Reviewing a VPN may be difficult. There’s lots to think about, an array of things and options to weigh up, and everybody has their very own view on what’s essential, and what actually is not.
On this function we’ll clarify the important thing points we contemplate, how we go about evaluating and testing them, and the way we in the end determine {that a} service like ExpressVPN comes out on prime.
And it is price noting that what we have laid out right here could also be only a fraction of what would possibly doubtlessly occur in our precise evaluations. If we’re interested in precisely what a VPN app is doing – possibly we’re questioning if it could be malicious, for example – we would run its executable previous a safety scanner, look at the code of a browser extension or decompile and browse a .NET shopper. However then, going into that kind of element would require a whole e-book to cowl correctly!
In fundamental phrases, we do the geeky stuff in order that you do not have to. However to grasp extra deeply how we consider and take a look at VPNs, simply maintain studying.

The very best total VPN we have examined
When you think about the factors we have laid out for our testing beneath, there aren’t many VPNs that appear to tick each single field – however ExpressVPN is one which does. We find yourself straining sinews to think about actual ‘cons’ for Categorical – it has fast connections, a great deal of servers around the globe, is a gem to make use of throughout a complete vary of gadgets, surpasses the hardiest of geo-restrictions, has nice 24/7 buyer assist and you’ll strive all of it 100% danger free with the agency’s no quibble 30-day a refund assure.

Definitive verdicts are onerous to search out. It would not matter how typically or how rigorously anybody measures connection speeds from the UK to Germany on a Home windows laptop computer – this may not inform you very a lot in case you’re curious about connecting from Australia to New York in your Android cell.
What we will do is take a look at a variety of completely different facets of the service, and inform you extra about them. You will not be curious about all of those – maybe you solely ever use the identical location, for example, so could not care much less about how the server listing is organized, or whether or not there is a favorites system – however hopefully we’ll cowl sufficient floor to offer you a really feel for what a supplier is like.
Amassing options
The method of evaluating a VPN begins at its web site, by accumulating particulars on the service and its options.
Community dimension issues, although not as a lot as suppliers typically declare (so long as a VPN has the places you want, it would not matter whether or not there are 20 or 2,000 extra). In addition to the numbers, we test to see how broadly dispersed the places are, whether or not they embrace nations you will not all the time get with the competitors, or in the event that they go away gaps in protection elsewhere.
It is equally essential to grasp the providers supported by every server. Do all of them assist P2P, streaming, WireGuard, OpenVPN, and every part else provided by the supplier? This is not all the time straightforward to search out out, however it’s price making the trouble (that listing of 300 places could look a lot much less spectacular in case you notice you’ll be able to solely use P2P with three of them).
An excellent VPN ought to supply customized desktop and cell VPN apps, as they will be the best means to make use of the service. Watch out whenever you’re checking this on an internet site, although. Suppliers typically show an extended listing of platforms, however though a few of these will result in downloads, others would possibly simply level you to a tutorial explaining how one can arrange the service manually. Comply with every hyperlink to search out out for positive.
Figuring out supported VPN protocols tells you a large number in regards to the service. If it covers the important thing requirements – WireGuard, OpenVPN, L2TP/IPSec, IKEv2 – there is a good likelihood you can apply it to most gadgets and platforms (routers, recreation consoles and so forth), even when they are not instantly supported by supplier apps.
(opens in new tab)
We pay shut consideration to any particulars of how every protocol is carried out, too, together with the specifics of any encryption and authentication strategies which could be employed. These aren’t all the time seen upfront, however there’s often info tucked away within the assist web site.
Does the VPN have any attention-grabbing bonus options? Frequent examples are advert, tracker and malicious URL blocking; the supplier’s personal DNS system; VPN over Tor; break up tunneling, permitting you to decide on which functions use the VPN, and which do not; and possibly Bitcoin assist for funds, enhancing your anonymity whenever you join.
Testing the worth helps us to grasp whether or not the service is sweet worth, however there’s extra to that than taking a look at a single headline determine. Some apparently low-cost VPNs do not supply their lowest value until you join a number of years, so it is essential to have a look at the vary of plans and costs on supply.
If accumulating all this knowledge sounds prefer it might be a prolonged and tedious course of, you are proper; it’s certainly. However it’s not nearly discovering figures and have lists. Simply the expertise of in search of the related info gives you an excellent really feel for what a VPN is like.
A doubtful supplier could be quick on element, for example, with a poorly organized web site making it onerous to search out what you want. Info could be inconsistent or outdated, and you will typically see a bit of advertising trickery, similar to unrealistic pace or web site unblocking guarantees which you watched the corporate cannot ship.
However an expert supplier can have a well-designed web site which makes all crucial info seen upfront, with loads of technical element tucked away in order for you it. Overselling can be stored to a minimal, and honesty and transparency is prone to be the order of the day.
Privateness
Assessing the extent of privateness provided by any VPN is tough, as you are counting on the supplier to truthfully inform you what they’re doing and the way the service works. Nonetheless, there’s typically sufficient info to level you in the fitting course.
This begins with the technical knowledge you collected earlier on the protocols supported, the encryption and authentication. WireGuard and OpenVPN assist is greatest, IKEv2 not far behind, L2TP/IPSec is suitable, however the outdated and insecure PPTP is greatest averted solely.
We’d search for AES-256 knowledge encryption, RSA-2048 or 4096 to cowl handshaking, and Excellent Ahead Secrecy to generate new keys for every session – however the reality is that VPNs do not all the time absolutely spell out what they’re doing. Whereas some go above and past the decision of responsibility, like the way in which that NordVPN affords further safety smarts like Double VPN and Onion assist.
It is typically essential to browse the assist web site for clues, or you’ll be able to obtain pattern OpenVPN configuration recordsdata to offer you an thought of how the service works. If the service has stay chat, strive it out; the brokers can often reply pre-sales queries, so that you should not have to enroll to get recommendation.
App options are key. High quality VPNs will use their very own DNS servers and implement DNS leak safety (IPv4 and IPv6) to scale back the prospect of your web actions changing into seen to others. You will additionally need to have a kill swap to routinely block web entry if the VPN connection drops.
(opens in new tab)
Beware: simply because a service has ‘kill swap’ on an internet site function listing doesn’t suggest that this functionality can be out there on each platform. Cell apps typically have fewer options and features than their desktop siblings, for example, so we test each to totally perceive what it does.
To verify {that a} VPN is correctly hiding your IP deal with, connect with any VPN location and level your browser at ipleak.web. When you see your actual IP deal with, or an deal with owned by your ISP, there’s an issue which you might want to examine additional. Outcomes can range in response to browser setup, so repeat this in each browser and on each machine you employ.
We assess kill switches on Home windows VPN shoppers by utilizing numerous low-level tips to forcibly shut our VPN connection, then monitor how lengthy the web stays accessible, and whether or not our common exterior IP is seen to the skin world.
It is a technical enterprise, however our How one can take a look at your VPN kill swap information has easy checks you may make your self.
At a minimal, simply flip off your router and watch your app. Does it recognise it is disconnected, does it warn you, does it reconnect when the router is again? An excellent VPN app handles sudden occasions like this and retains you knowledgeable; a foul app may not even realise you are now offline.
Logging
VPN suppliers, notably free providers, are recurrently accused of promoting their customers searching historical past. Most will attempt to struggle again, sometimes by yelling ‘No logging!’ on the entrance web page of their web site, however years of assessment expertise has instructed us this is not all the time true. That is why we all the time look a bit of deeper.
The privateness coverage can inform you a large number a couple of supplier, even earlier than you learn it. 5,000 phrases of poorly-formatted, jargon-packed legalese is a foul signal, and so is a 100-word doc which tells you virtually nothing. What we’re in search of is a clearly formatted, well-organized and readable doc which permits anybody to search out the important thing particulars they want.
These particulars ought to be specific and canopy all logging potentialities. A single line saying, ‘we by no means beneath any circumstances log what you are doing on-line’, for example, would not rule out the chance that the service would possibly document session knowledge: the date and time you log in, your incoming IP deal with, the VPN IP deal with you are assigned, the date and time you disconnect and the bandwidth you employ. That degree of element might be sufficient to permit others to hyperlink an web motion to your account.
A greater coverage will rule out this chance by explaining that it would not log join or disconnect occasions, incoming and outgoing IP addresses, and so forth.
The very best insurance policies may even inform you what they do document, why they achieve this, and what occurs to that knowledge. For instance, a supplier would possibly say that it logs the final connection time and the bandwidth utilized in that session, however would not document incoming or outgoing IP addresses. It may clarify that this knowledge is helpful to assist the corporate monitor service use and establish inactive accounts (is smart), however would not enable anybody to search out out what you are doing on-line (fairly true). And it would inform you that in case you not use the service, you’ll be able to e mail assist and so they’ll delete your outdated account knowledge solely.
It is essential to maintain this in perspective. Nonetheless well-presented a privateness coverage could be, there is no assure that something stated within the doc is definitely true. It is all primarily based on belief.
Testing the small print can spotlight logging {that a} VPN is admitting takes place, although. And if nothing else, it can provide you clues about how sincere and open a supplier could be.
We have beforehand discovered doubtful free VPNs who’ve copied and pasted another person’s privateness coverage, modified any firm names within the textual content and pretended it is theirs, for example. That is lazy, incompetent, and fraudulent, actually – greater than sufficient to inform you that this is not a supplier it is best to use.
Safety audits
VPN suppliers know there is a lack of belief within the enterprise, however many are attempting to counter this by placing themselves by way of impartial safety audits.
The concept is {that a} supplier invitations an skilled staff to look in-depth at safety or privateness points with its methods, and report again with their findings.
Any VPN which places itself by way of this course of deserves actual credit score for having the braveness to show its inside workings to the world. However not all audits are the identical, and their true worth relies on a variety of things.
What’s the scope of the audit, for example – what did the auditors strive to have a look at? If it is a tiny facet of the service, just like the browser extensions, that is not going to imply very a lot. Inspecting the complete vary of apps is extra helpful, and the most effective audits will go even additional. TunnelBear’s safety audit contains its infrastructure and even the web site, whereas NordVPN now calls in PricewaterhouseCoopers to finish an impartial assessment of its no-logs coverage.
Try what the audit was designed to do, too. Generally audits merely test that, say, the service follows the no-logging guidelines within the privateness coverage. That is good, however others go additional, maybe placing apps by way of in-depth testing to establish bugs and privateness flaws.
What degree of entry did the auditors must the service? With the ability to take a look at an app is sweet, however accessing the supply code, and actual VPN servers, is way, significantly better.
Is the ultimate report out there, in full, to the general public? Ideally anybody ought to have the ability to take a look at it. Some experiences are solely out there to paying clients – not so handy, however we will stay with that. A number of aren’t publicly out there in any respect, although, which leaves you having to belief the VPN’s personal abstract of the decision. (Ironic, contemplating audits are purported to be about decreasing this want for belief.)
Lastly, how way back did the audit happen? A top quality VPN is all the time extending and enhancing its methods, so a report from two years in the past will not have almost as a lot worth at the moment. We search for suppliers that not solely put all their providers up for inspection, however companies that decide to do it subsequent 12 months, too.
Efficiency
We measure VPN efficiency utilizing Home windows 10 methods in two places: a US house, and a Home windows 365 cloud PC hosted within the UK.
Every makes use of wired Ethernet, avoiding Wi-Fi points, to entry a 1Gbps web connection. That is a lot quicker than most gadgets and houses, however offers us the area to see precisely what every service can do.
A take a look at session begins by checking our regular web speeds (that is with the VPN off.) We use not less than three pace take a look at websites or providers, from a range together with SpeedTest’s web site and command line app, SpeedOf.me, nPerf and Netflix’s Quick.com. We run not less than 5 assessments at every web site, and take the median worth as our common.
Subsequent, we use the VPN app to connect with its nearest server utilizing the most effective out there protocol (WireGuard, OpenVPN or a customized protocol of its personal). After that, we go to the identical pace take a look at websites we used earlier, once more working not less than 5 checks, and calculating our new median speeds.
VPN apps typically assist a number of protocols, and we won’t be utterly positive which can ship the most effective speeds. So after measuring an app’s WireGuard speeds, say, we’ll disconnect the VPN, reconnect utilizing OpenVPN and run all of the assessments once more.
This takes some time and entails many assessments (an absolute minimal of 45), however we’re not completed but. We run all these assessments in each morning and night periods, simply in case our first checks are affected by short-term community, take a look at atmosphere or different points.
Whereas we’re attempting to get a consultant thought of VPN efficiency, there is a restrict to what these outcomes can inform us. They’re giving us a snapshot thought of how the VPN performs from our take a look at places within the US and UK, however in case you’re elsewhere on the earth, connecting to a different server, and 6 months later, chances are you’ll properly see completely different outcomes.
Unblocking
Many VPNs boast that they’re the most effective streaming VPN – claiming they may also help you get round geographically-based blocking and allow entry to content material which you may not in any other case have the ability to see. Sounds good, however is it true? To evaluate this, we begin by trying on the claims the supplier makes.
An excellent supplier will state clearly which providers it claims to make accessible (Netflix, Hulu, and so forth), and possibly which it will probably’t. The assist web site would possibly embrace articles which clarify what you are able to do if a web site stays blocked, and invite you to contact the assist staff instantly in case you need assistance. If you cannot entry Netflix through ExpressVPN, for example, you are capable of open a stay chat session with the assist staff, ask them which server to make use of, and get a advice inside a few minutes.
Lesser VPNs may not have any troubleshooting articles, and so they’ll be much less prone to decide to serving to you entry any specific web site. As a substitute of claiming ‘in case you’re blocked, contact us for assist’, they will give extra of an impression that ‘in case you’re blocked, powerful, we won’t promise something, that is simply the way in which it’s’.
Essentially the most doubtful VPNs will appear to be they’re making large guarantees, maybe claiming they ‘assist you to entry ANY web site’, or displaying Netflix and different logos to suggest that they will be out there, with out particularly saying that. However dig deeper and you will both discover no background info in any respect, or only a disclaimer saying they can not assure something.
To check this ourselves, we try to entry and stream unique regional Netflix titles from a lot of servers worldwide, Amazon Prime Video and Disney+ content material from a number of US VPN servers, and BBC iPlayer from all out there UK servers. The outcomes are logged, and in the event that they’re solely adverse and the supplier suggests they should not be (the corporate claims we will entry Netflix, and our checks say in any other case), and recommends asking for assist, we get in contact with the VPN’s assist staff to see what they’ll supply.
Even at this late stage, how a company responds may be essential. If the supplier can suggest one other working server, inform us that it is conscious there’s a difficulty and that it’s taking motion, the agency will earn bonus factors. If not, and if the corporate would not stay as much as guarantees made on the web site, then it is going to be penalized.
Apps
A VPN can have an unlimited community of quick and dependable servers, however that is not a lot assist if its apps make the service tough to entry or use. That is why we place a variety of significance on a supplier’s software program, its options and usefulness.
We count on a service to supply its personal Android VPN apps and others for Home windows, Mac and iOS. Assist for added platforms is not as essential, however does give us helpful details about the supplier. The vast majority of customers will not care if their VPN has a Linux shopper, for example, however its existence alone tells us the supplier has sources, actual VPN expertise, and is doing its greatest to achieve and assist the utmost potential viewers.
Some providers additionally supply browser extensions. These are extra restricted than apps, as most solely shield browser visitors, and never different applications working in your machine. However there are exceptions: ExpressVPN’s Chrome VPN extension can talk with and management the native ExpressVPN shopper on a PC.
App usability is essential. It is also very subjective, however we attempt to take crucial elements into consideration.
The opening interface ought to make it straightforward to search out the server you want, or reconnect to generally used places. A easy alphabetically sorted listing, with a search field and a favorites system, may do the trick. Apps the place places are sorted in an apparently random order, or which drive you to make a number of clicks to get related, usually get marked down.
It is vital {that a} person is aware of when the VPN is defending them, so the app ought to show notifications to point out when it is connecting, related, or when the connection drops. Not everybody needs this degree of interplay, although, so the perfect apps may even provide the choice to customise the notifications you see.
Many apps embrace an ‘automated’ or ‘quickest’ choice mode, the place in concept they select the most effective server for you. This does not all the time work as we count on, although (regardless of testing from the UK, one VPN determined our quickest server was in India), so we test this rigorously to substantiate the outcomes make sense.
We have already described how we measure peak obtain speeds, however they are not the one measure of how a VPN performs. That is why we would additionally test connection occasions, benchmark DNS queries, browse web sites, take a look at video streaming efficiency, and customarily consider the real-world expertise of utilizing every VPN.
Settings matter, too. On desktops particularly, we need to see a kill swap, making certain web entry can be blocked if the connection drops. An app which may routinely join whenever you entry new networks is effective, as you will not have to recollect to do it your self. The very best apps add further configuration touches, similar to all the time connecting whenever you entry a identified untrusted Wi-Fi community (an area espresso store), however not stepping in with networks you understand are secure (house, work.)
Extra geeky touches, similar to the flexibility to launch customized scripts whenever you join or disconnect, are welcome, and may be vastly highly effective. However we do not place an excessive amount of weight on these in scoring phrases, because the overwhelming majority of customers won’t ever pay them any consideration in any respect.
Assist
VPNs can run into all types of hard-to-diagnose points, and it is essential that each supplier affords quick, correct and dependable assist.
The web site ought to embrace loads of useful setup, utilization and troubleshooting guides. The set up part wants tutorials for a number of platforms, for example, and will cowl as many working system variations as potential. A generic Home windows setup information is okay, for example, however the interface has modified over time, so separate guides for Home windows 7, 8 and 10/11 is healthier.
Troubleshooting recommendation ought to be thorough, and display real experience. We’d search any net knowledgebase utilizing frequent key phrases, similar to ‘pace’, then browse the outcomes. Poor suppliers may not give any helpful hits. A greater service will return articles on matters like enhancing efficiency, although with solely fundamental info which accommodates nothing you could not work out already (‘connect with a better server’, ‘strive once more later’).
However the most effective suppliers will broaden each thought to offer you greater than you anticipated (‘this is how one can use the shopper’s displayed ping occasions to discover a nearer server’), and go away even essentially the most skilled customers with a greater understanding of the issue than that they had earlier than.
An online knowledgebase can by no means inform you every part you might want to know, so it is essential that you just’re capable of get actual, stay, human assist. Ideally this ought to be out there 24/7, with stay chat as an possibility, however do not rule out e mail or ticket assist. This has its benefits – you are capable of suppose extra about what you say earlier than you say it, and fasten logs or screenshots to assist clarify the scenario – and the most effective suppliers reply to questions in beneath an hour.
We check out the stay chat or e mail assist of every VPN supplier with not less than one pattern query, simply to get a really feel for the way it performs. As with many different facets of a assessment, this type of one-off snapshot cannot inform us every part we would need to find out about a supplier’s hand-holding talents.
We have discovered it typically offers us attention-grabbing details about the service, although – an ultra-fast response right here, a really unhelpful one there – and all of it helps to construct a extra detailed and correct image of how good (or in any other case) a VPN could be.
