Avast VPN là gì?
Avast SecureLine VPN is the VPN service bundled with Avast antivirus.
Nó mã hóa kết nối internet của bạn và che giấu địa chỉ IP của bạn.
The network is small: around 700 servers in 34 countries.
Avast SecureLine runs on Windows, Mac, Android, iOS and Android TV.
One subscription covers 10 devices at once.
Most people meet it through other Avast products rather than by choice.
Here is a closer look at the app before we compare it.
Avast SecureLine VPN
A 60 day free trial, 10 devices and Android TV support. Protocol choice covers OpenVPN, WireGuard and the in-house Mimic protocol.
Bảng giá Avast VPN
Avast sells the VPN inside its security plans. Here is the current line-up.
| Kế hoạch | Giá | Tốt nhất cho |
|---|---|---|
| Phần mềm diệt virus miễn phí | Miễn phí | Basic malware protection with no VPN |
| Bảo mật cao cấp | 49,99 đô la/năm đầu tiên | Device security plus the VPN app |
| Tối thượng | 49,99 đô la/năm đầu tiên | Security, VPN, cleanup and AntiTrack |
Pricing verified September 2026.
Dùng thử miễn phí: Yes. A 60 day free trial, one of the longest in the category. You must add payment information first, but nothing is charged until day 61.
Đảm bảo hoàn tiền: Avast offers a 30 day refund window on paid plans bought directly.
📌 Ghi chú: Avast has dropped the monthly subscription for the VPN. Standalone SecureLine terms are sold yearly, and the app is included in the bundles above.
⚠️ Cảnh báo: Avast’s own pages have quoted standalone SecureLine terms near $4.59/month (one year), $4.29/month (two years) and $4.39/month (three years). Our table follows the plan dữ liệu above. Check the checkout total before you buy, because first-year prices renew higher.
Những lợi ích chính của Avast VPN
Here is what you actually get:
- 60 day trial: Two months of full access beats the 7 day free trials most vpns hand out. You can test streaming and torrenting properly.
- Smart VPN mode: You set rules so the app can automatically connect on a public network or a banking site. Smart VPN also turns itself off where you don’t need it.
- Ten devices: One plan covers phones, laptops and a TV. Useful if you protect a household rather than one device.
- Protocol choice: You get the OpenVPN protocol, WireGuard and the proprietary Mimic protocol for restricted networks.
- Purpose-built servers: Avast SecureLine VPN servers include streaming optimized servers and torrenting servers, so you don’t guess which location works.
- Công tắc ngắt khẩn cấp: If the connection drops, internet traffic stops instead of leaking your real IP address.
- Everyday privacy: Masking your location limits price discrimination and adds online privacy from an ISP that profiles your browsing data.

Oyster VPN là gì?
OysterVPN is a smaller VPN provider run from Dublin, Ireland.
Ireland sits outside the 5/9/14 Eyes alliances.
The service routes your traffic through a VPN tunnel to a VPN server.
That hides your physical location and your real IP addresses.
OysterVPN’s servers number roughly 400+ across 35+ countries.
The headline is lifetime access for a single payment.
The video below walks through the OysterVPN app.
OysterVPN
AES-256 encryption, dedicated streaming servers and torrenting on every server. Every plan carries a 30 day money back guarantee, so you can test the service risk free.
Bảng giá Oyster VPN
One feature set, three terms. Pick how long you want to pay for.
| Kế hoạch | Giá | Tốt nhất cho |
|---|---|---|
| 1 tháng + 2 tháng miễn phí | 5,99 đô la/tháng | Short trips and short tests |
| 1 năm | 29,99 đô la/tháng | Steady year-round use |
| Quyền truy cập trọn đời | 59,99 đô la/tháng | Paying once instead of renewing |
Pricing verified September 2026.
Dùng thử miễn phí: None. OysterVPN has no free tier and no trial, so free trials are not part of the sân bóng đá.
Đảm bảo hoàn tiền: Every plan carries a 30 day money back guarantee.
📌 Ghi chú: To purchase OysterVPN you need a major credit card or PayPal. Cryptocurrency is not accepted.
⚠️ Cảnh báo: Public OysterVPN pages have advertised $9.99 monthly with three months free, $2.50/month on the yearly term and a $49.99 one-off for lifetime access. Our table follows the plan data above, so confirm the total at checkout. Our rating for OysterVPN also comes from our own review page, since the product row carries no stored score.
Những lợi ích chính của Oyster VPN
The OysterVPN features that matter most in this matchup:
- Quyền truy cập trọn đời: Pay once instead of renewing every year. That is the single strongest reason people buy an OysterVPN subscription.
- Máy chủ phát trực tuyến chuyên dụng: Netflix, Max and ESPN+ work on the streaming servers, and BBC iPlayer is usually reachable too.
- Torrenting everywhere: P2P runs on every server, with no separate list of torrent locations to hunt for.
- Layered leak protection: IP leak protection covers DNS requests and WebRTC, and DNS leak protection is on by default.
- Ad and malware blocking: The blocker is built in, so you skip extra browser extensions.
- DDoS protection: Useful for competitive gaming, where a flooded connection ends the match.
- Irish base: Outside the Eyes alliances, under GDPR, with a strict no logs policy on paper.

So sánh tính năng
Here are the ten areas that decide this matchup. The table gives you the shape of it, then we dig into each one.
| Tính năng | Avast SecureLine VPN | OysterVPN |
|---|---|---|
| Giá khởi điểm | $49.99/first yr (bundled) | 5,99 đô la/tháng |
| Free Plan or Trial | Loading... | ❌ Không có |
| Mạng máy chủ | ~700 servers, 34 countries | 400+ servers, 35+ countries |
| Các thiết bị đồng thời | 10 | 5 |
| Name | ✅ | ✅ |
| Chia đường hầm | ✅ | ✅ Windows and Android only |
| Máy chủ phát trực tuyến chuyên dụng | ✅ | ✅ |
| Tải torrent trên tất cả các máy chủ | ❌ Specific servers | ✅ |
| Android TV App | ✅ | ❌ |
| Kiểm toán độc lập | ❌ | ❌ |
| Tốt nhất cho | Households already on Avast | One-time payment buyers |
1. Mạng máy chủ và vị trí máy chủ
Avast SecureLine VPN: Around 700 servers spread over 34 countries. That is small next to the big vpn providers, and coverage thins out in the Middle East, Africa and South America. If your work depends on one obscure server location, check the list before paying.
OysterVPN: Roughly 400+ servers in 35+ countries, so it edges Avast on breadth of server locations while trailing on raw count. Published figures vary between OysterVPN’s own pages, which is worth knowing before you commit.
2. Connection Speeds and VPN Protocols
Avast SecureLine VPN: Reported speed tests show a fast connection on nearby servers and a steep fall on distant servers. You get the OpenVPN protocol, WireGuard and Mimic, which is built to get a vpn connection through networks that block the usual traffic.
OysterVPN: The same pattern, only sharper. A typical speed test shows decent numbers on a nearby server, then OysterVPN’s speeds drop by around 55% at long range. Download speed holds up for browsing; upload speed and 4K streaming suffer. Secure vpn protocols include OpenVPN and IKEv2, with WireGuard missing from some apps.
⚠️ Cảnh báo: Neither is a fast vpn over intercontinental hops. Pick the fastest server near you and expect a slower internet connection on anything far away.
3. Các tính năng bảo mật và mã hóa
Avast SecureLine VPN: The security features are the standard set: AES-256 encryption, a kill switch and DNS leak protection. Smart VPN mode adds a layer most rivals skip, letting the app connect itself on public Wi-Fi and stand down on your home wi fi network.
OysterVPN: AES-256 encryption, an internet kill switch, IP leak protection and DDoS protection. The advanced security features lean toward gamers and torrenters rather than people worried about surveillance.
4. Privacy, Logs Policy and Independent Audits
Avast SecureLine VPN: This is the weak spot. Avast records timestamps, data volumes and connection details, though it says nothing identifiable is kept. There is no independent audit, and the FTC fined Avast $16.5 million in February 2024 over the Jumpshot subsidiary that sold browsing data. The Czech Republic base is outside the major alliances, which helps a little.
OysterVPN: A strict no logs policy on paper, backed by Irish jurisdiction and GDPR. But the zero logging policy has never been through independent audits either, so both companies are asking for the same trust. Neither has an audited no logs policy the way NordVPN làm.
5. Streaming Servers and Unblocking
Avast SecureLine VPN: Streaming optimized servers handle popular streaming services like Netflix, Disney+ and Amazon Prime Video, with mixed results elsewhere. Hulu and BBC iPlayer are the usual sticking points, and the Android TV app means you can use Avast SecureLine VPN on streaming devices directly.
OysterVPN: Dedicated streaming servers unblock several streaming services, including Netflix, Max, ESPN+ and BBC iPlayer. Hulu and Disney+ are the weak spots. There is no smart TV app, so geo restricted content has to come through a laptop, phone or router.
6. Tải torrent và P2P
Avast SecureLine VPN: P2P is allowed, but only on specific torrenting servers. You have to pick the right location, and those servers are tuned to avoid throttling during heavy transfers.
OysterVPN: Torrenting runs on every server, with P2P-ready locations for the best download speed. For heavy downloaders this is the clearest practical win in the whole comparison.
7. Apps and Multiple Platforms
Avast SecureLine VPN: The Windows app, Mac, iOS and Android app all look the same, and Android TV is covered. Ten devices on one plan is generous, and the layout is easy for beginners who just want to connect and forget.
OysterVPN: The OysterVPN apps cover Windows and Mac desktop apps, an iOS app, an Android app and browser extensions. There is no native Linux client and no console support. Five simultaneous connections cover multiple devices but not a full household, and neither service offers unlimited connections.
8. Split Tunneling, Kill Switch and Leak Protection
Avast SecureLine VPN: Split tunneling, a kill switch for connection drops and protection against DNS leaks. Smart rules can route banking sites outside the tunnel while the browser stays covered.
OysterVPN: The split tunneling feature only works on Windows and Android, which is a real gap on Mac and iOS. Leak protection covers IP, DNS and WebRTC leak protection, and the kill switch cuts traffic the moment a vpn connection drops. That is the crucial feature for anyone downloading files, since it stops accidental data leaks.
9. Hỗ trợ khách hàng
Avast SecureLine VPN: A large help centre plus ticket support. Reviews of Avast’s customer support are mixed, with slow or scripted replies a common complaint.
OysterVPN: Support is thinner. There is no phone line, chat support is limited, and email replies are reported as slow. That matters if an outage lands mid-deadline.
10. Định giá & Chi phí
Side by side, the plans look nothing alike.
| Kế hoạch | Avast SecureLine VPN | OysterVPN |
|---|---|---|
| Gói miễn phí | Free Antivirus: Free | ❌ |
| Gói trả phí khi đăng ký | Gói bảo mật cao cấp: 49,99 đô la/năm đầu tiên | 1-Month +2 Months free: $5.99/month |
| Kế hoạch giữa chừng | Gói cao cấp: 49,99 đô la/năm đầu tiên | 1-Year: $29.99/month |
| Long-term option | Yearly terms only | Lifetime Access: $59.99/month |
| Risk-free window | Dùng thử miễn phí 60 ngày | Đảm bảo hoàn tiền trong 30 ngày |
Avast SecureLine VPN: You are buying a security bundle, not just a vpn app. If you already want antivirus, cleanup and AntiTrack, the VPN rides along at no extra cost. If you only want a tunnel, you are paying for parts you will never open.
OysterVPN: OysterVPN offers a single feature set at three price points, so there is no upsell ladder to climb. The lifetime option is the draw, but it also means trusting a small vpn service to still exist in five years.
Các kịch bản khác nhau
| Nếu bạn cần… | Chọn | Tại sao |
|---|---|---|
| To test before paying | Avast SecureLine VPN | 60 day trial, no charge upfront |
| One payment, no renewals | OysterVPN | Lifetime plan exists |
| Tải torrent dung lượng lớn | OysterVPN | P2P trên mọi máy chủ |
| Cover a whole household | Avast SecureLine VPN | 10 devices, Android TV included |
| Split tunneling on Mac | Avast SecureLine VPN | Oyster limits it to Windows and Android |
| Verified privacy claims | Không | No independent audits on either side |
💰 Ngân sách của bạn
OysterVPN wins on entry price and on the pay-once route. Avast only makes financial sense if you want the antivirus and cleanup tools in the same purchase.
🔌 Bộ công nghệ của bạn
Linux users and console gamers should stop at OysterVPN’s app list, because neither is covered. Avast supports more multiple platforms, including the living room.
📝 Các hoạt động trực tuyến của bạn
Torrenters get more from OysterVPN. People who mainly want a private browser session on café internet get more from Avast’s rules-based setup.
🎓 Trình độ kinh nghiệm của bạn
Both are beginner-friendly, with a user friendly interface and intuitive apps that need one tap to connect. Avast’s smart rules are the only part that rewards fiddling.
🆓 Dùng thử và bản demo miễn phí
Avast lets you run the full app for two months before paying, though it takes card details upfront. OysterVPN has no trial, so the refund window is your only test drive.
🛟 Các tùy chọn hỗ trợ
Avast has the bigger help centre and ticket system. OysterVPN’s customer support is email-first and slower, which matters if a VPN outage blocks your work.

Những điều mà bài đánh giá của chúng tôi chưa đề cập
We focused on everyday home use: browsing, streaming, torrenting and public network safety. We did not run lab-grade stress tests, measure every server location, or check either service inside China. Việc kinh doanh licensing and router setups also sit outside this comparison. If you need a VPN for censorship-heavy du lịch, treat these findings as a starting point rather than an answer.

🏆 WINNER: AVAST SECURELINE VPN
Avast SecureLine VPN takes 4 of 8 categories, with OysterVPN on 3 and one tie.
Phù hợp nhất cho: households with many devices, Android TV streaming, and anyone who wants to try a VPN properly before paying.
Avast SecureLine VPN wins on breadth. Ten devices, more platforms and a two-month trial give you room to decide without risk.
OysterVPN wins on cost and on torrenting. If you download a lot and hate renewals, that combination is hard to argue with.
Privacy is the uncomfortable part. Avast carries a real regulatory penalty on its record, and OysterVPN carries no verification at all. Paying more does not always buy more security.
Avast is a good vpn for a busy household on a budget. Many vpns run bigger networks, and both vpn services trail the leaders on online security proof, so if audited privacy is your priority, look at the best vpns with published audits instead.

Câu hỏi thường gặp
Avast VPN có thực sự hiệu quả không?
Yes. It encrypts traffic, hides your IP address and unblocks Netflix, Disney+ and Prime Video. Speeds hold up on nearby servers and fall away on long-distance connections.
Avast SecureLine VPN có an toàn để sử dụng không?
The encryption and kill switch are sound. The trust problem is bigger: no independent audit, plus a $16.5 million FTC penalty in 2024 over data sold by a subsidiary.
Avast VPN có giá bao nhiêu mỗi tháng?
There is no monthly option now. The app ships inside Premium Security or Ultimate, both $49.99 for the first year, with standalone terms sold by the year.
Oyster VPN có tốt không?
It is a decent vpn for budget users. Nearby speeds, torrenting and streaming all hold up. Distant servers, five connections and unverified privacy claims are the trade-offs.
Trụ sở chính của Oyster VPN nằm ở đâu?
Dublin, Ireland. The country sits outside the 5/9/14 Eyes alliances and falls under GDPR, which gives the service a friendlier legal home than a US or UK base.
