What a VPN Actually Does

A Virtual Private Network (VPN) creates an encrypted tunnel between your device and a VPN server, hiding your traffic from your local network or internet service provider and masking your IP address from the sites you visit.

What a VPN Protects Against

  • Eavesdropping on unencrypted public Wi-Fi networks.
  • Your ISP tracking which websites you visit.
  • Basic IP-based location tracking by websites.

What a VPN Does Not Protect Against

  • Malware already on your device.
  • Phishing attacks that trick you into entering credentials.
  • Tracking through cookies, browser fingerprinting, or logged-in accounts.
  • A VPN provider that logs and sells your activity — choose reputable providers with clear no-log policies.

A VPN is a privacy and encryption tool — it is not a replacement for antivirus software, strong passwords, or cautious browsing habits.

Choosing a VPN

Look for providers with independently audited no-log policies, strong encryption standards, and transparent ownership. Free VPNs sometimes monetize user data, so read privacy policies carefully.
