What Is a VPN?
A VPN, or Virtual Private Network, sends your internet traffic through an encrypted tunnel to a server run by the VPN provider. Websites then see that server's IP address instead of yours.
It's a useful privacy tool, but it's often oversold. Here's what it really does.

What a VPN protects
Your IP address, which it swaps for the server's, hiding your rough location.
Your traffic on untrusted networks, since it's encrypted. That matters most on public Wi-Fi.
Your browsing from your ISP, which can no longer see which sites you visit.
What a VPN does not do
It doesn't make you anonymous. Logins, cookies, and browser fingerprinting still identify you.
It doesn't stop malware or scams on its own.
It doesn't speed up your connection. It usually adds a small slowdown.
Should you use one?
If you often use public Wi-Fi, want to keep your browsing private from your ISP, or need to appear in another region, a reputable no-logs VPN is worth it. For browsing at home on your own network, the benefit is smaller. Choose a paid provider with a clear no-logs policy and a kill switch.

Best overall
NordVPN
Fast, with a huge server network and independently audited no-logs policy. A safe all-rounder.
Be careful. Running a VPN costs money, so some free services make it back by logging or selling your data. A trustworthy paid VPN, or a reputable free tier with limits, is safer.
Will a VPN slow me down?
A good one only a little. Encryption and the extra hop add some overhead, but quality providers stay fast enough for streaming and calls.
