VPN

A virtual private network routes your internet traffic through an encrypted tunnel to a remote server, hiding your IP address from the sites you visit and your traffic from your local network.

Why it matters

A VPN solves two real problems: it stops your ISP from logging which sites you visit, and it lets you appear to be browsing from a different country to bypass geo-blocks. It does NOT make you anonymous (the VPN provider sees your traffic) and it does NOT block malware. Treat a VPN as one tool in a privacy stack, not the whole stack.

The VPN-for-everything pitch is marketing. The legitimate use cases are: public Wi-Fi protection, ISP-snooping mitigation, and geo-bypass. For threat protection you still need an antivirus.

Best practices

Pick a provider with an independent audit (PwC, Deloitte) of their no-log policy. Self-hosted reviews mean nothing. Use the WireGuard or Lightway protocol when available; OpenVPN is fine but slower. Test for DNS leaks at dnsleak.com after every install.

Don't run a free VPN. The business model for free VPNs is selling your traffic data, which defeats the purpose entirely.

Frequently asked

Does a VPN make me anonymous?

No. The VPN provider can see what you do, your bank still recognizes you when you log in, and your behavior on sites still fingerprints you. A VPN hides your IP from sites and your traffic content from your ISP. That is the actual scope.
