Now let’s compare Private Internet Access vs Avast VPN across 9 key categories. Each section shows how both VPN services handle a specific feature.
| 特征 | 私人互联网接入 | Avast VPN |
|---|---|---|
| 起价 | 每月 2.03 美元 | 第一年 49.99 美元 |
| 免费试用 | ❌ | ✅ 60天 |

| 开源应用程序 | ✅ | ❌ |
| 分裂隧道 | ✅ | ✅ |
| 终止开关 | ✅（常规+进阶） | ✅ |
| 最适合 | 注重隐私的高级用户 | Casual browsing and Avast users |
1. 服务器网络
私人互联网接入： PIA has over 35,000 VPN servers spread across 91 countries. That includes coverage in all 50 US states, which is rare among VPN providers. More server locations mean less crowding and better connection speeds during peak hours.
Avast VPN： Avast SecureLine VPN has around 700 servers in 34 countries. That’s a small network compared to most VPN services. Fewer Avast SecureLine VPN servers can lead to slower download speeds during busy times, especially on distant server locations.
2. 隐私和安全
私人互联网接入： PIA has a strict no-logs policy verified by Deloitte through independent audits. The VPN does not store browsing history, DNS queries, connection data, or your real IP address. PIA also publishes quarterly transparency reports showing how it handles legal requests.
Avast VPN： Avast claims a no-logs policy but has not completed any independent audit to back it up. The service records timestamps and data volumes for up to 35 days. Avast’s parent company was fined $16.5 million by the FTC in 2024 for selling user data through a subsidiary called Jumpshot.
⚠️ 警告： If user privacy is your top priority, the lack of independent audits and the FTC fine are major concerns for Avast SecureLine VPN.
3. Encryption and VPN Protocols
私人互联网接入： PIA offers AES-256 encryption over the OpenVPN protocol and ChaCha20 using WireGuard. Users can customize the encryption level and choose between protocols based on their needs. This flexibility is helpful for power users who want to balance speed and security.
Avast VPN： Avast SecureLine supports OpenVPN, WireGuard, and its own Mimic protocol. Mimic is designed to disguise VPN traffic as regular browsing data. However, there are fewer customization options compared to PIA’s approach.
4. 速度和性能
私人互联网接入： PIA’s average download speed loss is around 49%, which varies by server location and protocol. Speeds are generally fine for streaming services and web browsing. Performance on Windows 使用 OpenVPN tends to be better than WireGuard in some tests.
Avast VPN： Avast delivers decent connection speeds on nearby servers. However, speed drops are significant when connecting to distant locations. The smaller server network means fewer options for avoiding congested nodes.
5. 流媒体播放和解锁
私人互联网接入： PIA has streaming optimized servers that can access Netflix, Disney+, and Amazon Prime Video. However, unblocking streaming content is not always consistent. Some streaming services like BBC iPlayer may not work every time.
Avast VPN： Avast can access Netflix, Disney+, and Amazon Prime Video through its streaming optimized servers. But results with BBC iPlayer and Hulu have been mixed according to user reports. The limited number of servers makes it harder to find a working connection.
6. 紧急停止开关和泄漏保护
私人互联网接入： PIA provides two types of kill switches. The regular kill switch activates when the VPN connection drops. The advanced kill switch blocks all internet traffic unless PIA is connected. Both help prevent DNS leaks and keep your actual IP address hidden.
Avast VPN： Avast includes a kill switch that disconnects your internet connection if the VPN drops. It also has DNS leak protection and WebRTC leak protection built in. These features are standard but fewer in number compared to PIA’s dual kill switch setup.
7. 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. This means you can route banking sites through your regular connection while keeping browser traffic encrypted. PIA also supports 自动化 rules that trigger connections based on your network.
Avast VPN： Avast SecureLine VPN offers basic split tunneling on supported platforms. You can choose which apps go through the VPN and which use your direct internet connection. However, it lacks the IP address exclusion and 自动化 features found in PIA.
8. 设备支持和连接
私人互联网接入： PIA allows unlimited simultaneous connections. Install it on your phone, laptop, tablet, router, and every other device you own. PIA also offers a dedicated command line app for Linux and browser extensions for Chrome and Firefox.
Avast VPN： Avast allows 10 devices on one subscription. It works on Windows, macOS, Android, iOS, and Android TV. There are no browser extensions or router support, which limits coverage for smart home devices.
9. 定价和成本
| 计划类型 | 私人互联网接入 | Avast VPN |
|---|---|---|
| 月度 | 每月 11.99 美元 | 无月付选项 |
| 6-Month / 1-Year | $7.50/month (6-mo) | 第一年 49.99 美元 |
| 长期 | $2.03/month (2-yr) | 第一年 49.99 美元（终极版） |
| 免费试用 | ❌ | ✅ 60天 |
| 退款 | 30天 | 30天 |
私人互联网接入： PIA is one of the cheapest VPN options for long-term plans at $2.03/month. The price stays the same at renewal, which is rare. The monthly rate of $11.99 is slightly above average, but the long-term deals make PIA an affordable VPN choice.
Avast VPN： Avast’s first-year pricing looks competitive at $49.99. But renewal prices jump significantly — often doubling the original cost. There is no monthly plan available, which limits flexibility for users who don’t want a long commitment.

我们的评测没有涵盖的内容
This comparison focused on individual users and small households. We tested Private Internet Access and tested PIA across core features, but didn’t evaluate enterprise-level setups, custom VPN router configurations, or specialized use cases like torrenting performance across every server. Speed tests vary by location and time of day, so your results may differ. If you need a VPN specifically for a 商业 network, your priorities will look different from what we’ve covered here.

Private Internet Access 在 7 个类别中赢得了 5 个。
最适合： Privacy-focused users, families with many devices, long-term VPN subscribers
Private Internet Access and Avast VPN serve different types of users. PIA is a dedicated VPN service built for privacy and flexibility. Avast SecureLine VPN is a simple add-on for users already using Avast antivirus.
Avast VPN works well for casual browsing and public Wi-Fi protection. The 60-day trial is genuinely useful for first-time VPN users who want to test before buying.
But if you want a verified no-logs policy, unlimited connections, and a massive server network, PIA is the stronger pick. It may not be the flashiest option, but it checks every box you’d expect from a top-tier VPN. The long-term pricing at $2.03/month with no renewal increases makes it a clear value winner too.
