1. Encryption and VPN Protocols
Surfshark： Surfshark uses AES-256 encryption across all its apps. It supports WireGuard, OpenVPN, and IKEv2 protocols. WireGuard is the default choice and delivers the fastest download speeds. Surfshark’s Camouflage Mode disguises VPN traffic as regular internet traffic to avoid detection.
Bitdefender VPN： Bitdefender VPN also uses AES-256 encryption. It supports WireGuard, OpenVPN, IPSec, and the Catapult Hydra protocol. Hydra is designed for fast connections but is a proprietary protocol. Bitdefender lacks any obfuscation technology for bypassing censorship.
2. 隐私和无日志政策
Surfshark： Surfshark’s privacy policy states it does not log browsing history, session data, or web traffic. The no-logs policy has been independently audited by both Deloitte and Cure53. Surfshark only retains IP addresses for a maximum of 15 minutes after a session ends. The company is based in the Netherlands.
Bitdefender VPN： Bitdefender says it does not store traffic logs or browsing history. It uses randomly generated tokens and hashed user data for fraud prevention. However, the privacy policy is considered vague by reviewers. Bitdefender is based in Romania, which sits outside the Five Eyes alliance.

Surfshark： Surfshark allows unlimited simultaneous connections. One subscription covers every device in your household. You can install Surfshark on phones, tablets, laptops, smart TVs, routers, and gaming consoles.

5. 流媒体和内容访问
Surfshark： Surfshark can unblock Netflix, Hulu, Disney+, and other popular streaming platforms. Users report buffer-free experiences when connected to nearby servers. The VPN works well for accessing geo-restricted content.

6. 平台支持
Surfshark： The Surfshark app is available on Windows, macOS, Linux, Android, iOS, Android TV, Apple TV, and Fire TV. Browser extensions cover Chrome, Firefox, and Edge. You can also set up Surfshark on routers for whole-network protection.

Surfshark security features include a kill switch and DNS leak protection. Performance can vary based on server distance and network conditions.

9. 客户支持

The latest version of Surfshark’s Windows app includes a favorites system for saving preferred server list entries. You can connect to a UK server or any other location with one click.
Bitdefender VPN： Bitdefender offers 24/7 live chat, email, and phone support. However, the support team handles all Bitdefender products. This means the agents may not be VPN specialists. Email responses can take at least 30 minutes.

我们的评测没有涵盖的内容
This comparison focused on individual and household users. We didn’t test enterprise-level VPN configurations or evaluate how either tool performs in highly censored regions like China or Iran. Long-term speed consistency over months of use wasn’t measured. If you’re managing VPN access for a team of 50+ users, your priorities may differ from what we’ve covered here.

Bitdefender VPN works best as an add-on to your Bitdefender antivirus subscription. If you already pay for Bitdefender security products, the VPN comes at a low extra cost. But as a standalone VPN provider, it falls short of Surfshark on features and flexibility.

常见问题解答
Surfshark VPN值得信赖吗？
Yes. Surfshark has a no logs policy that has been audited by Deloitte and Cure53. The VPN company uses AES-256 encryption and supports the WireGuard and OpenVPN protocol. It is a good VPN for online security and protecting your online activities from online threats. Surfshark encrypted connections keep your data safe even on public Wi-Fi.
Bitdefender VPN好用吗？
Bitdefender VPN is a decent choice if you already use Bitdefender antivirus products. It provides standard VPN features like a kill switch, split tunneling, and ad blocking. However, it lacks advanced features like Linux support, obfuscated servers, and IP rotation that specialist providers offer. It is not a virtual private network built for geo restricted content access.
Surfshark VPN每月费用是多少？
Surfshark pricing starts at $1.99/month on the 2-year Starter plan, $3.19/month on the annual plan, or $15.45 for a single month. All plans include a 30-day money back guarantee and unlimited device connections. You can pay with credit cards, PayPal, Apple Pay, or Google Pay. A Surfshark subscription covers all your devices with no cap.
Bitdefender VPN 能与 Netflix 配合使用吗？
Bitdefender VPN has improved its streaming capabilities. Recent reviews show it can now unblock some Netflix libraries. However, it still struggles with certain platforms compared to Surfshark, which reliably unblocks most major streaming services.
Surfshark VPN可以免费使用吗？
Surfshark offers a 7-day free trial on the Android app and iOS. There is no permanent free plan. After the trial, you need a paid Surfshark subscription. You can install Surfshark on multiple devices during the trial, though the trial limits you to 3 devices. All paid plans come with a 30-day money back guarantee. Tested Surfshark and found it delivers on its claims for most users.
What features does Surfshark offer beyond a standard VPN?
Surfshark offers IP rotation through its IP rotator feature, which changes your virtual IP address at set intervals. You also get a dedicated IP address option, a virtual phone number add-on, and webcam protection on Surfshark’s Windows app. The Alternative ID tool creates a new identity for online signups. These go well beyond standard VPN features that most providers include.
How does Bitdefender VPN handle data and privacy?
Bitdefender acts as a data processor and processes data through its VPN tunnel. It uses randomly generated tokens and hashed user data with device IDs and user and device IDs for fraud prevention. The company does not store traffic logs or browsing history. Bitdefender accepts credit cards, PayPal, and bank transfer for payments. The VPN can automatically connect on untrusted networks, though desktop notifications alert you to connection status changes.
Does Surfshark work in restricted countries?
Surfshark’s Camouflage Mode hides VPN traffic so it looks like normal internet traffic. This helps in countries that block certain websites. Surfshark’s servers include virtual servers in regions with limited coverage. You won’t share the same IP address with other users thanks to the shared IP address rotation system. Surfshark also offers static IP addresses and a dedicated IP add-on for users who need a consistent IP. Atlas VPN was a competitor but has since shut down, making Surfshark an even stronger option in the budget VPN space.
