What Does Leak Mean In A VPN

How to Check Whether Your VPN is Working and Secure

A VPN is designed to cloak your IP address and also provide a safe tunnel through which your data gets transported. The data is also encrypted via a variety of protocols, depending on what VPN provider you choose to use.

If any of your information is made available, your IP address, your data or online activity that is known as a leak. Your private information should be kept private and if not then that is considered a leak. Logging on and logging off are two points where leaks are prevalent. For that reason, your VPN should use kill switches and other methods to protect your activity.

VPN Server Detection: Is It Possible & How To Avoid It

Some websites and services that have geoblocked content dont really like when their users connect via VPNs Netflix being a perfect example. Services like this tend to keep a repository of IP addresses they know come from VPN providers, and if they notice that youre connecting from one of them, they might prevent access.

The solution is to find a VPN provider that changes your public IP address often enough so that it doesnt get listed in one of those repositories.

Of course, VPNs have some rather creative ways of working around this. You could opt for a VPN service like NordVPN that offers you a personal public IP address that nobody else can use. Or, you also have Surfsharks obfuscated servers, which disguise your VPN-protected traffic as regular traffic so that servers cant detect youre using a VPN (read more about the VPN in our Surfshark review.

Ip Address Leaks Dont Let Them Know Where You Are

The most common form of VPN vulnerability is an IP address leak, which occurs when an outside website or service is able to detect the true IP address assigned by your ISP even when you are connected to the VPN client.

This allows third-parties to detect your true location and potentially execute a cyberattack.

To start investigating a potential IP address leak, open a web browser before connecting to your VPN and navigate to This site will display the IP address assigned by your ISP.

Then launch your VPN client and reload the webpage to check your new IP address. This is the one that all websites will see while you have an open VPN session.

How a VPN Can Fail at Masking Your IP Address

Due to a service known as Web Real-Time Communication , many VPN clients are at risk of revealing their users local IP address.

WebRTC is used by a lot of popular applications and websites in order to update live content on a webpage, such as a social media site or email inbox.

Because of the way that data is transmitted between your browser and sites that use WebRTC, certain VPN clients fail to disguise the source IP address.

As an initial check, the site has a WebRTC leak test that will show you how your browser is transmitting your IP address. If the test can detect the IP address assigned by your ISP, then it means your VPN or web browser is leaking that information.

    How Dns Leak Tests Work

    A typical DNS leak test involves sending a series of URL requests for your VPN client to resolve, assuming youre connected through your VPN. Put simply, the test is asking your browser to look up a series of different URLs. The requests will be sent to whichever DNS servers your VPN service uses.

    If the IP address thats returned isnt that of a server owned by your VPN provider, it means youre leaking data. If they have one, its best to use a test provided by your VPN company thats because other tools might not know if the DNS youre using is a VPN DNS, and might just assume that anything sent back is the result of a leak.

    Review Your Router Security

    How Secure is your VPN ? How to check the security of your VPN ?

    Every wireless router comes configured with a default username and password, credentials that are necessary any time you want to change important settings. Older routers in particular may come with simple-minded values like admin for both username and password, and you can be sure that all those defaults are known to hackers.

    You may also find that the default username and password appear on a sticker on the bottom or side of your router. Thats safer than using dumb default credentials, but anybody who enters your den or office could snap a pic of those credentials. You might even be giving away those credentials in your video meetings, if your router is visible in the background.

    If you dont know whether your router is using default credentials, check with your internet providers tech support. Once you can log in, change the router password, and record it in your password manager. While youre logged in to the router, check what kind of encryption your Wi-Fi connection is using. WEP and WPA are old, insecure encryption methods not good! You want WPA2 with AES. Chances are good you can simply choose the new encryption method from a drop-down list. One warning some older devices such as Nintendo DS and Sony PSP arent compatible with WPA2.

    VPNs With Webrtc Leak Protection

    Since WebRTC might leak your IP even while your VPN is active, its important to do your homework before you invest in a VPN. Some VPNs offer WebRTC leak protection, which will ensure that your IP address doesnt accidentally leak through WebRTC data. Two great VPNs with WebRTC leak protection are:

    • NordVPN: Both Nords browser extension and their full VPN service help prevent WebRTC leaks.
    • ExpressVPN: Expresss browser extension includes a feature that will block WebRTC functionality once enabled. It also offers its own WebRTC leak test on its website.

    How Do I Check If My VPN Is Working

    The privacy features of a VPN dont guarantee absolute anonymity. Even if your information is hidden from third parties, your VPN provider can still see your information and even retain it. Thats why its always a good idea to run a VPN anonymity test to ensure that your data is kept anonymous, at least from external parties.

    The VPN encryption test is another useful test you can run to ensure that your data is encrypted once it goes through your VPN. Two apps to use for this purpose include Glasswire and Wireshark. Although Wireshark is considered more reliable than Glasswire, installing either one of these apps on a device using the VPN can verify VPN connections and encryption.

    If youre using a firewall in addition to a VPN, you should also run a firewall leak test to ensure there arent any security threats to your device, whether they be VPN or firewall leaks.

    VPNs Are Not All The Same

    Before you rush into installing a VPN on all your teams computers, laptops, and mobile devices, it is highly recommended that you first test your VPN provider for possible problems, including:

    • IP address leaks
    • WebRTC leaks
    • Inconsistent speed

    Below, Ill explain the main vulnerabilities of VPNs, what they can mean for your business, and how to protect against them.

    How Do I Know If My VPN Is Secure

    Is My VPN Working? How To Test for VPN Leaks

    We live in a modern world where privacy is scarce because almost every device or service we use collects our personal information for financial gains. Luckily, we have tools such as VPNs available, which allow us to protect our privacy by hiding our IP Address which is basically your digital address. Now when it comes to VPNs, there are tons of them available, and sadly not all of them are not secure as you think. So, if you are interested in getting a VPN and wondering how I know if my VPN is secure, this guide is for you. In this VPN Guide, we will tell you about the major factors which you can use to determine if a VPN is secure or not. Lets get started.

    How Does A VPN Protect Your Privacy

    VPNs use encryption protocols to protect your data from snoopers. Hiding your location and personal information, they make your connection anonymous and private.

    Every VPN protocol is responsible for defining how app and server connect with each other as well as the methods used to send and encrypt data. There are several types that VPNs use to secure your flow of information into an encrypted tunnel.

    Among them, OpenVPN has historically been the most secure that you can get and many providers offer this protocol. As the name suggests, it’s an open source software meaning that anyone can check if the code is working as it should. Its original design dates back to 2001, but much has changed in the tech world over the last 20 years.

    A relative newcomer into the world of VPN protocols, WireGuard is now among the choices offered by many providers – these include Surfshark and Private Internet Access, while NordVPN uses it as a basis for its own NordLynx protocol. On top of that, our testing shows that its connection can be up to three times faster than OpenVPN.

    Offering a no-logs policy is another effective way to protect your online privacy. It’s the VPN provider’s guarantee that it will not keep any of your personal data in store.

    And is another feature that enhances VPN safety. It tricks the system by assigning the same IP address to multiple users from different locations, basically making it impossible to trace you.

    Is Your VPN Susceptible To Webrtc Leaks

    WebRTC is a technology used by many popular online apps including Google Hangouts, Facebook Messenger and Discord. Using peer-to-peer tunnels, WebRTC allows high-definition video and audio to be sent from one user to another in real time.

    While WebRTC is a highly useful technology for creating web apps, it also poses a security risk for users of VPNs without WebRTC leak protection. Since WebRTC creates a new peer-to-peer connection between users, this connection will bypass the secure VPN tunnel and potentially expose your real IP address.

    Finding out if your VPN is susceptible to this kind of leak is possible using a WebRTC leak test. If you are vulnerable, then you will need to switch off WebRTC from your browser. This will disable apps like Google Hangouts, but will ensure that your online security stays protected.

    There are apps available on Chrome, Firefox and Opera for disabling WebRTC, which you can easily find by searching WebRTC block in each of their respective extension shops. In Safari, WebRTC is usually disabled by default.

    Browser Extension VPN Leak Test

    You can determine whether you have a browser extension leak through several simple steps, especially with a Chrome browser. Its important to note that you need to test the VPN connection from inside the network that you want to be inspected for leaks. Take these steps:

  • Activate the Chrome plugin on the VPN.
  • Go to chrome://net-internals/#dns and click on Clear Host Cache.
  • Go to any website and check which IP address your VPN is displaying.
  • If the IP address your VPN shows is your actual IP address, this indicates an extension leak.

    NOTE: VPNs give you access to blocked content, especially about videos that you cannot stream in your region or country. So, if you want to watch something that has been blocked in your region, consider the quality VPN for streaming.

    How To Fix Webrtc Leaks

    WebRTC is not connected to your VPN, so changing VPN wont help. Browsers like Chrome, Firefox, and Opera usually have WebRTC enabled by default. To fix WebRTC try the following:

    Disable WebRTC by installing a browser that excludes WebRTC. Safari and Internet Explorer dont have WebRTC deployed by default, so you can use one of those browsers to fix WebRTC leaks.

    How To Check Your VPN For Leaks

    An important thing to remember is that not all VPN providers are reliable, and not all VPN applications were created equal. As a result, we advise anybody who uses a VPN to gain better security online to:

    • Make sure they get a VPN service that is trustworthy and reliable
    • Test their VPN connection themselves to ensure that it is not suffering from any leaks

    If a VPN leaks data, it is possible that your privacy and data security is being compromised. As a result, using the VPN software can actually lead to a false sense of security.

    The good news is that anybody can use our online leak test tool to check their VPN for IP leaks, DNS leaks, and WebRTC leaks. As long as the VPN suffers from no leaks, it is working correctly and you can trust the VPN software to provide robust encryption for your data.

    Activity Tracking What You Dont Want

    As mentioned before, the primary responsibility of a VPN endpoint server is to take an incoming web request, decrypt it, and then route it to the appropriate place on the open internet.

    This transaction is meant to be anonymous, but in reality, it all depends on the trustworthiness of the VPN provider you use.

    When you first sign up for a VPN service, the provider collects your name, email address, and potentially other personal information.

    There is nothing to stop them from connecting that data to the activity that they monitor on their endpoint server. Advertisers and other third-parties would be eager to obtain that type of data for a variety of reasons, not all of them legal.

    The best rule to follow is to be wary of any VPN provider offering a completely free service. Those services typically offer poor performance with potential security implications.

    If you are not paying a monthly or yearly fee for your VPN client, there is a good chance your web activity is being tracked or shared without your direct consent.

    However, this is not always the case. Check out our list of the best free VPNs for Aussies to distinguish between them.
