1. プライバシーとセキュリティ
プロトンVPN: Based in Switzerland under strict no logs policy laws. ProtonVPN passed an independent third-party audit confirming it keeps no activity or IP logs. All Proton apps are open-source, so anyone can inspect the code. The encrypted VPN tunnel uses AES-256 encryption with Perfect Forward Secrecy. You can run a dns leak test to verify there are no dns leaks while connected. ProtonVPN also has tor servers for users who want access to the Tor network.
ミステリウムVPN: Operates a no logs policy by design. Because the network is decentralized, there is no central server to store user data. However, Mysterium has not completed an independent security audit. The decentralized structure means you’re trusting individual node providers with your internet traffic.
2. サーバーネットワーク
プロトンVPN: Runs over 8,600 VPN servers in 112 countries. All servers are owned or leased by Proton Technologies AG. You can pick specific server locations and see real-time load data. The server network includes dedicated servers for P2P torrenting and Tor network access.
ミステリウムVPN: Offers over 7,500 residential IPs across 100+ countries. The global network is powered by a global community of node providers. You connect through real residential IP addresses instead of data center IPs. However, node quality and speed can vary since they depend on individual providers.
3. 速度とパフォーマンス
プロトンVPN: Includes a VPN Accelerator feature that uses advanced networking to boost internet speeds. Proton VPN support staff have confirmed it works best on long-distance connections. The encrypted tunnel supports WireGuard, OpenVPN, and IKEv2 VPN protocols for flexible speed options.
ミステリウムVPN: Uses the WireGuard protocol for fast VPN connections. Speeds depend on which node you connect to. Some nodes run on fast home internet connections. Others may be slower. There is no speed guarantee since the network is community-powered.
⚠️ 警告： Mysterium VPN speeds can drop significantly on some nodes. If consistent internet speeds matter to you, ProtonVPN’s dedicated server network is more reliable.
4. Free Plan and Trial Options
プロトンVPN: Offers a free VPN plan with unlimited bandwidth and no ads. The free version limits you to 1 device and servers in the US, Netherlands, and Japan. It’s one of the best free VPNs on the market. No credit card required to start.
ミステリウムVPN: No free plan available. You get a 7-day money-back guarantee instead. This gives you a short window to test the VPN service before committing. Most other VPN providers offer 30-day refund periods.
5. ストリーミングとコンテンツへのアクセス
プロトンVPN: Proton VPN offers access to Netflix, BBC iPlayer, and Amazon Prime Video on paid plans. The free tier does not guarantee streaming access. Proton VPN servers are optimized for blocking access issues on streaming platforms.
ミステリウムVPN: Residential IPs make it harder for streaming services to detect VPN usage. This is Mysterium’s biggest advantage for streaming fans. Since your IP address looks like a regular home connection, you face fewer blocks. Works with Netflix, Hulu, and BBC iPlayer according to Mysterium’s documentation.
6. デバイスのサポート
プロトンVPN: The Proton VPN app is available on Windows, Mac, iOS, Android, and Linux. Also supports Android TV and Apple TV. The Linux app has a full GUI. Connect up to 10 devices at once on paid plans. Every mobile device and desktop platform is covered.
ミステリウムVPN: Works on Windows, Mac, Android, and iOS. Also has a Chrome browser extension. No Linux app yet, though it’s reportedly in development. The Pro plan lets you connect up to 15 devices at once, which is more than ProtonVPN.
7. 高度なセキュリティ機能
プロトンVPN: Includes Secure Core servers that route your traffic through privacy-friendly countries before reaching the endpoint server. Also offers split tunneling, DNS leak protection, a kill switch, and NetShield ad blocking. Port forwarding is available for torrent users.
ミステリウムVPN: Provides a kill switch and DNS leak protection. The Pro plan adds malware and phishing blocking. No split tunneling or double VPN options. The decentralized structure itself adds a layer of privacy since there is no central point of failure.
8. Anonymity and IP Protection
プロトンVPN: Hides your IP address behind data center IPs. Supports Tor over VPN for extra anonymity through the Tor network. Accepts Bitcoin for anonymous payment. The strict no logs policy means ProtonVPN cannot share your data even if asked.
ミステリウムVPN: Uses residential IP addresses that look like real home connections. You can connect without creating an account. Crypto payments keep your identity hidden. The decentralized VPN model means your online activities pass through independent nodes, not a single VPN company.
9. カスタマーサポート
プロトンVPN: Offers email-based customer support through ProtonVPN’s website. No live chat support is available. Has a detailed knowledge base and community forums. Response times can vary but are usually within 24 hours.
ミステリウムVPN: Provides email support through their support team. Also has a help center for common questions. The support team can be reached at help@mysteriumvpn.com. No live chat or phone support available.
