⚡ 簡単な評価:
- 価格: アドガード VPN runs $11.99/month, or $2.40/month on the 2 Years plan. Bitdefender VPN ships inside security suites from $59.99/yr.
- 最適な用途: Bitdefender VPN suits people who already own a Bitdefender product. AdGuard VPN suits people who want ad blocking and a cheap long plan.
- 主な違い： Bitdefender runs 4,000+ servers in 54 countries. AdGuard covers 65+ server locations across 53 countries and adds Linux, Android TV and browser extensions.
- 私たちのおすすめ： AdGuard VPN for most buyers, because the free version lets you test the apps before you pay.
The cheaper VPN here is not the one from the smaller company.
Bitdefender VPN is sold inside a security suite you buy once a year.
AdGuard VPN is sold on its own, and it has a free plan.
That single difference changes who each one is really for.
Here is how they compare on servers, speed and price.

By the end you will know which virtual private network fits your setup.
Bitdefender VPN とは何ですか?
Bitdefender VPN is the virtual private network built into Bitdefender’s products.
It hides your IP address and encrypts internet traffic on any network.
The VPN server network covers over 4,000 servers in 54 countries.
Under the hood it runs Hotspot Shield’s Catapult Hydra protocol.
You manage every licence from one Bitdefender Central account.
Public Wi-Fi protection can automatically connect you on untrusted networks.
ビットディフェンダーVPN
A fast, simple VPN attached to a full antivirus suite. Best if you already pay for a Bitdefender product.
Bitdefender VPNの価格設定
Bitdefender sells the VPN inside its yearly security bundles.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| Bitdefender Total Security | 年間59.99ドル | Households wanting antivirus plus a capped VPN |
| Bitdefender Premium Security | 年間79.99ドル | Unlimited Bitdefender Premium VPN traffic |
| Bitdefender Ultimate Security | 年間89.99ドル | Adding identity monitoring to the same bundle |
| Bitdefender Ultimate Security Plus | 年間119.99ドル | Full identity cover with advanced features |
Pricing verified September 2026.
⚠️ Pricing conflict: Bitdefender also lists a standalone Bitdefender Premium VPN at $6.99 per month, with an annual subscription of $39.99 that works out to $3.33 per month for the first year. Our source sheet records only the suite prices above, so those are the figures used across this comparison.
無料トライアル: There is no standalone free plan. A limited free version comes with an active Bitdefender security package, capped at 200MB of daily traffic.
返金保証: A 30-day money-back guarantee covers both the monthly and annual plans.
📌 注記： Payment methods include credit and debit cards plus PayPal. There is no cryptocurrency option and no bank transfer at checkout.
⚠️ 警告： The 200MB daily cap only applies while a paid Bitdefender product stays active. Let the suite lapse and the VPN connection stops with it.
Bitdefender VPNの主な利点
Here is what makes this VPN provider worth a look:
- Large server list: Over 4,000 servers across 54 countries. Picking a close server location keeps ping times low.
- Catapult Hydra speed: The Catapult Hydra protocol is tuned for fast, stable connections. WireGuard and オープンVPN are also supported.
- AES-256 encryption: Bitdefender VPN uses AES-256 encryption, the strongest option in common use. An automatic kill switch cuts all internet traffic if a server drops.
- Ad blocker and anti-tracker: It filters harmful websites and cuts intrusive ads. That also trims the targeted ads that follow you around the web.
- スプリットトンネリング: Choose which apps or domains use the VPN tunnel and which bypass it. Handy when one bank site refuses foreign IP addresses.
- Romanian base: Bitdefender sits in Romania, outside the 5 Eyes alliance. That jurisdiction is friendlier for online privacy than most.
- Real support team: Live chat runs 24/7, and phone support covers several countries. P2P file sharing is allowed on every server.
- One suite, one bill: Bitdefender has been providing VPN services inside its security packages for years. The additional features around online security are a genuine part of the value.

AdGuard VPNとは何ですか？
AdGuard VPN is a standalone VPN service from AdGuard Software Limited.
It hides your real location by routing traffic through a remote VPN server.
It also encrypts your traffic so nobody on the line can read it.
The company is the same one behind the AdGuard ad blocker and AdGuard DNS.
Everything sits under one AdGuard account, including AdGuard Temp Mail and AdGuard アシスタント.
Coverage runs to 65+ server locations across 53 countries.
🏆 Winner: AdGuard VPN
A cheap, standalone VPN with a free version you can test first. Covers Linux, Android TV and browser extensions.
AdGuard VPNの価格
An AdGuard VPN subscription comes in three lengths. Longer terms cut the monthly rate hard.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 1ヶ月 | 月額11.99ドル | Short trips and one-off testing |
| 1年 | 月額3.99ドル | Most people who want to buy AdGuard VPN |
| 2年 | 月額2.40ドル | The cheapest way to use AdGuard VPN long term |
Pricing verified September 2026.
無料トライアル: No trial is needed. The free version gives 3 GB of data every month, with speeds capped around 20 Mbps and a few server locations.
返金保証: A 30-day money back guarantee covers the yearly and two-year terms, so a long plan is close to risk free.
📌 注記： AdGuard accepts credit cards, PayPal and cryptocurrencies. Paid plans allow 10 simultaneous connections across your mobile デバイス そしてコンピューター。
⚠️ Pricing conflict: AdGuard’s own site has listed the two-year term at $119 every two years, which averages $2.99 per month, and the yearly term at $47.88. Our source sheet records $2.40 and $3.99 per month, so those are the figures used here.
AdGuard VPNの主なメリット
Here is what AdGuard offers that the bundled rivals often skip:
- A real free plan: 3 GB every month with no card needed. You can test whether the apps suit you before you spend.
- 幅広いデバイスのサポート: Windows, macOS, Android, iOS, Android TV and Linux, plus browser extensions for Chrome, Firefox and Edge.
- AES-256 and a kill switch: AdGuard VPN uses AES-256 encryption. The kill switch blocks leaks the moment a connection drops.
- DNS-level ad control: Its DNS servers can block ads and trackers. Point a device at that DNS server and AdGuard VPN blocks ads system-wide.
- Cyprus jurisdiction: AdGuard sits outside the 5/9/14 Eyes alliances and complies with GDPR. It does not record or share user data with third parties.
- Censorship-friendly protocol: The AdGuard VPN protocol masks VPN traffic as ordinary HTTPS. That helps on networks that block obvious VPN connections.
- スプリットトンネリング: Pick which apps or certain websites go through the VPN tunnel and which skip it.

機能比較
These two VPN services sit at opposite ends of the market.
Here are the ten areas that decide which one you should buy.
| 特徴 | ビットディフェンダーVPN | アドガードVPN |
|---|---|---|
| 開始価格 | $59.99/yr suite | 月額2.40ドル |
| 無料プラン | ❌ (200MB/day with suite) | ✅ 月間3GB |

| 最適な用途 | Bitdefender suite owners | Cheap standalone privacy |
1. サーバーネットワークとサーバー設置場所
ビットディフェンダーVPN: The server list runs past 4,000 machines in 54 countries. A UK server for BBC iPlayer or a US server for shopping prices is easy to reach.
アドガードVPN: Roughly 800 servers cover 65+ server locations in 53 countries. The free version narrows that to a few server locations in London, Amsterdam and Paris. Paid users get the full map.
2. Speed and Download Speeds
ビットディフェンダーVPN: Catapult Hydra is built for speed, and nearby hops hold up well. Performance falls off on distant servers, especially Japan and オーストラリア. It is not the fastest VPN available, and sits below NordVPN and エクスプレスVPN in most speed tests.
アドガードVPN: AdGuard VPN’s performance is fine for browsing but weak on data intensive tasks. Connection speeds hold up for mail and chat. Some users report drops to around 10 Mbps from a 65 Mbps baseline. Paid tests have averaged about 58.73 Mbps download, with roughly 20% loss on nearby servers.
⚠️ 警告： The AdGuard free version caps speeds near 20 Mbps. Upload speed and connection times both suffer there, which hurts video calls and online gaming.
3. Security Measures and Encryption
ビットディフェンダーVPN: AES-256 encryption, an automatic kill switch and support for WireGuard, OpenVPN and Hydra. Because the parent company sells antivirus, the same account also covers online threats outside the VPN tunnel.
アドガードVPN: The same AES-256 standard and a kill switch, but only one transport option. Its proprietary protocol has never been independently audited, which is the weak spot in its security measures.
4. Privacy Policy and Traffic Logs
ビットディフェンダーVPN: No traffic logs and no browsing history, per the policy. But there is no separate logging policy for the VPN, and the wording is vague. Some technical data is kept for fraud prevention, tied to a hashed user record and device IDs built from randomly generated tokens.
アドガードVPN: The policy states it does not log IP addresses, browsing history or connection timestamps. Cyprus keeps it outside the Eyes alliances. It collects minimal data as a data processor and processes data only to fix technical faults.
⚠️ 警告： Some reviewers have reported inconsistent leak protection on Bitdefender and raised concerns about its reliance on third-party infrastructure. Its VPN runs on Hotspot Shield’s network, so user and device IDs pass through a partner.
5. Ad Blocker and DNS Servers
ビットディフェンダーVPN: The app bundles an ad blocker and anti-tracker that filter harmful websites. It works inside the app only, so there is no system-wide DNS server to point other hardware at.
アドガードVPN: This is home turf. AdGuard puts ad filtering at the centre of all its adguard products, and you can choose DNS servers that block ads and trackers. Running the VPN in integrated mode alongside the AdGuard ad blocker gives the cleanest result. Can AdGuard VPN block ads without a second app? Yes, because blocking ads happens at the DNS layer.
Aggressive filtering can stop a site properly loading, so keep a whitelist handy.
6. Streaming Platforms and Geo Restricted Content
ビットディフェンダーVPN: This is the weakest area. It unblocks BBC iPlayer but stumbles on US Netflix, Amazon Prime Video and Disney+. There are no dedicated streaming servers, and it will not run on Apple TV or a Fire TV Stick.
アドガードVPN: It handles Netflix, Disney+ and BBC iPlayer, though Amazon Prime and Peacock resist. Buffering and longer load times show up on some platforms, so access to geo restricted content is good rather than flawless. Does AdGuard VPN work on every library? No.
7. デバイスのサポートと同時接続
ビットディフェンダーVPN: App compatibility stops at Windows, macOS, Android and iOS. No Linux, no router support, nothing for TV boxes. You still get 10 simultaneous connections per licence, the same number AdGuard allows.
アドガードVPN: Coverage stretches to Windows, macOS, Android, iOS, Android TV and Linux, plus Chrome, Firefox and Edge browser extensions. AdGuard VPN’s apps share one layout across desktop apps and mobile apps, so the AdGuard VPN app feels the same on every screen.
8. Split Tunneling and Kill Switch
ビットディフェンダーVPN: Split tunneling lets you pick which apps or domains use the tunnel. The kill switch shuts down all internet traffic if the link to a server fails, and desktop notifications tell you when that happens.
アドガードVPN: Same two features, exclusion lists included. A favorites system for saved locations means you can connect to a regular spot in a few seconds. Some users have reported occasional connection drops mid-session.
9. カスタマーサポート
ビットディフェンダーVPN: Live chat runs 24/7, phone support covers multiple countries, and email replies take at least half an hour. The catch is that the general support team handles every Bitdefender product, so you are not always talking to VPN specialists.
アドガードVPN: There is no 24/7 line. Help runs through a ticketing system and email, which is slower than most premium VPNs offer. The knowledge base is decent, but a live human is not on call.
10. 価格設定とコスト
Price is where the gap gets wide.
| プラン | ビットディフェンダーVPN | アドガードVPN |
|---|---|---|
| 無料 | ❌ No standalone free plan | ✅ 3 GB per month |
| 毎月 | ❌ Suite billing only | 月額11.99ドル |
| Entry yearly | 年間59.99ドル（トータルセキュリティ） | 月額3.99ドル（1年間契約） |
| Mid yearly | 年間79.99ドル（プレミアムセキュリティ） | 月額2.40ドル（2年間） |
| 最高級 | 年間119.99ドル（アルティメットセキュリティプラス） | ❌ No higher tier |
ビットディフェンダーVPN: You are paying for antivirus, ransomware cover and identity tools as well as a VPN. Judged as a security package, $59.99 a year is fair. Judged as a VPN alone, it is expensive.
アドガードVPN: At $2.40 a month on the two-year term, this undercuts almost every name-brand rival, including プライベートインターネットアクセス. The monthly rate of $11.99 is steep, so only pick it for short trips.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| 予算が限られている | アドガードVPN | $2.40/month on two years |
| Antivirus in the same bill | ビットディフェンダーVPN | Suite covers online threats too |
| Linux or Android TV | アドガードVPN | Bitdefender skips both |
| ほとんどのサーバー設置場所 | ビットディフェンダーVPN | 54か国に4,000台以上のサーバー |
| Help at 2am | ビットディフェンダーVPN | 24/7 chat and phone support |
| Test before paying | アドガードVPN | 3 GB free version, no card |
💰 あなたの予算
If the VPN is the only thing you want, AdGuard is far cheaper. If you were going to buy antivirus anyway, the Bitdefender bundle stops being expensive.
🔌 あなたの技術スタック
ウィンドウズ、 マック, Android and iOS users can pick either one. Linux boxes, routers and TV sticks push you straight to AdGuard.
📺 あなたのストリーミング習慣
Neither is a streaming specialist. AdGuard opens more libraries, but heavy viewers should look elsewhere.
🎓 あなたの経験レベル
Both apps are easy to use apps with one big connect button. Beginners will not feel lost in either, and neither hides all the features behind menus.
🆓 無料トライアルとデモ
Start with the AdGuard free plan to see how it performs on your line. For Bitdefender, buy a suite and lean on the refund window.
🛟 サポートオプション
Bitdefender wins here without much argument. Round-the-clock chat beats a ticket queue when a connection breaks before a deadline.

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 single users and small households. We did not measure long-run throughput on 仕事 lines, run leak audits ourselves, or check either app behind China’s firewall. Business buyers and heavy torrenters should treat our notes on online activities as a starting point, not a final answer.

🏆 WINNER: ADGUARD VPN
AdGuard VPN wins 4 out of 7 categories.
最適な用途: budget buyers, Linux and Android TV households, and anyone who wants to try before paying.
Bitdefender VPN is a feature. AdGuard VPN is a service.
Bitdefender is the better engine. More servers, faster hops, real people on the phone at 3am.
AdGuard is the better deal. It costs a fraction of the price, runs on more hardware, and its free version lets you check performance before money changes hands.
For most people buying a VPN and nothing else, AdGuard VPN is the one to start with.
The best VPN here is the one that matches your bill, not the one with the biggest server count.
