機能比較
Let’s compare ProtonVPN vs Mozilla VPN across nine key areas.
This breakdown covers everything from security features to pricing and ease of use.
| 特徴 | プロトンVPN | モジラVPN |
|---|---|---|
| 開始価格 | 月額0ドル（無料） | 月額4.99ドル |
| 無料プラン | ✅ | ❌ |
| サーバー数 | 8,600+ | 500+ |
| 国々 | 112 | 30+ |
| 同時デバイス | 10 | 5 |
| キルスイッチ | ✅ | ✅ |
| スプリットトンネリング | ✅ | ✅（Androidのみ） |
| ストリーミングのブロック解除 | ✅ (Netflix, BBC iPlayer) | ❌（数量限定） |
| オープンソースアプリ | ✅ | ❌ |
| 最適な用途 | Privacy, streaming, free VPN | Simple browsing, Firefox users |
1. サーバーネットワーク
プロトンVPN: Proton VPN runs over 8,600 VPN servers spread across 112 countries. This massive server network means you’ll find a nearby server almost anywhere in the world. More server locations also help you unblock geo-restricted content from more regions.
モジラVPN: Mozilla VPN has around 500+ servers in 30+ countries. The network is powered by Mullvad VPN’s infrastructure. While the server list is much smaller, Mullvad’s servers are known for strong privacy protections and decent speed.
2. プライバシーとセキュリティ
プロトンVPN: Based in Switzerland under some of the world’s strongest privacy laws, Proton VPN keeps no IP logs or activity records. All Proton apps are open-source, and the service has passed independent third-party audits. It uses AES-256 encryption with Perfect Forward Secrecy to create a secure VPN encrypted tunnel.
モジラVPN: Mozilla VPN does not log your online activity. However, it collects your IP address and keeps it for up to 90 days after signup. Mozilla is based in the US, which is part of the Five Eyes surveillance alliance. The service has been audited by Cure53. It handles all dns requests through secure servers.
⚠️ 警告： Mozilla VPN’s 90-day IP address retention is a notable privacy concern. If strict anonymity matters to you, Proton VPN’s no-logs approach is the safer bet.
3. VPNプロトコル
プロトンVPN: Supports multiple VPN protocols including オープンVPN, IKEv2, and WireGuard. It also has a proprietary Stealth protocol designed to bypass internet censorship by making VPN traffic look like regular internet traffic.
モジラVPN: Uses the WireGuard protocol exclusively. WireGuard is fast and secure, but having only one option means you can’t switch to OpenVPN if WireGuard is blocked on your network.
4. 速度とパフォーマンス
プロトンVPN: Features a VPN Accelerator that uses advanced networking techniques to boost connection speeds. According to published specs, it can reach high download speeds on nearby servers. The large server network helps reduce congestion.
モジラVPN: WireGuard provides solid baseline speeds. Download speeds have been reported around 360Mbps during independent tests. Upload speed performance is also decent. However, some reviewers note that Mozilla VPN’s download speed is below average compared to other VPNs.
5. ストリーミングとブロック解除
プロトンVPN: Can unblock Netflix, BBC iPlayer, and Amazon Prime Video. It supports streaming from popular services and has dedicated servers for this purpose. It’s a strong choice if you want to watch geo restricted content.
モジラVPN: Struggles with major streaming services. It can unblock ITV, Channel 4, and 9Now, but fails with Netflix and Disney Plus. If streaming is your main reason for a VPN, Mozilla VPN is not the right pick.
6. スプリットトンネリング
プロトンVPN: Offers split tunneling on all major platforms. This lets you choose which apps use the encrypted VPN tunnel and which connect through your regular internet connection. Handy for banking apps or local services.
モジラVPN: Mozilla offers a split tunneling feature called “app exclusions.” You can pick specific apps that bypass the VPN connection. However, this split tunneling feature is only available on the Android app — not on the iOS app or Windows.
7. デバイスサポート
プロトンVPN: Supports up to 10 devices on one account. The Proton VPN app works on Windows, Mac, iOS, Android, Linux, Android TV, and Apple TV. This covers nearly every mobile device and operating system you might use. Any Linux user will appreciate the dedicated Linux app.
モジラVPN: Supports up to five devices per subscription. Available on Windows, Mac, iOS, Android, and Linux. No smart TV apps. Five devices should be enough for most individuals, but families may find it limiting.
8. 高度なセキュリティ機能
プロトンVPN: Includes Secure Core servers that route traffic through privacy-friendly countries first. Also offers NetShield for blocking access to ads and malware, DNS leak protection, a kill switch, Tor over VPN access to the Tor network, and port forwarding. These security features set it apart from other VPN services.
モジラVPN: Offers multi hop connections that route traffic through two servers for added security. Includes a kill switch enabled by default, DNS leak protection, and ad/tracker blocking. No Tor support or port forwarding. Mozilla VPN’s feature list is smaller than what other VPN providers offer.
9. 価格とコスト

| 毎月 | 月額9.99ドル | 月額9.99ドル |
| プレミアムバンドル | 月額7.99ドル（無制限） | ❌ 利用できません |
プロトンVPN: Offers a permanently free plan with no data limits. The paid Plus plan at $2.99/month (2-year) is $2/month cheaper than Mozilla VPN’s annual plan. You also get double the device connections and 17x more servers.
モジラVPN: Costs $4.99/month on an annual subscription or $9.99/month paid monthly. No free tier is available. The pricing is simple, but you get fewer features and fewer servers for a higher price compared to Proton VPN.

🔒 あなたのプライバシーのニーズ
For journalists, activists, or anyone needing strict anonymity, Proton VPN’s Swiss jurisdiction and Tor over VPN are hard to beat.

What Our Review Didn’t Cover
This comparison focused on individual users and small households. We didn’t test enterprise-level deployments or evaluate router-level VPN setups. Custom DNS configurations and detailed latency measurements across all server locations were outside our scope.
