⚡ Quick Verdict:
- 定价： Private Internet Access starts at $2.03/mo (2-year plan) vs AdGuard VPN at $2.40/mo (2-year plan)
- 最适合： PIA for privacy-focused power users who want open-source apps and unlimited connections. AdGuard VPN for casual users who want ad blocking and a free plan.
- 主要区别： PIA has 35,000 servers across 91 countries with independently audited privacy. AdGuard VPN has 800 servers in 53 countries with no third-party audit.
- Our pick: Private Internet Access for most VPN users — larger network, verified privacy, and unlimited device connections make it the stronger choice.
Private Internet Access vs AdGuard VPN both promise to keep your internet traffic safe.
But they come from very different backgrounds.
PIA is a dedicated VPN provider with over a decade of experience protecting user privacy on public Wi-Fi networks.
AdGuard started as an ad blocker and added a VPN service later.
That difference shapes everything about how these two tools work.
One encrypts your traffic as a full-featured VPN. The other focuses on blocking ads first.

| 最适合 | 注重隐私的高级用户 | Casual users wanting ad blocking |
1. 服务器网络和位置
私人互联网接入： PIA runs 35,000 servers spread across 91 countries. That includes coverage in all 50 US states, which is useful for accessing region-locked content. The large network means less crowding on individual servers, which helps maintain connection speeds during peak hours.
AdGuard VPN： AdGuard VPN operates around 800 servers in 65 locations across 53 countries. That’s a much smaller network compared to PIA. Fewer server locations means fewer options for users who need a VPN server in a specific region.
2. 隐私与安全
私人互联网接入： PIA has a strict no-logs policy that Deloitte independently verified through multiple audits. The company publishes quarterly transparency reports showing how it handles legal requests. PIA’s privacy policy states it does not collect browsing history, connection data, DNS queries, or identifying data.
AdGuard VPN： AdGuard VPN claims a strict no-logs policy and says it does not record IP addresses, browsing history, or connection timestamps. However, no third-party audit has verified these claims. The service is based in Cyprus, which is outside the 5/9/14 Eyes alliances and complies with GDPR.
⚠️ 警告： AdGuard VPN has not undergone any third-party security audits. If verified privacy is important to you, PIA’s Deloitte-audited policy offers more confidence.
3. VPN Protocols & Encryption
私人互联网接入： PIA supports the OpenVPN protocol with AES 256-bit encryption and WireGuard with ChaCha20 encryption. Users can customize their encryption level and choose between VPN protocols based on their needs. This flexibility is valuable for power users who want control over their VPN connection.
AdGuard VPN： AdGuard VPN uses only its proprietary protocol instead of industry-standard options like OpenVPN or WireGuard. The protocol uses AES-256 encryption and is designed to make VPN traffic look like normal HTTPS browser traffic. However, this protocol has not been independently audited.
4. 广告和追踪器拦截
私人互联网接入： PIA includes MACE, a built-in ad and tracker blocker that works at the DNS level. MACE blocks DNS requests to known ad and tracking domains before they load. It’s simple but effective for blocking ads across all your devices.
AdGuard VPN： AdGuard VPN lets you choose custom DNS servers that block ads and trackers. If you already use AdGuard products, the VPN works in integrated mode with the AdGuard ad blocker for deeper ad blocking. This gives AdGuard an edge for users already using other AdGuard products.
5. 速度与性能
私人互联网接入： PIA has an average download speed loss of 49% based on published speed tests. Performance varies by server location and protocol. Upload speed loss is generally higher than download. PIA’s download speeds are still enough for casual streaming and web browsing, but not ideal for bandwidth-heavy tasks. PIA does help with ISP throttling by encrypting your internet traffic.
AdGuard VPN： AdGuard VPN’s performance is described as below average compared to premium VPNs. Published tests show around 20% speed loss on nearby servers, but connection speeds drop more on distant servers. The free version caps speeds at 20 Mbps, which limits streaming platforms and causes slow speeds during video calls or online gaming.
6. 流媒体播放和解锁
私人互联网接入： PIA has streaming optimized servers that can unblock services like Netflix and Disney Plus. However, unblocking streaming content is not always consistent. Some users report issues with Amazon Prime Video depending on the server location. PIA supports incoming connections through port forwarding, which helps with online gaming and torrent downloads.
AdGuard VPN： AdGuard VPN can access Netflix, Disney+, and BBC iPlayer. But it struggles with Amazon Prime Video and Peacock. Users have reported buffering and longer load times on some streaming platforms. Smooth, uninterrupted streaming is not guaranteed on all services. If you need to hide your real location from streaming sites, results may vary with AdGuard VPN. The support team is only reachable through a ticketing system.
7. 设备连接
私人互联网接入： PIA offers unlimited simultaneous connections on every plan. You can protect all your devices — desktop apps, mobile devices, and even a VPN router — without worrying about hitting a cap. This is rare among VPN providers.
AdGuard VPN： The paid plans allow up to 10 simultaneous connections. That’s enough for most users, but it falls short compared to PIA’s unlimited policy. The free plan has the same 10-device limit.
8. Split Tunneling & Kill Switch
私人互联网接入： PIA’s split tunneling lets you exclude specific apps and IP addresses from the VPN tunnel. PIA also provides two types of kill switches — a regular one and an advanced kill switch on Windows and macOS. The advanced version blocks all internet traffic even when the VPN is turned off.
AdGuard VPN： AdGuard VPN supports split tunneling, letting you choose which apps or websites use the VPN connection. It also includes a kill switch to prevent data leaks if the VPN connection drops. Both features work across the desktop apps and mobile apps.
9. 应用和平台支持
私人互联网接入： PIA offers VPN apps for Windows, macOS, Linux (including a command line app), Android, and iOS. The Windows version and Windows PC app have full feature parity. Browser extensions are available for Chrome and Firefox. PIA also supports router setups for covering all your devices at once. You can download the PIA app from the Apple App Store or Google Play. How many servers does PIA have? The answer is 35,000 across 91 countries, including virtual servers in some locations. All PIA apps are open-source.
AdGuard VPN： AdGuard VPN covers Windows, macOS, Android, iOS, Android TV, and Linux. The desktop apps and mobile apps both support all the features including split tunneling. Browser extensions work with Chrome, Firefox, and Edge. AdGuard VPN’s apps are easy to use apps with a simple interface, but the source code is not publicly available for inspection. AdGuard DNS settings can be configured within the app to block ads on certain websites.
10. 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 | ❌ | 每月 3 GB 流量（20 Mbps 上限） |
| 月度 | 每月 11.99 美元 | 每月 11.99 美元 |
| 6个月/1年 | 每月 7.50 美元（6 个月） | 每月 3.99 美元（1 年） |
| 长期 | 每月 2.03 美元（2 年 4 个月） | 每月 2.40 美元（2 年） |
私人互联网接入： PIA’s long-term plan at $2.03/month is one of the most affordable VPN options. The 2-year plan includes 4 extra months free. PIA also locks in your renewal price, so you won’t pay more later.
AdGuard VPN： AdGuard VPN’s 2-year plan costs $2.40/month, slightly higher than PIA. But AdGuard offers a free plan that PIA doesn’t have. If you just need occasional VPN use, the free version might be enough to keep your data private.

What Our Review Didn’t Cover
This comparison focused on individual users and small households. We didn’t test enterprise VPN features, dedicated IP address performance, or how either service handles online gaming latency at scale. We also didn’t run full speed tests on every US server or test VPN block ads performance on all browser traffic scenarios. Our observations are based on the April 2026 versions of both VPN apps. AdGuard puts priority on ad blocking while PIA covers privacy features more broadly. If you need a virtual private network for a large team, your priorities may differ from what we’ve covered here.

🏆 优胜者：私人互联网接入
Private Internet Access wins 4 out of 7 categories.
最适合： Privacy-focused VPN users, large households needing unlimited connections, and anyone who values independently audited security.
Private Internet Access and AdGuard VPN serve different types of VPN users. PIA is a full-featured VPN provider built for people who care about privacy, transparency, and flexibility. Its open-source apps, Deloitte-audited no-logs policy, and unlimited bandwidth make it the stronger overall choice.
AdGuard VPN works well for casual users who want a quick VPN connection with built-in ad blocking. The free plan is a genuine perk for light users. But the smaller server network, lack of audits, and limited connections hold it back from competing with dedicated VPN providers.
If you want a reliable VPN service you can trust with your online privacy, PIA is the better pick.

PIA VPN每月费用是多少？
The monthly plan costs $11.99. The 6-month plan drops to $7.50/month. The best deal is the 2-year plan at $2.03/month — a cheap VPN price that also includes 4 extra months free. Check Private Internet Access deals on their website for any seasonal promotions. PIA is a quality VPN that gives you a day money back guarantee of 30 days.
AdGuard VPN 有免费套餐吗？
Yes. The free version gives you 3 GB of data every month with access to a few server locations. Download speeds are capped at 20 Mbps, which means slow speeds for data intensive tasks like video calls or streaming. You can buy AdGuard VPN paid plans for full speeds and unlimited data. AdGuard offers a money back guarantee of 30 days on annual and 2-year plans.
Which is better: Private Internet Access or AdGuard VPN?
For most users, PIA is the better choice and the best VPN in this matchup. Private Internet Access makes it easy to protect all your devices with unlimited connections. PIA’s servers cover 91 countries. AdGuard VPN is a decent option if you want a free plan, but AdGuard VPN’s apps lack support for standard VPN protocols. If you have tested Private Internet Access and tested PIA yourself, you’ll notice the larger server network and better privacy features.
