ProtonVPN Recenzie: Rezulatul expertului
ProtonVPN has excellent security, top-notch privacy features, and a really simple interface, and it maintained fast speeds in all of my speed tests.
ProtonVPN protects user data with 256-bit AES encryption, advanced server architecture, a strict no-logs policy, a kill switch, and much more. ProtonVPN has apps for all major platforms, and it allows 10 simultaneous connections on a single account.
ProtonVPN also has:
- Dedicated servers for torrenting — Works with all major torrenting clients like uTorrent, BitTorrent, qBittorent, and Vuze.
- Dedicated streaming servers (called ‘Plus’ servers) — Able to access popular streaming services like Netflix, Amazon Prime, and Disney+.
- Split tunneling — Allows you to route some of your internet traffic through the VPN and some through your local network.
- An ad blocker — Blocks ads, tracking sites, and malicious websites.
- And a lot more…
ProtonVPN is one of the best VPNs on the market, but there are a couple of things that need improvement. For starters, ProtonVPN isn’t able to bypass internet firewalls — so if you live in or are traveling to a country that restricts the internet, ProtonVPN isn’t a good option (ExpressVPN is the best for that). I’d also like to see ProtonVPN use RAM-only servers so no user data is ever stored on the hard drive, provide 24/7 live chat, and respond to customer support emails quicker.
ProtonVPN has a free plan and monthly and yearly subscription plans that come with a prorated 30-day money-back guarantee.

ProtonVPN Full Review
I spent a few weeks testing, researching, and looking into all aspects of ProtonVPN. And I can safely say that it’s one of the top VPNs on the market.
ProtonVPN has a reputation as being a high-privacy VPN, coming from the same company that makes the ultra-secure, encrypted email service ProtonMail.
And this VPN really does have lots of high-privacy features, along with intuitive user apps, strong streaming and torrenting capabilities, and very fast connection speeds.
ProtonVPN includes all of the essential VPN privacy features, like:
- 256-bit AES encryption. This is one of the strongest encryption algorithms in the world (sometimes called “military-grade” encryption).
- No-logs policy. ProtonVPN doesn’t keep logs of personal information or online activity.
- Kill switch. This feature automatically disconnects you from the internet if your VPN connection fails. Note that ProtonVPN’s in-app kill switch is only available on macOS and Windows. But there are similar features for Android and iOS.
ProtonVPN also has a few extra security features, like:
- Perfect forward secrecy. This changes your encryption key each time you connect to a ProtonVPN server, so if one encryption key is compromised, only the data on that one key is vulnerable (and not any past or future sessions).
- Full-disk encryption. If a ProtonVPN server is compromised, disk encryption keeps all of the data on that server secure and unreadable.
ProtonVPN offers 3 protocols, including WireGuard, IKEv2/IPSec, and OpenVPN. These protocols are available for Android, iOS, and Macs, whereas the Windows app only supports WireGuard and OpenVPN. I love that ProtonVPN has WireGuard, which is a newer protocol with faster speeds than IKEv2/IPSec and OpenVPN — top VPNs like TunnelBear, PrivateVPN, and HMA don’t include WireGuard.
ProtonVPN also has built-in leak protection for DNS, WebRTC, and IPv6. I like how ProtonVPN automatically blocks IPv6 traffic, which is more convenient than competitors like TunnelBear and Private Internet Access that require you to manually block IPv6.
ProtonVPN’s Secure Core server architecture passes your data through 2 servers before it leaves the ProtonVPN network.
This way, if a third party hacks the final destination server, it will only be able to trace your connection back to the Secure Core server (and not your device). ProtonVPN’s Secure Core servers are based in underground data centers in Switzerland, Sweden, and also on a former military base in Iceland.
Secure Core is similar to a double VPN connection — but double VPN connections bounce your data through 2 normal servers in 2 random countries while Secure Core routes your traffic through 2 Secure Core servers, including 1 hyper-secure server that’s in an ultra-secure location, thereby providing even stronger protection. ProtonVPN’s Secure Core servers are more like CyberGhost VPN’s NoSpy servers (that route your connection through servers that are housed at the company’s headquarters in Romania).
Routing your traffic through 2 servers will naturally slow down your speed more than when you’re connected to just one server — when I manually connected to a Secure Core server, websites took 5-6 seconds to load, which is pretty slow. But Secure Core servers are still faster than most competitors’ double VPN features (Perfect Privacy’s double VPN connection took me an average of 10 seconds for websites to load).
I only recommend using this feature if you’re looking to take extra measures to keep your online identity anonymous or if you’re in a high-risk country that may monitor your internet traffic. Even still, ProtonVPN’s Secure Core is an excellent privacy feature that is not available with many other VPNs.
NetShield blocks ads, trackers, and malicious sites. I tested this feature by visiting websites that are usually littered with ads — NetShield blocked every single ad on those websites. These websites were much less cluttered, and the websites even loaded a little faster because there were no more ads.
I really like ProtonVPN’s NetShield tool. It works just as well as IVPN’s AntiTracker tool, and it is better at blocking ads than Surfshark’s CleanWeb and CyberGhost VPN’s ad blocker (ExpressVPN doesn’t even have an ad blocker, but it includes a tracker and malware blocker).
NetShield is no doubt one of ProtonVPN’s best security extras — it doesn’t have the full-featured phishing protection that many antiviruses have, but it blocked all ads and pop-us and prevented me from visiting malicious and tracking websites.
ProtonVPN’s split-tunneling feature lets you include or exclude web browsers, apps, and even IP addresses from the VPN tunnel — this is better than most competitors’ split-tunneling features (ExpressVPN only lets you redirect apps).
However, like most other VPNs, ProtonVPN also supports split-tunneling on Windows and Android only — I’d love to see ProtonVPN add split-tunneling to the Mac or iOS app, but considering that very few competitors provide this feature for Apple users (ExpressVPN has split-tunneling for macOS 10.15 and below, and Private Internet Access supports split-tunneling on macOS 11), I can’t say this is a dealbreaker.
I tested ProtonVPN’s split-tunneling feature by connecting to a US dedicated P2P server and excluding my Chrome browser traffic from the VPN tunnel, and it worked well. It ended up increasing both my browsing and torrenting speeds.
Overall, ProtonVPN’s split-tunneling feature is really good — it does what it says it does, there are no glitches, and it’s easy to set up.
Tor over VPN
ProtonVPN supports The Onion Router (Tor) over VPN on designated servers located in the US, France, Germany, Sweden, Switzerland, Iceland, and Hong Kong.
I like how easy it is to use Tor over VPN with ProtonVPN. All that you need to do is connect to one of ProtonVPN’s Tor servers (identified by an onion icon next to the server), and then all of your traffic is automatically routed through the Tor network.
This lets you surf .onion sites on your own browser (Chrome, Firefox, etc.) instead of downloading the Tor browser. The one drawback is your internet speed slows down significantly (because it encrypts your traffic several times) while connected to the Tor network — it took me more than 15 seconds for websites to load.
Overall, ProtonVPN’s Tor over VPN is an easy and quick way to access the Tor network. Most users won’t need this tool (ProtonVPN’s regular servers are secure for normal browsing, streaming, and torrenting), but it’s an excellent (and very convenient) option for those who do need it.
ProtonVPN has a speed-boosting feature called VPN Accelerator, which increases your connection speeds on distant servers (my speeds were essentially unchanged on local servers). It’s available on all of ProtonVPN’s apps, and it’s easy to find (under the Connection tab in the Settings menu) and easy to turn on (with one click).
VPN Accelerator uses state-of-the-art technology that reduces latency, bypasses congestion on the internet, and shortens the delivery of packet information to improve speeds by up to 400%, according to ProtonVPN’s website, where you can also find more detailed and technical definitions of how the feature works.
But if you aren’t tech-savvy or don’t understand very in-depth internet connection speed processes, all you really need to know is this — VPN Accelerator works!
In my tests, VPN Accelerator provided me with faster speeds than I had without VPN Accelerator on servers located in South America, Europe, and Asia (I’m located in the US). For example, here are my speeds with and without the feature while connected to the same server in Japan.
My download speeds more than doubled when I enabled VPN Accelerator. With the feature, websites loaded in 3 seconds and videos started in about 4 seconds. However, when I turned off the feature, the same websites loaded in 6 seconds and videos began playing in about 5-6 seconds.
Overall, I really like VPN Accelerator — it’s easy to use, it actually works as it’s intended, and I’m not aware of any other provider that has a similar feature.
ProtonVPN Privacy & Security
ProtonVPN is based in Switzerland, which has some of the toughest data privacy laws in the world. Switzerland also doesn’t have any mandatory data retention laws, and it isn’t a part of the 5/9/14 Eyes Alliances (a group of nations that have agreed to share intelligence data).
ProtonVPN also has a strict no-logs policy — it only collects your email address (for communication purposes), payment details (like your name and partial info), and a timestamp of the last login attempt (but it doesn’t include any identifiable information). To remain more anonymous, you can pay with cash or Bitcoin. I also like how ProtonVPN’s no-logs policy has been independently audited and confirmed by an independent third-party — competitors like ExpressVPN have also undergone third-party audits to confirm their privacy policies, and Private Internet Access has even had its no-logs policy tested and confirmed in court (multiple times).
I really like that all of ProtonVPN’s apps are open-source. This means anyone can investigate ProtonVPN’s security. Plus, all of ProtonVPN’s apps have been independently audited and verified for vulnerable security risks — the audits found only “medium” and “low” risks that ProtonVPN quickly resolved.
Like CyberGhost VPN, ProtonVPN issues transparency reports that detail all of the requests it receives for user data (from law enforcement and government agencies). When you look at these reports, you may notice large gaps in between the dates each report is published, but this is because ProtonVPN rarely receives user data requests.
Overall, ProtonVPN has a transparent no-logs policy, is headquartered in a country with strict data privacy protection laws, and has open-source apps that have been audited and confirmed to be safe.
ProtonVPN Speed & Performance
I conducted speed tests for a server in each of the 60+ countries where ProtonVPN has a server to find the average VPN speed using VPN Accelerator — and my average decrease in speed was 20%, which is above average.
Overall, ProtonVPN had very good speed on local servers (I’m located in the US) as well as distant servers in Europe, South America, and Africa. I maintained really good speeds for browsing, streaming, gaming, and torrenting on nearby servers, and I had a similar experience when I connected to a distant server in Australia (where videos took extra time to load but played smoothly once they started).
I first ran a speed test connected to my local internet service provider (ISP) to get a baseline of my internet speed.
Then, I clicked on ProtonVPN’s Quick Connect tool (that finds the fastest server) and was connected to a nearby server. I had a 27% drop in download speed, but I was able to surf the web, watch videos on YouTube, and share files with no delay. In fact, it felt as if I wasn’t even connected to a VPN.
Next, I connected to a ProtonVPN server in Italy. My ping (the time it takes for the internet signal to travel from the device to the VPN server) significantly increased and my download speed decreased by only 12% (less than my speed loss connected to a server in the US)! Websites loaded almost instantly, content on Netflix and Disney+ streamed in HD quality and without any lag (it took just 2-3 seconds for TV shows and movies to begin), and I still downloaded large files at fast speed.
Finally, I connected to a ProtonVPN server in Australia, which is one of the farthest servers from my location, and I experienced slightly slower browsing speeds (although my download speed actually increased a little bit from what it was in Italy). Websites averaged about 3-4 seconds to load, and it took anywhere from 15-30 seconds for content to start to play on streaming apps, but TV shows and movies remained in HD the entire time and there was no buffering.
Overall, ProtonVPN has some pretty fast speeds to support almost any online activity. I maintained great speeds when I connected to servers in the US (my home country), and ProtonVPN still provided me with sufficient speeds on distant servers to stream content with only minor delays (just for the content to load) and share P2P files.
ProtonVPN Servers & IP Addresses
ProtonVPN has 1,700+ servers located in 60+ countries. Some top VPNs have more servers (CyberGhost VPN has 8100+ servers), and other VPNs have servers in more countries (ExpressVPN is in 94 countries), but I think ProtonVPN’s server network is good enough for most users. While most of ProtonVPN’s servers are located in the US and Europe, it has servers in Central and South America, Africa, Asia, and Australia — so you’ll be able to connect to a nearby server no matter where you live.
I like that ProtonVPN only uses physical servers — these provide better security than virtual servers (which aren’t located in the same country whose IP address you get). ProtonVPN also uses shared IP addresses. This is good because you share the same IP address with many other users, which helps provide extra anonymity. If you’re looking for a dedicated IP address, you need to look elsewhere, as ProtonVPN doesn’t have them — PrivateVPN offers them for free and CyberGhost VPN and Private Internet Access offer them for an additional cost.
I really like ProtonVPN’s Plus servers that are designed for accessing streaming sites. I rarely had a problem streaming content on my favorite sites while I was connected to a Plus server. If you want to torrent, ProtonVPN has dedicated P2P servers located in 16+ countries.
You can use any one of Proton’s 60+ servers as an exit server while enabling Secure Core servers, and ProtonVPN will connect you to the Tor network with one click on its Tor Over VPN servers in the US, France, Germany, Iceland, Sweden, Switzerland, and Hong Kong.
Overall, ProtonVPN has a good network of physical servers, and it has dedicated servers for streaming, torrenting, and connecting to the Tor network.
ProtonVPN Streaming & Torrenting
ProtonVPN claims to work with 30+ different streaming apps. And it includes an easy-to-follow, step-by-step guide on how to access each streaming service. ProtonVPN provides access to streaming content only on its Plus servers, which are only available to ProtonVPN’s premium Plus subscribers. ProtonVPN says that it’s able to access sites like Netflix, BBC iPlayer, Disney+, HBO, Hulu, Amazon Prime, and ABC.
ProtonVPN allows torrenting on its dedicated P2P servers. These P2P servers are located in 16+ different countries, including Iceland, Singapore, Switzerland, and the US. I downloaded files using BitTorrent and uTorrent, and ProtonVPN worked seamlessly with each torrent client. Before I began to download any files, I first ran a handful of DNS leak tests on 10 different servers. I wanted to make sure ProtonVPN wasn’t going to leak my IP address or any other personal information while I was torrenting. Fortunately, none of my tests revealed any leaks.
Overall, ProtonVPN is good for accessing streaming content, and it also supports P2P traffic. I was able to access popular streaming sites like Netflix, HBO, and Amazon Prime, as well as download content on all major torrenting clients.
ProtonVPN Bypassing Censorship
ProtonVPN is not the best option for overcoming internet censorship in countries that restrict online access.
It doesn’t have certain obfuscation tools that help bypass internet blocks in countries like China. But there have been limited reports of ProtonVPN overcoming restrictions in countries that are less able to detect VPN traffic.
That said, if you live in a restrictive country, I recommend ExpressVPN, which provides obfuscation on all of its 3,000+ servers.
ProtonVPN Plans & Pricing
ProtonVPN has a free plan as well as several paid plans that come with the same features and only differ in the subscription length.
ProtonVPN Free allows for 1 device, has “medium” speeds, and provides access to just 3 servers (in the US, Japan, and the Netherlands). I really like how the free plan gives you unlimited data (unlike other free plans that place a limit on data), but you don’t have access to Plus servers for streaming, dedicated torrenting servers, or the NetShield. That said, ProtonVPN’s free plan is still the best free VPN on the market.
ProtonVPN’s Plus plan allows 10 simultaneous connections, access to all 1,700+ servers in 60+ countries, includes the “highest” speeds, and also adds access to the Plus servers for streaming, dedicated torrenting servers, Secure Core servers, Tor servers, and NetShield. Starting at 4,99 $ / lună,the Plus plan is available for a 1-month, 1-year, and 2-year subscription.
All ProtonVPN premium plans are backed by a 30-day money-back guarantee, but I don’t like that ProtonVPN’s money-back guarantee is prorated. This means that you are charged for each day that you use ProtonVPN up until the 30-day deadline. So, if you cancel ProtonVPN after using it for 15 days, you will only receive a 50% refund — not a 100% refund like most every other competitor offers (like ExpressVPN and Private Internet Access).
ProtonVPN accepts credit cards, Paypal, Bitcoin, and cash.
Overall, there are much cheaper VPN options than ProtonVPN on the market — for example CyberGhost VPN includes similar features, faster speeds, a 45-day 100% money-back guarantee, and is much cheaper. But if you’re looking for a VPN that places a heavy emphasis on security and privacy, ProtonVPN is a very good value.
ProtonVPN Ease of Use: Mobile & Desktop Apps
ProtonVPN offers apps for Android, iOS, Windows, macOS, Linux, Chromebook, and Android TVs. It also works on some routers. Downloading and installing ProtonVPN is very easy — I added ProtonVPN onto my Android and iOS smartphones in about 1 minute, and it took less than 5 minutes to install the app on my Windows and Mac computers.
ProtonVPN’s Android app is really good — it’s feature-rich, provides fast speeds, and is very easy to navigate.
I really like how easy and quick it is to find a fast ProtonVPN server. You can use the Quick Connect option (which automatically connects you to the fastest server) or manually choose a server — ProtonVPN indicates each server load percentage with either a green dot (low percentage), yellow dot (medium), or red dot (high). It’s easy to find P2P, Plus, and Tor servers by tapping on the drop-down button that lists all of the servers for each country.
You can also connect to a server using a map, but I don’t recommend this option for Android or iOS — it will take you extra time to find your desired connection point because you will need to zoom in on popular server locations (like Europe).
I really like the app’s “Profiles” option on the main screen. This is where you can create your own connection preferences — you can choose the country you want to connect to, automatically pick the “fastest” server or manually select a specific server, and enable Secure Core and Smart Protocol (which automatically switches you to a different protocol if the default protocol is blocked by a network such as an employer or university).
The kill switch isn’t supported within the ProtonVPN app for Android. Instead, you can enable the kill switch by tapping on the “Block connections without a VPN” option on your Android device (ProtonVPN gives you step-by-step instructions on how to do it in the Settings tab). Android also has an “Always-on” feature, which automatically reconnects you to the VPN if you get disconnected (this option is permanently enabled on iOS, but Android users need to manually turn it on).
Overall, I really like ProtonVPN’s Android app — it’s very easy to use, has excellent security features, and is easy to customize.
The ProtonVPN iOS app is nearly identical to the Android app. The biggest difference is the iOS app doesn’t have split-tunneling. However, most VPNs that have split-tunneling don’t support it on iOS and macOS (except ExpressVPN has split-tunneling for macOS versions 10.15 or under and Private Internet Access has split tunneling for all macOS versions). As I noted above, the iOS app doesn’t have a kill switch, but the Always-on tool is permanently turned on with iOS devices.
ProtonVPN’s iOS app is as good as the Android app — it’s well-designed, user-friendly, and includes great security features.
Like the Android and iOS apps, the Windows/Mac apps are very similar to one another.
You can connect to a ProtonVPN server with just one click by using the Quick Connect tool. When you connect to a server, it’s neat how ProtonVPN displays the steps your connection is taking as it’s happening — initializing a connection, authenticating the user, establishing VPN tunnel, and assigning you an IP. At the top of the window, ProtonVPN displays the name of your server (for example, United States > US-NJ#11), your IP address, the load percentage, and your protocol. At the bottom of the screen, ProtonVPN displays “Session Traffic” metrics to highlight your network usage and time.
To manually connect to a server, scroll down the list of countries under the Countries tab (or you can select a country on the map). Like with the mobile apps, ProtonVPN lists the cities where each server is located and the load percentage is indicated by a green, yellow, or red circle. I appreciate how ProtonVPN keeps it simple to find special servers — the P2P servers are identified by arrows on top of one another pointed in opposite directions, and Tor servers have an onion icon next to them.
While the Windows and Mac apps include most of the same features, there are a couple of small differences. The Windows app only comes with OpenVPN and WireGuard, and the Mac app doesn’t have split-tunneling.
Overall, the Windows and Mac apps are full-featured, come with a lot of great customization tools, and are very user-friendly.
ProtonVPN Apps: Is ProtonVPN Easy to Use?
Yes, ProtonVPN’s apps are really easy to use. The Android, iOS, Windows, and Mac apps are built with similar interfaces and include most of the same features. The kill switch isn’t available with the Android or iOS apps. Instead, you must manually activate the kill switch on your Android device, but ProtonVPN provides simple instructions in the Settings tab on how to do this. The iOS app has the Always-on feature that automatically reconnects you to a ProtonVPN server if you get disconnected. Also, the iOS and macOS apps don’t come with split-tunneling, and the Windows app only has OpenVPN and WireGuard protocols — the other operating systems also support IKEv2.
ProtonVPN Customer Support
ProtonVPN provides a thorough library of support guides and a support form, but there is no 24/7 live chat or a telephone contact number.
The support guides offer a good source of helpful information. They are separated into 6 different categories — Account, Download and setup, General Information, Access Content, Troubleshooting, and Speed and bandwidth. The guides are very thorough and answered most of my questions, and when I couldn’t find an answer under one of the categories, the search option provided me with a quick way to find a solution.
ProtonVPN’s support form (which doubles as an email) is so-so. It took me over a day to receive a reply (most VPNs will respond in less than a day), but at least ProtonVPN made a genuine effort to answer all of my questions with detailed information.
However, I really want a live chat option. I like being able to contact an agent and work with them in real time to resolve my problem (competitors like ExpressVPN offer a live chat).
I contacted ProtonVPN via email to request my refund. It was hassle-free, and the money was added back onto my credit card in 5 days.
ProtonVPN’s customer support is not the best, but it’s decent. Not having 24/7 live chat is a big drawback, and I don’t like having to wait to get a response via email. That said, the email response I received was very helpful, and I think the support guides do a good job of answering the most important questions.
Is ProtonVPN the Best VPN for Security and Privacy?
ProtonVPN is one of the best VPNS on the market. It provides great security features, is very easy to use, has really good speeds, works with top streaming services like Netflix, BBC iPlayer, and Hulu, supports P2P file sharing on dedicated servers, and allows up to 10 connections.
When it comes to security and privacy, it’s difficult to top ProtonVPN. It has standard security features like 256-bit AES encryption, a kill switch, and fast and secure protocols, but ProtonVPN also includes extras like Secure Core (double VPN routing), NetShield (ad/tracking blocker), Tor over VPN, VPN Accelerator, perfect forward secrecy, full-disk encryption, and open-source apps that have been independently audited. And ProtonVPN has a strict no-logs policy and is based in privacy-friendly Switzerland, which doesn’t have mandatory data-retention laws and is located outside the 5/9/14 Eyes Alliances.
In my speed tests, ProtonVPN was fast and provided really good connection speeds for browsing, streaming, torrenting, and gaming. Even in distant locations, I was able to watch content in HD and without any interruptions — and websites took only 1-2 extra seconds to load.
But ProtonVPN isn’t perfect. I’m disappointed that ProtonVPN can’t bypass internet restrictions in countries like China, and I’d also like to see 24/7 live chat added to its customer support and a quicker response time with emails (ExpressVPN can be used in China and has 24/7 live chat).
All that said, ProtonVPN has the best free VPN plan out there, and all of its paid plans are backed by a prorated 30-day money-back guarantee.
ProtonVPN — Frequently Asked Questions
Is ProtonVPN safe?
Yes, ProtonVPN is very safe.
In fact, it’s one of the most secure VPNs on the market. In addition to industry-standard security features like 256-bit AES encryption, a kill switch, and a strict no-logs policy, ProtonVPN includes extra features like Secure Core servers (double VPN routing), NetShield (an ad/tracking blocker), perfect forward secrecy (changes your encryption key after each session), and much more.
Is ProtonVPN free?
The free plan allows you to connect 1 device, offers “medium” speeds, and gives you access to 3 servers (located in the Netherlands, Japan, and the US). The best part about ProtonVPN’s free plan is that it doesn’t set a limit on your data. However, if you want access to streaming servers, torrenting servers, Tor over VPN, faster speed, and more connection locations, you’ll need to upgrade to one of ProtonVPN’s paid plans (which are all backed by a prorated 30-day money-back guarantee).
Does ProtonVPN work with Netflix?
Yes, ProtonVPN works with Netflix.
ProtonVPN is pretty fast, so I was able to watch Netflix content in HD quality and without interruptions. But it’s important to note that ProtonVPN only supports streaming on its premium plans — Netflix won’t work on the free servers.
Does ProtonVPN work on Android + iOS?
Yes, in fact, ProtonVPN has some of the best mobile VPN apps.
They both have an intuitive interface, 1-2 tap connections, fast speeds, and include WireGuard, OpenVPN, and IKEv2 protocols.
The only drawback with the iOS app is it doesn’t have split-tunneling (most iOS VPNs don’t). Also, the iOS app doesn’t have a kill switch. Instead, ProtonVPN’s iOS app has a setting that automatically reestablishes your connection if you’re disconnected from VPN.
