Proton VPN is a VPN service that was launched in 2017. It's owned and operated by Proton AG, a Swiss company that also operates Proton Mail, the encrypted email service. Proton VPN has open-source applications on several different platforms, servers located in over 110 countries, and additional features like obfuscation, multi-hop, and DNS filtering.

Our Verdict

8.0 Torrent

Proton VPN is great for torrenting. It lets you download torrents, has no data limit, and keeps your IP address and DNS queries inside the VPN tunnel, ensuring your traffic remains private. However, its kill switch doesn't function properly, as it allows some unencrypted traffic through upon restarting your system. It also lacks anonymity-preserving registration options, as it requires an email address and password to create an account.

Pros
  • Accepts a variety of privacy-preserving payment options.

  • Proper TLS implementation doesn't leave you vulnerable to man-in-the-middle attacks.

  • Doesn't leak your IP address or DNS queries.

Cons
  • Kill switch doesn't work as intended.

  • No registration options that preserve anonymity.

6.2 Security

Proton VPN has acceptable security. It doesn't leak your IP address or DNS queries while you're connected to it, and it has proper TLS implementation, protecting you from man-in-the-middle attacks. However, its kill switch doesn't work correctly, as it leaks some unencrypted traffic upon rebooting your system, which is a concern if you need all your traffic to be encrypted after a restart.

Pros
  • Proper TLS implementation doesn't leave you vulnerable to man-in-the-middle attacks.

  • Doesn't leak your IP address or DNS queries.

Cons
  • Kill switch doesn't work as intended.

8.4 Speed

Proton VPN has fast download and upload speeds, so you can download files quickly with ample bandwidth for 4k video streaming. That said, it has poor latency performance, so it's unsuitable for latency-sensitive tasks like online gaming and won't feel responsive when using the internet in general.

Differences Between Sizes And Variants

Proton VPN has a free tier and a paid Plus tier, which we bought and tested in this review. We also tested Proton VPN Free separately.

PlanMaximum DevicesTorrents (P2P)Country SelectionSpeed ThrottlingSplit Tunnelling

Plus10Yes117NoYes

It's also included in Proton Unlimited, a subscription with all of Proton's services.

Compared To Other VPNs

Proton VPN is a solid choice that's on par with its peers in its security performance. Like the rest, it fails the kill switch test. It also has higher latency than many other VPNs, which is a downside if you're concerned with gaming performance and general responsiveness.

It has several additional security features, like multi-hop and obfuscation, and servers located in over 110 countries worldwide. Its owner, Proton AG, also has a fairly positive reputation among those concerned with privacy.

The kill switch doesn't work as intended, as network traffic leaks outside the VPN tunnel after a reboot. This can be problematic if you're concerned with keeping your traffic encrypted at all times, like if your system freezes and you have to restart it.

    It would be interesting to check if you adjust the treble on the built-in EQ. Would it correct the dip and measure as a better earphone?

    I don’t think their measurements are correct; there’s too much canceling in their measurements. The best of the Sony and Bose NC is on that level. I just checked their review about the Buds2 Pro, and they claim a 50dB cancellation at around 60 Hz, whereas the Rtings review is 35 dB. Cirnacle has some videos about this explaining why many reviews can’t be trusted. Also, measuring is very hard, so there are not even intentionally different results in many cases.

    Also, we can still hope for a firmware update. I could imagine that the poorly polished software causes this weak cancellation.

    Their measurements and opinion about ANC is quite different, see here https://www.soundguys.com/jabra-elite-8-active-review-101055/

    Many reviewers praised the noise isolation that is on par with the latest Sony XD. That’s why I don’t trust reviewers and influencers, only scientific measurements like we see here. I’m very disappointed in these results from Jabra. A cheap Soundcore earbud has a lot better noise canceling. In the left driver, a 20dB lift at the mid-trebble is unbelievable.

    Wow…..just looking at the numbers while comparing the 7 Active to the 8 active, Jabra’s literally ONLY improvement is “our earbuds are tougher”. In fact, overall the numbers show the 8’s as being not improved at all.

    I have bought an Early Access to see this review because I have seen some not-too-reliable measurements on other sites. Rtings review is great as usual. Jabra is a disappointment in many aspects.

    Just created this account to upvote you, my 7 pro pair got damaged, and waiting for this review to buy them or buy the 7 pro again

    By measurement, the 7 Pro is one of the best-sounding earbuds with the most comfortable fit. @RTINGS please include a comparison to this model. The Elite 8 looks more similar to it, but the driver should be better in the Elite 10, also full Dolby spacial audio sounds very promising. If you could describe in detail what to expect would be great.

    Hey mattfysh, As in stands, we have a few other products in our testing queue, so we won’t be able to start testing until the week of the 16th. Keep an eye on our main discussion thread for status updates on the review though! Thanks, Matt

    Thank you for replying; I’ve been waiting for an accurate review since its release. I have seen some measurements, but they are inacurate and not comparable to your consistent data.
