OpenVPN là gì?
OpenVPN is an open source VPN protocol first released in 2001.
It builds a secure tunnel between a VPN client and a VPN server.
It runs a custom security protocol on top of SSL/TLS.
That places it in the Secure Sockets Layer family of VPNs.
The OpenVPN company (OpenVPN Technologies Inc.) sells OpenVPN Access Server for việc kinh doanh các đội.
Most VPN providers, like Surfshark and ExpressVPN, run OpenVPN servers too.
So you can use it two ways: self-hosted, or through a VPN provider.
Like other virtual private networks, it shields sensitive data on public Wi-Fi.
Here’s how OpenVPN works in practice.
OpenVPN
Build your own VPN with open source code anyone can inspect. Great for IT teams who want full control.

Tailscale là gì?
Tailscale là một mạng VPN dạng lưới không tin cậy (zero-trust mesh VPN) được xây dựng trên giao thức WireGuard.
It links your own devices into a private network called a “tailnet.”
Once installed, each device gets a stable 100.x.y.z IP address.
Devices talk to other devices directly, not through a central VPN server.
Tailscale’s servers only swap keys and help devices find each other.
That split keeps your network traffic off its servers.
Basically, it’s secure networking without the usual server headaches.
Cân đuôi
Connect laptops, phones, and servers without port forwarding. The free plan covers up to 100 devices.

Pricing verified September 2026.
Dùng thử miễn phí: Sign up with a custom-owned domain, and you get a 14-day Enterprise trial.
Đảm bảo hoàn tiền: Check Tailscale’s billing terms before upgrading. The free plan doubles as your trial.
📌 Ghi chú: The free plan allows three users and up to 100 devices. It can even restrict individual users from specific resources.
⚠️ Price check: Tailscale also sells team plans. Some sites list Starter at $6 per user and Premium at $18 per user. Confirm current rates at checkout.
Lợi ích chính của việc thu gom rác thải quy mô lớn
Dưới đây là những lý do khiến Tailscale đáng để bạn cân nhắc:
- Thiết lập nhanh: Install Tailscale, sign in with an existing account, and the device joins. No router tweaks needed.
- Kết nối trực tiếp: It uses UDP hole punching and NAT traversal to build secure connections. Traffic flows device to device, which cuts lag.
- Truy cập dựa trên danh tính: Access rules follow people, not IP addresses. That’s a big boost for network security.
- MagicDNS: Reach devices by name instead of a long IP address. It’s enabled on new tailnets by default.
- Các nút thoát: Route internet traffic through a device you trust. That’s how Tailscale acts like a classic VPN.
- Không có điểm lỗi duy nhất: The design eliminates single points of failure. Traffic reroutes if one path drops.

1. Truy cập từ xa an toàn
OpenVPN: OpenVPN is widely used for remote access to company networks. Each worker runs an OpenVPN client that dials a central server. It scales from one laptop to large site-to-site links.
Vảy đuôi: Tailscale lets you reach your devices from any network. A laptop at a café can open a home computer as if it’s local. No VPN server sits in the middle.
2. Cài đặt & Dễ sử dụng
OpenVPN: To install OpenVPN yourself, you build a server, certificates, and client profiles. Settings live in editable .ovpn chữ files. On Windows, the OpenVPN GUI imports them. Most VPN users prefer a provider with everything preconfigured.
Vảy đuôi: Download the Tailscale app on each device and sign in. New users join through an invite link. A web dashboard controls users, devices, and permissions.
This tutorial shows the full setup process.
⚠️ Cảnh báo: One wrong line in an OpenVPN config can break the tunnel. Beginners should start with a ready-made profile.
3. Protocols & Encryption
Both tools rely on proven encryption protocols for creating VPN tunnels. The difference is how much you control.
OpenVPN: OpenVPN uses a public key infrastructure, so both sides check certificates. For user authentication OpenVPN can add passwords too. You pick encryption ciphers and key lengths, and each choice affects security.
Vảy đuôi: Tailscale uses WireGuard for every link. WireGuard ships a small, fixed set of modern ciphers. There’s nothing to tune, so there’s less to get wrong.
💡 Mẹo hay: Turn on OpenVPN’s TLS auth option. It acts as an HMAC firewall, tagging packets with a hash message authentication code. Fake packets get dropped sớm.
4. Tốc độ & Hiệu năng
OpenVPN: OpenVPN connections run over one of two transport modes. UDP (user datagram protocol) skips delivery checks, so it’s faster. TCP (transmission control protocol) confirms every packet, which is steadier but slower. Either way, it trails newer tunneling protocols like WireGuard.
Vảy đuôi: Classic VPN clients funnel traffic through one hub server. Tailscale sends traffic straight between devices over WireGuard instead. That lowers lag and raises throughput.
✅ Thông tin hữu ích: Many security guides still list OpenVPN with the safest VPN protocols. Its long history and deep feature set earn that trust.
5. Site-to-Site Networking
OpenVPN: OpenVPN can join two offices with a permanent tunnel. You set routing on both ends and keep both servers online. It’s a common way to link private networks.
Vảy đuôi: Tailscale uses subnet routers to join whole networks. One device shares its local subnet, and the tailnet can reach it. Tailscale works across platforms this way, without dedicated hardware.
6. Zero Trust & Access Controls
OpenVPN: OpenVPN’s business plans can enforce zero trust access rules. Admins decide which groups reach which apps. On the self-hosted side, that takes more planning.
Vảy đuôi: Tailscale starts from a zero-trust model. ACLs grant access by identity, and you can build custom groups. SSO works with 20+ identity providers, and external guests join by invite link.
7. Cloud & SaaS Access
OpenVPN: OpenVPN can create secure access to SaaS apps and cloud tools. Its SaaS protection shows who uses which cloud app. Everything else gets blocked.
Vảy đuôi: Tailscale joins servers on AWS, Google Cloud, and on-premises racks into one network. It also supports Kubernetes clusters and multi-cloud setups. The company lists 100+ integrations overall.
8. IoT & Edge Devices
OpenVPN: OpenVPN can protect IoT traffic between sensors, gateways, and servers. It runs on many routers and lightweight systems. Third-party scripts and plugins can extend it further.
Vảy đuôi: The Tailscale client runs on phones, Apple TV, and a MacBook Pro alike. It also handles edge boxes and small Linux boards. Printers and other clients that can’t run the client software join via a subnet router.
9. DNS & Internet Traffic
OpenVPN: OpenVPN’s business tier adds DNS security and content filtering. Bad domains are blocked before anyone loads them. As a full VPN tunnel, it also hides browsing from your internet service provider.
Vảy đuôi: MagicDNS gives every device a readable name. For internet access through a trusted machine, set it as an exit node. Otherwise, your regular browsing never touches Tailscale.
10. Định giá & Chi phí
Here are both price lists side by side.
| Kế hoạch cấp độ | OpenVPN | Cân đuôi |
|---|---|---|
| Miễn phí | Miễn phí: $0 | Personal: $0 Free Forever |
| Vé vào cửa có phí | Growth: $7/month | Gói Personal Plus: 5 đô la/tháng |
| Doanh nghiệp | Doanh nghiệp: Tùy chỉnh | Team plans sold per user |
OpenVPN: The OpenVPN free tier suits small tests, and the Community Edition costs nothing. Growth adds managed access for small teams. Enterprise pricing is custom, so expect a sales call.
Vảy đuôi: Tailscale’s free plan is generous for home users. Personal Plus adds room for more people on one tailnet. Business plans add more devices per user and priority support.
