engine.
Virtual Shield is a good pick for families. They get antivirus, identity alerts, and a VPN in one place. In this crazy world of data leaks, that bundle has real appeal. Reviews swing from satisfied customer stories to billing complaints. Its small network and add-on costs also hold it back.
If you’re comfortable with a little setup, OpenVPN is the better choice. It’s free, open, and scales from a laptop to a whole company.
