Many internet users turn to Virtual Private Networks (VPNs) as a means of protecting their online privacy. A VPN encrypts internet traffic and hides a user’s IP address, making it significantly harder for third parties to track online activities. However, while VPNs offer substantial protection, they do not make a user completely invisible. There are still several ways in which tracking can occur, from browser fingerprinting to government surveillance. Understanding these risks is essential for those who want to maximize their privacy online.
How a VPN Works?
A VPN functions by creating a secure, encrypted connection between a user’s device and a remote server operated by the VPN provider. When connected to the VPN, all internet traffic is routed through this server, masking the real IP address with the VPN’s IP. This process prevents websites, advertisers, and internet service providers from directly associating online activities with the actual user.
By using strong encryption protocols, a VPN ensures that data transmitted between the device and the internet remains secure from prying eyes. This means that even if an internet service provider attempts to monitor traffic, they will only see encrypted information rather than specific browsing behaviour. Websites will also detect the VPN server’s IP instead of the user’s actual IP address, preventing them from pinpointing a real-world location.
However, while VPNs provide an effective way to enhance privacy, they do not eliminate all tracking risks. Other methods exist that can still be used to monitor online behaviour, even when a VPN is in use.
How Tracking Can Still Occur with a VPN?
One of the most common ways users can still be tracked while using a VPN is through IP leaks. A VPN should prevent a website from seeing a real IP address, but sometimes, due to misconfigurations or weaknesses in certain VPN services, the real IP can still be exposed. This happens through DNS leaks, where a device continues to use the ISP’s DNS servers instead of the VPN’s, allowing tracking of browsing habits. If a VPN connection drops unexpectedly and does not have a built-in kill switch, internet traffic may revert to the user’s normal connection, exposing their real IP address.
Cookies provide another avenue for tracking, even when a VPN is active. Websites store small files on devices to remember login details, preferences, and past interactions. If cookies are already saved on a browser before connecting to a VPN, websites can still recognize and track the user, even if their IP address has changed. This is especially true for third-party tracking cookies, which allow advertisers to follow users across different sites. Unless cookies are manually cleared, they can continue to link browsing activity to a single user, despite VPN usage.
Another advanced tracking technique is browser fingerprinting. Even without an IP address, websites can analyse a user’s browser type, operating system, installed plugins, screen resolution, and various other characteristics. This combination of factors creates a unique digital fingerprint that can be used to track a user across different websites, even when their IP changes. VPNs do not prevent browser fingerprinting, making it a serious privacy concern. Using privacy-focused browsers and extensions designed to randomize or limit fingerprinting can help mitigate this risk.
Malware and spyware also present significant risks. If a device has been infected with malicious software, it can collect and send personal data regardless of whether a VPN is being used. Keyloggers can record keystrokes, while spyware can capture browsing history and login credentials. A VPN does not protect against malware; only strong cybersecurity practices, such as regularly updating software and using reputable antivirus programs, can prevent infections.
Can Governments and ISPs Track VPN Users?
Governments and ISPs have varying levels of capability when it comes to tracking VPN users. In countries with heavy internet surveillance, deep packet inspection (DPI) is often used to identify encrypted VPN traffic. While DPI does not necessarily reveal browsing activity, it can flag VPN usage, leading to restricted access or targeted monitoring. Some governments block known VPN servers altogether, preventing users from bypassing censorship.
ISPs cannot see the specific websites a user visits when they are connected to a VPN, but they can detect that a VPN is in use. They can monitor the amount of data being transmitted and identify connections to known VPN servers. In some cases, ISPs may throttle or slow down VPN traffic to discourage usage. VPNs with obfuscation technology can disguise VPN traffic as regular HTTPS traffic, making it harder for ISPs and governments to detect and block connections.
Can Google and Social Media Track Users on a VPN?
Even when using a VPN, tech giants like Google and Facebook can still track users if they remain logged into their accounts. These platforms do not rely solely on IP addresses to track activity. Instead, they use login sessions, cookies, and device information to build detailed profiles of users. If someone logs into their Google account while using a VPN, Google will still recognize them and associate their browsing history with their account.
To avoid this type of tracking, users should log out of accounts when browsing privately or use separate browsers for personal and anonymous browsing. Search engines that do not track users, such as DuckDuckGo, offer an alternative to Google for those seeking greater privacy.
How to Maximize Privacy While Using a VPN?
To enhance privacy and reduce tracking risks, users should combine VPN use with additional security measures. Choosing a VPN provider with a strict no-logs policy ensures that online activity is not stored or shared with third parties. Enabling a VPN’s kill switch feature prevents data leaks if the connection drops, maintaining privacy at all times.
TuxlerVPN is an option that provides an extra layer of anonymity by offering a residential VPN service. Unlike traditional VPNs that route traffic through data centre servers, tuxlerVPN allows users to connect through real residential IP addresses, making it harder for websites and advertisers to detect VPN usage. This can be especially useful for bypassing geo-restrictions and avoiding VPN blacklists that some streaming platforms and online services enforce.
Using a browser that prioritizes privacy, such as Brave or Tor, can help minimize tracking from cookies and fingerprinting. Regularly clearing cookies and browsing history further reduces the risk of websites recognizing returning users.
Disabling JavaScript and blocking third-party trackers through browser extensions can provide additional protection. However, some websites rely on JavaScript to function properly, so users may need to find a balance between privacy and usability.
Keeping software up to date is crucial, as outdated programs often contain security vulnerabilities that can be exploited for tracking or hacking. Ensuring that a device has strong antivirus protection adds another layer of defence against malware.
When browsing sensitive content, using anonymous email accounts and avoiding logging into personal accounts can help prevent activity from being linked back to an individual.
Conclusion
While VPNs significantly improve online privacy, they do not make users completely anonymous. Tracking methods such as IP leaks, browser fingerprinting, cookies, and government surveillance can still reveal user information, even when a VPN is active.
By understanding these risks and taking additional security measures, users can minimize their exposure to tracking. A VPN is a valuable tool for privacy, but it should be used alongside other privacy-enhancing practices to ensure maximum protection. Maintaining strong cybersecurity habits, using privacy-focused software, and staying informed about new tracking techniques are all essential for those who want to stay anonymous online.
