What Our Review Didn’t Cover

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.

最終評決

Surfshark and Bitdefender VPN serve different types of users. Surfshark is a full-featured VPN service with unlimited connections, wide platform support, and strong streaming access. It’s the better standalone VPN pick for most people.

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.

If you need online privacy for all your devices, Surfshark is the clear pick.

よくある質問

Surfshark VPNは信頼できるのか？

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は良いサービスですか？

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の月額料金はいくらですか？

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はNetflixで使えますか？

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は無料で利用できますか？

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.
