VPN Myth: What It Does and Doesn’t Do

Listen on:

Virtual Private Networks (VPNs) are marketed as all-in-one security solutions, but their capabilities are often exaggerated. While essential for certain tasks, a VPN only solves a narrow set of security problems. Relying on a VPN alone can give you a false sense of security, leaving other risks exposed.

This episode breaks down the true function of a VPN and what it cannot protect you from.

What a VPN Absolutely Does

A VPN's core function is to create a secure, encrypted tunnel between your device and a server located elsewhere.

  • Hides Your Location and IP Address: When connected, your true geographical location is masked. Only the VPN server's location is visible to websites and network administrators.
    • Value: This is perfect for bypassing geo-blocking or maintaining privacy on public Wi-Fi.
  • Encrypts Your Connection: A VPN scrambles all data sent between your device and the VPN server.
    • Value: It prevents local network administrators, governments, or hackers on public Wi-Fi from monitoring your traffic.
  • Secures Public Wi-Fi: It prevents other users on the same unsecured coffee shop or airport network from intercepting your data.

What a VPN Absolutely Does Not Do

A VPN is not antivirus software, nor is it a cloak of digital invisibility.

  • It Doesn't Block Malware: If you click a malicious link or download an infected file, the VPN will not stop the malware from infecting your device.
  • It Doesn't Stop Phishing: If you voluntarily enter your password into a fake login page (phishing), the VPN encrypts that data transmission, but it cannot prevent you from being scammed.
  • It Doesn't Make You Anonymous: Your activity can still be tracked by social media platforms, search engines, and other sites through cookies, device fingerprinting, and login data—regardless of your IP address.
  • It Doesn't Fix Weak Passwords: If your account is protected by a weak or reused password, a VPN offers no protection against a remote brute-force attack.

Actionable Takeaway

Use a VPN to secure your traffic on public Wi-Fi and to mask your location. But always combine it with strong, unique passwords, Multi-Factor Authentication, and a healthy skepticism toward emails and links. A VPN is a powerful tool, not a complete security strategy.
