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 |

How We Evaluate VPNs
Every recommendation in our VPN guides is weighed against the same five criteria:
- No-logs policy and audits - We prioritise providers whose no-logs claims have been verified by independent auditing firms, and we note real-world events (subpoenas, server seizures) that tested those claims.
- Leak-test results - A VPN must not expose your real IP, DNS servers, or WebRTC addresses. You can run the same checks we use with our free VPN Leak Test.
- Speed impact - We favour providers supporting modern protocols (WireGuard, or equivalents like NordLynx and Lightway) that keep overhead low.
- Jurisdiction - Where a provider is incorporated determines which governments can compel it to hand over data.
- Price transparency - Clear renewal pricing and honest refund terms. We avoid quoting specific prices in guides because promotions change frequently - Always check current pricing on the provider's site.
Our assessments are based on published third-party audits, vendor documentation, and our own leak-testing tooling - We do not have insider access to any provider's infrastructure. These pages are reviewed periodically and updated when audits, ownership, or features change.
Once you have picked a provider, two practical checks matter more than any review: if your connection fails, see how to fix a VPN that won't connect; and to confirm you are actually protected, learn how to test if your VPN is working.
