⚡ 簡単な評価:
- 価格: ビットディフェンダー 安全 suites start at $59.99/yr. OysterVPN starts at $5.99/month.
- 最適な用途: ビットディフェンダー VPN suits people who already want antivirus. OysterVPN suits people who only want a VPN.
- 主な違い： Bitdefender VPN allows 10 simultaneous connections. OysterVPN allows five.
- 私たちのおすすめ： Bitdefender VPN, because the bigger server network and 24/7 chat support cover more situations.
One of these tools comes bundled with antivirus.
The other is a standalone virtual private network with a lifetime option.
That single fact decides most of this matchup.
Bitdefender VPN rides on a huge security brand and a 4,000-server network.
OysterVPN is a small Irish vpn provider with cheap entry pricing.
Here is how the two compare on price, speed, privacy, and support.

Bitdefender VPN とは何ですか?
Bitdefender VPN is the virtual private network built into Bitdefender’s products.
It encrypts your internet traffic and hides your ip addresses behind a vpn server.
The service runs on Hotspot Shield’s Catapult Hydra protocol.
ホットスポットシールド acts as the data processor and processes data on Bitdefender’s behalf.
You get over 4,000 servers across 54 countries and 10 simultaneous connections.
Every plan is managed from your Bitdefender Central account.
🏆 Winner: Bitdefender VPN
A premium vpn folded into a full antivirus stack. Ten デバイス, 54 server locations, and 24/7 chat support.
Bitdefender VPNの価格設定
Bitdefender sells the vpn inside its 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 basic vpn access |
| 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 stack |
| Bitdefender Ultimate Security Plus | 年間119.99ドル | Families wanting every Bitdefender product in one licence |
Pricing verified September 2026.
無料トライアル: No open free trial. A capped free version ships with an active Bitdefender security package, limited to 200MB of daily traffic.
返金保証: A 30-day money back guarantee covers both monthly and annual plans.
📌 注記： Payment goes through credit or debit cards and PayPal. There is no cryptocurrency option and no bank transfer. Not every tier gives you the same number of extra tools, so check what each bitdefender product includes before you buy.
⚠️ Pricing conflict: Our CSV lists the suite prices above. Bitdefender also sells Premium VPN on its own, quoted at $6.99 per month or $39.99 for the first year, which works out near $3.33 per month. We keep the CSV figures in every table and flag the standalone price here.
Bitdefender VPNの主な利点
Here is what makes this vpn service worth a look:
- Big server list: Over 4,000 servers in 54 countries. That is wide coverage for a bundled tool.
- Ten devices: One licence protects 10 devices at once. Most rivals stop at five.
- Ad blocker and anti-tracker: It filters harmful sites and blocks intrusive ads. It also cuts targeted ads while you browse.
- キルスイッチ: An automatic kill switch cuts all internet traffic if the vpn connection drops.
- Public Wi-Fi protection: The app can automatically connect on café and airport networks. You can also set desktop notifications for each session.
- Romanian base: Bitdefender sits outside the 5 Eyes alliance. Its privacy stance benefits from that physical location.

私たちの 作家 installed the latest version on Windows and ran it for several days. Here is what stood out during that hands-on time:
Bitdefender VPNのメリットとデメリット
✅ メリット
- Over 4,000 servers in 54 countries
- 10 simultaneous connections per licence
- 24/7 live chat plus phone support
- Ad blocker, anti-tracker and split tunneling included
❌ デメリット
- No Linux, router, Apple TV or Fire TV Stick support
- Vague privacy policy with no separate vpn logging policy
- Fails on US Netflix, Prime Video and Disney+
Oyster VPNとは何ですか?
OysterVPN is a standalone vpn service based in Dublin, Ireland.
Ireland sits outside the 5, 9 and 14 Eyes alliances.
The service encrypts traffic, hides your ip address, and routes your connection through remote servers.
OysterVPN’s servers number roughly 400+ across more than 35 countries.
Each plan covers five simultaneous connections on multiple devices.
You can install OysterVPN on Windows, macOS, アンドロイド そしてiOS。
🥈 Runner Up: Oyster VPN
A small Irish vpn provider with cheap entry pricing. WireGuard, OpenVPN and IKEv2 on tap, plus a one-off lifetime plan.
Oyster VPNの料金
One tier, three billing lengths. Here is what you pay.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 1ヶ月＋2ヶ月無料 | 月額5.99ドル | Short trips and short-term testing |
| 1年 | 月額29.99ドル | Regular users who want the standard term |
| 生涯アクセス | 月額59.99ドル | One-off buyers who want lifetime access |
Pricing verified September 2026.
無料トライアル: None. There is no free tier either, so the refund window is your only way to test the service risk free.
返金保証: Every OysterVPN subscription carries a 30-day money back guarantee.
📌 注記： You can purchase OysterVPN with major credit cards or PayPal only. Cryptocurrency is not accepted, and neither is bank transfer.
⚠️ Pricing conflict: The CSV row above labels the 1-Year and Lifetime figures “per month”, which reads as a data entry slip. Vendor material quotes $9.99 monthly with three months free, roughly $2.50 per month yearly, and $49.99 once for lifetime access. We keep the CSV numbers in our tables and flag the gap here.
Oyster VPNの主な利点
These are the OysterVPN features that earn their keep:
- Protocol choice: You pick from secure vpn protocols including WireGuard, OpenVPN and IKEv2. Bitdefender gives you no such menu.
- Leak blocking: IP leak protection and DNS leak protection stop accidental data leaks. WebRTC requests are covered too.
- Internet kill switch: Traffic halts the moment the tunnel fails. It is a crucial feature on flaky ホテル Wi-Fi。
- Torrent friendly: P2P is allowed on every server, with DDoS protection layered on top.
- Ad and malware blocker: A built-in filter strips ads and known bad domains before they load.
- 生涯オプション： One payment buys lifetime access. Very few vpn providers still offer that.

機能比較
Ten rounds, side by side. The summary table first, then the detail.
| 特徴 | ビットディフェンダーVPN | オイスターVPN |
|---|---|---|
| 開始価格 | 年間59.99ドル | 月額5.99ドル |
| 無料プラン | ✅ 200MB/day with a suite | ❌ |
| サーバー | ✅ 4,000+ in 54 countries | ✅ 400+ in 35+ countries |

| ライブチャット | ✅ 24時間365日 | ❌ メールのみ |
| Linuxサポート | ❌ | ❌ |
| 最適な用途 | Antivirus users adding a tunnel | Budget buyers wanting a vpn only |
1. Encryption and Security Features
ビットディフェンダーVPN: AES-256 encryption protects every session, and the tunnel runs on Catapult Hydra. Bitdefender also lists WireGuard and OpenVPN support in its documentation, though Windows leans on Hydra. You get no protocol dropdown, so the app picks for you.
オイスターVPN: Same AES-256 standard, but you choose the vpn protocols yourself. WireGuard, OpenVPN and IKEv2 all sit in the settings menu. That control matters when a network blocks one protocol and you need another.
⚠️ 警告： Vendor material on OysterVPN is inconsistent about WireGuard. Some pages list it, others say it is missing. Check the app before you buy if that protocol is the reason you are switching.
2. No Logs Policy and Jurisdiction
ビットディフェンダーVPN: Romania is a friendly base, and the company says it keeps no traffic logs or browsing history. The catch is the paperwork. There is no separate logging policy for the vpn, and the general policy is vague about hashed user and device IDs plus randomly generated tokens held for fraud prevention.
オイスターVPN: Ireland sits outside the intelligence-sharing blocs, and the company advertises a strict no logs policy. Neither side has an audited no logs policy, so both rest on trust. A zero logging policy without a third-party check is a claim, not proof.
3. Server Network and Server Locations
ビットディフェンダーVPN: Over 4,000 servers in 54 countries gives you plenty of options for any server location. The server list is searchable and includes a favorites system for the spots you reuse. Its UK server handles BBC iPlayer reliably.
オイスターVPN: The server network is far smaller. Public counts range from 150+ servers in 17 countries to 400+ in 35+ countries, depending on the source. A limited network hurts when the nearest node is busy.
4. Speed and Download Speeds
ビットディフェンダーVPN: Catapult Hydra is built for pace, and connection times land within a few seconds on a nearby server. Download speeds hold up well in Europe and North America. Performance sags on distant servers, especially Japan and Australia, and it trails ノードVPN and ExpressVPN overall.
オイスターVPN: OysterVPN’s speeds are fine on a nearby server and weak far away. Any speed test on a long-haul route can show download speed and upload speed falling by around 55%. Ping times stay usable for browsing, but 4K streaming stutters.
5. Streaming and Geo Restricted Content
ビットディフェンダーVPN: It assists in bypassing geo-restrictions and opens BBC iPlayer without fuss. It has no dedicated streaming servers, and it fails on US Netflix, Amazon Prime Video and Disney+. Apple TV and Fire TV Stick are not supported, so streaming devices need a workaround.
オイスターVPN: OysterVPN offers dedicated streaming servers and unblocks more popular streaming services, including Netflix, Max and ESPN+. Hulu and Disney+ still resist. For geo restricted content on a laptop, it is the stronger pick of the two.
6. キルスイッチと漏洩防止
ビットディフェンダーVPN: The automatic kill switch cuts your internet connection the moment the tunnel drops. Some users have reported inconsistent leak protection, which is the main knock against its advanced security features.
オイスターVPN: The internet kill switch does the same job, and leak protection covers IP, DNS and WebRTC. DNS requests stay inside the vpn tunnel, which limits accidental data leaks on public networks.
7. Split Tunneling and Ad Blocking
ビットディフェンダーVPN: Split tunneling works on both apps and domains, so certain websites can skip the tunnel entirely. The ad blocker and anti-tracker are additional features you would normally pay extra for.
オイスターVPN: The split tunneling feature only runs on Windows and Android. Mac and iPhone users lose it. The ad and malware blocker is on every platform.
8. Devices and Simultaneous Connections
ビットディフェンダーVPN: Ten devices per licence, covering Windows, macOS, Android and iOS. The mobile apps mirror the desktop apps closely. There is no Linux client and no router support, which rules out whole-home coverage.
オイスターVPN: Five devices, same four platforms. The OysterVPN apps are intuitive apps with a user friendly interface, but native Linux is missing and there is no smart TV or console client. Neither service offers unlimited connections, and neither leans on browser extensions.
9. カスタマーサポート
ビットディフェンダーVPN: Live chat support runs 24/7, phone support covers several countries, and email replies take roughly half an hour or more. Tickets go to the general support team rather than vpn specialists. The knowledge base is deep, so following Bitdefender’s instructions solves most setup problems.
オイスターVPN: Customer support is thin. There is no phone number and no chat support, and email replies are slow by user accounts. That is the cost of buying from a small vpn provider.
10. 価格設定とコスト
Here are both price lists next to each other.
| ティア | ビットディフェンダーVPN | オイスターVPN |
|---|---|---|
| 無料 | 200MB/day with a suite | ❌ |
| エントリ | 年間59.99ドル（トータルセキュリティ） | $5.99/month (1-Month +2 Months free) |
| 中 | 年間79.99ドル（プレミアムセキュリティ） | 月額29.99ドル（1年間契約） |
| トップ | 年間119.99ドル（アルティメットセキュリティプラス） | $59.99/month (Lifetime Access) |
ビットディフェンダーVPN: You are buying a security package, not just a tunnel. Antivirus, anti-tracker and device protection ride along with the vpn connection. If you would have bought antivirus anyway, the bundle is good value.
オイスターVPN: You are buying one thing and paying less for it. The lifetime plan removes renewals entirely, which suits people tired of annual price hikes. Just remember the smaller network and thinner support come with it.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| 最低価格 | オイスターVPN | $5.99 first month |
| Antivirus in the same bill | ビットディフェンダーVPN | Bundled security package |
| Netflixのブロック解除 | オイスターVPN | 専用ストリーミングサーバー |
| ほとんどのデバイスが対象 | ビットディフェンダーVPN | 10 connections vs five |
| Protocol control | オイスターVPN | WireGuard、OpenVPN、IKEv2 |
| Help at 2am | ビットディフェンダーVPN | 24/7 live chat and phone |
💰 あなたの予算
OysterVPN wins on sticker price and offers lifetime access. Bitdefender only makes financial sense if you also want antivirus.
🔌 あなたの技術スタック
Neither one runs on Linux or a router. If your stack includes either, look at specialist providers instead.
📺 あなたのストリーミング習慣
Bitdefender handles BBC iPlayer but stalls on Netflix and Disney+. OysterVPN opens more libraries, as long as you pick the fastest server nearby.
🎓 あなたの経験レベル
Beginners get on fine with either app. Bitdefender hides the advanced features, while the OysterVPN iOS app and Windows client expose more settings.
🆓 無料トライアルとデモ
Neither runs a real trial, so lean on the refund window. Test connection speeds on nearby servers during week one.
🛟 サポートオプション
This one is not close. Round-the-clock humans beat a slow 受信トレイ every time you hit a real problem.

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 test 仕事 licensing, router flashing, or use in restrictive countries beyond published reports. Neither service works dependably in China. Speed figures come from vendor material and public testing, not a controlled lab run by us, so your own online activities and local ISP will shift the numbers.

🏆 WINNER: BITDEFENDER VPN
Bitdefender VPN takes 4 of 7 categories.
最適な用途: households with many devices, antivirus buyers, people who want real-time help
These two are not chasing the same buyer. Bitdefender sells online privacy as part of a wider security package. OysterVPN sells a tunnel and nothing else.
OysterVPN is a decent vpn for the money, and the streaming results are better. The small server network, the missing audit and the email-only help desk keep it in second place.
If you want one bill covering malware and a tunnel across 10 devices, Bitdefender is the safer buy.

よくある質問
Bitdefender VPNは信頼できるのか？
Mostly. Romanian jurisdiction and AES-256 help, and no browsing history is stored. The privacy policy is vague about technical data, and there is no independent audit.
Bitdefender VPNの月額料金はいくらですか？
The standalone Premium tier is quoted at $6.99 monthly. Our CSV pricing lists the bundles instead, starting at $59.99 per year for Total Security.
Oyster VPNは良いサービスですか？
It is fine for browsing, torrenting and most streaming. The small network, missing audit and email-only help desk keep it out of the front rank.
Oyster VPNの本社はどこにありますか？
Dublin, Ireland. That places the company outside the 5, 9 and 14 Eyes intelligence alliances, which is a reasonable spot for a privacy tool.
Bitdefender Premium VPNは無制限ですか？
Yes, the paid tier has no data cap. The free version bundled with a security suite stops at 200MB per day, which runs out fast.
