OpenVPN là gì?
OpenVPN is an open source tunneling protocol for building a virtual private network.
It first launched in 2001.
It builds a secure tunnel between a VPN client and a VPN server.
That tunnel runs on SSL/TLS, the tech behind secure sockets layer encryption.
OpenVPN works by wrapping each dữ liệu packet in extra encrypted layers.
The OpenVPN company also sells OpenVPN Access Server and cloud plans for businesses.
You can also use it through any OpenVPN compatible service, like Surfshark or ExpressVPN.
In 2026, IT teams still pick it for creating VPN tunnels into private networks.
OpenVPN
Free to start and open source. Built for people who want full control over their VPN tunnels.

1. Bảo mật & Mã hóa
OpenVPN: OpenVPN uses the OpenSSL library for encryption. It supports AES, Blowfish, and other encryption protocols. Admins pick the cipher and key length, and those choices set the final strength.
It runs a custom security protocol built on SSL/TLS. It checks both sides before any data moves. The authentication OpenVPN relies on combines passwords with digital certificates from a public key infrastructure.
FastestVPN: FastestVPN uses AES-256 encryption on every connection. It adds DNS leak protection and a NAT firewall on top. Its malware blocker helps, but it doesn’t replace antivirus software.
⚠️ Cảnh báo: Strong encryption can’t fix a weak setup. A badly configured OpenVPN server can be less safe than a well-run commercial app.
2. VPN Protocols: TCP, UDP, and WireGuard
OpenVPN: OpenVPN runs over two transport modes. UDP, the user datagram protocol, is faster but doesn’t guarantee delivery. TCP, the transmission control protocol, delivers packets in order but runs slower.
OpenVPN UDP suits streaming and calls. OpenVPN TCP suits shaky or filtered networks. It’s slower than WireGuard, a newer rival among tunneling protocols. Some security writers still prefer OpenVPN for its flexibility.
Security guides rate it above most VPN protocols, including old PPTP. Most VPN providers support it too. A TLS auth key adds an HMAC firewall. It uses a hash message authentication code to drop unsigned packets.
FastestVPN: FastestVPN lets you pick the WireGuard protocol, OpenVPN, and other VPN protocols. Pick OpenVPN TCP on strict networks. Pick WireGuard when speed matters most.
💡 Mẹo hay: Try the UDP protocol first. Switch to TCP only if your connection keeps dropping.
3. Remote Access & Business Networking
OpenVPN: This is where OpenVPN shines. OpenVPN Access Server lets remote workers reach company files safely. It scales from one employee to full office-to-office links.
Site-to-site networking connects whole offices through one encrypted link.
FastestVPN: FastestVPN is built for personal privacy, not company networks. It has no remote access gateway or site-to-site tools. Businesses should look elsewhere.
4. Device Compatibility & Setup
OpenVPN: OpenVPN runs on all major operating systems, plus Tomato and Solaris. It can also secure IoT devices like cameras and sensors. To install OpenVPN on Windows, you use the OpenVPN GUI or OpenVPN Connect.
OpenVPN Connect is free client software. Many other VPN clients can also read .ovpn files.
FastestVPN: FastestVPN’s apps cover Windows, Mac, Android, iOS, and Linux. You install FastestVPN, log in, and tap connect. Devices like Apple TV may need a router setup.
The Windows app and the FastestVPN iOS app share one clean layout. Android users get the same streaming tab and kill switch.
5. Leak Protection & Kill Switch
OpenVPN: OpenVPN’s cloud DNS security can block bad domains before they load. On personal OpenVPN connections, leak protection depends on your client settings. You control how DNS requests leave the tunnel.
FastestVPN: FastestVPN includes a kill switch that cuts your internet if the VPN connection drops. DNS leak protection sends DNS queries through its own servers.
The kill switch is your backup if the tunnel fails. It stops data leaks before they happen.
⚠️ Cảnh báo: Reviewers who tested FastestVPN on a Windows computer found DNS leaks and exposed IP addresses. Others questioned how well the kill switch works. Run your own DNS leak tests after setup.
6. Split Tunneling & App Access
OpenVPN: OpenVPN’s cloud plans can lock down access to SaaS apps. Admins decide who reaches which cloud tool. Split tunneling lives in the config file, not behind a simple toggle.
SaaS protection also shows who touches each cloud app.
FastestVPN: Smart tunneling is FastestVPN’s name for split tunneling. You choose which apps use the VPN tunnel. Its browser extensions only cover browser traffic, not your whole device.
7. Kết nối đồng thời
OpenVPN: Self-hosted OpenVPN has no fixed cap on VPN connections. Your server hardware sets the real limit. Paid plans are priced for việc kinh doanh teams instead.
FastestVPN: One account supports up to 10 simultaneous device connections. You can buy extra slots as an add-on.
8. Speed & Streaming
OpenVPN: Speed depends on your OpenVPN servers, your base internet, and TCP versus UDP. On its own, it can’t unblock streaming sites. You’d need servers in other countries.
FastestVPN: Reviewers testing FastestVPN found downloads drop about 45% on average. One test hit around 730 Mbps on a nearby server using WireGuard. Long-distance servers lost up to 55% of their speed.
Upload speeds slowed about 22% in one test. Ping rose 33% on one of two computers. A slow base connection means slow VPN speeds too.
With so few servers, peak times can crowd FastestVPN’s servers and cause slow speeds. Torrenting works on all FastestVPN servers, but it’s not quick.
Is streaming FastestVPN’s strong suit? Mostly. It works with streaming services like Netflix, Disney+, BBC iPlayer, Hotstar, Prime Video, and Hulu. Its streaming servers unblocked US, UK, Japan, and Sweden Netflix libraries.
⚠️ Cảnh báo: The name suggests the fastest VPN, but FastestVPN claims don’t match independent tests. The US Netflix library loaded slowly, and the Australian library didn’t work.
9. Hỗ trợ khách hàng
OpenVPN: OpenVPN offers documentation, community forums, and ticket support on việc kinh doanh plans. G2 reviews of OpenVPN Access Server often praise its technical support.
FastestVPN: FastestVPN offers 24/7 live chat with real people, plus email support. Replies come fast but can feel generic. The knowledge base has setup guides, though its search is weak.
✅ Good sign: Positive Trustpilot reviews often mention FastestVPN’s customer support by name. Still, some users found support unhelpful on tricky issues.
10. Định giá & Chi phí
Here are the plans side by side.
| Loại kế hoạch | OpenVPN | VPN nhanh nhất |
|---|---|---|
| Miễn phí | Miễn phí: $0 | ❌ |
| Hàng tháng | Growth: $7/month | 1 Month Plan: $5/mo |
| Giá trị tốt nhất | — | 1 Year + 1 Year Free: $0.83/mo |
| One-Time | ❌ | Exclusive Lifetime Plan: $40 |
| Việc kinh doanh | Doanh nghiệp: Tùy chỉnh | ❌ |
OpenVPN: The free tier is real, but running it isn’t free. You still pay for a VPN server, cloud hosting, or hardware. Growth suits small teams that want managed access.
FastestVPN: FastestVPN is the cheaper path for one person who wants servers ready to go. The lifetime plan beats years of monthly billing. Watch add-on costs like dedicated IPs.
Các kịch bản khác nhau

Những điều mà bài đánh giá của chúng tôi chưa đề cập
This comparison focused on home users and small teams. We didn’t run OpenVPN Access Server at enterprise scale. We also didn’t review port forwarding or double VPN servers. Nor did we check which server locations are virtual servers.
We didn’t check every Netflix library FastestVPN supports. Our notes reflect the September 2026 versions of both tools. Features may change after that.
We also skipped FastestPass, the company’s separate trình quản lý mật khẩu. Our full Đánh giá FastestVPN goes deeper on apps and speed.
