Avast VPN là gì?
Avast SecureLine VPN is a consumer virtual private network from the Avast security company.
It encrypts your internet connection and swaps your real ip address for a shared one.
The network is small: roughly 700 servers across 34 countries.
Many VPNs run ten times that count, so your location choice is limited.
The vpn app supports OpenVPN, WireGuard, and Avast’s own Mimic protocol.
You install it on Windows, Máy MacAndroid, iOS và Android TV.
Here is the service walked through end to end, if you prefer watching to reading.
🏆 Winner: Avast VPN
A simple vpn service for everyday online privacy. One subscription covers up to 10 devices. The 60 day free trial needs payment information but no upfront charge.

Dùng thử miễn phí: 60 day free trial on every supported platform. You must enter payment information, but nothing is charged during the 60 day trial.
Đảm bảo hoàn tiền: Avast products carry a 30-day refund window on annual purchases.
📌 Ghi chú: There is no monthly billing option. The shortest term is one year, and that first-year price jumps at renewal.
⚠️ Cảnh báo: The trial auto-converts to a paid subscription. Cancel before day 60 if you do not want to be billed.
Những lợi ích chính của Avast VPN
Here is what Avast SecureLine does well:
- 60 day free trial: One of the longest free trials in the category. Most rivals give you 7 days.
- Smart VPN mode: You set rules so the app can automatically connect on banking sites or an untrusted public network.
- Công tắc ngắt khẩn cấp: Cuts your internet if the vpn tunnel fails. Nothing leaks when the connection drops.
- Public wi fi protection: Encryption blocks man-in-the-middle attacks on open wi fi at cafes and airports.
- Ten devices, one subscription: Cover a laptop, a phone, and a TV rather than one device at a time.
- Easy install: Download, sign in, hit connect. The windows app and android app are beginner-friendly.
- Tracker resistance: Hiding your ip address limits how advertisers and your ISP profile your browsing data and online activities.

The same session is recorded below, including the apps and the connect flow.
Ưu điểm và nhược điểm của Avast VPN
✅ Ưu điểm
- 60 day free trial is longer than most competitors offer
- Connects up to 10 devices on a single subscription
- Smart VPN mode can turn protection on by itself
- Clean app that beginners can use without a manual
- Based in the Czech Republic, outside major data-sharing alliances
❌ Nhược điểm
- Loading...
- The FTC fined Avast $16.5 million in February 2024 over consumer privacy

Tailscale là gì?
Tailscale là một mạng VPN dạng lưới không tin cậy (zero-trust mesh VPN) được xây dựng trên giao thức WireGuard.
It links your own devices into one private network called a tailnet.
Each computer gets a stable 100.x.y.z address, so remote access just works.
Your network traffic goes device to device, not through a company data centre.
That decentralised design eliminates single points of failure in the connection path.
The tailscale client runs on Windows, Mac, Linux, iOS, Android, and Apple TV.
The walkthrough below shows the install and the first connection in real time.
Cân đuôi
Secure networking for your own machines. The free tier covers up to 100 devices. Sign in with an existing identity provider account and you are running in minutes.
Định giá quy mô nhỏ
Tailscale charges per user, not per gigabyte.
| Kế hoạch | Giá | Tốt nhất cho |
|---|---|---|
| Riêng tư | Miễn phí mãi mãi! | Free users and home labs, up to 100 devices |
| Cộng thêm cá nhân | 5 đô la/tháng | Individual users who want more seats and features |
Pricing verified September 2026.
⚠️ Lưu ý về giá cả: Tailscale also lists việc kinh doanh tiers near $6 and $18 per user. Those sit outside our verified table above, so confirm team pricing on the vendor’s page before you commit.
Dùng thử miễn phí: The Personal plan is free forever, so free trials are not really the point. Sign up with a custom domain and you get a 14-day Enterprise trial instead.
Đảm bảo hoàn tiền: No published refund window. Start free, then upgrade only if you need to.
📌 Ghi chú: The free plan keeps some access-control features that paid tiers price differently. Read the plan page before you assume upgrading adds everything.
⚠️ Cảnh báo: Free-tier support is email only and limited to việc kinh doanh hours. There is no phone line and no 24/7 desk.
Lợi ích chính của việc thu gom rác thải quy mô lớn
Here is where Tailscale earns its reputation:
- Direct encrypted tunnels: WireGuard links each device to the next with no central hop. Latency stays low because traffic skips the middleman.
- MagicDNS: Reach a machine by name instead of memorising an address. Your office NAS becomes a hostname.
- Identity-based access: Permissions follow people, not IPs. Over 100 identity providers plug in for single sign-on.
- Exit node option: Route your internet through a device you own and Tailscale behaves like a normal VPN.
- Subnet routers: A printer or camera that cannot run the client still joins through a subnet router.
- Works across infrastructure: Home hardware, Google Cloud, and on-premise resources share one flat network.
- Incremental rollout: Add devices one at a time. No rip-and-replace of your existing setup.

- Free plan connects up to 100 devices
- Traffic never routes through Tailscale’s own servers
- Setup takes minutes with no manual configuration
- Access control policies handle custom roles and groups
- Single sign-on with more than 20 identity providers
❌ Nhược điểm
- Does not hide your ip address unless you configure an exit node
- No streaming servers, so Netflix and BBC iPlayer stay blocked
- Support is email only and not available around the clock
- Concepts like ACLs and subnet routers take reading to grasp

1. Core Purpose and Network Design
Avast VPN: Traffic leaves your machine, travels through a vpn tunnel, and exits from one of the Avast SecureLine VPN servers. Websites see that server, not you. This is the classic model behind most vpns sold to consumers.
Vảy đuôi: There is no middle server by default. Each device talks straight to other devices over an encrypted link, using UDP hole punching to get through home routers. Tailscale works as a private overlay, not as an anonymity layer.
2. Security Features and Encryption
Avast VPN: You get the OpenVPN protocol, WireGuard, and the in-house Mimic protocol for restrictive networks. A kill switch stops traffic if the link fails. DNS leak protection and WebRTC leak protection are handled inside the app rather than through browser extensions.
Vảy đuôi: Everything rides on WireGuard end to end. The control plane only brokers keys, so the company never sees your payload. There is no kill switch, because there is no shared exit to leak from.
⚠️ Cảnh báo: Neither product has published an independent audit of its privacy claims. If verified no-logs matters to you, look at audited providers instead.
3. Privacy Record and Trust
Avast VPN: This is the weak spot. Avast ran a subsidiary called Jumpshot that sold user data gathered by its antivirus, and in February 2024 the FTC ordered a $16.5 million payment over consumer privacy. The logging policy records timestamps and data volumes but no identifying detail, and no independent audit backs that up.
Vảy đuôi: No comparable scandal on the record. Because your data never crosses their infrastructure, there is far less to log in the first place. Independent audits are still absent, so trust rests on the architecture rather than on paperwork.
4. Tốc độ và hiệu năng
Avast VPN: Speed tests point the same way every time. Nearby servers hold a fast connection, distant ones fall off hard. With 34 countries on the list, users in the Middle East or South Asia often have no close option, which is why it is not the fast vpn some reviews claim.
Vảy đuôi: Direct paths beat hub-and-spoke routing under stress tests, because packets take the shortest route available. If one path fails, traffic reroutes rather than dropping. Speed depends on the two endpoints, not on how busy a shared server is.
5. Phát trực tuyến và tải torrent
Avast VPN: It reaches Netflix, Disney+, and Amazon Prime Video often enough to be useful, with streaming optimized servers and torrenting servers on the list. Results are inconsistent though. Hulu and BBC iPlayer are the usual failures.
Vảy đuôi: Not built for this at all. There is no catalogue of exit locations to pick from, so geo-unblocking Prime Video is off the table. An exit node at home can let you watch your own country’s services while travelling.
6. Platforms and Device Support
Avast VPN: Windows, Mac, Android, iOS, and Android TV are covered across multiple platforms. One subscription runs on 10 machines at once. Linux and router installs are not supported.
Vảy đuôi: The list of supported operating systems is longer, adding Linux, routers, containers, and Apple TV. Hardware that cannot run the client, like a printer, joins through subnet routers instead. The free tier allows 100 devices.
7. Dễ sử dụng và cài đặt
Avast VPN: Download, install, sign in, press connect. Smart VPN mode adds simple rules so protection turns on by itself on a public network. Nothing here needs technical knowledge.
Vảy đuôi: Installing the tailscale app is quick, but the concepts are not. New users have to understand ACLs, exit nodes, and a subnet router before the network does what they want. A developer will feel at home. A relative asking for “the VPN thing” will not.
8. Access Control and Remote Access
Avast VPN: There is none to speak of. You cannot reach your home computer from the office, and there is no split tunneling to send some apps outside the tunnel. It protects a session, it does not connect resources.
Vảy đuôi: This is the entire point of the product. A web dashboard controls users, devices, and permissions, and you can create groups with their own rules. Sharing a single machine with an outside collaborator takes one invite link.
9. Support and Documentation
Avast VPN: A large help site and ticket system sit behind the product. Reviewers are blunt about the quality, calling the responses slow and generic. Billing questions draw the most complaints.
Vảy đuôi: Documentation is the real support channel, and it is written for people who read code. Free users get email help during business hours only. You can file bugs publicly, which suits technical teams more than casual buyers.
10. Định giá & Chi phí
Here is how the plans line up.
| Gói cước | Avast VPN | Cân đuôi |
|---|---|---|
| Miễn phí | Phần mềm diệt virus miễn phí (không cần VPN) | Personal: $0 Free Forever |
| Vé vào cửa đã trả phí | Gói bảo mật cao cấp: 49,99 đô la/năm đầu tiên | Gói Personal Plus: 5 đô la/tháng |
| Hạng cao nhất | Gói cao cấp: 49,99 đô la/năm đầu tiên | ❌ Không được liệt kê |
| Billing terms | Chỉ hàng năm | Hàng tháng |
Avast VPN: You are buying a security bundle, not a lone vpn service. That is fine value if you want antivirus too, and poor value if you only want the tunnel. The 60 day free trial softens the risk of getting it wrong.
Vảy đuôi: Free forever for personal use is hard to argue with. Most home users never leave that tier. Costs only appear when a company adds seats.
Các kịch bản khác nhau
| Nếu bạn cần… | Chọn | Tại sao |
|---|---|---|
| To hide your ip address | Avast VPN | Real server exits in 34 countries |
| Zero budget | Cân đuôi | Free forever for personal use |
| Reach your home PC remotely | Cân đuôi | Mesh network between your machines |
| Phát trực tuyến và tải torrent | Avast VPN | Dedicated streaming and P2P servers |
| Team access controls | Cân đuôi | Identity-based permissions and groups |
| Thiết lập thân thiện với người mới bắt đầu | Avast VPN | One button, no networking knowledge |
💰 Ngân sách của bạn
Tailscale costs nothing for personal use, which is hard to beat. Avast asks $49.99 for the first year of security software that includes the VPN.
🔌 Bộ công nghệ của bạn
Running a home lab, a NAS, or cloud boxes? Tailscale ties them together, and other clients join the same flat network as you add them.
🔐 Your Network Security Goals
If network security means locking down who reaches which internal resource, Tailscale fits. If it means encrypting café wi fi and stopping dns leaks, Avast fits.
🎓 Trình độ kinh nghiệm của bạn
Avast asks nothing of you beyond a password. Tailscale is basically WireGuard with a friendly control layer, and it still rewards people who read documentation.
🆓 Dùng thử và bản demo miễn phí
Avast gives 60 days but wants card details first. Tailscale gives a permanent free tier with no card at all, so trying it costs you an evening.
🛟 Các tùy chọn hỗ trợ
Neither wins here. Avast has a ticket desk people complain about, and Tailscale offers business-hours email unless you pay for priority help.

Những điều mà bài đánh giá của chúng tôi chưa đề cập
We looked at these products from the angle of a home user and a small team. We did not benchmark enterprise rollouts, Kubernetes deployments, or bulk licensing. One thing worth flagging: plenty of people find Avast SecureLine already installed on a computer because it arrived bundled with other Avast products, and that is a support câu hỏi rather than a buying question. Features change, so treat every figure here as a September 2026 snapshot.

🏆 WINNER: AVAST VPN
Avast VPN takes 4 of 8 categories and the higher overall score at 3.7.
Phù hợp nhất cho: Public wi fi protection, hiding your location, streaming abroad, non-technical households
Avast wins on the scorecard because it does the job people actually shop for. Most readers who type a VPN query want a masked ip address and safe browsing on shared wi fi, and Tailscale does not offer that out of the box.
That said, the win comes with an asterisk. The Jumpshot history and the 2024 FTC penalty are real, and no independent audit exists to reassure you. If a clean privacy record is your first filter, look at audited names on the usual best vpns lists instead.
Tailscale is the better engineered product, but it answers a different question. Pick it when you want your own machines on one private network and nothing more.

Câu hỏi thường gặp
Avast VPN có thực sự hiệu quả không?
Yes. It encrypts your session, masks your location, and blocks dns leaks. Speeds hold up nearby and sag on far servers, so it is a good vpn for casual use.
Avast SecureLine VPN có an toàn để sử dụng không?
The encryption is sound. The trust question is harder, since the parent company paid a $16.5 million FTC penalty in 2024 and has never published an audit.
Bạn có thể sử dụng Tailscale như một VPN không?
Partly. Set one of your devices as an exit node and your traffic routes through it. You still cannot pick a country the way a commercial provider allows.
Tailscale khác với VPN thông thường ở điểm nào?
A normal VPN sends your traffic to a rented server. Tailscale connects your machines to each other instead, so nothing passes through company infrastructure.
Tailscale có miễn phí cho mục đích sử dụng cá nhân không?
Yes. The Personal plan is $0 free forever and covers up to 100 devices. Install Tailscale on each one, sign in, and the tailnet builds itself.
