⚡ 簡単な評価:
- 価格: Avast sells the VPN inside its security bundles, from Free Antivirus up to Premium Security at $49.99/first yr. Mozilla VPN is $4.99/month annually or $9.99/month monthly.
- 最適な用途: Avast SecureLine VPN suits people already using Avast products who want antivirus and a vpn tunnel in one app. Mozilla VPN suits Firefox users who want a standalone vpn.
- 主な違い: Avast VPN runs OpenVPN, WireGuard and its own Mimic protocol on roughly 700 servers. Mozilla VPN runs the wireguard protocol only on Mullvad’s 500+ servers.
- 私たちのおすすめ: Avast VPN, by a narrow 3.7 to 3.5 margin, mostly for its 60 day free trial, 10 device limit and protocol choice.

Avast VPN and Mozilla VPN sit at opposite ends of the same market.
One comes from a security brand you probably know from Avast antivirus.
The other comes from the 非営利 Firefoxブラウザの裏側。
Both hide your ip address and encrypt your internet traffic.
Both also carry real trade-offs that the marketing pages skip.
Here is the honest breakdown before you pay for either vpn service.

Avast VPN とは何ですか?
Avast SecureLine VPN is the virtual private network built by the Avast security team.
It encrypts your connection and hides your ip address behind a vpn tunnel.
The vpn app runs on Windows, Mac, Android, iOS and Android TV.
Avast SecureLine VPN servers number around 700 across 34 countries.
It is built for simplicity across everyday online activities.
Many people first meet it bundled with Avast antivirus rather than as a separate purchase.

Here is a closer look at how the app behaves day to day.

🏆 Winner: Avast VPN
A simple vpn service with a 60 day free trial. Covers one device or ten, on multiple platforms.
アバストVPNの価格
Avast sells the vpn inside its wider security packages. Here is what our data shows for 2026.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 無料アンチウイルス | 無料 | Basic malware cover with no vpn included |
| プレミアムセキュリティ | 初年度49.99ドル | Full device security plus Avast products you already use |
| 究極の | 初年度49.99ドル | Security, cleanup and the SecureLine vpn service together |
Pricing verified September 2026.

無料トライアル: Yes. Avast SecureLine VPN has a 60 day free trial, one of the longest free trials in the category. You must add payment information to start the 60 day trial, and you are not charged until it ends.
返金保証: Avast offers a 30 day refund window on its paid subscriptions.
📌 注記: One subscription covers up to 10 devices at the same time. That is double what Mozilla allows, so a family can install it on every laptop and phone in the house.
⚠️ Pricing conflict: Avast also markets SecureLine on its own at roughly $4.59/month for one year, $4.29/month for two years and $4.39/month for three years, with no monthly plan. Our CSV stores the bundle prices above, so those are the figures used in every table, card and schema here. Check the checkout page before you buy.
Avast VPNの主な利点
Avast SecureLine VPNを検討する価値がある理由は以下のとおりです。
- Smart VPN mode: You set rules so the app can automatically connect on public wi fi or on banking sites. Smart VPN can also switch itself off on a trusted network.
- Protocol choice: It supports the openvpn protocol, WireGuard and the proprietary Mimic protocol. Mimic helps where standard vpn traffic is blocked.
- キルスイッチ: If the vpn connection drops, the kill switch cuts your internet so nothing leaks. It works the same on desktop and mobile.
- Torrenting servers: Avast runs P2P and streaming servers for heavy downloads. These are tuned for speed, so your internet connection avoids bandwidth throttling.
- Public wi-fi cover: Using Avast VPN raises your security on an unsecured public network. That blocks man-in-the-middle attacks at cafes and airports.
- Privacy from trackers: It stops your ISP and advertisers from profiling your browsing data. Masking your location also helps you dodge price discrimination when you shop.

Avast VPNのメリットとデメリット
✅ メリット
- 60 day free trial, longer than most competitors offer
- Connects up to 10 devices on one subscription
- Supports OpenVPN, WireGuard and the Mimic protocol
- Smart VPN mode connects automatically by rule
- Based in the Czech Republic, outside data-sharing alliances

- 遠隔地のサーバーでは速度が急激に低下する
Mozilla VPN とは何ですか?
Mozilla VPN is a standalone vpn from the non-profit behind Firefox.
It launched in 2020 and is built on top of Mullvad VPN’s infrastructure.
The service has more than 500 servers in 30+ countries and sells in 35 countries.
Windows上で動作します。 マック, Linux, Android and iOS, covering up to five devices.
Mozilla markets it as a tool for a free and open internet rather than a bundle add-on.

The video below walks through the app and its main settings.

モジラVPN
A privacy-first vpn service for Firefox users. Audited code, Mullvad’s network, and no activity logs.
Mozilla VPNの料金プラン
Mozilla offers one product and two ways to pay for it.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 年間 | 月額4.99ドル | Long-term users who want the lowest rate |
| 毎月 | 月額9.99ドル | Short trips and month-to-month flexibility |
Pricing verified September 2026.

無料トライアル: None. There is no free version and no trial, which is the biggest gap next to Avast’s 60 day trial.
返金保証: Mozilla VPN offers a 30 day money back guarantee, but only to first time customers.
📌 注記: One subscription covers five devices, and you pick the exact five. Swapping a phone means removing a device from the list first.
⚠️ 警告: The monthly plan at $9.99 is double the annual rate. If you only need a vpn for one trip, budget for that gap before you pick a subscription option.
Mozilla VPNの主な利点
Here is what Mozilla VPN’s feature list actually gives you:
- 独立監査: Cure53 has run independent security audits on the apps and code. That is the clearest difference between the two services here.
- Multi hop routing: Traffic can pass through two different servers instead of one. That adds a layer if you handle sensitive work.
- Firefox integration: Multi account containers let you send different Firefox tabs through separate server locations. No other mainstream vpn does this.
- App exclusions: The split tunneling feature lets you keep chosen apps on your regular internet connection. Banking apps often work better that way.
- Blocking built in: Ad, tracker and malware blocking ship inside the app. It blocks advertisers and trackers from sites like Facebook by hiding your activity.
- No activity logs: The privacy policy states it does not store activity logs, session times or your dns requests. Mozilla does not share data with advertisers or marketers.

機能比較
Here are the ten areas that decide this matchup. The summary table gives you the short answer first.
| 特徴 | アバストVPN | モジラVPN |
|---|---|---|
| 開始価格 | $49.99/first yr bundle | 月額4.99ドル |
| 無料トライアル | ✅ 60日間 | ❌ |
| サーバーネットワーク | 約700人、34カ国 | 30カ国以上で500人以上 |

| マルチホップ | ❌ | ✅ |
| デバイス | 10 | 5 |
| 最適な用途 | Families, Avast antivirus users | Firefoxユーザー、プライバシー重視派 |
1. サーバーネットワーク
アバストVPN: Around 700 servers in 34 countries is small. Many vpns run thousands, so your options for speed and flexibility are limited. Coverage is thin in the Middle East and parts of Asia.

モジラVPN: The server list sits at 500+ servers in 30+ countries, borrowed from マルヴァドVPN. It is smaller again, and the service only sells in 35 countries. Most vpns at this price offer far more server locations.

2. VPNプロトコル
アバストVPN: You get the openvpn protocol, WireGuard and Avast’s own Mimic protocol. Mimic disguises vpn traffic so it looks like normal browsing. That extra option matters on networks that block vpn ports.

モジラVPN: It uses the wireguard protocol exclusively. WireGuard is lean and fast, so the connection is quick to establish. But there is no fallback if a network blocks it.

3. セキュリティ機能
アバストVPN: The kill switch, dns leak protection and webrtc leak protection cover the basics and stop dns leaks. Reviewers note it lacks standout security features beyond that. There is no multi hop option.

モジラVPN: The kill switch is enabled by default, so your internet traffic stops the moment the vpn connection drops. Multi hop sends traffic through two servers. Ad, tracker and malware blocking are included for more security.

⚠️ 警告: Neither app replaces good habits. Keep two-factor on for banking sites even when a vpn tunnel is active.
4. Privacy and Independent Audits
アバストVPN: It records timestamps, data transferred and connection details, but no identifiable activity or ip addresses. The no logs policy has never had an independent audit. In February 2024 the US Federal Trade Commission ordered Avast to pay $16.5 million over a subsidiary, Jumpshot, that sold user data collected through its antivirus without consent.

モジラVPN: Cure53 has run independent audits of the code. Mozilla does not log your online activity, though it does collect your ip address and technical interaction data. Being backed by a non-profit is the ピッチ ここ。

⚠️ 警告: Avast is based in the Czech Republic and sits outside the major data-sharing alliances. That helps, but an unaudited no logs claim is still a claim.
5. 速度とパフォーマンス
アバストVPN: It is a fast vpn close to home, holding a fast connection on nearby servers before dropping sharply on distant ones. Servers are tuned to avoid bandwidth throttling during heavy data activity. Performance is inconsistent rather than bad.

モジラVPN: Published speed tests show download speeds peaking at 360Mbps on Mullvad’s network, which is known for fast speeds. Other stress tests rate it below average against the best vpns. Upload speed is steady enough for calls.
6. ストリーミングサービス
アバストVPN: It can reach Netflix, Disney+ and Amazon Prime Video through its streaming servers. Results are mixed on some catalogues. User reviews flag trouble with Hulu and BBC iPlayer.

モジラVPN: It unblocks ITV, Channel 4 and 9Now but struggles with Netflix and Disney Plus. If geo restricted content is your reason to buy, this is the wrong pick. Prime Video access is unreliable too.

7. Apps and Platforms
アバストVPN: The windows app, Mac client, android app and iOS build are joined by Android TV support. The interface is easy to navigate for beginners. There are no browser extensions.

モジラVPN: Windows, Mac, Linux, the android app and the ios app are all covered. Linux support is the edge over Avast. There is no Android TV build and no browser add-on beyond Firefox containers.

8. Smart Rules and Split Tunneling
アバストVPN: Smart VPN mode is the headline trick. You set rules and the app decides when to automatically connect, such as on a public network or a streaming site. User reviews mention smart vpn rules not firing as expected.

モジラVPN: App exclusions do the same job as split tunneling, letting chosen apps skip the vpn. Multi account containers then route individual Firefox tabs through different servers. Nothing here connects automatically by rule.
9. Devices and Ease of Use
アバストVPN: Ten simultaneous connections cover a household. Install takes a couple of minutes on any operating system. A common complaint is finding it already on a computer after an Avast install.

モジラVPN: Five named devices only, so one device slot has to be freed before you add another. The app is clean and quick to learn. Hardware configuration options are minimal by design.
10. 価格設定とコスト
Here are the plans side by side, straight from our pricing data.
| プラン | アバストVPN | モジラVPN |
|---|---|---|
| 無料プラン | Free Antivirus: Free | ❌ 無料版はありません |
| エントリー料金プラン | プレミアムセキュリティ:初年度49.99ドル | 年間:月額4.99ドル |
| トッププラン | アルティメットプラン:初年度49.99ドル | 月額:9.99ドル/月 |
| 無料トライアル | 60日間無料トライアル | ❌ |
| Refund window | 30日間 | 30 days, first time customers |
アバストVPN: The bundle price buys antivirus, cleanup and the vpn together. If you want only a vpn, you are paying for other services you may not need. The 60 day trial does let you test it fully before any charge.

モジラVPN: Pricing is simple and cheap month for month. Mullvad VPN costs less for the same underlying network, which is the awkward part. You are paying for Mozilla’s brand and Firefox tie-in.
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 |
|---|---|---|
| To test before paying | アバストVPN | 60 day free trial vs none |
| Audited privacy claims | モジラVPN | Cure53 independent audits |
| Cover for a whole family | アバストVPN | 10 devices vs five |
| Firefox tab-level routing | モジラVPN | 複数アカウントコンテナ |
| ストリーミングアクセス | アバストVPN | Reaches Netflix and Prime Video |
| Linuxサポート | モジラVPN | Native Linux client |
| Protocol flexibility | アバストVPN | Mimic protocol bypasses blocks |
💰 あなたの予算
Mozilla’s $4.99/month annual rate looks cheaper until you compare full years against the Avast bundle. Avast also lets you run 60 days before any money leaves your account.
🔌 あなたの技術スタック
If you live in the Firefox browser, Mozilla’s container routing is a real advantage over other vpns. If you already run Avast products, one app for antivirus and vpn is simpler.
📺 あなたのストリーミング習慣
Avast reaches more big platforms, though neither is a streaming specialist. Mozilla users routinely hit blocks on Netflix and Disney Plus.
🎓 あなたの経験レベル
Both apps are beginner friendly with a single big connect button. Avast adds オートメーション through smart rules, which suits people who forget to switch a vpn on.
🆓 無料トライアルとデモ
Only Avast has a trial, and it needs payment information up front. Mozilla asks you to buy first and claim the refund window if it disappoints.
🛟 サポートオプション
Avast support has drawn complaints for unhelpful replies. Mozilla runs email and documentation only, so neither is a strong point.

私たちのレビューで取り上げられなかったこと
We looked at personal and family use, not 仕事 deployments. We did not run long-term stress tests in every region, and coverage in the Middle East deserves its own round. Router setups and dedicated ip options were out of scope. Prices change often, so check both sites first.

🏆 WINNER: AVAST VPN
Avast VPN wins 5 out of 8 categories.
最適な用途: Families sharing one subscription, existing Avast antivirus users, and anyone who wants to try a vpn service free for 60 days.
This is a close call, and the 3.7 to 3.5 gap says so. Avast VPN wins on practical things: devices, protocols, streaming and a trial that costs nothing.
Mozilla VPN’s features point the other way. Audited code, multi hop and a non-profit owner matter if trust is your first filter, and the Jumpshot case is a fair reason to hesitate over Avast.
Mozilla VPN worth buying? Yes, if you are a Firefox loyalist who wants a plain, honest tunnel and nothing else. A good vpn should be easy to trust and easy to run, and if you want more features for the money, Avast is the more complete package, and both are worth a look before you commit to a longer plan.

よくある質問
Avast VPNは本当に効果があるのか?
Yes. It hides your ip address, encrypts traffic and holds a fast connection on nearby servers. Distant server locations slow down noticeably, which is the main complaint.
Avast SecureLine VPNは安全に使用できますか?
The encryption and kill switch are solid, but the no logs policy has no independent audit. The 2024 FTC ruling over past data sales is worth weighing first.
Avast VPNの月額料金はいくらですか?
Our pricing data lists the security bundles at $49.99 for the first year, with a free antivirus tier. Standalone yearly plans are marketed near $4.29 to $4.59 monthly.
Mozilla VPNは信頼できるのか?
It has the strongest trust case here. Cure53 audited the code, the owner is a non-profit, and no activity logs are stored. Your ip address is still collected.
Mozilla VPNはインターネットの速度を低下させますか?
Some slowdown is normal on any vpn. Download speeds have peaked around 360Mbps on Mullvad’s network, though independent tests rate it below average for the price.
