OpenVPN là gì?
A virtual private network hides your traffic inside an encrypted tunnel.
OpenVPN is an open source VPN protocol first released in 2001.
It builds a secure tunnel between a VPN client and a VPN server.
The OpenVPN software creates secure connections for VPN clients on almost any device.
That tunnel uses SSL/TLS, the same family as the secure sockets layer.
OpenVPN is one protocol, but it is also a company with paid products.
The OpenVPN company (OpenVPN Technologies) sells Access Server and a cloud service.
Businesses use it for remote access to company private networks.
Here’s a quick video walkthrough of how it all fits together.

So sánh tính năng
Both tools build virtual private networks, but they split hard on almost everything else. We’ll walk through nine features, then compare prices.

| Tốt nhất cho | Teams and tech-savvy users | Người mới bắt đầu với ngân sách hạn chế |
1. Tunneling Protocols
OpenVPN: Here’s how OpenVPN works. It is the tunneling protocol itself. It can run over the user datagram protocol for speed. Or it can use the transmission control protocol for reliability. TCP makes sure every packet arrives in order, and the UDP protocol skips that check.
OysterVPN: OysterVPN lets you switch between WireGuard, OpenVPN, and IKEv2. That mix covers the main VPN protocols most people need. The app handles VPN connections without any config file.
⚠️ Cảnh báo: Some older reviews say OysterVPN lacks WireGuard. Update the app and check the protocol menu yourself.
2. Encryption & Authentication
OpenVPN: OpenVPN pulls encryption algorithms like AES and Blowfish from the OpenSSL library. Before data moves, a two-way authentication OpenVPN runs checks both sides. Each side shows certificates from a public key infrastructure. A hash message authentication code (HMAC) signs each packet. The TLS auth HMAC firewall then drops anything unsigned.
OysterVPN: OysterVPN uses AES-256 across its apps. You never touch encryption keys, encryption protocols, or certificates. The app handles every handshake for you.
3. Privacy & Logging
OpenVPN: With self-hosted OpenVPN servers, you decide what gets logged. On the business side, logging is a feature. Admins want to see who opened which cloud app. Perfect Forward Secrecy means one leaked key can’t unlock past sessions.
OysterVPN: OysterVPN promises a zero logging policy. It says it doesn’t collect or store your browsing data. But no independent firm has checked that claim.
💡 Mẹo hay: A logs policy is only a promise until someone audits it. If you need an audited no logs policy, OysterVPN doesn’t have one yet.
4. Công tắc ngắt khẩn cấp & Bảo vệ chống rò rỉ
OpenVPN: OpenVPN itself doesn’t ship a one-click kill switch. You set up leak blocking through firewall rules or your OpenVPN client settings. That works, but it takes know-how.
OysterVPN: OysterVPN includes an internet kill switch. If the VPN connection drops, it cuts your internet connection so nothing slips out. That prevents accidental data leaks on shaky Wi-Fi. It’s a crucial feature for torrenting.
OysterVPN also adds IP leak protection and DNS leak protection. Your DNS requests stay inside the tunnel, not with your internet service provider.
5. DNS Filtering & Ad Blocking
OpenVPN: OpenVPN’s business products include DNS security and content filtering. They block bad domains before anyone on your team loads them. It’s built for company policy, not for hiding YouTube quảng cáo.
OysterVPN: OysterVPN has a built-in ad and malware blocker. You switch it on inside the app. It cleans up pages on news and streaming sites.
6. Remote Access & Network Defense
OpenVPN: This is where OpenVPN shines. The OpenVPN Access Server links remote staff to office networks. Site-to-site setups join whole branch offices, and admins manage all OpenVPN connections from one panel. Creating VPN tunnels between locations is a core use case.
OysterVPN: OysterVPN isn’t made for company networks. Its defense focus is on you. DDoS protection shields your connection from flood attacks. That’s handy for gamers and streamers.
7. Devices & Connections
OpenVPN: OpenVPN runs on nearly all operating systems and even IoT gadgets. On your own server, you can allow unlimited connections. OpenVPN Connect and the OpenVPN GUI are free client software for your devices.
OysterVPN: OysterVPN covers five simultaneous connections on multiple devices. The OysterVPN apps include desktop apps for Windows and Máy Mac. Its mobile apps cover an Android app and iOS app. There are no browser extensions and no native Linux app. Smart TVs and other streaming devices get no app either.
⚠️ Cảnh báo: OpenVPN on mobile devices is less user-friendly than on desktop. Expect to import .ovpn files by hand.
8. Speed, Servers & Streaming
OpenVPN: OpenVPN has no server network of its own for streaming. Your speed depends on your server hardware and where it sits. It’s also slower than WireGuard, though UDP mode closes some of the gap.
OysterVPN: Server counts differ by source. Some list 150+ servers in 17 countries, others 400+ in 35+ countries. Either way, you get fewer server locations than big-name rivals. Connection speeds are decent on nearby servers. But OysterVPN’s speeds drop about 55% on distant servers.
On streaming, OysterVPN unblocks popular streaming services like Netflix, Max, and ESPN+. It struggles with Hulu, Disney+, and 4K video. Need dedicated streaming servers for those? Look elsewhere. On the plus side, OysterVPN’s servers all allow torrenting.
💡 Mẹo hay: Run a speed test on the fastest server near your physical location. Compare download speed and upload speed before and after you connect.
9. Split Tunneling & App Control
OpenVPN: OpenVPN controls traffic with routing rules in the config file. On the business plans, you can give staff secure access to specific SaaS apps only. It’s flexible, but not point-and-click.
OysterVPN: The split tunneling feature lets you pick which apps use the VPN tunnel. Your banking app can skip it while streaming stays protected. It’s only on the Windows and Android apps for now.
10. Định giá & Chi phí
Here are both price lists side by side.
| Cấp độ | OpenVPN | OysterVPN |
|---|---|---|
| Miễn phí | Miễn phí: $0 | ❌ |
| Lối vào | Growth: $7/month | 1-Month +2 Months free: $5.99/month |
| Longer term | — | 1-Year: $29.99/month |
| Hạng cao nhất | Doanh nghiệp: Tùy chỉnh | Lifetime Access: $59.99/month |
OpenVPN: You can run OpenVPN for $0 if you host it yourself. The paid tiers make sense once a team needs hosted servers and admin tools.
OysterVPN: You pay for a finished service with servers included. The lifetime access deal is the standout if you plan to keep it for years.

🏆 WINNER: OPENVPN

OpenVPN takes this one on security, transparency, and cost. It remains a preferred choice in 2026 for its mix of security, flexibility, and compatibility.
Security experts often list it among the safest VPN protocols. It also offers better security than most VPN protocols. Compared with other VPN protocols like PPTP, it’s far stronger. WireGuard still beats it on speed.
OysterVPN earns its spot for a different crowd. It’s a decent VPN for casual VPN users who want one-tap streaming. It just needs an audit and a bigger network to compete with the big names.
Here’s the simple rule. If you’d rather build, pick OpenVPN. If you’d rather buy, pick OysterVPN.
