⚡ 簡単な評価:
- 価格: モジラ VPN costs $4.99/month (annual) or $9.99/month (monthly). OpenVPN has a $0 Free plan and a $7/month Growth plan.
- 最適な用途: モジラ VPN suits Firefox users who want one-click privacy. OpenVPN suits IT teams that need remote access and control.
- 主な違い: Mozilla VPN is a finished app that runs only on WireGuard. OpenVPN is an open-source protocol plus 仕事 software you configure.
- 私たちのおすすめ: OpenVPN wins overall. It starts free and bends to almost any network.

Here’s a surprise: Mozilla VPN doesn’t use OpenVPN at all.
It runs only on the WireGuard protocol.
That tells you these two aren’t the same kind of product.
Mozilla VPN is a standalone VPN you install and switch on.
OpenVPN is an open-source tunneling protocol with business software around it.
So the right pick depends on what you need to protect.

OpenVPN とは何ですか?
OpenVPN is an open source VPN protocol first created in 2001.
It builds a secure tunnel between a VPN client and a VPN server.
Secure Sockets Layer and TLS handle the handshake that opens that tunnel.
Data then travels over UDP for speed or TCP for reliability.
The OpenVPN company, once called OpenVPN Technologies, also sells business tools.
These include OpenVPN Access Server and a cloud service called CloudConnexa.
Most VPN providers also build OpenVPN software into their own apps.

This video shows how an Access Server setup comes together.

オープンVPN
Open-source security with full control over your own servers. Start free with three connections.
OpenVPNの価格設定
OpenVPN prices its business products by plan. The core protocol stays free.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 無料 | $0 | Testing or tiny teams (three connections) |
| 成長 | 月額7ドル | Small and growing teams |
| 企業 | カスタム | コンプライアンス要件のある大企業 |
Pricing verified September 2026.

無料トライアル: No trial needed. The Free plan gives you three connections to test with.
返金保証: OpenVPN doesn’t advertise one. Read the billing terms before signing a yearly contract.
📌 注記: The OpenVPN Community Edition is separate and costs nothing. Yearly contracts on the cloud plans come with a 20% discount.
⚠️ Price check: Some listings show the Growth plan billed per seat. Monthly terms can cost more. Confirm your real per-connection cost at checkout.
OpenVPNの主な利点
Here’s why IT teams keep choosing OpenVPN:
- Open to Inspection: The open source OpenVPN protocol lets anyone read and test the code. Community scrutiny leads to fast fixes.
- Flexible Encryption: It supports AES, Blowfish, and more through the OpenSSL library. You choose the ciphers, key lengths, and encryption protocols.
- 完全な前方秘匿性: Fresh keys protect each session. One stolen key won’t expose all your past traffic.
- Firewall-Friendly: It crosses firewalls and NAT gateways that trip up other protocols. That helps on strict ホテル or office networks.
- IPv4 and IPv6 Ready: It handles both address types. That keeps modern network setups simple.
- あなたに合わせて拡張可能: It works for one remote worker or a web of offices. Site-to-site links use the same core tech.

機能比較
Let’s put Mozilla VPN and OpenVPN side by side. We’ll cover eight areas that matter most when you choose.
| 特徴 | モジラVPN | オープンVPN |
|---|---|---|
| 開始価格 | 月額4.99ドル(年間契約) | 0ドル(無料プラン) |
| 無料プラン | ❌ | ✅ |
| One-Click Consumer App | ✅ | ❌ |
| WireGuardプロトコル | ✅ | ❌ |
| TCP & UDP Modes | ❌ | ✅ |
| キルスイッチはデフォルトでオンになっています | ✅ | ❌ |
| スプリットトンネリング | ✅(アプリ除外) | ✅ (route-based) |
| セルフホスト型サーバー | ❌ | ✅ |
| Firefox Integration | ✅ | ❌ |
| 最適な用途 | Private everyday browsing | ビジネス向けリモートアクセス |
1. Setup & Ease of Use
モジラVPN: Mozilla VPN is built for one-click use. You sign in, pick from the server list, and connect. The Android app and iOS app look almost identical, so there’s no learning curve.

オープンVPN: OpenVPN asks more of you. You install OpenVPN on a server and create user profiles. Then you load .ovpn files into a client like OpenVPN Connect. Windows users can also use the OpenVPN GUI. Profiles from any OpenVPN compatible service import the same way.

💡 プロのヒント: Want OpenVPN without manual configuration? Many VPN services ship it preconfigured. ExpressVPN, Surfshark, and サイバーゴースト all offer it as a protocol option. ExpressVPN gets recommended most for its preset OpenVPN and high speeds.
2. セキュリティと暗号化
モジラVPN: Mozilla VPN uses the WireGuard protocol exclusively. The kill switch is on by default, and Cure53 audits back up its privacy claims. It also blocks ads, trackers, and malware. DNS requests stay inside the tunnel, and reviewers report no DNS leaks.

オープンVPN: OpenVPN uses the OpenSSL library for SSL/TLS and supports many encryption algorithms. A hash message authentication code checks each packet. Turn on TLS auth and it acts as an HMAC firewall. Unsigned packets get dropped before they reach your server.

Public key infrastructure manages the certificates and encryption keys. Access Server adds the multi-factor authentication OpenVPN admins often need. Compared with other VPN protocols like PPTP, it’s far safer. Many security reviews rate it above most VPN protocols. プライベートインターネットアクセス even lets you pick your OpenVPN encryption level.
⚠️ 警告: So is OpenVPN safe? Yes, but only as safe as your setup. Weak encryption ciphers or sloppy key handling can undo its strengths.
3. Privacy & Logging
モジラVPN: Mozilla VPN’s privacy policy says it stores no activity logs. It still collects your IP address, some technical details, and limited interaction data. Some reviewers report IP retention of up to 90 days. Read the notice if session times or metadata matter to you.

オープンVPN: Self-host OpenVPN and you control the logs. No outside VPN provider sees your data traffic. Free public OpenVPN servers set their own rules, so vet them first. That matters for teams handling sensitive data.
The cloud product also adds DNS security and content filtering. It blocks known malicious domains before your team reaches them.
4. Speed, Servers & Streaming
モジラVPN: WireGuard gives Mozilla VPN fast speeds on nearby servers. One review saw download speeds peak near 360Mbps. Others rate it below average against other VPNs. Expect some drop in upload speed on distant server locations.
オープンVPN: OpenVPN works over two transport modes. OpenVPN UDP uses the User Datagram Protocol, which is quicker but skips delivery checks. OpenVPN TCP uses the Transmission Control Protocol. It delivers every packet in order, so it’s steadier but slower.
OpenVPN is slower than newer tunneling protocols like WireGuard. It has no consumer server network. Speed depends on where your OpenVPN servers live.
On streaming, Mozilla VPN’s server network covers 500+ servers in 30+ countries. The app is sold in about 35 countries. It can unblock ITV, Channel 4, and 9Now. It struggles with Netflix, Disney Plus, and other services. Don’t count on it for geo restricted content.
💡 プロのヒント: Use the UDP protocol for calls and video. Switch to TCP on networks that block UDP.
5. Firefox & Cloud App Access
モジラVPN: This is Mozilla VPN’s party trick for Firefox users. Multi-Account Containers can send each tab through a different VPN server. You could open Facebook through one country and email through another.

オープンVPN: OpenVPN has no browser add-on. Instead, CloudConnexa routes traffic to SaaS apps through a secure tunnel. Admins can limit app logins to VPN-connected users only.

The same cloud service adds a protection layer across your team’s SaaS tools.
⚠️ Don’t mix these up: Firefox now ships a free built-in VPN with 50GB a month. It only covers the browser. The paid Mozilla VPN protects every app on your device.
6. Split Tunneling & Firewall Bypass
モジラVPN: Mozilla VPN’s split tunneling feature is called app exclusions. Excluded apps use your regular internet connection while everything else stays protected. It works on Windows, Android, and Linux, but not on iOS.

オープンVPN: OpenVPN splits traffic by routes, so only chosen networks use the VPN tunnel. It is also known for slipping past firewalls and NAT gateways. Run it over TCP port 443 and your internet service provider sees normal-looking web traffic. Scripts and plugins let teams build a custom security protocol setup.
7. Devices, Remote Access & Business Use
モジラVPN: Mozilla VPN runs on every major operating system and covers up to five devices. Some reviews call that five-device cap tight for families. It isn’t built for remote access to company networks.

オープンVPN: OpenVPN runs on Windows, macOS, Linux, Android, and iOS. It even supports router firmware like Tomato, plus Solaris. It protects IoT gear and handles IPv4 and IPv6. It’s widely used to give staff internet access and secure connections to company systems. Setup on mobile devices feels clunkier than on desktop, though.

Site-to-site links are where OpenVPN pulls furthest ahead. It links private networks in different offices as if they shared one building. Admins manage all OpenVPN connections from a single dashboard.

8. 価格設定とコスト
Here’s how the plans line up side by side.
| プラン | モジラVPN | オープンVPN |
|---|---|---|
| 無料 | ❌ 無料版はありません | 無料:0ドル |
| エントリー料金プラン | 年間:月額4.99ドル | Growth: $7/month |
| Flexible Billing | 月額:9.99ドル/月 | Growth, monthly or yearly |
| 企業 | ❌ | エンタープライズ:カスタム |
モジラVPN: Reviewers call it affordable next to ExpressVPN and ノードVPN. Still, its annual rate costs more than some rivals’ yearly deals. Mullvad VPN’s monthly price also beats Mozilla’s monthly plan.
オープンVPN: The OpenVPN free tier is real. The Community Edition costs nothing for creating VPN tunnels yourself. Growth scales with your team. Enterprise pricing is quote-based.

私たちのレビューで取り上げられなかったこと
This comparison focused on individual users and small teams. We didn’t test large Access Server rollouts or Enterprise contracts. We also didn’t run our own controlled speed tests across every region. If you manage hundreds of VPN clients with strict compliance rules, your needs may differ.
