VPNs Explained: When You Need One (and When You Don't)
A VPN hides your traffic from the network you're on and your IP from the sites you visit. It doesn't make you anonymous or stop malware.
What it protects
Your traffic on public Wi-Fi, from your internet provider, and your IP address from websites.
What it doesn't
It doesn't stop phishing or malware, and the VPN company can see your traffic instead, so trust matters.
Free VPNs
Many free VPNs make money from your data. If it's free, check who runs it and how it's paid for.
Pick one
Look for an independently audited no-logs policy, WireGuard support and a kill switch.
Reaching home?
To access your own home network, use Tailscale instead of a commercial VPN.
FAQ
Do I need a VPN at home?
Not for security on your own Wi-Fi. People use them for privacy from their ISP or for travel.
Does incognito mode do the same?
No. Incognito only stops your browser saving history on your device.
