Norton VPNとは何ですか?
Norton VPN is a virtual private network from Norton, the antivirus brand owned by Gen.
For years, it was sold as Norton Secure VPN.
The old Norton Ultra VPN tier now goes by Norton VPN Plus.

The app masks your IP addresses and encrypts your online traffic.
It works on Windows, Mac, Android, and iOS デバイス.
You can also bundle it with Norton 360 for antivirus software.

ノートンVPN
A one-tap VPN app from a known security company. It adds a kill switch, tracker blocking, and Dark Web Monitoring.
ノートンVPNの価格
Here’s what Norton VPN costs in 2026. Prices are listed per month.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 標準 | 月額3.33ドル | コアVPN保護を求めるソロユーザー |
| デラックス | 月額4.17ドル | Couples who want extra privacy tools |
| セレクトプラス | 月額8.33ドル | Families covering many mobile devices |
Pricing verified September 2026.

無料トライアル: There’s no free Norton VPN plan. The refund window works as your trial.
返金保証: 60 days for annual subscribers and 14 days on monthly plans.
📌 注記: Norton accepts a credit card or PayPal, but not 暗号. Android buyers can also pay through the Play Store with Google Pay.
⚠️ 警告: Renewal prices climb. Norton’s sales pages have listed a $5 monthly single-device plan. Five devices cost $3.33/month, renewing at $6.66. Ten devices cost $5/month, renewing at $8.33. A $9.99 first-year promo renews at $49.99 per year. These figures differ from the plan table above, so confirm the total at checkout.
Norton VPNの主な利点
Here’s what makes Norton VPN worth a look:
- Kill Switch and Split Tunneling: The kill switch blocks traffic if your VPN connection drops. Split tunneling on Windows and Android lets chosen apps skip the VPN.
- Public Wi-Fi Alerts: Compromised Network Detection warns you before you join a risky hotspot. That lowers your identity theft risk in cafés and airports.
- ダークウェブモニタリング: Norton alerts you if your personal details appear on the dark web. Many VPNs don’t include anything like it.
- トラッカーブロッカー: The ad tracker blocker works across all platforms. Pages load with fewer ads following you around.
- Protocol Choice: Pick WireGuard, OpenVPN, or Mimic, Norton’s own custom security protocol. Switch in the settings tab if a server feels slow.
- ダブルVPN: Traffic can pass through two servers for extra anonymity. You can also automatically connect whenever you join public networks.

私たちのチームが気づいたこと
私たちの 作家 signed up for Norton VPN on desktop and phone. Here’s what stood out:

Norton VPNのメリットとデメリット
✅ メリット
- Beginner-friendly mobile apps with quick connect to the fastest server
- Kill switch, ad tracker blocking, and Dark Web Monitoring included
- 60-day money-back guarantee on annual subscriptions
- Unblocks US Netflix, Prime Video, and BBC iPlayer
❌ デメリット
- The iOS app lacks a kill switch and split tunneling
- No IPv6 leak protection, so IPv6 addresses stay exposed
- US headquarters falls inside the 5/9/14 Eyes alliances
OpenVPN とは何ですか?
OpenVPN is an open source tunneling protocol first released in 2001.
It builds a secure tunnel with SSL/TLS, short for secure sockets layer.
The OpenVPN company, once called OpenVPN Technologies, sells 仕事 products too.

The free OpenVPN Community Edition lets anyone run a personal VPN server.
It supports operating systems from Windows and Android to Tomato and Solaris.
Surfshark, エクスプレスVPN, and Norton VPN each count as an OpenVPN compatible service.

🏆 Winner: OpenVPN
Open code you can inspect and host yourself. Scale from one laptop to site-to-site business links.
OpenVPNの価格設定
Here’s what OpenVPN costs in 2026. Personal use can stay free.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 無料 | $0 | Home labs and self-hosted personal VPNs |
| 成長 | 月額7ドル | Small teams that need remote access |
| 企業 | カスタム | Large firms linking offices and sites |
Pricing verified September 2026.

無料トライアル: The Community Edition is free forever. You only pay for the machine that hosts it.
返金保証: No refund window is advertised. Growth bills monthly, so you can stop whenever you like.
📌 注記: Is OpenVPN free in practice? The OpenVPN software is. Cloud hosting, a static IP, and your setup hours are not.
⚠️ 警告: The free edition gives you no servers and no help desk. One manual configuration mistake can leak sensitive data.
OpenVPNの主な利点
Here’s why OpenVPN still earns its reputation:
- オープンソースコード: Anyone can read the code and report flaws. A global developer community reviews it and ships fixes fast.
- Flexible Encryption: Choose AES or Blowfish and set your own key length. It taps the OpenSSL library for extra options.
- TCP or UDP: The transmission control protocol delivers every packet in order. The user datagram protocol skips those checks, so it runs faster.
- Firewall Friendly: It passes through firewalls and NAT gateways well. TLS auth adds an HMAC firewall that drops unsigned packets.
- 完全な前方秘匿性: Fresh session keys limit damage from a breach. One stolen key won’t unlock all past traffic.
- IPv4 and IPv6: It carries both address types. That keeps modern private networks covered without extra tools.

1. How the VPN Tunnel Works
ノートンVPN: Norton’s connection runs in five steps: initiation, encryption, tunneling, IP masking, and the return path. You tap connect, and a few seconds later your data travels to a Norton server. That’s how this VPN works for most people, with zero setup.
https://youtu.be/vB3jd5KiBn8?si=u6TciXhkyYo1Kxxq
オープンVPN: OpenVPN works at the transport layer. It verifies VPN clients and servers and builds secure connections. Then it wraps each packet with routing data and encryption. For authentication OpenVPN relies on user credentials or digital certificates from a public key infrastructure.

2. 暗号化とVPNプロトコル
ノートンVPN: Like most VPNs, Norton relies on AES-256. For encryption protocols, you can choose WireGuard, the OpenVPN protocol, or Mimic. It also offers DNS and WebRTC leak protection, though IPv6 leaks aren’t covered.

オープンVPN: OpenVPN supports AES, Blowfish, and other encryption algorithms. You control the encryption ciphers, key lengths, and how encryption keys are handled. A hash message authentication code confirms packets weren’t changed in transit.
⚠️ 警告: OpenVPN is only as strong as its settings. Is OpenVPN safe? It beats older tunneling protocols like PPTP and most VPN protocols. But a weak cipher choice undoes that.
3. Privacy & Logging
ノートンVPN: Norton says it follows a no logs policy that a third party audited. Yet the NortonLifeLock Global Privacy Statement allows limited data collection. That includes email addresses, timestamps, and usage data for debugging. Norton is also based in the US, a 5/9/14 Eyes member.

オープンVPN: OpenVPN keeps only the log information you configure. On your own OpenVPN server, you decide what gets stored, if anything. Your browsing activities stay in your hands, along with the legal responsibility.

4. Speed & Connection Speeds
ノートンVPN: Published speed tests show Norton’s speeds dropping 40% to 55% on average, depending on location. Local servers stay fast, and the best sessions reach a 950Mbps+ median. A 日本 server lost 73%, so distance hurts Norton Secure VPN’s performance.
オープンVPN: OpenVPN is slower than WireGuard and some other VPN protocols. OpenVPN UDP runs faster because the UDP protocol doesn’t confirm delivery. OpenVPN TCP is steadier on shaky networks. Real speed depends on your server and internet service provider.
💡 プロのヒント: Run a speed test with the VPN off, then on. Compare a nearby server with a distant one before you commit.
5. Server Locations & Streaming
ノートンVPN: Reviews have counted around 1,500 servers in 28 to 29 countries, with country-only selection. That’s fewer countries than other VPNs like ノードVPN. Norton Secure VPN’s servers unblock US and Australian Netflix, Prime Video, and BBC iPlayer. Netflix UK, Canada, Japan, and Disney Plus failed. It also can’t get past firewalls in China or Iran.

オープンVPN: OpenVPN has no network of VPN servers. You rent or host OpenVPN servers yourself, so you choose every location. A single self-hosted IP rarely unlocks streaming services, since you don’t share it with other users.

⚠️ 警告: Norton’s network keeps changing. Its site now lists 130+ server locations with city-level choice, so older server counts may be outdated.
6. Apps, Kill Switch & Split Tunneling
ノートンVPN: Norton Secure VPN’s apps stay simple everywhere. The Windows app and Android smartphones get both a kill switch and split tunneling. The iOS app is easy to use but skips both. Quick connect picks the fastest VPN server near you.

オープンVPN: OpenVPN Connect is the official OpenVPN client, and the OpenVPN GUI covers Windows desktops. You import a .ovpn file, a plain 文章 config you can edit. The client software feels clunkier on phones than on desktops.
7. Tracker Blocking & Bonus Features
ノートンVPN: Norton Secure VPN’s features include ad tracker blocking, Double VPN, and Dark Web Monitoring. Hiding online activities from your ISP also helps prevent bandwidth throttling. Higher plans hold the advanced features, like a パスワードマネージャー, and the top tier brings parental controls.
オープンVPN: OpenVPN skips consumer extras. You extend it with third-party apps, scripts, and plugins instead. Business plans add DNS security and content filtering for teams.
8. Identity & Malware Protection
ノートンVPN: Compromised Network Detection flags an unsecured network before you connect. Norton 360 bundles add antivirus features and malware blocking. That makes Norton more than a VPN app for families worried about identity theft.

オープンVPN: OpenVPN has no malware scanner or identity alerts. It protects data traffic while it moves, and nothing more. Pair it with separate antivirus software.
9. Business Use & Remote Access
ノートンVPN: Norton pitches device protection to 中小企業 too. But it has no site-to-site tunnels and no admin console for managing VPN users.

オープンVPN: This is OpenVPN’s home turf. Companies use it for remote access, secure IoT links, and creating VPN tunnels between offices. OpenVPN Access Server adds a web admin panel for managing OpenVPN connections.

10. 価格設定とコスト
Here are both price lists side by side.
| ティア | ノートンVPN | オープンVPN |
|---|---|---|
| エントリ | 標準プラン:月額3.33ドル | 無料:0ドル |
| 真ん中 | デラックス:月額4.17ドル | Growth: $7/month |
| トップ | セレクトプラス:月額8.33ドル | エンタープライズ:カスタム |
ノートンVPN: Norton’s plans cost little for a finished service with servers included. Watch renewal rates, which rise after the first term. Annual subscriptions also get the longer refund window.
オープンVPN: The free tier looks unbeatable, but hosting still costs money. For teams, Growth at $7/month is a good deal next to building access controls yourself.

私たちのレビューで取り上げられなかったこと
This comparison focused on home users and small teams. We didn’t benchmark OpenVPN Access Server at enterprise scale or test Norton on smart TVs. Norton’s plan names and server count changed recently, so some details may shift. Our full Norton Secure VPN review goes deeper on setup. If you manage hundreds of VPN users, run your own pilot first.

Norton VPN and OpenVPN solve different problems. Norton is a finished product. OpenVPN is the engine behind many VPN services and company virtual private networks.
Is Norton Secure VPN worth it? For beginners who want streaming, a kill switch, and identity alerts in one app, yes. Just watch renewal prices and the missing IPv6 protection.
OpenVPN takes the overall win for its open code, free tier, and flexibility. In 2026, it still balances security and compatibility well, even with WireGuard around. Security researchers still list it with the safest VPN protocols. If you can handle setup, it’s the stronger long-term pick.
