One of these tools is a virtual private network bolted onto an antivirus brand.
The other is a VPN tunnel bolted onto an ad blocker.
Neither is trying to beat the best VPNs on raw speed.
Both want to be the easy second layer on your internet connection.

Avast VPN とは何ですか?
Avast SecureLine VPN is the virtual private network built by the Avast antivirus company.
It hides your real IP address and encrypts your traffic through a remote server.
Avast SecureLine VPN servers number around 700 across 34 countries.
You can use Avast SecureLine VPN on Windows, Mac, アンドロイド, iOS and Android TV.
Avast is based in the Czech Republic, outside the main data-sharing alliances.
Here is how the service behaves day to day.
アバストVPN
Avast SecureLine VPN covers up to 10 devices on one subscription. It supports OpenVPN, WireGuard and the Mimic protocol. Smart VPN mode can automatically connect on public wi fi.
アバストVPNの価格
Here is what Avast products cost in 2026. Let’s break it down.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 無料アンチウイルス | 無料 | Basic protection on one device |
| プレミアムセキュリティ | 初年度49.99ドル | Multi-device security on multiple platforms |
| 究極の | 初年度49.99ドル | Security plus VPN and cleanup tools |
Pricing verified September 2026.
無料トライアル: Yes — a 60 day free trial, among the longest free trials in the category. Payment information is required first, but nothing is charged until the 60 day trial ends.
返金保証: A 30 day money back guarantee covers paid subscriptions. Cancel inside that window for a refund.
📌 注記： The table lists the Avast product plans in our データ sheet. The VPN ships inside Ultimate and is also sold on its own.
⚠️ Pricing conflict flagged: Standalone yearly plans are quoted elsewhere at $4.59 (one year), $4.29 (two years) and $4.39 (three years) per month. There is no month-to-month option. Our tables keep the data sheet figures, so check the cart before you buy.
Avast VPNの主な利点
Here is what makes Avast SecureLine VPN worth considering:
- Long Free Trial: 60 days beats most vpn providers. You get a real test window, not a weekend.
- Three Protocols: OpenVPN, WireGuard and the in-house Mimic protocol. Mimic helps a vpn connection slip past networks that block VPN traffic.
- スマートVPNモード: Set rules so the app can automatically connect on a public network. Smart VPN can stay off for banking sites you trust.
- Kill Switch and Leak Cover: The kill switch cuts the internet if the tunnel drops. DNS leak protection and WebRTC leak protection stop dns leaks exposing your real location. Both add more security on shared lines.
- ストリーミングとトレント: Streaming servers and torrenting servers are labelled in the app. Netflix, Disney+ and Amazon Prime Video usually load.
- Ten Devices: One subscription covers 10 devices, so you are not stuck on one device. Servers are tuned to avoid throttling on heavy download sessions.
- Everyday Privacy: Your ISP and advertisers lose sight of your browsing data. On public wi fi networks that layer of online privacy blocks man-in-the-middle snooping. Masking location also helps you dodge price changes based on where you shop from.

AdGuard VPNとは何ですか？
AdGuard VPN is the privacy tool made by AdGuard Software Limited in Cyprus.
It routes traffic through a remote server and hides your online identity.
The network covers 65+ server locations across 53 countries.
Cyprus sits outside the 5/9/14 Eyes alliances and follows GDPR rules.
The company is best known for the AdGuard ad blocker and AdGuard DNS.
One AdGuard VPN app covers desktop and mobile from a single login.
The video below walks through the app.
アドガードVPN
AdGuard VPN pairs AES-256 encryption with a free version capped at 3 GB a month. Paid plans allow 10 simultaneous connections. DNS servers can block ads at the same time.
AdGuard VPNの価格
2026年におけるAdGuard VPNのサブスクリプション料金は以下の通りです。
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 1ヶ月 | 月額11.99ドル | Short trips and quick tests |
| 1年 | 月額3.99ドル | Steady use with real savings |
| 2年 | 月額2.40ドル | 最も安価な長期オプション |
Pricing verified September 2026.
無料トライアル: No timed trial. The free plan gives you 3 GB of data every month with no payment details needed.
返金保証: A 30 day money back guarantee covers the yearly and two-year plans, so you can buy AdGuard VPN risk free.
📌 注記： AdGuard takes cards, PayPal and 暗号. One AdGuard account unlocks all the features across AdGuard products, so the VPN and the ad blocker share a login.
⚠️ 警告： The two-year rate is sometimes listed as $119 up front, closer to $2.99 a month. Our table keeps the $2.40 data sheet figure. Confirm the total at checkout.
AdGuard VPNの主なメリット
AdGuard VPNを検討する価値がある理由は以下のとおりです。
- 本当の無料プラン： 3 GB every month costs nothing. Fine for light browsing, though the free version caps you at 20 Mbps.
- Ads Blocked at the DNS Level: Use AdGuard VPN with its own DNS servers and the vpn block ads behaviour works system-wide. That covers apps, not just the browser.
- Traffic That Looks Normal: The AdGuard VPN protocol masks the vpn tunnel as regular HTTPS. That helps on networks that filter certain websites.
- スプリットトンネリング: Pick which apps or sites skip the tunnel. Handy when a banking app refuses to load over a VPN.
- 幅広いデバイスのサポート: Desktop apps for Windows and macOS, mobile apps for Android and iOS, plus Android TV, Linux and browser extensions for Chrome, Firefox and Edge. AdGuard VPN’s apps keep the same layout everywhere.
- Privacy on Paper: A strict no logs policy, no IP logging, no connection timestamps. AdGuard puts its Cyprus base forward as the reason.
- Ten Connections: Paid plans allow 10 simultaneous connections. AdGuard offers an integrated mode on Windows so the VPN and ad blocker cooperate instead of fighting.

機能比較
Let’s compare Avast VPN and AdGuard VPN across 10 areas that decide most buying calls.
| 特徴 | アバストVPN | アドガードVPN |
|---|---|---|
| 開始価格 | Free (antivirus tier) | 月額2.40ドル |
| 無料プラン | ❌ (60 day trial) | ✅（月間3GB） |
| サーバーネットワーク | 約700人、34カ国 | 65か所に800人以上 |
| 同時接続 | 10 | 10 |
| OpenVPN / WireGuard | ✅ | ❌ |
| キルスイッチ | ✅ | ✅ |
| スプリットトンネリング | ✅ | ✅ |
| 内蔵広告ブロッカー | ❌ | ✅ (DNS level) |
| 独立監査 | ❌ | ❌ |
| 最適な用途 | Avast antivirus users, streaming | Blocking ads, light browsing |
1. サーバーネットワークと場所
アバストVPN: Avast SecureLine VPN servers sit at roughly 700 machines in 34 countries. That is small next to most VPNs and limits your exit points. Coverage in regions like the Middle East is thin.
アドガードVPN: Around 800 servers spread over 65+ server locations in 53 countries. Wider on paper, but the free tier opens a few server locations only. Many VPNs at this price run ten times the network.
2. Protocols & Encryption
アバストVPN: You get the OpenVPN protocol, WireGuard and the in-house Mimic protocol. Mimic disguises the vpn tunnel so restrictive networks let it through. Open, widely reviewed options are the bigger win.
アドガードVPN: AES-256 encryption protects your data, but the AdGuard VPN protocol is proprietary and stands alone. It hides VPN traffic as HTTPS. No OpenVPN, no WireGuard, and no outside review of the code.
⚠️ 警告： A single closed protocol is the main transparency gap for AdGuard VPN. If open standards matter to you, this is the deciding line.
3. Ad Blocking & DNS
アバストVPN: There is no ad blocker inside the VPN. Blocking ads means adding AntiTrack or a browser tool from the wider Avast products range, which is a second purchase.
アドガードVPN: This is the home turf. Pick AdGuard DNS servers in the app and it will block ads and trackers before they load. Pair it with the AdGuard ad blocker and coverage reaches every app.
4. Privacy, Logs & Audits
アバストVPN: The no logs policy allows timestamps, data volume and connection details, but not identifiable browsing data. There has never been an independent audit. Avast also carries history: its Jumpshot arm sold user data, and in February 2024 the FTC ordered a $16.5 million payment over privacy failures.
アドガードVPN: A strict no logs policy that skips IP addresses, browsing history and connection timestamps. Only basic diagnostics are collected. There is no third-party audit here either, so both ask you to trust the policy 文章.
⚠️ Neither passes here. No independent audits exist for either service. That gap is common across the category, but premium VPNs like NordVPN and エクスプレスVPN publish audit reports.
5. スピードとパフォーマンス
アバストVPN: Reports point to a fast connection nearby and a sharp fall on distant servers. A US server should hold up for video calls.
アドガードVPN: AdGuard VPN’s performance sits below average in most speed tests. Reviewers who tested AdGuard VPN saw a 65 Mbps line fall near 10 Mbps at worst, with paid-tier averages near 58.73 Mbps. Connection drops are also reported.
💡 プロのヒント: The free version caps you near 20 Mbps. That is enough to browse, not enough for online gaming, large downloads or other data intensive tasks. Upload speed suffers first.
6. ストリーミングとブロック解除
アバストVPN: Servers tuned for streaming are labelled in the app, and Netflix, Disney+ and Amazon Prime Video usually open. Results are mixed on Hulu and BBC iPlayer. Separate torrenting servers are marked for P2P.
アドガードVPN: Netflix, Disney+ and BBC iPlayer generally work. Amazon Prime and Peacock often refuse. Expect buffering on some streaming platforms, especially outside the paid tier.
7. アプリとプラットフォームのサポート
アバストVPN: The Windows app, マック build, Android app, iOS release and Android TV version cover the usual ground. It is easy to install and suits beginners. There are no browser extensions for the VPN.
アドガードVPN: Windows, macOS, Android, iOS, Android TV and Linux, plus browser extensions for Chrome, Firefox and Edge. On a Windows PC the windows version can run in integrated mode alongside the ad blocker. Mobile devices get the same clean interface.
8. Security Features & Extras
アバストVPN: Kill switch, DNS leak protection, WebRTC leak protection and split tunneling are all present. Smart VPN mode is the standout: rules tell the app to automatically connect on a public network and stay off trusted banking sites. Reviewers say the rules occasionally misfire.
アドガードVPN: Kill switch and split tunneling cover the basics, and custom DNS server choice adds to your online security. Beyond those security measures the feature list is thin. Reviewers regularly flag the lack of standout extras.
9. カスタマーサポート
アバストVPN: Phone, email and a large help centre back the paid plans. Reviews are split, and some buyers call the support team unhelpful on billing questions.
アドガードVPN: No 24/7 live chat. Help runs through a ticketing system and email, slower than most vpn providers at this price.
10. 価格設定とコスト
プランを並べて比較してみましょう。
| プラン | アバストVPN | アドガードVPN |
|---|---|---|
| 無料プラン | 無料アンチウイルス | 3 GB/month free plan |
| 1ヶ月 | ❌ 提供されていません | 月額11.99ドル |
| 1年 | 初年度料金：49.99ドル（プレミアムセキュリティ） | 月額3.99ドル |
| 最高級 | 初年度料金：49.99ドル（アルティメットプラン） | 月額2.40ドル（2年間） |
アバストVPN: Ultimate bundles the VPN with security and cleanup tools for one first-year fee. If you already pay for Avast antivirus, the VPN is close to free. If you only want a tunnel, you pay for extras you will not open.
アドガードVPN: The two-year rate is the cheapest number on this page. The monthly rate at $11.99 is the expensive way in. Both buy fewer servers and fewer security features than the price suggests.
さまざまなシナリオ
| もしあなたが…を必要とするなら… | 選ぶ | なぜ |
|---|---|---|
| 最も安い長期プラン | アドガードVPN | $2.40/month on two years |
| A free tier with no card | アドガードVPN | 3 GB every month |
| OpenVPN or WireGuard | アバストVPN | AdGuard runs one closed protocol |
| Streaming Prime Video | アバストVPN | Labelled streaming servers |
| 広告ブロック機能が組み込まれています | アドガードVPN | DNS-level blocking |
| A long test before paying | アバストVPN | 60 day trial |
💰 あなたの予算
AdGuard VPN is cheaper over two years at $2.40 a month. Avast asks $49.99 for the first bundle year, which only pays off if you want the antivirus too.
🔌 あなたの技術スタック
Already running Avast antivirus? The VPN slots into the same dashboard. Already using the AdGuard ad blocker? One AdGuard account covers both, and integrated mode keeps them out of each other’s way.
📺 あなたのストリーミング習慣
Avast is the safer pick for Netflix and Prime Video thanks to labelled streaming servers. AdGuard VPN handles BBC iPlayer well but stumbles on Amazon Prime.
🎓 あなたの経験レベル
Both apps are built for beginners and take two minutes to install and connect. Neither buries you in configuration screens.
🆓 無料トライアルとデモ
Avast gives you a 60 day free trial but wants payment information up front. AdGuard’s free plan never asks for a card, so it is the lower-commitment way to test.
🛟 サポートオプション
Avast has phone and email routes, though customer support reviews are mixed. AdGuard runs tickets only, so plan for a wait.

私たちのレビューで取り上げられなかったこと
This comparison looked at individual users and small households. We did not measure router setups, obfuscated servers in censored regions, or long-haul speed tests. 仕事 licensing and bulk device management sat outside our scope. Our notes reflect the September 2026 builds, and pricing pages change often. If you need a VPN for daily torrenting or competitive online gaming, weigh those needs separately.

🏆 WINNER: AVAST VPN
Avast VPN takes 4 of 8 categories and edges ahead on rating, 3.7 against 3.4.
最適な用途: Existing Avast customers, streaming on 10 devices, and anyone who wants a real protocol choice.
These two are close, and the winner depends on what you already own. Avast SecureLine VPN gives you three protocols, a 60 day trial and servers labelled for streaming and torrenting. That is the fuller package for everyday online activities.
AdGuard VPN answers a narrower question well. It costs less over two years, blocks ads at the DNS level, and carries no FTC settlement. If ad blocking is the point and speed is secondary, it earns its place.
Neither is a fast VPN by 2026 standards, and neither has an independent audit. A good VPN choice here comes down to range against price. Pick Avast for range, pick AdGuard for cost and clean pages.
