A VPN encrypts traffic between your device and the VPN server, protecting it from local network snooping—especially on public Wi-Fi at cafes, airports, and hotels.
What VPNs do and don't do
VPNs hide browsing from your ISP and local attackers. They do not make you anonymous against determined nation-state actors, nor do they protect against malware or phishing if you click malicious links.
Choosing a provider
Prefer no-logs policies audited by third parties. Avoid free VPNs that sell user data. Check jurisdiction and whether the service supports modern protocols like WireGuard.
Combine layers
VPN + HTTPS + updated software + skepticism toward unsolicited links = practical defense. Security is layered, not single-tool dependent.
