개요
This OpenVPN vs AdGuard VPN comparison covers 보안, speed, privacy, pricing, and ease of use.
We reviewed documentation, pricing pages, and independent reviews for both tools.
저희 작가들은 각각의 제품을 직접 다루는 데에도 시간을 할애했습니다.
해당 내용은 아래 '우리 팀이 발견한 사항' 섹션에 나와 있습니다.
결론적으로, 여러분은 자신에게 가장 적합한 VPN 서비스를 알게 될 것입니다.
OpenVPN이란 무엇인가요?
OpenVPN is an open source VPN protocol first released in 2001.
It builds a secure tunnel that carries 데이터 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.
OpenVPN 가격
Here’s what OpenVPN costs in 2026. The plans scale with your team.
| 계획 | 가격 | 가장 적합한 대상 |
|---|---|---|
| 무료 | $0 | Testing and small personal setups |
| 성장 | 월 7달러 | Small teams that want managed remote access |
| 기업 | 관습 | Large organizations with strict compliance needs |
Pricing verified September 2026.
무료 체험: Yes. The free tier and the Community Edition let you test with no time limit.
환불 보장: Refund terms vary by product. Check them at checkout before you upgrade.
📌 메모: OpenVPN free really means free if you self-host. You only pay for your own server. The catch: you get just a few server locations, the ones you run. The OpenVPN Connect client software costs nothing too.
⚠️ 경고: Business plans are priced by the number of OpenVPN connections. Costs climb as more VPN connections join your network.
OpenVPN의 주요 이점
OpenVPN을 고려해 볼 만한 이유는 다음과 같습니다.
- 오픈 소스 코드: Anyone can inspect the code for flaws. A global developer community reviews it and ships fixes fast.
- Flexible Encryption: It supports AES, Blowfish, and other encryption algorithms. You pick the encryption ciphers and the length of your encryption keys.
- TCP or UDP Choice: OpenVPN UDP favors speed. OpenVPN TCP favors complete, in-order delivery.
- Firewall Friendly: It passes through firewalls and NAT gateways well. That helps on strict office or 호텔 네트워크.
- 폭넓은 호환성: It runs on most operating systems, from Windows to iOS. It even works on Tomato and Solaris.
- 성장할 여지: It scales from one laptop to full site-to-site networks. It also handles IPv4 and IPv6 traffic.

AdGuard VPN이란 무엇인가요?
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.
Watch our AdGuard VPN review for a quick tour.

기능 비교
Let’s put OpenVPN vs AdGuard VPN side by side. We’ll cover nine key areas, then finish with pricing.
| 특징 | 오픈VPN | AdGuard VPN |
|---|---|---|
| 시작 가격 | $0 (paid from $7/month) | 월 2.40달러 |
| 무료 플랜 | ✅ | ✅ (월 3GB) |
| Open Source Code | ✅ | ❌ |
| TCP & UDP Modes | ✅ | ❌ |
| Ad & Tracker Blocking | ❌ | ✅ |
| 분할 터널링 | ✅ | ✅ |
| 사이트 간 네트워킹 | ✅ | ❌ |
| Third-Party Code Review | ✅ | ❌ |
| 가장 적합한 대상 | Tech users and teams | Beginners who hate ads |
1. Tunneling Protocol & Encryption
오픈VPN: 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.
AdGuard VPN: 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.
⚠️ 경고: 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. 속도 및 성능
오픈VPN: 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.
AdGuard VPN: 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.
⚠️ 경고: 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
오픈VPN: 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.
AdGuard VPN: 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
오픈VPN: 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.
AdGuard VPN: 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
오픈VPN: 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.
AdGuard VPN: 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
오픈VPN: 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.
AdGuard VPN: 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
오픈VPN: 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.
AdGuard VPN: 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
오픈VPN: 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.
AdGuard VPN: 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.
💡 꿀팁: Audits matter. Until AdGuard publishes one, treat its privacy promises as unverified security measures.
9. Apps, Devices & Ease of Use
오픈VPN: OpenVPN Connect is the official OpenVPN client. On a Windows PC, the OpenVPN GUI is another option. Connections run from .ovpn 텍스트 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.
AdGuard VPN: 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. 가격 및 비용
두 계획을 나란히 비교해 봅시다.
| 계획 | 오픈VPN | AdGuard VPN |
|---|---|---|
| 무료 | 무료: 0달러 | Free version (3 GB/month) |
| 입장료 지불됨 | Growth: $7/month | 1 Month: $11.99/month |
| 1-Year Term | — | 1 Year: $3.99/month |
| 2-Year Term | — | 2 Years: $2.40/month |
| 기업 | 기업: 맞춤형 | — |
오픈VPN: 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.
AdGuard VPN: 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.
다양한 시나리오
| 필요하시면 | 선택하다 | 왜 |
|---|---|---|
| Remote access for a team | 오픈VPN | Access Server and zero trust tools |
| Ads blocked while you 먹다 | AdGuard VPN | Built-in DNS ad filtering |
| Full control over settings | 오픈VPN | Open code and custom ciphers |
| Easy setup as a beginner | AdGuard VPN | Simple apps, no config files |
| Ready-made streaming servers | AdGuard VPN | 넷플릭스와 디즈니+ 차단을 해제합니다 |
| Maximum transparency | 오픈VPN | Public code anyone can audit |
💰 예산
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.
🔌 사용 중인 기술 스택
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.
🎓 귀하의 경험 수준
Most VPN users will find AdGuard simpler from day one. OpenVPN rewards people who are comfortable with config files and certificates.
✈️ 여행하다 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.
🆓 무료 체험 및 데모
Try OpenVPN’s free tier and AdGuard’s 3 GB plan side by side. Both let you test before spending anything.
🛟 지원 옵션
AdGuard has no 24/7 live chat. You file through a ticketing system and wait for the support team. OpenVPN offers paid support, while free users lean on community forums.

저희 리뷰에서 다루지 않은 내용
This comparison focused on individual users and small teams. We didn’t run our own speed tests across countries. We also didn’t test OpenVPN at large enterprise scale or AdGuard inside China. Our notes reflect September 2026 versions, so features may change.

🏆 WINNER: OPENVPN
OpenVPN wins 5 out of 8 categories.
다음과 같은 경우에 가장 적합합니다: 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.
