⚡ 簡単な評価:
- 価格: StrongVPN lists an Annual Plan at $3.97/month. Avast bundles its VPN into Premium Security at $49.99/first yr.
- 最適な用途: Avast VPN suits people already inside Avast products. StrongVPN suits people who want a standalone VPN service with cloud storage.
- 主な違い: Avast SecureLine VPN runs about 700 servers in 34 countries. StrongVPN runs 950+ physical servers in 30 countries and adds 250GB of SugarSync cloud storage.
- 私たちのおすすめ: StrongVPN, by a narrow margin. It covers more devices, allows P2P everywhere, and does not carry Avast’s データ privacy history.

Neither of these is the best VPN on the market.
Both are small, simple services fighting bigger names.
Avast VPN comes bundled with Avast antivirus and sells on convenience.
StrongVPN has been a standalone VPN company since 2005.
One gives you a 60 day free trial. The other gives you 250GB of free cloud storage.
That trade-off decides most of this comparison.

Avast VPN とは何ですか?
Avast VPN is the consumer virtual private network built by Avast.
Its full name is Avast SecureLine VPN.
インターネット接続を暗号化し、IPアドレスを隠します。
Most people use Avast SecureLine VPN because it already sits inside Avast antivirus.
The VPN app runs on Windows, マックAndroid、iOS、およびAndroid TVに対応しています。
One subscription covers 10 devices at once.
Here is the sign-up and support picture in short.

アバストVPN
A simple VPN for everyday browsing and public Wi-Fi. Smart VPN mode can automatically connect on untrusted networks. Ten devices per subscription.
アバストVPNの価格
Avast sells the VPN inside its wider security bundles. Here is what our CSV records for those plans.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 無料アンチウイルス | 無料 | Basic malware cover, no VPN |
| プレミアムセキュリティ | 初年度49.99ドル | Multi-device security on Windows and マック |
| 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. Avast runs a 60 day free trial, one of the longest in the VPN industry. You must enter payment information first, but no charge lands until the 60 day trial ends.
返金保証: Avast offers a 30 day refund window on subscriptions bought directly.
📌 注記: Avast’s own site also lists standalone SecureLine plans at roughly $4.59/month for one year, $4.29/month for two years, and $4.39/month for three years. There is no monthly-only option. Those rates sit outside our CSV, so treat the table above as the billed source of truth.
⚠️ 警告: The first-year price is promotional. Renewal costs more, and the trial auto-converts to a paid plan unless you cancel. Cancel inside the account dashboard, not the desktop app.
Avast VPNの主な利点
Here is what you actually get:
- Smart VPN mode: You set rules so the app can automatically connect on a public network. Handy when you forget to switch it on before banking sites load.
- 60 day free trial: Longer than almost every rival. Free trials at this length are rare.
- Ten device slots: Cover a Windows laptop, phones, tablets, and an アンドロイド TV box on one plan.
- キルスイッチ: Cuts your internet if the VPN connection drops, so your real IP address never leaks mid-session.
- Three protocol choices: Avast supports the OpenVPN protocol, WireGuard, and its own Mimic protocol for restricted networks.
- Czech base: The company sits in the Czech Republic, outside the main data-sharing alliances.

Here are the quick links if you want the deeper write-up.

🏆 Winner: StrongVPN
Twelve device slots, P2P on every server, and 250GB of free cloud storage. Simple apps and a 30 day money back guarantee on the annual plan.
StrongVPNの料金プラン
StrongVPN keeps its pricing to two plans. Here is our CSV record.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 年間計画 | 月額3.97ドル | Long-term users who want the refund window |
| 月額プラン | 月額11.99ドル | Travellers and short-term testing |
Pricing verified September 2026.

無料トライアル: None. StrongVPN has no free version and no trial period, which is a real gap next to Avast.
返金保証: 30 days on the annual plan. Monthly buyers get no refund window.
📌 注記: Payment options include credit cards, PayPal, and Alipay. There is no 暗号 route, so your payment information is always tied to a named account.
⚠️ 警告: Year one is the cheap year. StrongVPN’s public pricing page shows the annual rate rising sharply at renewal, and some public sources list the monthly plan at $10.99 rather than the $11.99 in our CSV. Diarise the renewal date.
StrongVPNの主なメリット
Here is where your money goes:
- Twelve device slots: Two more than Avast. The devices StrongVPN supports include mobile devices, desktops, and Fire TV sticks.
- 250GB free cloud storage: The SugarSync bundle is the only cloud storage perk in this price bracket.
- Physical servers only: StrongVPN does not use virtual server locations, so a Tokyo server really sits in Tokyo.
- StrongDNS included: The SmartDNS tool changes your virtual location without encryption, so there is no speed cost for streaming platforms.
- P2P everywhere: Every server allows P2P transfers, so you never hunt for dedicated torrenting servers.
- Protocol range: WireGuard, OpenVPN, IKEv2, SSTP, and L2TP, plus manual setup guides for odd devices.

機能比較
Both are mid-tier VPN services, so the gaps are narrow. Here are the ten areas that actually change your day-to-day use.
| 特徴 | アバストVPN | 強力なVPN |
|---|---|---|
| Entry price (CSV) | $49.99/first yr bundle | $3.97/month annual |
| 無料トライアル | ✅ 60日間 | ❌ なし |
| Server network | 約700人、34カ国 | 30か国で950以上 |
| Simultaneous connections | 10 | 12 |
| Kill switch | ✅ | ✅ |
| スプリットトンネリング | ✅ Android | ✅ Android |
| Browser extensions | ❌ | ❌ |
| Cloud storage bonus | ❌ | ✅ 250GB SugarSync |
| Independent audit | ❌ | ❌ |
| 最適な用途 | 既存のAvastユーザー | 多数のデバイスを所有する家庭 |
1. サーバーネットワーク
アバストVPN: Avast SecureLine VPN servers number around 700 across 34 countries. That country count is the wider of the two, but the raw total is small. Many VPNs run five or ten times as many boxes, which limits your options when one location gets busy.
強力なVPN: 950+ servers in 30 countries, all physical servers rather than rented virtual entries. Coverage across Europe, North America, and Asia is fine. Coverage in Africa and the Middle East is thin on both services, and both networks stay small next to most VPNs.
2. 速度とパフォーマンス
アバストVPN: Published speed tests show good results nearby and steep drops on distant hops. That pattern makes it a fast VPN inside your own region and a slow one across continents. Pick the closest server and it holds up.
強力なVPN: Download speed retention on nearby servers shows only a 5-7% speed loss, though wider samples put the average drop nearer 20%. Upload speeds fall harder than download speeds. Latency runs higher than top-tier rivals, so competitive gaming is not its strength.
⚠️ 警告: Neither brand publishes repeatable stress tests. Treat every speed figure here, ours included, as a snapshot on one internet connection rather than a guarantee.
3. ストリーミングアクセス
アバストVPN: Netflix, Disney+, and Amazon Prime Video usually work. Results with Hulu and BBC iPlayer are mixed. G2 reviewers flag blocks that clear only after a location change.
強力なVPN: It reaches major streaming platforms with minimal buffering, and StrongDNS is the backup when the VPN tunnel itself gets blocked. Prime Video and Netflix are the reliable pair here.
4. セキュリティ機能
アバストVPN: AES-256 encryption, a kill switch that fires when the connection drops, plus DNS leak protection. Smart VPN mode is the standout security feature, since rules can trigger the tunnel on any public network you flag as risky.

強力なVPN: The same strong encryption standard, a kill switch, DNS leak protection, and WebRTC leak protection. Independent leak tests published by reviewers found no DNS leaks. We strongly advise leaving the kill switch on if you want more security on shared networks.

5. VPNプロトコル
アバストVPN: Three choices. The OpenVPN protocol for compatibility, WireGuard for speed, and the proprietary Mimic protocol, which disguises VPN traffic where connections are filtered.
強力なVPN: Five choices. WireGuard, OpenVPN, IKEv2, SSTP, and L2TP, all switchable from the settings menu. SSTP and L2TP matter mainly for older hardware, but the breadth beats Avast on paper.

6. プライバシーとログ記録
アバストVPN: The no-logs policy records timestamps, data transferred, and connection details, but not identifiable browsing data. No independent audit backs it. The bigger issue is history: Avast’s Jumpshot subsidiary sold user data without consent, and the FTC ordered a $16.5 million payment in February 2024.

強力なVPN: It advertises a strict no logging policy covering browsing history, browsing activity, timestamps, and IP addresses. The only personal information collected is billing details and an email address. StrongVPN claims it never sells user data, but no independent audits confirm any of it, and the US base sits inside the Five Eyes alliance.

⚠️ 警告: Both brands make strict no logging policies a selling point, and neither has proof. If an audited log policy is your deal-breaker, look at the best VPNs from Panama or Switzerland instead.
7. Apps and Platforms
アバストVPN: The Windows app, Mac, iOS, and the Android app all exist, and Android TV support is a genuine edge for living-room setups. The Android app is on the Google Play Store under the SecureLine name, so search carefully.
強力なVPN: Native apps across multiple platforms, including Chrome OS and Amazon Fire TV, plus router setup guides. Mobile apps mirror the desktop layout closely, and the Android apps behave the same across phones and other Android devices. Neither service ships browser extensions, so a Chrome-only user loses out with either pick.
8. Devices and Extras
アバストVPN: Ten device slots with no bandwidth usage cap. Extras stay inside the Avast family, such as AntiTrack and cleanup tools bundled into the higher plan.
強力なVPN: Twelve slots plus 250GB of SugarSync cloud storage. Beyond that, StrongVPN features stay lean: no ad blocker, no パスワードマネージャー, no breach alerts. If you were paying for cloud storage anyway, that bundle changes the maths. Start on one device, add the rest later.
9. Torrenting and Split Tunneling
アバストVPN: P2P is limited to specific torrenting servers, so you must pick the right location before you start a download. Split tunneling is Android only.
強力なVPN: P2P runs on every server, which is simpler. Both services offer split tunneling on Android only, so Windows users who need banking sites outside the tunnel are stuck either way.
10. 価格設定とコスト
Here are the CSV plans side by side.
| プラン | アバストVPN | 強力なVPN |
|---|---|---|
| 無料プラン | Free Antivirus: Free | ❌ |
| 毎月 | ❌ 提供されていません | 月額11.99ドル |
| 年間 | プレミアムセキュリティ:初年度49.99ドル | 月額3.97ドル |
| 最高級 | アルティメットプラン:初年度49.99ドル | ❌ |
アバストVPN: The value case depends on whether you want the rest of the bundle. Paying $49.99 for the first year makes sense if you also use the antivirus, the cleanup tools, and AntiTrack. Paying it for the VPN alone does not.
強力なVPN: $3.97/month on the annual plan is competitive for a standalone VPN with 12 slots and cloud storage. The monthly plan at $11.99 is poor value and exists mostly for short trips.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| To test before paying | アバストVPN | 60 day trial vs none |
| More device slots | 強力なVPN | 12対10の接続 |
| Easy torrenting | 強力なVPN | すべてのサーバーでP2P接続が可能 |
| Android TV coverage | アバストVPN | Dedicated TV app |
| Cloud storage bundled | 強力なVPN | SugarSync 250GB付属 |
| One security bill | アバストVPN | VPN plus antivirus in one plan |
💰 あなたの予算
StrongVPN’s annual plan is the cheaper way to buy a VPN on its own, though other VPNs undercut it on multi-year deals. Avast only looks cheap if you were already buying the security bundle.
🔌 あなたの技術スタック
Running Avast products already? The VPN sits one click away inside software you have installed. Running a mixed house of mobile devices and a Fire TV? StrongVPN covers more of it.
📝 毎日の使用
For casual browsing and public Wi-Fi, either is fine. For steady downloads and streaming across several screens, StrongVPN handles online activities with less fuss.
🎓 あなたの経験レベル
Avast’s app is the friendlier first VPN, with a two-click connect and almost nothing to configure. StrongVPN asks slightly more of you but hides little.
🆓 無料トライアルとデモ
Only one side has a trial. Avast’s 60 days lets you test the VPN tunnel on your own connection before spending. StrongVPN gives you a 30 day money back guarantee instead.
🛟 サポートオプション
StrongVPN offers live chat, phone, and email. Avast support has drawn complaints from other users for slow, generic replies, which matters when a VPN connection fails mid-trip.

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 households. We did not run leak tests on every server location, and we did not measure either service from China, Iran, or other heavily filtered networks. 仕事 licensing, router-level deployment, and long-term renewal pricing sit outside what we checked. If you need a VPN for censorship circumvention rather than online privacy, your priorities will differ from ours.

🏆 WINNER: STRONGVPN
StrongVPN wins 5 of 7 categories.
最適な用途: Multi-device households, torrenting, streaming, and anyone who wants cloud storage bundled in.
The gap here is small, and it is not really about features. Both are simple, unaudited, mid-tier services that do the basics. Either keeps you safe online for ordinary browsing, and neither can prove what it does with your online activity.
StrongVPN wins because it is a VPN company first. You get more servers, more device slots, P2P anywhere, and a cloud storage bundle nobody else throws in at this price.
Avast VPN wins on one thing that matters to cautious buyers: you can test it for 60 days for free. If you are already inside the Avast world, that convenience is real.
But the 2024 FTC penalty is hard to ignore when the product you are buying is privacy. For most people, StrongVPN is the safer bet.

よくある質問
Avast SecureLine VPNは安全に使用できますか?
It uses AES-256 encryption, a kill switch, and DNS leak protection. But the no-logs policy has never passed an independent audit, and the parent company paid a $16.5 million FTC penalty in 2024.
Avastには無料のVPNサービスがありますか?
No permanent free version exists. You get a 60 day free trial, which needs payment information upfront and converts to a paid plan automatically unless you cancel first.
StrongVPNは無料ですか?
No. There is no free version and no trial. The annual plan includes a 30 day money back guarantee, so that refund window is your only risk-free test.
StrongVPNには何台のデバイスを接続できますか?
Twelve at once on a single account. That covers laptops, phones, tablets, and streaming sticks. Avast VPN caps you at ten, so the difference is two extra slots.
Avast VPNは信頼できるのか?
The Czech base helps, and connection logs exclude identifiable details. The Jumpshot data-selling scandal and the missing audit still give privacy-focused buyers a reason to hesitate.
