1. Mạng máy chủ
Truy cập Internet riêng tư: PIA operates 35,000 servers across 91 countries. That includes coverage in all 50 US states, which is helpful for accessing location-specific content. PIA uses RAM-only servers that wipe data on every reboot. The network also includes virtual servers for regions with limited infrastructure.
Bitdefender VPN: Bitdefender offers over 4,000 servers in 54 countries. The server list is smaller, and there are no dedicated streaming-optimized servers. Performance drops on distant server locations, especially in Japan and Úc.
2. Privacy and Logging
Truy cập Internet riêng tư: PIA has a strict no-logs policy verified by Deloitte through multiple audits. The privacy policy clearly states that PIA does not collect browsing history, DNS queries, connection timestamps, or bandwidth logs. PIA also publishes quarterly transparency reports showing legal requests received.
Bitdefender VPN: Bitdefender states it does not log web traffic or browsing history. However, the privacy policy is vague and does not have a separate logging policy for traffic logs from the VPN. Some technical data is collected for fraud prevention. There has been no independent audit of the VPN logging practices. Bitdefender does offer advanced features like an ad blocker and anti-tracker.
⚠️ Cảnh báo: Bitdefender VPN is powered by Hotspot Shield’s infrastructure. Your data passes through third-party servers, which adds a layer of complexity to privacy claims.
3. Encryption and VPN Protocols
Truy cập Internet riêng tư: PIA supports both the OpenVPN protocol with AES-256 encryption and WireGuard with ChaCha20. Users can customize the encryption level and choose between protocols manually. This level of control is rare among VPN apps.
Bitdefender VPN: Bitdefender uses AES-256 encryption and supports WireGuard, OpenVPN, and the proprietary Catapult Hydra protocol. The Hydra protocol is designed for speed but offers less transparency than open-source alternatives. Users can switch between protocols in the app settings.
4. Công tắc ngắt khẩn cấp
Truy cập Internet riêng tư: PIA provides two types of kill switches on Windows and macOS. The regular kill switch blocks internet traffic when the VPN connection drops. The advanced kill switch blocks all traffic unless connected to PIA, even before the app launches.
Bitdefender VPN: Bitdefender includes a standard kill switch that shuts down internet traffic if the VPN connection drops. It works reliably but lacks the advanced always-on mode that PIA offers. There’s no app-specific kill switch option.
5. Hiện tượng phân nhánh đường hầm
Truy cập Internet riêng tư: PIA’s split tunneling lets you exclude specific apps and IP addresses from the VPN tunnel. You can also control DNS requests separately. This gives power users fine-grained control over which browser traffic goes through the VPN connection.
Bitdefender VPN: Bitdefender supports split tunneling for apps and domains. You can choose which apps use the VPN tunnel and which bypass it. The feature is easy to set up but lacks the IP-level controls that PIA offers.
6. Phát trực tuyến và bỏ chặn
Truy cập Internet riêng tư: PIA has streaming-optimized servers that can access Netflix, Disney Plus, Amazon Prime Video, and BBC iPlayer. However, access varies by server location and may not work consistently on every attempt. PIA also supports port forwarding for incoming connections. Connection speeds are good enough for online gaming on nearby servers.
Bitdefender VPN: Bitdefender VPN can unblock BBC iPlayer and some regional streaming services. However, it struggles with US Netflix, Amazon Prime Video, and Disney+ access. There are no dedicated streaming servers in the server list.
⚠️ Cảnh báo: Neither VPN guarantees 100% access to all streaming services. Streaming platforms regularly update their VPN detection methods.
7. Khả năng tương thích của thiết bị
Truy cập Internet riêng tư: PIA supports Windows, macOS, Linux, Android, iOS, and routers. Browser extensions are available for Chrome and Firefox. PIA also offers a command line app for advanced users. You can protect all your devices with a single subscription.
Bitdefender VPN: Bitdefender supports Windows, macOS, Android, and iOS only. It does not work on Linux devices, routers, Apple TV, or Fire TV Stick. Mobile apps are available on the Apple App Store and Google Play. The 10-device limit may feel restrictive for larger households.
8. Tốc độ và hiệu năng
Truy cập Internet riêng tư: PIA’s average download speed loss is around 49%. Connection speeds are generally sufficient for streaming and web browsing. Performance on Windows using the OpenVPN protocol tends to be better than WireGuard. PIA offers unlimited bandwidth on all plans.
Bitdefender VPN: Bitdefender VPN uses the Catapult Hydra protocol for faster connection speeds on nearby servers. Download speeds are adequate for casual use. However, performance drops noticeably when connecting to distant server locations. Ping times may be higher than dedicated VPN providers.
9. Hỗ trợ khách hàng
Truy cập Internet riêng tư: PIA offers 24/7 live chat and email support. The website includes a knowledge base, guides, and a community forum. Support agents can help in English, French, German, and Romanian.
Bitdefender VPN: Bitdefender provides 24/7 live chat, email, and phone support. The general support team handles all Bitdefender’s products, not just the VPN as a data processor. Email responses may take 30 minutes or more. A knowledge base with Bitdefender’s instructions and how-to guides is also available. Desktop notifications keep you updated on connection times and security events.

What Our Review Didn’t Cover

Câu hỏi thường gặp
Liệu Private Internet Access có an toàn để sử dụng không?
Yes. PIA uses AES-256 encryption and has a no-logs policy verified by Deloitte. The apps are open-source, which means anyone can review the code for security flaws. Many reviewers consider it a top tier VPN for privacy.
Bitdefender VPN có đáng tin cậy không?
Bitdefender is a reputable cybersecurity company based in Romania. The VPN uses AES-256 encryption and does not log web traffic. However, there’s no independent audit of the VPN’s logging practices, and the privacy policy could be clearer.
VPN PIA có thể bị theo dõi không?
PIA encrypts your internet traffic and hides your actual IP address. The no-logs policy means there’s no connection data stored on the servers. This makes tracking very difficult, though no VPN can guarantee absolute anonymity.
Bitdefender VPN có tương thích với Netflix không?
Bitdefender VPN has limited success with Netflix. It can access BBC iPlayer and some regional services, but it often fails to unblock US Netflix and Disney+. If streaming is a priority, PIA or a dedicated streaming VPN may be a better fit.
Which VPN is better for privacy — PIA or Bitdefender?
PIA is the stronger option for privacy. It has open-source apps, a Deloitte-audited strict no-logs policy, and quarterly transparency reports. Bitdefender’s VPN runs on third-party infrastructure and has a less transparent privacy policy.
How many servers does PIA have?
PIA covers 91 countries with 35,000 servers. That’s far more than most VPN providers offer. The network includes a UK server and servers in all 50 US states, making PIA useful for unblocking streaming content and keeping your data private from online threats.
Are there any Private Internet Access deals available?
The best deal is the 2-year plan at $2.03/month. PIA sometimes offers extra months free with long-term plans. All plans include the same features, and there are no identifying data or targeted ads in the app. Check the latest version of PIA’s pricing page for current offers.
What does Bitdefender Premium VPN include?
A Bitdefender Premium VPN review shows it includes unlimited traffic, an ad blocker, anti-tracker, and access to geo restricted content. It connects to your Bitdefender Central account for managing all your devices. The VPN processes data through randomly generated tokens rather than storing user and device IDs directly, which provides some privacy protection.
