A nonprofit service with premium efficiency

Proton VPN stands out for 2 most important causes: it is one of many solely digital personal networks (VPNs) to incorporate a free plan with no information limits, and it is one of many few providers majority-owned by a nonprofit. It is the very best VPN in each of these classes, and it makes a powerful case for being the very best general.

Even if you happen to do not care in regards to the work of the Proton Basis, Proton VPN is a service price utilizing. It is simple to put in and handle, runs just like the wind and meets excessive requirements for safety and privateness. It has extra IP areas in Africa than any of its opponents. It is even trying towards the longer term by working towards full IPv6 help.

In brief, Proton VPN will get our enthusiastic advice, particularly for torrenting (which it helps on virtually each server). It isn’t excellent — the apps for Apple techniques lag behind their Home windows and Android counterparts, and the free servers may be noticeably sluggish — however the cons pale compared to the professionals. We’ll get into all of it under.

Editor’s observe (7/25/25): We’re within the technique of revamping our VPN protection to supply extra in-depth, actionable info and shopping for guides. Our suggestions, and all the data on this web page, are topic to alter because the replace continues. Take a look at our revamped ExpressVPN review and NordVPN review to see the brand new route, or be taught extra about how we test VPNs.

Desk of contents

Findings at a look

The desk summarizes what we discovered whereas reviewing Proton VPN, each good and dangerous. Preserve it open in a tab when you comparability store for a VPN.

Putting in, configuring and utilizing Proton VPN

This part explains the way it feels to run Proton VPN on the varied platforms it helps. As a rule, it isn’t tough. Proton VPN has extra options than ExpressVPN, and a few them would possibly journey up new customers, however you’d have to actually scrounge to seek out an precise inconvenience to complain about.

Home windows

Proton VPN installs simply on Home windows — you will have to grant it permission to make adjustments, however that is it. As soon as you’ve got signed in on the app, you will attain probably the greatest interfaces we have tried on a VPN. The server community is straight away seen as each an inventory and map, and the situation search bar, join button and main options are all laid out across the similar window.

It is actually wonderful how a lot you may attain from the launch window with out something feeling cluttered. They even squeezed in keyboard shortcuts for the search subject. We additionally love that settings open in the identical window, since coping with each the principle VPN app and a separate preferences panel can get annoying. Our solely actual gripe is that there needs to be a better solution to regulate the scale of the map.

Mac

The desktop app for Mac is not fairly as deftly laid out because the Home windows app. You’ll be able to attain a lot of the vital options from the principle window, together with Profiles, NetShield, Safe Core servers and the kill swap. Nonetheless, there is not any longer a solution to filter out an inventory of the P2P or Tor servers, besides by digging via the Profile controls. On the plus facet, you may regulate the scale of the map, so it is now a viable different to the server listing.

The opposite preferences are hidden within the menu bar — go to Proton VPN > Settings to achieve them. They’re specified by 4 tabs, and should not take greater than a minute to undergo at setup.

Android

The Android app takes the identical design cues because the Home windows app, and works as properly. 4 tabs alongside the underside swap between the house display screen, the nation listing, Profiles and all different settings. You’ll be able to search the listing of nations by tapping the magnifying glass on the top-right. In one other good contact, tapping the dots by any digital location will inform you the place the server is bodily positioned.

Android customers get some nifty unique Profiles, together with “anti-censorship,” which mechanically connects to the quickest nation apart from the one you are in. The Settings tab is a single menu with subheadings and no pointless complication.

iOS

Proton VPN for iPhone and iPad seems to be virtually the identical because it does on Home windows and Android, however with a number of the similar drawbacks discovered on Mac. The server listing is extra cluttered, and as soon as once more there is not any straightforward solution to sift out the P2P and Tor areas.

The Settings tab places all of the function descriptions within the open, which makes it look denser than it’s. However these are minor quibbles — that is nonetheless a VPN that is very straightforward to activate and neglect about.

Browser extensions

Proton VPN has browser extensions for Chrome and Firefox. These function de facto cut up tunneling, as connecting via the extension protects solely browser site visitors; every little thing else goes unprotected. You’ll be able to cut up the tunnel additional by setting the VPN to not work on sure URLs (not like the opposite apps, you need not know the IPs of these websites).

Proton VPN pace check: Impacts of VPN Accelerator

We used Ookla’s Speedtest app to find out how a lot Proton VPN drags on a person’s latency, measured in milliseconds (ms), and obtain and add speeds, measured in megabits per second (Mbps). Collectively, these three stats present whether or not a VPN will noticeably decelerate your web, particularly throughout demanding duties.

We had excessive hopes for Proton right here due to its VPN Accelerator expertise, which runs VPN communications throughout a number of parallel tracks to course of every little thing quicker. It did not disappoint — for probably the most half. Though obtain speeds did not attain the heights we saw from ExpressVPN, Proton VPN’s shopping efficiency nonetheless seems to be glorious practically throughout the board.

To decide on our areas for the check, we checked Proton VPN’s listing of smart routing servers, which use servers in a single nation to simulate IP addresses in one other. Virtually all of the good routing servers are based mostly in 5 cities: Miami, London, Marseille, Bucharest and Singapore. We ran these checks on a Mac utilizing the automated protocol setting.

Proton VPN seems to be excellent in that desk. Its common obtain pace was 88 p.c of our unprotected speeds. To place that in perspective, if you happen to began with 30 Mbps down (about half what we get) and related to any Proton VPN server, you’d virtually definitely nonetheless have a quick sufficient connection to stream in 4K.

Observe the “virtually” — Proton VPN did drop noticeably on its French server in Marseille. It isn’t unusual for considered one of a VPN’s information facilities to have bother whereas the others work high quality, and you may often repair the issue by simply disconnecting and reconnecting. Simply observe that whereas drops to about 75 p.c of your obtain pace are uncommon, they are not inconceivable.

Proton VPN safety check: Watertight protocols

After we discuss VPN safety, we’re actually speaking about reliability. Can this VPN set up an encrypted tunnel and transmit all of your info via it, each time, with out leaks or failures? With Proton VPN, we’re glad to say the reply is sure; we probed its safety and located no cracks to talk of. Learn the part under for specifics.

Proton VPN protocols: WireGuard, OpenVPN, IKEv2 and Stealth

Proton VPN makes use of 4 VPN protocols to speak between your units, its servers and the web. Three of them (WireGuard, OpenVPN and IKEv2) are widespread selections with no severe flaws so long as they’re carried out thoughtfully. The fourth, Stealth, is an obfuscation protocol it is best to solely use if the opposite three are blocked.

• OpenVPN is probably the most safe possibility. With out getting too technical, OpenVPN encrypts its backend features in addition to the information itself, which leaves it with no apparent vulnerabilities. It could possibly additionally talk utilizing the identical ports as widespread HTTPS site visitors, so it is arduous to dam.

• WireGuard is extra environment friendly than OpenVPN, each in its supply code and the cryptography it makes use of. It usually requires an trade of fastened IP addresses, however the Proton VPN implementation overwrites these IPs with randomized addresses, reducing the safety danger.

• IKEv2 is a secure selection that is often quicker than both OpenVPN or WireGuard. You most likely will not use it until it occurs to come back up when you’ve set the protocol to Sensible. As such, it is on the best way to being phased out of Proton VPN.

• Stealth is exclusive to Proton VPN, although its perform isn’t. It is bought the identical structure as WireGuard, however provides one other TLS tunnel to evade community blocks that catch VPN site visitors. That further encryption slows it down, so we do not advocate utilizing it until the opposite three protocols do not work.

The primary possibility on the app, known as “Sensible,” isn’t a protocol — it means your VPN shopper selects the protocol that will provide you with the very best speeds in your present server. Since all 4 protocols are secure, there is not any draw back to utilizing the Sensible setting more often than not.

Leak check

We used AirVPN’s IP leak tool to verify all 4 of Proton VPN’s protocols for DNS and WebRTC leaks. Proton VPN makes use of its personal DNS servers to scale back the danger of sending unencrypted requests, however since leaks are nonetheless doable, we examined utilizing a easy methodology: checking our seen IP deal with earlier than and after connecting to the VPN.

Regardless of testing a number of areas over three days, we by no means noticed our actual IP deal with present up on the software. This held true even outdoors the Safe Core server listing, the place information facilities might need been managed by third events. It isn’t excellent proof, nevertheless it’s an excellent signal that Proton VPN enforces a constant safety regime on all its servers.

We additionally used BrowserLeaks to verify for WebRTC leaks. These are primarily a problem on the browser facet, however a VPN is doubly vital in case your browser occurs to be leaking. We enabled WebRTC on our browser and examined the identical set of Proton VPN servers with out springing any WebRTC leaks.

Proton VPN and IPv6

Proton is engaged on making its complete VPN appropriate with IPv6 addresses. If a VPN that is solely configured for IPv4 has to resolve an IPv6 deal with, it could trigger a leak — that is why most VPNs, even the very best ones, block IPv6 altogether. That stated, the entire web will run on IPv6 sooner or later, so it is good to see Proton VPN main the pack.

Up to now, IPv6 is mechanically enabled on Proton VPN’s Linux apps and browser extensions, and may be optionally activated on its Android app. The Proton VPN apps for all different platforms nonetheless block IPv6 site visitors, however this could hopefully change quickly.

Encryption check

Even when a VPN’s protocol selections are stable, it is doable for particular person implementations of these protocols to fail. We used WireShark, a packet inspector app, to check whether or not Proton VPN’s encryption labored it doesn’t matter what settings have been in place. We’re glad to say we by no means noticed plaintext as soon as.

How a lot does Proton VPN price?

To get full entry to Proton VPN, you will want a Plus subscription, which prices $9.99 per thirty days. You’ll be able to knock off half that value by subscribing for a full 12 months and paying a lump sum of $59.88, figuring out to $4.99 per thirty days. A Plus account with Proton VPN additionally provides you free entry to each different Proton app.

You can even pay $107.76 prematurely to subscribe for 2 years, a mean of $4.49 per thirty days — maybe extra handy, nevertheless it would not prevent a lot. The one-year plan is the very best worth, although it is also good that you do not have to pay via the nostril for just one month. There is a 30-day, money-back assure on all plans.

Proton VPN is currently offering Engadget readers an exclusive deal that gives a 12-month plan for $47.88 ($3.99 per thirty days) and a 24-month plan for $81.36 ($3.39 per thirty days). Learn more about it here. One last possibility is the Proton Limitless subscription, mentioned within the “facet apps and bundles” part under.”

The Proton VPN free plan

Proton VPN is without doubt one of the finest free VPNs in the marketplace proper now. No different VPN backed by as a lot expertise and common sense has a free plan with no information limits. As an alternative of capping how a lot information you need to use per thirty days, Proton VPN restricts which servers free customers can entry, limiting them to 5 international locations: america, Japan, the Netherlands, Poland and Romania.

The irritating half is which you can’t select which of those servers you utilize; Proton VPN simply auto-connects to whichever one is the least burdened. A Proton consultant instructed us that this alteration goes together with enhancements to the choice algorithm, higher load balancing and the addition of the Poland and Romania areas. Additionally it is doable to strive for a greater connection by clicking “change server.”

The very fact stays, although, {that a} free Proton VPN plan is ineffective for unblocking content material in particular areas — however this can be by design. The free plan appears extra aimed towards privateness and anonymity than streaming, and the position of the free areas close to Russia and China displays that. Free Proton VPN plans do not sacrifice any important security measures.

Proton VPN facet apps and bundles

Proton VPN’s most important bundle is Proton Limitless, which will get you all six Proton merchandise in a single bundle: VPN, Mail, Drive, Calendar, Pockets and Cross. This prices $12.99 for a month, $119.88 for a 12 months ($9.99 per thirty days) and $191.76 for 2 years ($7.99 per thirty days). We cannot be going in-depth on any of them on this assessment, however here is a fast rundown of every.

• Proton Mail: An end-to-end encrypted e mail service. Proton can nonetheless see a Mail person’s actual IP deal with, however cannot learn any of their messages.

• Proton Drive: Encrypted cloud storage. As with Mail, Proton can determine customers, however cannot learn any of the content material they retailer.

• Proton Calendar: An encrypted scheduling app with occasions and reminders.

• Proton Pockets: A self-custody pockets for storing Bitcoin unconnected to any trade.

• Proton Cross: A password supervisor that generates, shops and autofills passwords for on-line accounts.

Even if you happen to solely want two of the six, Proton Limitless saves you cash. Separate month-to-month subscriptions to Proton VPN and Proton Mail would price a complete of $14.98, so you’ve got already knocked off $2 per thirty days. That will increase if you happen to’re capable of decide to a 12 months prematurely.

Shut-reading Proton VPN’s privateness coverage

Proton’s privateness coverage is available in two elements: the general Proton policy and the shorter coverage specific to Proton VPN. We’ll cowl them in that order.

Common Proton privateness coverage

Proton tracks person exercise on its product web sites utilizing its personal advertising instruments; the information set collected doesn’t embody IP addresses. It retains an e mail deal with related to every person’s account, nevertheless it’s not allowed to attach IP addresses (and thus identities and areas) to these emails until the person breaches the phrases of service.

Chances are you’ll rightly ask how Proton would know a person is abusing considered one of their providers if they do not maintain exercise logs. The reply is that logs aren’t wanted; most types of abuse may be detected in different methods and noticed in actual time. For instance, if somebody used a Proton VPN server to launch a DDoS assault, the group might examine that server and discover the hacker whereas the assault was nonetheless ongoing.

The coverage goes on to listing the 5 third-party information processors Proton makes use of (Zendesk, PayPal, Chargebee, Atlassian and Stripe), none of whom are allowed to retailer buyer exercise information. Proton cautions that it’s going to share what information it does have in response to unblockable requests from the Swiss authorities, however not “till all authorized or different cures have been exhausted.” That is commonplace for a VPN that desires to stay in enterprise, and the transparency report exhibits the corporate does certainly combat court docket orders when it could.

Proton VPN privateness coverage

Proton’s VPN-specific privateness coverage is kind of brief. It states that Proton can’t log person actions or identifiable traits of units related to the VPN, can’t throttle web connections and should lengthen full privateness and safety to free customers.

In a single sense, a privateness coverage requires you to take the VPN supplier at their phrase, nevertheless it’s harmful for an organization to make guarantees they do not intend to maintain. The coverage is legally binding, and breaking it’s grounds for a lawsuit. Proton VPN’s succinct no-logs coverage is subsequently an ideal signal. It is also been confirmed a number of instances by a third-party audit, most lately in July 2024.

Can Proton VPN change your digital location?

Testing a VPN’s capacity to masks a person’s location is not advanced — all you want is a streaming subscription. We related to 5 check areas and tried to unblock Netflix with each. If we managed to entry the positioning, and noticed totally different exhibits than these on the American library, we concluded that the situation had masked us efficiently.

Proton VPN handed the check each time in all 5 areas. The one hiccup got here in Romania, which we selected as a result of it is one of many free areas. The app related us to a free server, which was too sluggish to load Netflix; after we selected a paid server, the issue disappeared.

Investigating Proton VPN’s server community

Proton VPN’s free plan consists of servers in 5 areas: the Netherlands, Poland, Romania, america and Japan. If you join as a free person, you will be mechanically related to whichever location is quickest.

A paid plan opens up the total community of 154 servers in 117 international locations and territories. The menu consists of an enormous number of African areas, greater than any VPN we have examined in a while. The Center East, together with central and southern Asia, are additionally properly represented, and U.S. customers will discover 20 totally different areas to select from.

Remember the fact that about two-thirds of those server areas are digital, which means they are not bodily positioned the place they declare to be. This consists of all of the African servers besides South Africa and Nigeria; all of the South American servers besides Brazil, Colombia and Argentina; and all of the Center Japanese servers besides Turkey, Israel and the UAE. A majority of the areas in Asia are additionally digital, together with South Korea, India, Thailand, Indonesia and the Philippines.

To be clear, digital areas can cover your IP deal with simply in addition to bodily ones. It is solely an issue if you happen to’re anticipating the form of efficiency, significantly by way of latency, that you simply get from a close-by server. Fortunately, Proton VPN provides you quick sufficient obtain and add speeds that distance should not be an issue.

Options of Proton VPN

Proton VPN has a lot of further options that transcend commonplace VPN performance. We have already talked about the Stealth protocol and IPv6 help. On this part, we’ll cowl a further 5 options that is likely to be of curiosity.

NetShield advert blocker

Proton VPN’s built-in advert blocker is named NetShield. It is out there on the principle UI web page, and has two settings: one which blocks solely malware websites, and one which blocks websites related with malware, adverts and trackers. The stronger function is on by default.

NetShield works by checking any DNS requests in opposition to a database of internet servers identified to host malware, inject adverts or connect cross-site trackers to your shopping session. The DNS-blocking method means it isn’t able to blocking adverts served from the identical area that hosts them — so no blocking YouTube video adverts. On the optimistic facet, it means NetShield works throughout your complete gadget, not simply in your browser.

NetShield additionally shows a operating whole of what number of of every type of interference it is blocked. It catches most banner adverts, however since you may’t customise the blocklist in any means, it is best when mixed with one other browser-level advert blocker.

Safe Core servers

Here is an fascinating one. Safe Core is a type of a typical function referred to as double VPN or multi-hop VPN, during which a connection runs via two VPN servers earlier than being decrypted. If one server fails or will get compromised, the opposite server retains your connection personal.

Proton VPN takes this a step additional. If you activate Safe Core, your connection will nonetheless finish at your chosen server location — however earlier than that, it is going to journey via a chosen server in Iceland, Sweden or Switzerland. Just a few touches make Safe Core servers extra dependable than the common VPN node:

• All three international locations are secure jurisdictions, with consumer-friendly privateness legal guidelines and courts sympathetic to privateness claims.

• Safe Core information facilities are locked down bodily; for instance, the Iceland location is a refitted army base, and the Sweden location is actually underground.

• Proton owns and operates all Safe Core areas itself, with no leases or third-party managers.

Virtually no different VPNs pay as a lot consideration to bodily safety as Proton VPN does with this function. The second hop makes Safe Core connections slower on common, nevertheless it’s price it in case you have one thing particularly delicate to do on-line.

Kill swap

Proton VPN features a kill swap, a regular function. When lively, a kill swap cuts off your web every time your connection to the VPN drops. This implies you are by no means in peril of leaking your actual id or location, even for a second. It additionally protects you in opposition to the TunnelVision exploit, which requires the hacker to make a pretend VPN server.

Cut up tunneling

Cut up tunneling is included on the Home windows and Android apps, however customers on different units can entry it via the browser extension. With cut up tunneling, some apps or web sites get on-line via the VPN, whereas others keep unprotected.

Proton VPN permits cut up tunneling by each app and IP deal with. This grants you a exact stage of management over your cut up, so long as you understand the IP of every web site you are putting on the listing (you’ll find that out utilizing DNS checker).

Torrenting servers and port forwarding

Proton VPN is without doubt one of the finest VPNs for torrenting. It restricts torrenting to P2P servers, however practically each server on the listing is a P2P server — solely Safe Core servers and a few free servers do not allow torrenting. Mix that with the truth that it maintains 96 p.c of your add speeds on common, and it is best to have few issues utilizing a torrenting shopper.

It additionally has some help for port forwarding, which might enhance torrenting pace. Home windows and Linux customers can allow it with a easy toggle, which offers an lively port quantity for configuring personal servers. Mac customers can arrange port forwarding via guide OpenVPN or WireGuard configurations.

Tor over VPN

A handful of Proton VPN servers route you on to the Tor community after encrypting your connection. Whereas related to considered one of these Tor over VPN servers, that are marked with TOR of their names and an onion image, you’ll open .onion hyperlinks on a standard browser.

That is extra than simply handy — Tor over VPN is the most secure solution to entry the darkish internet. With the VPN as an middleman, you are by no means connecting to Tor with your individual IP deal with, so malicious node operators cannot see your actual id. For optimum privateness, use Tor Browser to create your Proton VPN account, so that you’re by no means uncovered at any level within the course of.

Proton VPN has Tor servers in six international locations (the U.S., France, Switzerland, Sweden, Germany and Hong Kong). Every simply has one Tor server, besides america, which will get two. Tor over VPN is supported on all platforms, nevertheless it will not work on Mac or iOS until you’ve gotten the kill swap enabled.

Profiles

A “profile” on Proton VPN is a gaggle of pre-established settings you need to use to rapidly configure the VPN for a specific activity. Two profiles can be found from the beginning: Quickest, which connects to the quickest server, and Random, which all the time connects to a unique server. You’ll be able to create extra profiles by toggling 4 settings:

• Characteristic: The kind of server used. Select from Normal, Safe Core, P2P or Tor over VPN.

• Nation: The nation to which the profile connects.

• Server: A server inside that nation. You can even choose “quickest” or “random.”

• Protocol: Which VPN protocol the profile will use. “Sensible” may be chosen.

For example, say you need to watch a TV sequence that is solely out there on Netflix in Canada. You can create a profile known as “Netflix Canada” that connects to the quickest Canadian server with only one click on. We would name profiles situationally helpful, however they’ll save a number of time if you happen to usually carry out the identical motion in your VPN.

Proton VPN buyer help choices

We went to Proton VPN’s FAQ pages with two questions that got here up whereas researching different sections: which of Proton VPN’s servers are managed by third events, and why do sure server areas (like Marseilles) run sluggish regardless of the app exhibiting a light-weight load?

You’ll be able to entry the assistance middle via any of Proton VPN’s apps, or by going on to the web site. Articles seem like organized into six classes. Oddly, clicking any class button solely exhibits you a handful of the articles in that part — for instance, the Troubleshooting class seems to be prefer it solely has 5 articles. In case you kind “troubleshooting” into the search bar, although, you will see dozens pop up. There are even some sections, like Billing, that do not seem on the principle web page in any respect.

It has the texture of an internet site replace that wasn’t adequately introduced consistent with the majority of the help content material. Till Proton fixes it, simply use the search bar for every little thing. The articles themselves are well-written, give or take some stilted English.

Getting fast assist

We could not discover written solutions to our questions on possession and server load, so we turned to stay chat. Free customers ought to remember that stay chat help is just out there on paid accounts, however there is a pretty lively subreddit at r/protonvpn the place Proton employees regularly submit.

Dwell chat isn’t intuitively positioned on protonvpn.com. We lastly discovered it by scrolling all the best way to the underside of the principle web page, solely to be instructed no person was on-line to assist in the intervening time — stay chat is just accessible from 9 AM to midnight Central European Time (CET). We submitted our query in regards to the Marseille servers as an e mail ticket as a substitute.

This half was straightforward, no less than, as the shape helpfully populated our system info. We additionally bought a immediate response inside 24 hours. We ended the interplay there, as we weren’t capable of reproduce the sluggish conduct on the French server areas, nevertheless it’s good to know the group will reply rapidly.

Proton VPN background verify: The CERN origins of Proton AG

Proton VPN launched in 2017, however its group’s expertise goes again a lot farther. The founders of its dad or mum firm, Proton AG, met whereas working at CERN in Switzerland, and the corporate stays below Swiss jurisdiction.

Their first product, Proton Mail, went live in 2014 after a profitable crowdfunding marketing campaign, and claims to have 100 million customers immediately. Proton VPN was Proton AG’s second mission. Like Proton Mail, it consists of a free plan supplemented by paid upgrades.

Since then, Proton has launched a number of extra merchandise: Proton Calendar in 2020, Proton Drive cloud storage in 2022 and the Proton Cross password supervisor in 2023, every designed round utilizing end-to-end encryption to make person information inaccessible.

The Proton Basis

Proton announced in 2024 that almost all of its shares had been acquired by the Proton Basis, a nonprofit whose solely goal is to manage Proton inventory. Amongst different advantages, this prevents it from being bought by anybody who disagrees with its mission. To promote to an objectionable dad or mum firm, your complete board of trustees must agree, which feels unlikely based mostly on Proton’s monitor document.

All through Proton’s historical past, we solely discovered two incidents severe sufficient to touch upon, and solely considered one of them involved Proton VPN. We’ll cowl them each under.

ProtonMail legislation enforcement collaboration allegations

On the web page that hosts its annual transparency report, Proton states brazenly that it “could also be legally compelled to reveal sure person info to Swiss authorities” (see the Privateness Coverage part of this text for extra on exactly what info that describes). In 2021, the company admitted it had given Swiss police (appearing on a French warrant) a ProtonMail person’s IP deal with and gadget logs. The police arrested the person, a French environmental activist.

Whereas that is unnerving for privacy-minded customers, there are some vital contextual points to think about. Most significantly, ProtonMail isn’t ruled by the identical coverage as Proton VPN. On the time the case unfolded, Swiss legislation obliged all email companies to adjust to court docket orders from Swiss authorities handy over information. VPNs aren’t subject to those retention requirements.

Right this moment, Swiss e mail corporations have been reclassified in order that they’re additionally exempt from information retention necessities, thanks partially to a policy change Proton fought for. A consultant from Proton confirmed that “below Swiss legislation, we aren’t obligated to save lots of any person connection logs.” It is also reassuring that, regardless of complying with the subpoena, Proton wasn’t able to turn over the contents of any emails.

Alleged WireGuard reminiscence vulnerability

In January 2025, researchers at Venak Safety alleged that Proton VPN lacks memory protection for keys generated below the WireGuard protocol, which could let hackers scrape the keys and decrypt intercepted communications. Proton responded to Venak in a blog post, which a Proton consultant confirmed stays their official response to the allegations.

In brief: the Venak article solely demonstrates that it is doable to view public keys, not personal ones. This is not a lot of a bombshell, on condition that “public” is true there within the title. However uneven encryption — the sort utilized by VPN protocols like WireGuard — requires each keys to decrypt any messages. Even when a hacker have been capable of get ahold of a personal key, they doubtless would not be capable of use it for something. WireGuard incorporates excellent ahead secrecy by default, altering session keys typically sufficient that any given key’s out of date by the point it is stolen.

Last verdict

In brief, we’re ready to advocate Proton VPN to virtually anyone. Whether or not you are primarily involved with safety, streaming or one thing else, chances are high good that you’re going to be glad. The one severe downsides are that the long-term plans are overpriced and that it is arduous to get stay tech help if you happen to stay outdoors of Europe.

It is also our unqualified decide for the very best free VPN, however with the caveat that it is a dangerous selection for anybody who wants to decide on particular server areas. If all you care about is staying hidden out of your ISP and advertisers, Proton needs to be your first selection.
