1. サーバーネットワーク
プライベートインターネットアクセス: PIA runs 35,000 VPN servers across 91 countries. It covers all 50 US states, which is rare among VPN providers. More server locations mean less crowding and faster connection speeds in most regions.
ノートンVPN: Norton Secure VPN has roughly 1,500 servers in 28 countries. You cannot pick a specific city — only a country. This limits options if you need a VPN server in a particular region for better download speeds.
2. Privacy and No-Logs Policy
プライベートインターネットアクセス: PIA has a strict no-logs policy verified by Deloitte through independent audits. The privacy policy clearly states PIA does not collect browsing history, IP addresses, connection timestamps, DNS queries, or DNS requests. PIA also runs its own DNS servers and publishes quarterly transparency reports. Independent testing confirms no DNS leaks when connected.
ノートンVPN: Norton claims a no-logs policy but collects some usage data for debugging. The NortonLifeLock Global Privacy Statement outlines what data is gathered. Norton is also headquartered in the US, which is part of the Five Eyes alliance — a concern for some VPN users.
⚠️ 警告： Norton VPN does not mask IPv6 addresses, which can expose your real IP address even when the VPN connection is active.
3. 速度とパフォーマンス
プライベートインターネットアクセス: PIA’s average download speed loss sits around 49%. Performance varies by server location and VPN protocol used. According to PIA’s documentation, the OpenVPN protocol performs better than WireGuard on Windows for some users.
ノートンVPN: Norton’s speeds decreased by about 40% on average during speed tests. The VPN can reach high speeds on local servers. However, distant server locations like Japan showed drops of up to 73%, which affects connection speed for users far from their chosen server.
4. キルスイッチ
プライベートインターネットアクセス: PIA provides two types of kill switches on Windows and macOS. The regular kill switch blocks internet traffic if the VPN connection drops. The advanced kill switch blocks all traffic unless the VPN is connected — even before you turn it on.
ノートンVPN: Norton Secure VPN includes a kill switch on most platforms. It prevents data leaks if the VPN connection fails. However, the iOS app does not include a kill switch, which is a gap for iPhone ユーザー。
5. スプリットトンネリング
プライベートインターネットアクセス: PIA supports split tunneling across all platforms. You can exclude specific apps and IP addresses from the VPN tunnel. This lets you route browser traffic through the VPN while keeping other apps on your regular internet connection.
ノートンVPN: Norton offers split tunneling only on the Windows app and Android smartphones. The iOS app and macOS app do not support this feature. If you use Apple devices, you won’t have this option.
6. ストリーミングとブロック解除
プライベートインターネットアクセス: PIA has streaming optimized servers that can unblock services like Netflix and Disney Plus. The VPN also helps prevent ISP throttling on streaming services. However, unblocking streaming content can be inconsistent depending on the server location. PIA also works with Amazon Prime Video and BBC iPlayer.
ノートンVPN: Norton can unblock US and Australian Netflix plus Amazon Prime Video and BBC iPlayer. It does not work with Netflix UK, Canada, Japan, or Disney Plus. For streaming services, Norton is more limited than PIA.
7. 暗号化とプロトコル
プライベートインターネットアクセス: PIA offers AES-256 encryption over the OpenVPN protocol and ChaCha20 using WireGuard. Users can customize their encryption level and choose between VPN protocols directly in the PIA app. This flexibility is useful for power users.
ノートンVPN: Norton uses AES-256 encryption. It supports WireGuard, OpenVPN, and a proprietary Mimic protocol. The Mimic protocol aims to disguise VPN traffic as normal browsing, which may help in regions that block VPN connections.
8. デバイス接続
プライベートインターネットアクセス: PIA allows unlimited simultaneous connections on one account. You can protect all your devices — phones, laptops, tablets, and more — without worrying about a device limit.
ノートンVPN: Norton limits connections based on your plan. The Standard plan covers 1 device. The Deluxe plan covers 5 mobile devices and desktops. The Select Plus plan covers 10. You’ll pay more as you add devices.
9. Bonus Security Features
プライベートインターネットアクセス: PIA offers multi-hop connections, port forwarding, a dedicated IP address option, and a command line app. It also includes Identity Guard for data breach monitoring. These features make PIA a strong pick for power users who want detailed control over their VPN connection.
ノートンVPN: Norton VPN adds antivirus software, malware blocking, dark web monitoring, parental controls, and an AI-powered scam 検出器. Norton’s bonus features focus on security beyond the VPN — identity theft protection and online privacy are baked into the package.
10. 価格設定とコスト
料金プランを並べて比較してみましょう。
| プランの種類 | プライベートインターネットアクセス | ノートンVPN |
|---|---|---|

| Renewal Price Increase | なし | Yes — up to double |
| 返金保証 | 30日間 | 60 days (annual) / 14 days (monthly) |
プライベートインターネットアクセス: PIA’s long-term plan at $2.03/month makes it an affordable VPN compared to most VPNs in the market. The price stays the same on renewal. No hidden costs or paywalled features — every plan, including monthly plans, gets the same VPN features.
ノートンVPN: Norton’s Standard plan starts at $3.33/month but renews at $6.66/month on annual subscriptions. The 10-device plan is $5/month initially. If you already use Norton 360, the VPN can be bundled for less. Norton accepts credit card and PayPal but does not support Google Pay or cryptocurrency.

💰 あなたの予算
PIA’s 2-year plan costs $2.03/month with no price increases on renewal. Norton VPN starts at $3.33/month but can double after year one.
🔌 あなたの技術スタック
PIA supports split tunneling on all platforms and offers browser extensions and mobile apps. Norton only has split tunneling on the Windows app and Android devices. Norton’s settings tab gives fewer options compared to PIA’s detailed controls.
🛡️ あなたのプライバシーのニーズ
If user privacy and online privacy are your top priorities, PIA’s audited no-logs policy and open-source apps are hard to beat. Norton logs some usage data and connection data from online activities. The VPN works well for basic privacy, but PIA offers more advanced features for protecting your browsing activities.
🎓 あなたの経験レベル
Norton VPN has a simpler interface with fewer settings to adjust. Its wi fi security tools and automatic connect feature make it easy for beginners. PIA gives you more control but requires some VPN knowledge to customize the encryption level and VPN protocols.
🆓 無料トライアルとデモ
Neither VPN offers a free plan. PIA has a 30-day money-back guarantee. Norton gives annual subscribers 60 days to decide — the longest refund window between the two.
🛟 サポートオプション
Both VPN services offer online support libraries. PIA provides 24/7 live chat. Norton provides phone support through its broader product suite for paying customers.

最適な用途: Privacy-focused users, families with many devices, budget-conscious VPN shoppers
Private Internet Access and Norton VPN serve two different types of VPN users. PIA is a pure VPN built for privacy, with a massive server network and unlimited connections. Norton VPN wraps a basic VPN inside a broader security suite with antivirus features.
Norton VPN is a solid pick if you already use Norton 360 and want everything in one place. The dark web monitoring and identity theft protection are genuine extras.
However, if you need a dedicated VPN with more server locations, better privacy controls, and lower long-term costs, Private Internet Access is the better choice.
