⚡ 簡単な評価:
- 価格: アバスト VPN ships inside suites from $49.99/first yr. Bitdefender VPN suites start at $59.99/yr.
- 最適な用途: Avast SecureLine VPN for a long trial on simple devices. Bitdefender Premium VPN for a bigger network with split tunneling.
- 主な違い： Around 700 servers in 34 countries versus over 4,000 servers in 54 countries.
- 私たちのおすすめ： Bitdefender VPN for most users. It has more server locations, split tunneling, and 24/7 live chat.
The cheaper option here is not the weaker one.
Avast VPN and Bitdefender VPN both come from antivirus companies.
Neither one started life as a standalone virtual private network.
That shows up in the server counts and the privacy paperwork.
One of them carries a $16.5 million FTC settlement on its record.
The other has a vague privacy policy and no Linux support.

機能比較
Both tools do the same basic job. They encrypt your connection and route traffic through a remote server.
The gap shows up in scale, protocol choice, and paperwork. Here are the ten areas that decide it.
| 特徴 | アバストVPN | ビットディフェンダーVPN |
|---|---|---|
| 開始価格 | 初年度49.99ドル | 年間59.99ドル |
| 無料枠 | ✅ Free Antivirus | ✅ 200MB per day |
| サーバー | ~700 | 4,000+ |
| 国々 | 34 | 54 |
| Simultaneous connections | 10 | 10 |
| Kill switch | ✅ | ✅ |
| スプリットトンネリング | ❌ | ✅ |
| Independent audit | ❌ 未発表 | ✅ Reported 2025 |
| Linuxとルーターのサポート | ❌ | ❌ |
| 無料トライアル | ✅ 60日間 | ✅ 7日間 |
| 最適な用途 | Avast Antivirus users | Bitdefender suite users |
1. サーバーネットワークとサーバー設置場所
アバストVPN: Avast SecureLine VPN servers number around 700 across 34 countries. Many vpn providers run five times that. A short server list limits your options for speed and for dodging a busy server location. It is the single biggest constraint here.
ビットディフェンダーVPN: Over 4,000 servers sit in 54 countries, including Europe, North America, and the Middle East. A favorites system pins the server locations you use most, and the app can automatically connect to the nearest one.
2. Speed and Download Speeds
アバストVPN: Performance is inconsistent. Nearby servers hold a fast connection, but distant ones drop hard. Avast does not publish speed tests or stress tests you can check yourself.
ビットディフェンダーVPN: The Catapult Hydra protocol keeps download speeds usable for streaming. Performance dips on long hops to Japan and Australia, where ping times climb. It is not a fast vpn by ノードVPN standards.
⚠️ 警告： Neither vendor publishes raw speed data. Treat any speed claim you read, including ours, as a snapshot of one network on one day.
3．セキュリティ機能と暗号化
アバストVPN: The security features cover the basics. A kill switch handles connection drops, while DNS leak protection and WebRTC leak protection close the common dns leaks. Reviewers note little that sets it apart from other vpn services.
ビットディフェンダーVPN: AES-256 encryption pairs with an automatic kill switch that cuts all internet traffic if the tunnel fails. An ad blocker and anti-tracker filter certain websites. That is more security tooling than Avast ships in the vpn app.
4. Privacy, Logging and Independent Audits
アバストVPN: The no-logs policy has no independent audit behind it. Avast records timestamps, data transferred, and connection details, but says it keeps no identifiable information. It sits in the Czech Republic, outside the data-sharing alliances.
ビットディフェンダーVPN: It keeps no traffic logs and no browsing history, though it does log technical data for fraud prevention. The policy is vague and has no separate VPN section. An independent audit was reported in 2025, but the details are not fully public.
⚠️ 警告： In February 2024 the US Federal Trade Commission ordered Avast to pay $16.5 million for compromising consumer privacy. Its former Jumpshot subsidiary sold user data collected through the antivirus without consent. Bitdefender instead leans on third-party infrastructure from ホットスポットシールド.
5. Protocols and Connection Options
アバストVPN: You get the OpenVPN protocol, WireGuard, and the in-house Mimic protocol. Mimic disguises VPN traffic so it looks like ordinary browsing. That is the one genuine edge Avast holds here.
ビットディフェンダーVPN: WireGuard, OpenVPN, and the catapult hydra protocol all ship in the app. Connection times run a few seconds on a nearby server. Desktop notifications tell you when the vpn connection changes state.
6. Streaming and Geo Restricted Content
アバストVPN: It reaches Netflix, Disney+, and Amazon Prime Video, but results are mixed. Reviews report trouble with Hulu and BBC iPlayer. If Prime Video is your main reason to subscribe, test it during the trial.
ビットディフェンダーVPN: It unblocks BBC iPlayer on a UK server but struggles with Netflix and Disney+. There are no dedicated streaming servers here. Geo restricted content is hit or miss on both tools.
7. Device Support and Multiple Platforms
アバストVPN: It covers Windows, macOS, Android, iOS, and Android TV. The Android TV build stands out, since most vpns in this bracket skip living-room devices. Avast also ships browser extensions through its wider product line.
ビットディフェンダーVPN: App compatibility stops at Windows, macOS, Android, and iOS. No Linux, no routers, no Apple TV or Fire TV Stick. It allows the same number of simultaneous connections as Avast, which is ten.
⚠️ 警告： Bitdefender has no obfuscation, so it does not work in China. Avast’s Mimic protocol is built for that job, though neither vendor guarantees access from restricted regions.
8. Ease of Use and App Experience
アバストVPN: G2 reviews highlight how easy the app is to navigate, especially for beginners. Smart VPN mode is the standout setting, though some reviews report it misfiring. A common complaint is finding it installed without asking for it.
ビットディフェンダーVPN: One tap connects you, and the clean design keeps advanced features out of the way until you want them. Mobile apps match the desktop layout, and the latest version updates through the same dashboard as the antivirus.
9. サポートオプション
アバストVPN: Support is the weakest link. G2 reviews describe the support team as unhelpful on VPN-specific tickets. Self-help articles cover install steps and billing, but little else.
ビットディフェンダーVPN: Live chat runs 24/7, phone support lists numbers by country, and email replies take at least half an hour. A knowledge base carries how-to guides and FAQs. The catch: the general support team handles every Bitdefender product, so you rarely get a VPN specialist.
10. 価格設定とコスト
Here are the plans side by side.
| ティア | アバストVPN | ビットディフェンダーVPN |
|---|---|---|
| 無料 | 無料アンチウイルス | 200MB per day inside a paid suite |
| エントリー料金プラン | Premium Security — $49.99/first yr | Bitdefender Total Security — $59.99/yr |
| 中間計画 | Ultimate — $49.99/first yr | Bitdefender Premium Security — $79.99/yr |
| 上階プラン | ❌ None listed | Bitdefender Ultimate Security — $89.99/yr |
| トッププラン | ❌ None listed | Bitdefender Ultimate Security Plus — $119.99/yr |
アバストVPN: Two paid tiers at the same $49.99 first-year price keeps the choice simple. You are buying a security bundle and the VPN rides along. The 60 day free trial lets you judge it before paying.
ビットディフェンダーVPN: Four tiers scale from basic antivirus up to identity cover. Unlimited VPN starts at the $79.99/yr Premium Security plan. Below that you are on the 200MB daily cap, which will not cover streaming.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| A long test drive | アバストVPN | 60 days versus seven |
| その他のサーバー設置場所 | ビットディフェンダーVPN | 4,000+ against roughly 700 |
| Android TV coverage | アバストVPN | Only one with a TV app |
| スプリットトンネリング | ビットディフェンダーVPN | Avast has no equivalent |
| P2Pファイル共有 | ビットディフェンダーVPN | Allowed on every server |
| A clean privacy record | ビットディフェンダーVPN | No FTC penalty on file |
💰 あなたの予算
Avast opens at $49.99 for the first year against $59.99 for Bitdefender. Many VPNs sold on their own cost less, so only buy a suite if you want the antivirus too.
🔌お使いのデバイス
Both cover multiple platforms, but the edges differ. Avast reaches Android TV, while Bitdefender stops at desktop and mobile apps with no Linux or router option.
🔒 Your Privacy Standards
Neither company publishes the kind of independent audits specialist providers now treat as standard. If online privacy comes first, look past both and at a dedicated vpn provider.
📺 あなたのストリーミング習慣
Bitdefender handles BBC iPlayer well and fumbles Netflix. Avast is the reverse on some accounts, so pick based on the one service you actually watch.
🆓 無料トライアルとデモ
Avast wants payment information before the 60 day free trial starts. Bitdefender gives you seven days and a 30-day refund window, which is tighter but lower commitment.
🛟 サポートオプション
Bitdefender answers on live chat around the clock and by phone. Avast has no comparable channel, and its help articles rarely go past install and billing steps.

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 home users on Windows, Mac, Android, and iOS. We did not measure throughput on congested networks, test either tool from inside a censored country, or evaluate 仕事 licensing. Our notes reflect the September 2026 builds. If you need router-level coverage or an office rollout, neither product was built for that.

🏆 WINNER: BITDEFENDER VPN
Bitdefender VPN wins 5 out of 7 categories.
最適な用途: Existing Bitdefender customers, households wanting one app for security, and anyone who needs split tunneling.
Bitdefender takes it on scale and on paperwork. Six times the servers, split tunneling, P2P everywhere, and support you can actually reach.
Avast keeps two real advantages. The 60 day free trial is the longest here, and Android TV plus the Mimic protocol cover cases Bitdefender ignores.
The FTC settlement decided it for us. A VPN routes everything you do through one company, and that record is hard to set aside.
Bitdefender VPN is a good vpn for casual use and everyday online security. It is not the answer if you want maximum speed or Linux support.
