A VPN (Virtual Private Network) encrypts your internet traffic between your device and a VPN server. It’s one of the simplest ways to reduce exposure on public Wi‑Fi and to hide your home IP address from the websites you visit.

What a VPN helps with

  • Safer browsing on public Wi‑Fi (reduces local snooping).

  • Masking your IP from websites (they see the VPN server’s IP).

  • Reducing ISP-level visibility into your browsing destinations (depending on DNS).

What a VPN does NOT do

  • Stop cookies/trackers by itself—browser privacy settings still matter.

  • Make you fully anonymous—your VPN provider can still see traffic metadata.

  • Protect you from phishing/malware—use 2FA and basic security hygiene.

How to choose a VPN

  • Clear privacy policy (what they log, for how long, and why).

  • Modern protocols (WireGuard/OpenVPN) and strong encryption defaults.

  • Speed and reliability (nearby servers, stable connections).

Bottom line: a VPN is a strong privacy layer, but it works best when combined with HTTPS-first browsing, tracker blocking, and strong account security.
