Tailscaleとは何ですか?
Tailscaleは、WireGuardプロトコルに基づいて構築されたゼロトラストメッシュVPNです。
It links your own devices into a private network called a tailnet.
Each device gets a stable 100.x.y.z IP address.
Devices talk to each other directly, not through Tailscale servers.
That makes it a secure networking tool, not a privacy VPN.
Developers, IT teams, and home lab fans use it to reach machines from anywhere.
This short tutorial shows how to install Tailscale and connect your first device.
尾秤
Connect laptops, servers, and phones into one private network. The free plan covers up to 100 devices. Setup takes minutes, not days.
テールスケール価格設定
Here’s what Tailscale costs for personal use in 2026.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 個人的 | 永久無料$0 | Individual users, home labs, and learning the basics |
| パーソナルプラス | 月額5ドル | Households or small groups that need more seats |

無料トライアル: The Personal plan is free forever, so you can test everything risk free. Sign up with a custom company domain, and you get a 14-day Enterprise trial.
返金保証: Check the billing terms before you upgrade. With a free-forever plan, most people try before paying anyway.
📌 注記： The free plan supports up to three users and 100 devices. Free users get email support during business hours only.
⚠️ Price check: Some sources list business plans: Starter at $6 per user/month and Premium at $18 per user/month. Starter adds 10 devices per user. Premium adds 20 per user plus priority support. Confirm current prices at checkout.
テールスケールの主な利点
Here’s what makes Tailscale worth a look:
- Direct connections: Each Tailscale client talks to other clients peer to peer over WireGuard. Your network traffic never passes through Tailscale servers.
- No port forwarding: Tailscale works across firewalls using UDP hole punching and NAT traversal. You rarely touch router settings.
- Identity-based access: Access rules follow people, not IP addresses. You can sort users into custom groups with their own permissions.
- MagicDNS: Reach devices by name instead of typing numbers. It makes a tailnet feel like an office network.
- Subnet routers: Reach printers and other gear that can’t run the Tailscale client. One device shares access for the whole subnet.
- 単一障害点が存在しない： The decentralized design eliminates single points of failure. If one path fails, traffic reroutes.
- 自分のペースで成長しよう： Add devices one at a time by sending a link. Your existing setup doesn’t have to change.

AdGuard VPNとは何ですか？
AdGuard VPN is a privacy VPN from AdGuard Software Limited, based in Cyprus.
It hides your real location by routing traffic through a remote server.
Websites see the server’s IP address instead of yours.
The VPN service encrypts your traffic with AES-256 encryption.
Unlike most VPN providers, it runs on a proprietary protocol instead of WireGuard or オープンVPN.
AdGuard puts ad blocking at the heart of its brand, and the VPN follows suit.

AdGuard VPNを検討する価値がある理由は以下のとおりです。
- Built-in ad blocking: Pick AdGuard DNS servers to block ads and trackers. It’s handy if you already use other AdGuard products.

機能比較
Ready to see how Tailscale vs AdGuard VPN compares feature by feature? We’ll walk through 10 areas that matter most when you choose.
| 特徴 | 尾秤 | アドガードVPN |
|---|---|---|
| 開始価格 | 永久無料$0 | 月額2.40ドル（2年間） |
| 無料プラン | ✅ Up to 100 devices | ✅ 3 GB per month |

1. コア目的
尾部スケール: Tailscale builds a private mesh network between your own devices. Think of it as an office network that follows you anywhere. It removes the need for traditional VPN servers, so there’s no central hub.
アドガードVPN: AdGuard VPN is a classic consumer VPN service. It sends your internet traffic through its servers to hide your IP address. You pick a location, connect, and ブラウズ with more online privacy.
⚠️ 警告： Don’t buy Tailscale to watch foreign Netflix or dodge trackers. That’s not its job.
2. Remote Access & Exit Nodes
尾部スケール: This is where Tailscale shines. You can reach a home server or an office computer from any network. Set one machine as an exit node, and your phone’s traffic routes through it.
アドガードVPN: AdGuard VPN doesn’t offer remote access to your own devices. It connects you to AdGuard’s servers, not your computer at home. To reach other devices, you’d need a separate tool.
✅ 知っておくと良いこと： Tailscale lets you invite external users with a simple link. It sends them to the login page, and they join your tailnet.
3. セキュリティと暗号化
尾部スケール: Tailscale uses WireGuard for end-to-end encrypted tunnels. Coordination servers on the control plane only handle key exchange. Data plane traffic flows straight between devices, so Tailscale can’t read it.
The same identity-based rules can also lock down internal AIツール and private models.
アドガードVPN: AdGuard VPN uses AES-256 encryption and its own protocol. The AdGuard VPN protocol masks VPN traffic as normal HTTPS. But it hasn’t been independently audited, which raises transparency concerns.
⚠️ 警告： AdGuard VPN has no third-party audits yet. You’re trusting its security measures on faith.
4. Privacy & Your IP Address
尾部スケール: Tailscale does not hide your IP address from websites by default. Your browsing still exits through your own internet connection. Route traffic through an exit node, and sites see that node’s IP instead.
アドガードVPN: AdGuard VPN hides your real location behind a server IP. Its strict no logs policy says it doesn’t record IP addresses, browsing history, or timestamps. It collects minimal data only to fix technical issues.
For throwaway sign-ups, AdGuard offers a free Temp Mail tool too.
5. 広告とトラッカーのブロック
尾部スケール: Tailscale has no built-in ad blocker. It focuses on connecting devices, not filtering content. You can point your tailnet at your own DNS server if you want filtering.
アドガードVPN: Can AdGuard VPN block ads? Yes, when you pick AdGuard DNS inside the app. In integrated mode, it works alongside the AdGuard ad blocker. The Windows version, マック, and Android apps all support it.
6. スピードとパフォーマンス
尾部スケール: Tailscale connects devices directly, with no hub-and-spoke detour. That cuts lag and boosts throughput compared to traditional VPNs. Site-to-site links between offices work the same way.
アドガードVPN: AdGuard VPN’s performance is fine for browsing and video calls. It isn’t built for data intensive tasks like big downloads or online gaming. Reviewers who tested AdGuard VPN saw about a 20% drop on nearby servers.
Some users report speeds falling from 65 Mbps to around 10 Mbps. Paid plans averaged about 58.73 Mbps in third-party speed tests. Run your own checks on download and upload speed before you commit.
⚠️ 警告： Connection speeds on the free version stay capped. Some users also report random connection drops.
7. Devices, Apps & Ease of Use
尾部スケール: The Tailscale app runs on all major operating systems, plus Apple TV. Creating a tailnet is a short process: sign in through SSO, then install the client. Once installed, new users can connect a second device in minutes.
It also runs on edge and IoT gear without dedicated hardware.
アドガードVPN: AdGuard VPN’s apps cover Windows, macOS, Linux, Android, iOS, and Android TV. The desktop apps look the same on a Windows PC or a MacBook Pro. The mobile apps keep things simple on mobile devices, with one tap to connect.
These easy to use apps suit beginners. The free AdGuard アシスタント browser add-on adds quick page controls.
8. Extra Tools & Settings
尾部スケール: MagicDNS lets you type a device name instead of an IP address. Subnet routers share access to printers or storage boxes that can’t run the client. The web dashboard manages users, devices, and permissions in one place.
アドガードVPN: AdGuard VPN includes a kill switch that kicks in once enabled. Split tunneling lets you choose which apps use the VPN. You can also connect to a US server for one app while others stay local.
💡 プロのヒント: Turn on the kill switch before using ホテル or café networks. It stops leaks if the tunnel drops.
9. Integrations & Cloud Infrastructure
尾部スケール: Tailscale integrates with over 100 technology and identity providers. It connects resources on Google Cloud, other clouds, and on-premises infrastructure into one network. Developers can also read client code and file bugs on GitHub.
Multi-cloud setups work the same way, with no complex configuration.
Teams running containers can add Tailscale inside Kubernetes clusters too.
アドガードVPN: AdGuard VPN doesn’t connect to business tools. Its links stay inside the AdGuard family: the ad blocker, AdGuard DNS, and Temp Mail. That’s enough for personal online security, but not for company networks.
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 | 尾秤 | アドガードVPN |
|---|---|---|
| 無料 | Personal: $0 Free Forever | Free version: 3 GB/month |
| 毎月 | パーソナルプラス：月額5ドル | 1 Month: $11.99/month |
| 年間 | ❌ | 1 Year: $3.99/month |
| Two-Year | ❌ | 2 Years: $2.40/month |
尾部スケール: The free plan does more than many paid tools for personal use. Personal Plus suits households that outgrow it. Business tiers cost more but add priority support.
アドガードVPN: The two-year plan gives you the lowest monthly rate. The monthly plan costs nearly five times as much. The free plan’s 3 GB cap runs out fast if you stream.

よくある質問
Tailscaleは実際にはVPNなのでしょうか？
Yes, but not a typical one. It’s a mesh VPN that connects your own devices directly. Traffic only leaves through another device if you set an exit node.
Tailscaleは私のIPアドレスを隠してくれますか？
Not by default. Websites still see your normal IP address. Route your traffic through an exit node, and they see that device’s IP instead.
AdGuard VPN は安全に使用できますか?
It uses AES-256 encryption, a kill switch, and a strict no-logs policy. The catch: its proprietary protocol hasn’t had a third-party audit yet.
AdGuard VPNは無料ですか？
Yes. The free plan gives you 3 GB of data every month with limited speeds. Paid plans unlock unlimited data and up to 10 devices.
TailscaleでVPNを使用できますか？
Yes, but it can get tricky. Many VPN apps fight over routing on the same device. Split tunneling, or running each tool on separate devices, usually fixes it.
