📌 笔记： The Unlimited plan bundles Proton Mail, Proton Drive, Proton Calendar, and 质子通道 alongside the VPN. These Proton apps work together for complete online privacy. If you already use other VPN services for Proton services, this plan saves you money compared to buying each one separately. Proton Technologies AG manages all these products from Switzerland.
⚠️ 警告： The free plan limits you to servers in five locations and one device at a time. Secure core servers, streaming support, port forwarding, and dedicated servers for P2P are only on paid plans. This premium VPN can be an expensive VPN compared to budget options.
ProtonVPN 的主要优势
以下是Proton VPN值得考虑的原因：
- 瑞士隐私保护： Based in Switzerland, Proton VPN falls outside of Five Eyes, Nine Eyes, and Fourteen Eyes surveillance alliances. Swiss law requires a court order before any data request.
- 经审计的无日志策略： Proton VPN passed a third-party audit confirming it does not store traffic logs, IP logs, or browsing history. The VPN company also publishes a transparency report.
- 开源应用： Every Proton VPN app is open-source. Anyone can inspect the code for security flaws. This level of transparency is rare among other VPN providers.
- 大型服务器网络： Over 8,600 VPN servers spread across 112 countries. The server list is far larger than most VPN companies offer.
- 免费无广告套餐： The free VPN has unlimited bandwidth, no ads, and no speed throttling. Compared to other free VPNs, this free tier is hard to beat.
- 安全核心架构： Routes your internet traffic through an encrypted VPN tunnel in privacy-friendly countries before reaching the endpoint server. This adds an extra layer of protection against network attacks.
- NetShield广告拦截器： Blocks ads, trackers, and malware at the DNS level. This feature protects against online threats and DNS leaks while browsing.
- VPN加速器： Uses advanced networking to boost internet speeds. The VPN Accelerator makes a noticeable difference when connecting to distant server locations.

1. 隐私和无日志政策
ProtonVPN： Proton VPN has a strict no-logs policy verified by a third-party audit. Proton VPN passed this review with no issues found. The VPN company is based in Switzerland, which has some of the world’s strongest privacy laws. Proton VPN also publishes a transparency report showing how few legal requests it receives. Your internet service provider cannot see your online activities when connected through the encrypted VPN tunnel.
Bitdefender VPN： Bitdefender VPN claims a no-logs policy for browsing history and traffic logs. However, it does log some technical data including user and device IDs for fraud prevention. Hashed user data and randomly generated tokens may be stored. The privacy policy has been criticized for lacking clarity, and no independent audit has confirmed these claims. The data processor processes data according to Bitdefender’s instructions.
2. 服务器网络
ProtonVPN： Proton VPN has over 8,600 servers in 112 countries. That’s a massive server network for a VPN provider. Every server is a physical machine owned and operated by Proton, not rented from third parties.
Bitdefender VPN： Bitdefender VPN offers over 4,000 servers in 54 countries. That’s a decent network but less than half of what Proton offers. The servers are powered by Hotspot Shield’s infrastructure, not owned by Bitdefender directly.
3. Encryption and VPN Protocols
ProtonVPN： Proton VPN uses AES-256 encryption with Perfect Forward Secrecy. It supports OpenVPN, IKEv2, WireGuard, and its own Stealth VPN protocol. The Stealth protocol disguises VPN tunnel traffic as normal internet traffic to bypass censorship. Proton services also include encrypted tunnel protection on every connection.
Bitdefender VPN： Bitdefender VPN also uses AES-256 encryption. It primarily runs on the Catapult Hydra protocol for speed. It also supports WireGuard and OpenVPN as VPN protocols. However, it lacks any obfuscation protocol to bypass internet censorship. A Bitdefender Premium VPN review shows these protocols handle most web browsing needs well. The UK server and other server locations connect quickly.
4. 安全特性
ProtonVPN： Proton VPN includes a kill switch, DNS leak protection, and NetShield ad blocking. It also offers Secure Core servers that route traffic through privacy-friendly countries. Tor over VPN is available for users who need extra anonymity on the Tor network. You can also run a DNS leak test to confirm your VPN connection is secure. Proton VPN offers Tor servers for maximum privacy.
Bitdefender VPN： Bitdefender VPN has a kill switch and split tunneling. It also includes an ad blocker and anti-tracker feature as additional features. Public Wi-Fi protection turns on automatically when you join unsecured networks. The Bitdefender product covers online security against online threats. However, there are no double VPN or Tor features available.
5. Streaming and Geo-Restricted Content
ProtonVPN： Proton VPN unblocks Netflix, BBC iPlayer, Amazon Prime Video, and other major streaming services. According to Proton VPN’s website, dedicated servers are available for streaming access across multiple regions. This makes Proton VPN good for geo restricted content access. Does Proton VPN work for streaming? Yes — it handles most platforms without issues.
Bitdefender VPN： Bitdefender VPN can unblock BBC iPlayer and certain websites but struggles with Netflix US, Amazon Prime Video, and Disney+. It does not have dedicated streaming servers. There is no way to access the same number of streaming platforms. This limits its usefulness if blocking access to geo restricted content is your main concern.
⚠️ 警告： Bitdefender VPN’s streaming support is inconsistent. If watching region-locked content matters to you, Proton VPN is the safer bet.
6. 设备兼容性
ProtonVPN： The Proton VPN app runs on Windows, macOS, iOS, Android, Linux, Android TV, and Apple TV. The Linux app has a full GUI interface. It also supports router setups for whole-network protection. Up to 10 simultaneous connections are available on paid plans. Proton apps work well across every mobile device.
Bitdefender VPN： Bitdefender VPN works on Windows, macOS, Android, and iOS only. Mobile apps are available for phones and tablets. It does not support Linux, routers, Apple TV, or Fire TV Stick. That limits how many devices and platforms you can protect. You manage everything through a Bitdefender Central account.
7. 免费方案比较
ProtonVPN： Proton VPN’s free version offers unlimited bandwidth with no ads. It’s limited to servers in five locations and one device. But there are no data caps at all, which is rare among other free VPNs. This is a secure VPN option even on the free tier.
Bitdefender VPN： Bitdefender’s free version requires an active Bitdefender security subscription. It caps data at 200MB per day. That’s barely enough for light email checking and not useful for browsing or streaming.
8. 客户支持
ProtonVPN： Proton VPN support staff can be reached through email and a support ticket system. There is no live chat support. Response times vary, and connection times for getting a reply can be slow during peak hours. You can visit Proton VPN’s website for documentation and guides.
Bitdefender VPN： Bitdefender offers 24/7 live chat support, email, and phone support for all Bitdefender’s products. However, the general support team handles all Bitdefender products, not just VPN. This means you may get a general support team member instead of specialist providers who know VPN internals. Desktop notifications alert you when the latest version is available.
9. 定价和成本
让我们来并排比较一下这些定价方案。
| 计划类型 | ProtonVPN | Bitdefender VPN |
|---|---|---|
| 自由的 | $0/month (unlimited data) | 200MB/day (with security sub) |
| 入场费 | 每月 2.99 美元（Plus 版） | 59.99美元/年（全面安保） |
| 中级 | 每月 7.99 美元（无限流量） | 79.99美元/年（高级安全套餐） |
| 顶级 | — | 119.99美元/年（终极加强版） |
ProtonVPN： At $2.99/month on a 2-year plan, Proton VPN is affordable for a standalone premium VPN. The free plan makes it easy to test before you pay. You only pay for VPN features — no forced antivirus bundle.
Bitdefender VPN： Bitdefender VPN can’t be bought on its own outside of the security suite. The cheapest plan with unlimited VPN is $79.99/yr (Premium Security). That’s good value if you also need antivirus, but expensive if you only want a VPN.
