Going Deeper: How to Actually Test and Vet a VPN

Marketing pages make every VPN sound identical, so the real work is verifying claims yourself. A few practical checks will tell you far more than a feature table.

Look past the word "no-logs"

A no-logs promise is only as good as the evidence behind it. Read the privacy policy itself, not the summary, and note what is collected at signup, during payment and while connected. Some providers publish independent audits of their infrastructure or policies; check what was audited, by whom, and how recently. Also consider jurisdiction: the country a company operates from shapes which legal requests it can receive and how it must respond.

Know your protocols

WireGuard is modern, lean and generally fast. OpenVPN is mature, widely reviewed and flexible, though often slower. IKEv2/IPsec handles network switching well on mobile. Be wary of providers that only offer proprietary protocols with little public documentation, and avoid anything still relying on PPTP.

Run your own leak tests

• Check for DNS leaks while connected, so your lookups are not still going to your ISP.
• Test for WebRTC leaks in your browser, which can expose your real IP.
• Confirm IPv6 traffic is either tunnelled or blocked.
• Pull the network cable or toggle Wi-Fi to see whether the kill switch really stops traffic.

Measure speed fairly

Test at different times of day, against nearby and distant servers, and compare each result to your unprotected baseline. One quick test on launch day says little about everyday performance.

Match the tool to your threat model

A VPN shifts trust from your ISP or the café Wi-Fi to the provider; it does not make you anonymous, stop malware or prevent phishing. For travellers on hotel networks, a reputable commercial service is usually enough. If you need to reach a home lab, self-hosting WireGuard may suit you better. Free VPNs deserve extra scrutiny, since running servers costs money and that money has to come from somewhere.
