Do I need a VPN?
Short answer
A VPN is useful on untrusted networks such as public Wi-Fi, and for hiding your browsing from the local network or internet provider. It does not make you anonymous, stop phishing or remove malware, and it shifts trust to the VPN provider, so choose one carefully.
The details
Most websites already use HTTPS, which encrypts what you send. A VPN adds a layer by hiding which sites you visit from the network you are on. Businesses often use VPNs or zero-trust access tools to reach internal systems securely.
Avoid free VPN apps with unclear business models; read the provider’s privacy policy and logging terms.
Terms explained
- VPN
- A VPN (virtual private network) creates an encrypted tunnel between your device and a VPN server, hiding your traffic from the local network and internet provider.
- HTTPS and TLS
- HTTPS is HTTP protected by TLS encryption, which keeps data between a browser and a website private and tamper-resistant and confirms the site controls its domain.
- Malware
- Malware is any software designed to harm, spy on or gain unauthorized control of a device, network or account.
- Phishing
- Phishing is a fraudulent message, usually email, that impersonates a trusted sender to trick people into revealing credentials, paying money or running malware.
