What is a VPN?

A complete guide to Virtual Private Networks, online privacy, and why every internet user needs protection.

What is a VPN?

A Virtual Private Network (VPN) creates a secure, encrypted connection between your device and the internet — a private tunnel that shields your online activity from hackers, ISPs, advertisers, and surveillance.

When you connect through a VPN, your real IP address is hidden and replaced with one from a VPN server of your choice, protecting your identity and enabling access to region-restricted content.

How Does a VPN Work?

A VPN works in three steps:

  • Encryption: Your device encrypts all outgoing data using AES-256 before it leaves.
  • Tunneling: Encrypted data travels through a secure tunnel to a VPN server.
  • Forwarding: The VPN server decrypts and forwards your request; responses return via the same encrypted path.

Why Do You Need a VPN?

  • Protects your data on public Wi-Fi (airports, hotels, coffee shops)
  • Hides your browsing history from your ISP
  • Prevents targeted advertising based on your behaviour
  • Enables access to geo-restricted streaming and websites
  • Secures remote work connections
  • Bypasses censorship in restrictive regions

VPN vs. Antivirus — Do You Need Both?

Yes. A VPN protects your privacy and encrypts traffic — but it doesn't scan for malware. Antivirus protects your device from infected files. ESET VPN combines both in one suite, giving complete protection without separate apps.

How to Choose a VPN

  • No-log policy: The provider must not store records of your activity
  • Strong encryption: AES-256 is the industry standard
  • Server coverage: More locations means more flexibility
  • Proven reputation: 30+ years of trusted security expertise (ESET)
