Azneem Bilwani started the VPN company in 2016.
It hides your VPN IP address and encrypts your internet connection.
The network has around 800 servers in 49 countries.
FastestVPNはケイマン諸島に拠点を置いています。
That territory has no mandatory データ 保持法。
It also sits outside the major international surveillance alliances.
Despite the name, it isn’t the fastest VPN on the market.

| 1ヶ月プラン | 月額5ドル | 短距離旅行またはテスト |
| 限定生涯プラン | $40 | One payment, no renewals |
Pricing verified October 2026.

返金保証: Every plan comes with a 31-day money back guarantee.
📌 注記： Add-ons cost extra. A dedicated IP address is $1.49/month. Port forwarding is $1.20/month. Up to 10 extra connections cost $4 each per month.
⚠️ Price check: Some review sites list the yearly FastestVPN subscription at $19.95, about $1.66/month. That charge also covers the free bonus year. Spread over two years, it lands at $0.83/mo. Confirm the total at checkout.
⚠️ 警告： “Lifetime” means the life of the company, not yours. Even so, two or three years of use covers the $40 cost.

Here’s what FastestVPN offers for the money:
- Low Long-Term Cost: The lifetime plan is a single $40 payment. Few VPN providers offer anything like it.

機能比較
Let’s put FastestVPN and AdGuard VPN side by side. We’ll cover 10 areas that matter most for everyday users.
| 特徴 | 最速VPN | アドガードVPN |
|---|---|---|
| 開始価格 | 月額0.83ドル | 月額2.40ドル |
| 無料プラン | ❌ | ✅ 月間3GB |
| 生涯プラン | ✅ 40ドル | ❌ |

| 最適な用途 | Budget privacy and streaming | Ad blocking and light browsing |
1. Server Network & Speed
最速VPN: The service runs around 800 servers in 49 countries. With so few servers, peak hours can feel crowded. Independent speed tests clocked nearby servers at around 730 Mbps on WireGuard.
Average download speeds fell about 45% in those tests. Long-distance servers lost up to 55%. Upload speed dropped about 22% on one machine. Ping didn’t change on one computer but rose 33% on another.
アドガードVPN: Its server list reaches more countries, but AdGuard VPN’s performance trails on speed. One review saw speeds fall from 65 Mbps to about 10 Mbps. Paid servers averaged around 58.73 Mbps in another test.
Nearby servers lost about 20% on average. Some users also report connection drops. Neither tool suits online gaming or video calls on distant servers.
💡 プロのヒント: Choose a server location close to you. Both tools show slow speeds on long hops. Your base internet speed also sets the ceiling.
2. VPNプロトコル
最速VPN: You can pick WireGuard, OpenVPN TCP, or IKEv2. An Auto mode chooses for you. The WireGuard protocol gives the best speed.
アドガードVPN: It uses only a proprietary protocol. Traffic looks like normal HTTPS, which helps bypass censorship. But there’s no WireGuard or OpenVPN, and the protocol hasn’t been independently audited.
⚠️ 警告： Does AdGuard VPN work in China? Several reviews say it struggles with the Great Firewall. ExpressVPN and ノードVPN handle it better.
3. Kill Switch & Leak Protection
最速VPN: The kill switch cuts your internet if the VPN connection drops. That prevents data leaks. Some reviews 質問 its reliability, so test it once.
アドガードVPN: A kill switch is included here too. It blocks traffic if the VPN tunnel fails. Its policy says it never logs IP addresses or browsing history.
FastestVPN also adds DNS leak protection. FastestVPN’s servers handle all DNS requests, so DNS queries stay hidden from your ISP.
⚠️ 警告： Some reviews report DNS leaks and IP leaks in the Windows version. Run DNS leak tests right after you install FastestVPN.
4. Ad Blocking & DNS Filtering
最速VPN: The built-in ad blocker removes most ads and adds basic malware protection. It isn’t antivirus software, though. Treat it as a handy extra.
アドガードVPN: This is home turf. Can AdGuard VPN block ads better? Yes, by a wide margin. Integrated mode runs the full ad blocker and VPN together.
AdGuard DNS adds filtering at the DNS server level. You can pick DNS servers that stop trackers before pages load. Set it on a router to cover every device.
5. Split Tunneling vs Smart Tunneling
最速VPN: Split tunneling works on Windows and for Android users. Smart Tunneling goes further. It sends chosen browser traffic through the VPN, even before you connect.
アドガードVPN: Its split tunneling feature is called Exclusions. You choose which apps or certain websites skip the VPN. It works across desktop apps and mobile apps.
6. Devices & Simultaneous Connections
最速VPN: FastestVPN’s apps run on Windows, マック, Android, iOS, and Linux. The FastestVPN iOS app works on iPhone and iPad. Router setup also covers Apple TV.
FastestVPN apps allow 10 simultaneous connections per account. The Windows app and Mac apps share a clean, beginner-friendly design.
アドガードVPN: AdGuard VPN’s apps cover Windows, macOS, Android, iOS, Android TV, and Linux. The AdGuard VPN app is clean on mobile デバイス. Paid plans also cover 10 devices.
AdGuard アシスタント extension adds one-click page filtering in your browser.
7. Streaming & Torrenting
最速VPN: It has dedicated streaming servers and a streaming tab in the app. It works with Netflix, Disney+, Hulu, Hotstar, Amazon Prime Video, and BBC iPlayer. US, UK, 日本, and Sweden Netflix libraries unblock.
The streaming FastestVPN offers isn’t perfect. US Netflix loaded slowly in some reports. The Australian library didn’t work. All FastestVPN servers allow torrenting, but torrent speeds are reported as slow. Every plan includes unlimited bandwidth.
アドガードVPN: Connect to a US server, and Netflix, Disney+, and BBC iPlayer usually work. It struggles with Amazon Prime and Peacock on other streaming platforms. Buffering and long load times show up in reviews.
✅ 結果: FastestVPN unblocks more streaming services and Netflix libraries. That makes it the safer pick for streaming sites.
8. Privacy & Security Extras
最速VPN: Its no-logs rule was confirmed by a third-party audit from Altius IT. AES-256 encryption and a NAT firewall add layers. Dedicated IPs and double VPN servers are optional extras.
アドガードVPN: It also uses AES-256 and a strict no logs policy. It collects minimal technical data to fix bugs. But it has never had a third-party audit.
Your AdGuard account also unlocks Temp Mail. It gives you throwaway addresses for sites you don’t trust.
9. カスタマーサポート
最速VPN: Live chat runs 24/7, plus email support. Replies come fast, but answers can feel generic. Trustpilot reviews often praise the support, while others call it unhelpful.
アドガードVPN: There’s no 24/7 customer support or live chat. You reach the support team through a ticketing system. Help articles fill some gaps.
💡 プロのヒント: FastestVPN’s knowledge base has setup guides, but its search is weak. Browse by category instead.
10. 価格設定とコスト
Here are both price lists side by side.
| プラン | 最速VPN | アドガードVPN |
|---|---|---|
| 無料 | ❌ | 3 GB/month free plan |
| 毎月 | 1 Month Plan: $5/mo | 1 Month: $11.99/month |
| 年間 | 1 Year + 1 Year Free: $0.83/mo | 1 Year: $3.99/month |
| Long Term | Exclusive Lifetime Plan: $40 | 2 Years: $2.40/month |
| 返金期間 | 31 days, all plans | 30 days, yearly and 2-year |
最速VPN: The 2-year deal and lifetime plan are hard to beat. Add-ons like a dedicated IP raise the total. Skip the monthly plan unless you need a short trial.
アドガードVPN: Monthly billing is pricey at more than double FastestVPN’s rate. The free plan is the real draw. Light users may never need to pay.
さまざまなシナリオ

最適な用途: Budget buyers, streamers, and users who want audited privacy
FastestVPN and AdGuard VPN solve different problems. One is a budget VPN with audited privacy. The other is an ad-blocking company’s take on a VPN.
AdGuard VPN makes sense if blocking ads matters most. It isn’t the best VPN for speed. Its free plan still suits light browsing and online privacy on the go.
For most people, FastestVPN is the better buy. You get open protocols, live help, and lower long-term costs. When testing FastestVPN, start with a nearby server for the best speed.
