Why Use a VPN?
A VPN serves a wide range of legitimate purposes - From protecting sensitive data on public Wi-Fi to accessing content unavailable in your region. Understanding which use case applies to you helps you choose the right provider and configuration.
Top Reasons People Use a VPN
| Use Case | How a VPN Helps | Recommended Feature |
|---|---|---|
| Public Wi-Fi security | Encrypts traffic so café, airport, or hotel networks cannot intercept passwords or session cookies | AES-256 encryption, always-on VPN |
| ISP privacy | Prevents your internet provider from logging and selling your browsing history | No-logs policy, DNS leak protection |
| Geo-restriction bypass | Access streaming libraries, news sites, or services blocked in your country | Streaming-optimised servers, obfuscation |
| Remote work security | Securely connect to company resources as if you were in the office | Split tunnelling, reliable kill switch |
| Torrenting / P2P | Hides your IP from peers in the swarm, reducing exposure to copyright notices | P2P-optimised servers, port forwarding |
| Travel censorship | Access blocked websites (Google, WhatsApp, social media) in restrictive countries | Obfuscated servers, stealth protocol |
| Price discrimination | Some airlines and e-commerce sites show different prices based on your location | Server in lower-cost region |
What a VPN Cannot Do
A VPN is a privacy tool, not a magic cloak. It does not:
- Prevent websites from tracking you via cookies, login sessions, or browser fingerprinting - Use our privacy guide for additional steps.
- Protect you from malware, phishing, or social engineering attacks.
- Make you fully anonymous - Your VPN provider can still see your traffic if they choose to log it. Choose a provider with an independently audited no-logs policy.
- Encrypt traffic end-to-end between you and the destination server - HTTPS still handles that layer separately.
VPN vs Other Privacy Tools
| Tool | What It Hides | Speed Impact | Best For |
|---|---|---|---|
| VPN | IP from websites, traffic from ISP | Low–moderate | Everyday privacy & streaming |
| Tor | IP + routing path (multi-hop) | High | Maximum anonymity, journalists |
| Proxy | IP only (no encryption) | Very low | Simple geo-bypass, not security |
| HTTPS only | Content only (not IP or metadata) | None | Basic encryption, not privacy |
