So sánh tính năng
Now let’s put OpenVPN vs Virtual Shield side by side. We’ll walk through ten areas that matter most to VPN users.
| Tính năng | OpenVPN | Lá chắn ảo |
|---|---|---|
| Giá khởi điểm | $0 (Growth $7/month) | 9,58 đô la/tháng |
| Gói miễn phí | ✅ | ❌ |
| Built-in VPN Servers | ❌ | ✅ |
| Open Source Code | ✅ | ❌ |
| TCP and UDP Choice | ✅ | ✅ |
| phần mềm diệt virus | ❌ | ✅ |
| Giám sát Mạng Tối | ❌ | ✅ |
| Kết nối giữa các địa điểm | ✅ | ❌ |
| Chia đường hầm | ✅ (via config) | ❌ |
| Tốt nhất cho | Tech teams and DIY users | Families wanting simple protection |
1. VPN Connection and Remote Access
OpenVPN: 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.
Lá chắn ảo: 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
OpenVPN: 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.
Lá chắn ảo: 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.
⚠️ Cảnh báo: 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. Tốc độ và hiệu năng
OpenVPN: 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.
Lá chắn ảo: 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.
💡 Mẹo hay: Streaming or gaming? Pick UDP. On shaky khách sạn Wi-Fi, switch to TCP to stay VPN connected.
4. Antivirus and Malware Defense
OpenVPN: OpenVPN has no antivirus at all. Its sole purpose is securing data in transit, not files on your disk.
Lá chắn ảo: 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
OpenVPN: 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.
Lá chắn ảo: 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
OpenVPN: 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.
Lá chắn ảo: Virtual Shield routes traffic through servers that strip intrusive adware. It also blocks known harmful websites on every device.
7. Streaming and Server Locations
OpenVPN: OpenVPN servers are whatever you or your provider run. Most VPN providers support it, so streaming depends on their servers, not the protocol.
Lá chắn ảo: 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.
⚠️ Cảnh báo: 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
OpenVPN: 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.
Lá chắn ảo: 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
OpenVPN: Manual configuration is the biggest hurdle. You edit .ovpn chữ 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.
Lá chắn ảo: 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. Giá cả và chi phí
Here are both price lists side by side.
| Cấp độ | OpenVPN | Lá chắn ảo |
|---|---|---|
| Miễn phí | Miễn phí: $0 | ❌ |
| Lối vào | Growth: $7/month | Basic: $9.58/mo |
| Ở giữa | — | Plus: $13.75/mo |
| Đứng đầu | Doanh nghiệp: Tùy chỉnh | Ultimate: $20.41/mo |
OpenVPN: 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.
Lá chắn ảo: 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.
