protonvpn安卓下载

ProtonVPN positions itself as a security- and privacy-first VPN built by the same team behind ProtonMail. Headquartered in Switzerland, a country with strong privacy laws, Proton places legal jurisdiction and independence at the center of its privacy guarantees. That foundation is reinforced by a clear no-logs policy and independent security audits of its apps and infrastructure. Core features - Encryption and protocols: ProtonVPN uses modern encryption (AES-256) and supports WireGuard, OpenVPN and IKEv2. WireGuard is the default choice for most users because it offers a good balance of performance and security. - Secure Core (multi-hop): Secure Core routes traffic through multiple privacy-friendly countries (Secure Core servers run in Switzerland and other jurisdictions) before exiting to the public internet, protecting against network-level surveillance and some server compromises. - Tor over VPN: Dedicated Onion over VPN servers let you access .onion sites through the Tor network without running a separate Tor client. - Traffic protection: ProtonVPN offers a kill switch, DNS leak protection, and IPv6 leak prevention to ensure traffic is not exposed if the connection drops. - NetShield: An optional feature that blocks ads, trackers and malware domains at the DNS level, improving privacy and reducing unwanted content. - Cross-platform apps: Native apps are available for Windows, macOS, Linux, Android, iOS and select routers. Apps are open-source and have undergone third-party audits. Usability and performance ProtonVPN aims to balance privacy with usability. The apps are user-friendly, featuring server browsing by country, specialty servers for P2P and streaming, and split tunneling on supported platforms. WireGuard provides competitive speeds, especially on paid plans. The free plan is a strong offering for privacy-conscious users who need basic VPN coverage, but it’s limited in server choices and can be slower during peak use. Privacy and transparency ProtonVPN’s no-logs stance and Swiss jurisdiction are central trust signals. The company publishes transparency reports and has engaged independent security audits for its software. Secure Core architecture and Tor integration add defense-in-depth for higher-risk users. Considerations No VPN is perfect: ProtonVPN’s paid plans are priced competitively but can be costlier than some mainstream alternatives depending on the deal. Server count is smaller than the largest providers, which can affect server selection in some regions. For most users prioritizing privacy and independent oversight, ProtonVPN remains a strong, reputable choice. Conclusion ProtonVPN is best for users who want a privacy-first VPN backed by strong legal protections, modern encryption, and additional privacy layers like Secure Core and Tor integration. Its combination of a free tier, audited open-source apps and privacy-focused features makes it particularly attractive for security-minded individuals.
