⚡ 快速结论：
- 定价： Bitdefender 安全 suites start at $59.99/yr. OysterVPN starts at $5.99/month.
- 最适合： Bitdefender VPN suits people who already want antivirus. OysterVPN suits people who only want a VPN.
- 主要区别： Bitdefender VPN allows 10 simultaneous connections. OysterVPN allows five.
- 我们的选择： 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 定价

免费试用： No open free trial. A capped free version ships with an active Bitdefender security package, limited to 200MB of daily traffic.
退款保证： A 30-day money back guarantee covers both monthly and annual plans.
📌 笔记： 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 的主要优势
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.
- 终止开关： 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.

我们的 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 的优缺点
✅ 优点
- 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
❌缺点
- 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+
什么是 Oyster VPN？
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, 安卓 以及 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 定价
One tier, three billing lengths. Here is what you pay.
| 计划 | 价格 | 最适合 |
|---|---|---|
| 1 个月 + 2 个月免费 | 每月 5.99 美元 | Short trips and short-term testing |
| 1年 | 每月 29.99 美元 | Regular users who want the standard term |
| 终身访问权限 | 每月 59.99 美元 | One-off buyers who want lifetime access |
Pricing verified September 2026.
免费试用： None. There is no free tier either, so the refund window is your only way to test the service risk free.
退款保证： Every OysterVPN subscription carries a 30-day money back guarantee.
📌 笔记： 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 的主要优势
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 酒店 无线上网。
- 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.
- 终身选项： One payment buys lifetime access. Very few vpn providers still offer that.

功能对比
Ten rounds, side by side. The summary table first, then the detail.
| 特征 | Bitdefender VPN | Oyster VPN |
|---|---|---|
| 起价 | 每年 59.99 美元 | 每月 5.99 美元 |
| 免费计划 | ✅ 200MB/day with a suite | ❌ |
| 服务器 | ✅ 4,000+ in 54 countries | ✅ 400+ in 35+ countries |
| 同时连接 | ✅ 10 | ✅ 5 |
| WireGuard / OpenVPN | ❌ Catapult Hydra only | ✅ Plus IKEv2 |
| 独立审计 | ❌ | ❌ |
| Netflix & Disney+ | ❌ | ✅ Netflix, not Disney+ |
| 在线聊天 | ✅ 全天候 24/7 | ❌ 仅限电子邮件 |
| Linux 支持 | ❌ | ❌ |
| 最适合 | Antivirus users adding a tunnel | Budget buyers wanting a vpn only |
1. Encryption and Security Features
Bitdefender 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.
Oyster 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
Bitdefender 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.
Oyster 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
Bitdefender 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.
Oyster 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
Bitdefender 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 NordVPN and ExpressVPN overall.
Oyster 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
Bitdefender 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.
Oyster 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. 紧急停止开关和泄漏保护
Bitdefender 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.
Oyster 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
Bitdefender 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.
Oyster 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
Bitdefender 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.
Oyster 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. 客户支持
Bitdefender 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.
Oyster 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. 定价与成本
Here are both price lists next to each other.
| 层级 | Bitdefender VPN | Oyster VPN |
|---|---|---|
| 自由的 | 200MB/day with a suite | ❌ |
| 入口 | 59.99美元/年（全面安保） | $5.99/month (1-Month +2 Months free) |
| 中 | 79.99美元/年（高级安全套餐） | 每月 29.99 美元（1 年） |
| 顶部 | 119.99美元/年（终极安全增强版） | $59.99/month (Lifetime Access) |
Bitdefender 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.
Oyster 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.
不同场景
| 如果您需要…… | 选择 | 为什么 |
|---|---|---|
| 最低入门价格 | Oyster VPN | $5.99 first month |
| Antivirus in the same bill | Bitdefender VPN | Bundled security package |
| Netflix 解锁 | Oyster VPN | 专用流媒体服务器 |
| 涵盖的大多数设备 | Bitdefender VPN | 10 connections vs five |
| Protocol control | Oyster VPN | WireGuard、OpenVPN、IKEv2 |
| Help at 2am | Bitdefender VPN | 24/7 live chat and phone |
💰 您的预算
OysterVPN wins on sticker price and offers lifetime access. Bitdefender only makes financial sense if you also want antivirus.
🔌 您的技术栈
Neither one runs on Linux or a router. If your stack includes either, look at specialist providers instead.
📺 你的流媒体观看习惯
Bitdefender handles BBC iPlayer but stalls on Netflix and Disney+. OysterVPN opens more libraries, as long as you pick the fastest server nearby.
🎓您的经验水平
Beginners get on fine with either app. Bitdefender hides the advanced features, while the OysterVPN iOS app and Windows client expose more settings.
🆓 免费试用和演示
Neither runs a real trial, so lean on the refund window. Test connection speeds on nearby servers during week one.
🛟 支持选项
This one is not close. Round-the-clock humans beat a slow 收件箱 every time you hit a real problem.

我们的评测没有涵盖的内容
This comparison focused on home users and small households. We did not test 商业 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.
最适合： 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.

常见问题解答
Bitdefender VPN 可信吗？
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每月费用是多少？
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好用吗？
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的总部在哪里？
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 是否无限流量？
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.
