Virtual Private Networks (VPNs) have become an essential tool for protecting your privacy and security online. As more of our lives move onto the internet, there is an increasing risk of having your personal data tracked or compromised. Using a VPN adds a critical layer of protection.

What is a VPN?

A VPN creates an encrypted tunnel between your device and a remote server operated by a VPN service. All of your network traffic is routed through this tunnel, preventing outsiders from accessing or tracking your activity.

When you use the internet without a VPN, your internet service provider (ISP) can monitor all of the websites you visit and services you use. They can then sell this data to advertisers or other third parties. A VPN hides this activity from your ISP, along with hiding your location and device IP address.

How Does a VPN Prevent Tracking?

There are a few key ways that a VPN stops various parties from tracking you online:

  • Blocks ISP Tracking: ISPs can’t see which sites you visit or what data you send/receive.
  • Prevents Location Tracking: Websites and services see the VPN server’s IP address instead of yours, hiding your location.
  • Encrypts Traffic: The VPN tunnel encrypts all network traffic, preventing tracking by hackers, government surveillance, etc.
  • Hides Online Activity: Your browsing history, downloads, messages, etc. stay completely private.

How to Select a Reliable VPN

While any VPN will provide basic tracking prevention, it’s important to choose a trustworthy provider. Key things to look for include:

  • No Logging Policy: Avoid VPNs that record user activity logs.
  • Kill Switch Feature: This stops internet access if the VPN disconnects to prevent data leaks.
  • Strong Encryption: Look for AES 256-bit encryption or better for optimal security.
  • Speed & Reliability: The VPN should provide consistent speeds and connectivity.
  • Independent Audits: Reputable companies publish regular transparency reports and undergo independent audits to validate their privacy standards and policies.

There are a number of VPN service providers out there. You need to check these this before making a selection. ExpressVPN, NordVPN, and Surfshark VPN for Wi-Fi are among the best options available today.

Other VPN Benefits

In addition to blocking online tracking and protecting your privacy, VPNs provide other useful benefits:

  • Access region-restricted content and websites.
  • Secure public Wi-Fi connections from hackers.
  • Bypass internet censorship and access blocked sites.
  • Avoid bandwidth throttling by your ISP.
  • Enhanced security for remote workers.

Can You Still Be Tracked With a VPN?

While VPNs provide excellent protection, there are some limits to what they can prevent:

  • Websites may still use tracking cookies stored on your device. Using private/incognito browsing prevents this.
  • Targeted government surveillance may be able to detect VPN usage. But they can’t access your activity.
  • VPN connections can sometimes be detected and blocked by streaming sites like Netflix.
  • You can still be tracked if logged into accounts and services.

Despite these limitations, a quality VPN provides the best all-around protection against tracking available. Even state-level actors would have difficulty gathering any meaningful personal data on someone using a secure VPN. It’s an essential tool for online privacy.


I hope this detailed overview has helped explain exactly how VPNs keep you safe from online tracking. By routing your traffic through an encrypted tunnel to hide your IP address and encrypt network data, VPNs prevent ISPs, hackers, malware, and even government entities from monitoring your online activity.

Selecting a reputable VPN that undergoes regular audits and has clearly stated privacy policies ensures you get the full protective benefits. With so much personal data being collected online today, a VPN gives you peace of mind that your information and browsing history won’t end up in the wrong hands.
