什么是私人互联网接入？
Private Internet Access (PIA) is a VPN service that hides your IP address and encrypts your internet traffic.
It runs one of the largest server networks in the VPN industry with 35,000 servers across 91 countries.
PIA is known for its open-source apps, verified no-logs policy, and unlimited device connections.

PIA gives you 35,000 servers in 91 countries, unlimited device connections, and a verified no-logs policy. It’s one of the most trusted budget VPNs on the market.
私人互联网接入定价
Here’s what Private Internet Access costs in 2026.
| 计划 | 价格 | 最适合 |
|---|---|---|

私人互联网接入的主要优势
Here’s why Private Internet Access stands out from other VPNs:

- Verified No-Logs: Deloitte audited PIA’s servers and confirmed zero user data stored. Your browsing history stays private.
- 开源代码： PIA’s apps are fully open source. Anyone can inspect the code for hidden trackers or backdoors.
- MACE广告拦截器： Block ads, trackers, and malware at the DNS level. No extra browser extension needed.
- 分裂隧道： Choose which apps go through the VPN and which use your regular connection. Great for banking and streaming at the same time.

什么是AdGuard VPN？
AdGuard VPN is a privacy-focused VPN made by the same company behind the popular AdGuard ad blocker.
It uses a custom protocol that disguises VPN traffic as regular HTTPS browsing.
AdGuard VPN is based in Cyprus, outside the 5/9/14 Eyes surveillance alliances.
AdGuard VPN
AdGuard VPN offers a free plan with 3 GB of data, built-in DNS ad blocking, and a proprietary protocol that masks your VPN traffic. It’s a solid pick for casual users who want basic privacy.

| 计划 | 价格 | 最适合 |
|---|---|---|
| 1 个月 | 每月 11.99 美元 | Quick testing |
| 1 年 | 每月 3.99 美元 | Budget-minded annual users |
| 2年 | 每月 2.40 美元 | Maximum savings |
免费试用： AdGuard VPN has a free plan with 3 GB of data per month. No credit card required.
退款保证： 30-day refund on yearly and 2-year plans. Monthly plans are not covered.
📌 笔记： The free plan gives you 3 GB every month. That’s enough for light browsing but not for streaming or heavy downloads.
⚠️ 警告： The free plan caps your speed at 20 Mbps. You’ll need a paid plan for faster connections.
Key Benefits of AdGuard VPN
Here’s why AdGuard VPN might be the right choice for you:
- 免费方案： Get 3 GB of data every month at no cost. Perfect for testing the service before you pay.
- DNS Ad Blocking: Block ads and trackers using AdGuard’s own DNS servers. No need for a separate ad blocker app.

- Cyprus Jurisdiction: Based outside the 5/9/14 Eyes surveillance alliances. Your data stays away from mass government snooping.
- 跨平台支持： Works on Windows, macOS, 安卓, iOS, Linux, Android TV, and browser extensions for Chrome, Firefox, and Edge.
- 分裂隧道： Choose which apps or websites use the VPN. Route sensitive traffic through the tunnel while keeping local apps on your regular connection.

功能对比
Let’s break down how Private Internet Access and AdGuard VPN compare across 9 key areas.
Each feature gets a clear winner so you know exactly where each VPN shines.
| 特征 | 私人互联网接入 | AdGuard VPN |
|---|---|---|
| 起价 | 每月 2.03 美元 | 每月 2.40 美元 |
| 免费计划 | ❌ | ✅ (3 GB/month) |
| 服务器 | 35,000 in 91 countries | 800+ in 53 countries |
| 同时连接 | 无限 | 10 |
| 无日志审计 | ✅ (Deloitte) | ❌ |
| 开源应用程序 | ✅ | ❌ |
| 广告拦截器 | ✅ (MACE) | ✅ (DNS-based) |
| 终止开关 | ✅ (Regular + Advanced) | ✅ |
| 分裂隧道 | ✅ | ✅ |
| 最适合 | Power users & privacy fans | Casual users & ad blocking |
1. 服务器网络
私人互联网接入： PIA runs 35,000 servers spread across 91 countries. That includes servers in all 50 US states. More servers mean less crowding and faster speeds during peak hours.
AdGuard VPN： AdGuard VPN has about 800 servers in 65 locations across 53 countries. That’s a much smaller network. You may notice slower speeds on popular servers during busy times.
💡 测试结果： PIA’s network is over 40 times larger than AdGuard VPN’s. If you 旅行 often or need servers in specific regions, PIA gives you far more choices.
2. 速度和性能
私人互联网接入： PIA’s average speed loss is about 49% of your base speed. That’s enough for browsing and streaming in HD. However, bandwidth-heavy tasks like 4K video or large downloads may suffer.
AdGuard VPN： AdGuard VPN drops speed by about 20% on nearby servers. That’s better than PIA for short-distance connections. But paid users average around 58 Mbps, and the free plan caps you at 20 Mbps.
3. Privacy and Security
私人互联网接入： PIA uses AES-256 encryption with OpenVPN and ChaCha20 with WireGuard. Its no-logs policy has been audited by Deloitte multiple times. PIA’s apps are fully open source, so anyone can check the code.
AdGuard VPN： AdGuard VPN uses AES-256 encryption and a proprietary protocol. It claims a no-logs policy, but no third party has verified this. The custom protocol hasn’t been independently audited either.
⚠️ 警告： AdGuard VPN’s proprietary protocol may perform well, but without an independent audit, you’re trusting their word. PIA’s open-source code and Deloitte audit offer much stronger proof.
4. Ad and Tracker Blocking
私人互联网接入： PIA includes MACE, a DNS-level ad and tracker blocker. It blocks ads, malware domains, and tracking scripts before they load. You don’t need a separate browser extension.
AdGuard VPN： AdGuard VPN lets you choose DNS servers that block ads and trackers. It comes from the same company that makes one of the best ad blockers around. This is where AdGuard’s brand really shines.
5. Streaming and Unblocking
私人互联网接入： PIA has streaming-ready servers that can unblock Netflix, Disney+, and BBC iPlayer. Results can vary by location, but PIA works with most major platforms.
AdGuard VPN： AdGuard VPN can unblock Netflix, Disney+, and BBC iPlayer. But it struggles with Amazon Prime and Peacock. Users also report buffering and longer load times on some platforms.
6. 设备连接
私人互联网接入： PIA allows unlimited simultaneous connections. Protect your phone, laptop, tablet, router, and smart TV all at once. No extra cost for adding devices.
AdGuard VPN： AdGuard VPN allows up to 10 devices on paid plans. That’s enough for most families. But power users with many devices may find it limiting.
7. 紧急停止开关
私人互联网接入： PIA offers two kill switches. The regular one stops traffic when the VPN drops. The advanced one blocks all internet unless the VPN is active. Both are available on Windows and macOS.
AdGuard VPN： AdGuard VPN has a standard kill switch that cuts your connection if the VPN drops. It works, but there’s no advanced option like PIA offers.
8. 分段隧道
私人互联网接入： PIA’s split tunneling lets you exclude specific apps and IP addresses from the VPN tunnel. You can bank on your regular connection while streaming through the VPN.
AdGuard VPN： AdGuard VPN also supports split tunneling. You can choose which apps or websites use the VPN. It works on both desktop and mobile apps.
9. 定价与成本
让我们来并排比较一下这些定价方案。
| 计划 | 私人互联网接入 | AdGuard VPN |
|---|---|---|
| 自由的 | ❌ | 3 GB/month (20 Mbps cap) |
| 月度 | 每月 11.99 美元 | 每月 11.99 美元 |
| 6个月/1年 | $7.50/month (6 months) | $3.99/month (1 year) |
| Best Long-Term | $2.03/month (2 years + 4 months) | $2.40/month (2 years) |
私人互联网接入： PIA’s best deal is the 2-year + 4-month plan at $2.03/month. It also never raises prices on renewal. You get unlimited devices and full features on every plan.
AdGuard VPN： AdGuard VPN’s 2-year plan costs $2.40/month. The annual plan at $3.99/month is a decent middle ground. AdGuard also has a free tier, which PIA doesn’t offer.
💡 测试结果： PIA is $0.37/month cheaper on long-term plans. But if you want to try before buying, AdGuard VPN’s free plan lets you test without spending anything.
