OpenVPN là gì?
OpenVPN is an open source VPN protocol first released in 2001.
It builds a secure tunnel that carries dữ liệu traffic between two points.
The name also belongs to OpenVPN Inc., the OpenVPN company once called OpenVPN Technologies.
That company sells OpenVPN software like Access Server and a cloud remote access service.
The free OpenVPN Community Edition lets anyone run their own OpenVPN server.
Most VPN providers still offer it inside their apps.
In 2026, it’s still a go-to pick for online security and flexibility.
The review below shows how OpenVPN works in practice.
🏆 Winner: OpenVPN
Open source security you can inspect yourself. Pick UDP for speed or TCP for reliability. A strong fit for teams that need remote access.

Ad Guard VPN là gì?
AdGuard VPN is a VPN service from the team behind the AdGuard ad blocker.
It hides your real location by sending traffic through a remote server.
That server gives you a different IP address while the app encrypts your traffic.
The network has 800+ servers in 65 locations across 53 countries.
It uses its own proprietary protocol instead of OpenVPN or WireGuard.
AdGuard puts ad and tracker blocking right next to the VPN.
That combo is the main reason people choose it.

1. Tunneling Protocol & Encryption
OpenVPN: The OpenVPN protocol runs a custom security protocol built on SSL/TLS. That’s the secure sockets layer family. It pulls its crypto from the OpenSSL library. The two-way authentication OpenVPN runs relies on a public key infrastructure and certificates. Perfect Forward Secrecy means one leaked key can’t unlock every past session.
VPN AdGuard: The AdGuard VPN protocol is proprietary and uses AES-256 encryption. It makes VPN traffic look like regular HTTPS to slip past censorship. But nobody outside AdGuard has audited it. That raises real transparency questions.
⚠️ Cảnh báo: AdGuard VPN doesn’t support OpenVPN or WireGuard. You can’t switch to a protocol you trust more.
OpenVPN also adds an extra lock called TLS auth. It signs every handshake packet with a hash message authentication code. This HMAC firewall drops fake packets before they touch the server.
That’s why security experts list OpenVPN with the safest VPN protocols. It beats older encryption protocols like PPTP and offers better security than most VPN protocols. Some even prefer the open source OpenVPN protocol over WireGuard for its flexibility. Other VPN protocols may be faster, but few get checked this hard.
2. Tốc độ & Hiệu năng
OpenVPN: OpenVPN UDP uses the user datagram protocol. It skips delivery checks, so it’s faster but less reliable. OpenVPN TCP uses the transmission control protocol, which confirms every packet arrives in order. It’s steadier but slower. Newer tunneling protocols like WireGuard are faster. Still, it handles browsing and video calls fine.
VPN AdGuard: AdGuard VPN’s performance is fine for everyday browsing on nearby servers, with drops around 20%. Long-distance links hurt more. Reviewers who tested AdGuard VPN saw connection speeds drop from 65 to about 10 Mbps. Paid users fare better, with one test averaging 58.73 Mbps. Some users also report connection drops.
⚠️ Cảnh báo: Slow speeds hurt online gaming and data intensive tasks. Run speed tests on a US server first. Check upload speed before you buy AdGuard VPN.
3. Ad & Tracker Blocking
OpenVPN: The protocol itself has no ad blocker. Business plans add DNS filtering, but that targets threats, not pop-up ads. To block ads, you’ll need a separate tool.
VPN AdGuard: This is where AdGuard shines. Can AdGuard VPN block ads on its own? Yes, once you choose its filtering DNS. Blocking ads this way also speeds up page loads on heavy sites.
4. DNS Security & Content Filtering
OpenVPN: OpenVPN’s cloud service filters DNS and blocks malicious domains before they load. Admins set one rule set for the whole team. That keeps sensitive data safer on every device.
VPN AdGuard: You can pick a DNS server that filters ads, trackers, and shady sites. It’s personal filtering, not team-wide policy. Home users win here. IT teams get little control.
5. Remote Access & Zero Trust
OpenVPN: Remote access is OpenVPN’s home turf. Companies use it so staff can reach private networks from anywhere. OpenVPN Access Server adds user rules and zero trust checks on top.
VPN AdGuard: AdGuard connects you to its own VPN servers, not your office network. You can’t reach a private company system through it. It’s built for personal online privacy instead.
Here’s how OpenVPN applies zero trust rules to each user.
6. Site-to-Site & IoT Networking
OpenVPN: OpenVPN links whole offices together by creating VPN tunnels between sites. It also secures IoT gear like sensors and cameras. The same tool scales from one user to large organizations.
VPN AdGuard: There’s no site-to-site option here. It protects individual devices only, up to 10 per plan. That works for families, but it lacks all the features branch offices need.
The IoT side of OpenVPN looks like this.
7. SaaS Access & Protection
OpenVPN: OpenVPN can put SaaS apps behind the VPN connection. It shows who touches which cloud app and blocks the rest. That helps IT teams stop data leaks.
VPN AdGuard: AdGuard doesn’t manage app access. Every site gets the same treatment, apart from your split tunneling list. Think of it as a privacy tool, not an access gate.
And here’s OpenVPN’s SaaS protection view in action.
8. Privacy, Logging & Trust
OpenVPN: Open code means anyone can hunt for backdoors. Privacy depends on who runs the OpenVPN servers: you, your employer, or a VPN provider. Self-host it, and no third party sees your logs. The tunnel also hides your browsing from your internet service provider.
VPN AdGuard: It has a strict no logs policy. It skips IP addresses, browsing history, and connection timestamps. It collects minimal technical data to fix bugs and shares nothing with third parties. Still, no audit has confirmed any of this.
AdGuard offers Temp Mail too, for extra privacy when you sign up for things.
💡 Mẹo hay: Audits matter. Until AdGuard publishes one, treat its privacy promises as unverified security measures.
9. Apps, Devices & Ease of Use
OpenVPN: OpenVPN Connect is the official OpenVPN client. On a Windows PC, the OpenVPN GUI is another option. Connections run from .ovpn chữ files you can edit or load into other VPN clients. You can install OpenVPN on unlimited devices, but manual setup takes skill. It also feels less smooth on mobile devices than on desktops.
VPN AdGuard: AdGuard has easy to use apps for Windows, macOS, Linux, Android, iOS, and Android TV. Browser extensions cover Chrome, Firefox, and Edge. Setup takes minutes, with no config files. The Windows version also supports integrated mode.
10. Định giá & Chi phí
Hãy cùng so sánh hai bản thiết kế này cạnh nhau.
| Kế hoạch | OpenVPN | VPN AdGuard |
|---|---|---|
| Miễn phí | Miễn phí: $0 | Free version (3 GB/month) |
| Đã trả phí vào cửa | Growth: $7/month | 1 Month: $11.99/month |
| 1-Year Term | — | 1 Year: $3.99/month |
| 2-Year Term | — | 2 Years: $2.40/month |
| Doanh nghiệp | Doanh nghiệp: Tùy chỉnh | — |
OpenVPN: It’s cheapest if you can self-host the Community Edition. The Growth plan suits small teams that want everything managed. Bigger companies get custom quotes.
VPN AdGuard: It’s the cheaper consumer VPN over two years. The monthly plan is steep, so commit longer if you’ll stay. Light users can stick with the free tier.
Các kịch bản khác nhau
| Nếu bạn cần… | Chọn | Tại sao |
|---|---|---|
| Remote access for a team | OpenVPN | Access Server and zero trust tools |
| Ads blocked while you duyệt | VPN AdGuard | Built-in DNS ad filtering |
| Full control over settings | OpenVPN | Open code and custom ciphers |
| Easy setup as a beginner | VPN AdGuard | Simple apps, no config files |
| Ready-made streaming servers | VPN AdGuard | Mở khóa Netflix và Disney+ |
| Maximum transparency | OpenVPN | Public code anyone can audit |
💰 Ngân sách của bạn
If you can run a server, OpenVPN costs you nothing but hosting. If you want zero setup, AdGuard’s longer plans are the cheaper path.
🔌 Bộ công nghệ của bạn
OpenVPN plugs into company networks, SaaS tools, and third-party apps, scripts, and plugins. AdGuard VPN fits a personal setup, especially alongside other AdGuard products.
🎮 Your Daily Use
AdGuard unblocks BBC iPlayer and Netflix but struggles with Amazon Prime and Peacock. Some streaming platforms may also buffer. For gaming, OpenVPN over the UDP protocol on a nearby server is the smoother bet.
🎓 Trình độ kinh nghiệm của bạn
Most VPN users will find AdGuard simpler from day one. OpenVPN rewards people who are comfortable with config files and certificates.
✈️ Du lịch and Censorship
AdGuard VPN struggles with China’s Great Firewall, unlike ExpressVPN or NordVPN. OpenVPN gets past firewalls well, but only if your provider’s servers aren’t blocked.
🆓 Dùng thử và bản demo miễn phí
Try OpenVPN’s free tier and AdGuard’s 3 GB plan side by side. Both let you test before spending anything.
🛟 Các tùy chọn hỗ trợ

🏆 WINNER: OPENVPN
OpenVPN wins 5 out of 8 categories.
Phù hợp nhất cho: Remote teams, privacy-minded tech users, custom VPN setups
These two tools solve different problems. OpenVPN is one part transparent protocol, one part business platform for secure connections. AdGuard VPN is a simple consumer VPN with ad blocking baked in.
AdGuard is a fair pick if you want fewer ads and no setup. Next to premium VPNs, though, it falls short. Missing audits, slow long-distance speeds, and no OpenVPN support hold it back.
If you value control, open code, and room to grow, OpenVPN is the better choice. Start on the free tier and upgrade only when your team needs it.
