機能比較

This comparison pits a complete commercial virtual private network product against the core vpn protocol it often uses.

This proton vpn review clarifies the trade-off between the ease of a full vpn service and the control of openvpn software, helping new users secure their network traffic with the right vpn connection.

1. Product Nature and Ease of Use

  • プロトンVPN: A fully developed vpn service and virtual private network with a dedicated proton vpn app designed for simplicity, one-click connection, and split tunneling.
  • オープンVPN: This is a tunneling protocol and openvpn software framework, not a complete consumer product. It requires manual configuration, importing certificate files, and setting up encryption keys for remote access.

2. Infrastructure and Server Types

  • プロトンVPN: Operates a vast network of vpn servers that include specialized secure core servers with proton vpn servers and Tor over VPN vpn servers. It owns and manages this proprietary vpn infrastructure.
  • オープンVPN: Has no inherent server network. It is the software used on a server. Users must use the openvpn community edition to set up their own vpn server or connect to a third-party’s server.

3. Connection Protocols and Ports

  • プロトンVPN: Offers multiple modern protocols including WireGuard, IKEv2, and optimized implementations of openvpn tcp and openvpn udp. It defaults to the faster user datagram protocol (UDP).
  • オープンVPN: Supports two main protocols: openvpn udp (faster, ideal for general traffic) and openvpn tcp (more reliable on restricted networks due to the tcp transmission control protocol).

4. Advanced Security Features

  • プロトンVPN: Includes built-in features like a kill switch, DNS leak protection, and obfuscation. The encrypted vpn tunnel is managed automatically by the proton vpn app.
  • オープンVPN: Security features like a kill switch must be implemented externally, often via third-party scripts or firewall rules, as the tunneling protocol itself provides the encryption, not the full feature set.

5. Privacy Commitment and Audits

  • プロトンVPN: The proton vpn review highlights its strong no logs policy and privacy-friendly Swiss jurisdiction. Proton vpn passed independent security audits to confirm the integrity of its vpn tunnel.
  • オープンVPN: As open-source software, it is inherently transparent and auditable by the community. However, its privacy relies entirely on how the vpn server operator (the user or third party) manages their logs and policies.

6. App Functionality and Ecosystem

  • プロトンVPN: The proton vpn app is available across all major operating systems, including android app and mobile デバイス. It integrates with proton mail and other proton services.
  • オープンVPN: Requires a third-party openvpn software client (or the official OpenVPN Connect app) to run on mobile devices and computers. It offers basic vpn connection capability without additional features.

7. IP Address Management

  • プロトンVPN: Hides the user’s real ip address and assigns a new with access server, temporary ip address from its pool, ensuring multiple users share the ip address for anonymity.
  • オープンVPN: The ip address assigned is determined by the vpn server configuration. If the user sets up their own server, they control the ip address that the network traffic appears to originate from.

8. Performance Optimization

  • プロトンVPN: Utilizes vpn accelerator technology to optimize performance, and its managed vpn servers are specifically tuned for high vpn connection speeds, offering a fast, secure vpn solution.
  • オープンVPN: Performance depends entirely on the vpn server hardware, configuration (TCP/UDP), and the user’s local setup. It provides the protocol framework but no inherent performance boost.

9. Target Audience

  • プロトンVPN: Designed for general vpn providers users, privacy activists, and journalists who need high-security, easy-to-use remote access and a trustworthy vpn service provider.
  • オープンVPN: Primarily used by network administrators, technical vpn providers, and individuals who want full control over their vpn server setup for customized remote access solutions.

VPN を選択する際に注意すべき点は何ですか?

  • ログなしポリシー: Ensure the VPN provider doesn’t store your browsing activity. This is crucial for privacy for internet service provider.
  • Kill switch: This feature cuts your internet connection if the VPN drops, preventing データ leaks.
  • DNS leak protection: Prevents your DNS requests from being exposed to your ISP.
  • Server locations: Based on your needs (e.g., accessing content from specific countries), consider where you need servers.
  • カスタマーサポート: A responsive team can be invaluable if you encounter issues.
  • Free trial or money-back guarantee: You can test the free VPN risk-free before committing.
  • Independent audits: Look for VPNs that undergo third-party audits to verify their security and privacy claims.

最終評決
