How the tunnel works
Your internet provider can usually see that you connected to a VPN, while destination services generally see the VPN server’s IP address. The VPN company may still process connection data, so provider choice matters.
Common uses
People use VPNs on untrusted Wi-Fi, for remote work, to reduce local network visibility, or to connect to an organisation’s private systems.
Important limitations
A VPN does not remove malware, stop phishing, hide activity inside logged-in accounts, or make unauthorised copying lawful. Browser cookies and device fingerprints can still identify users.
Good habits still matter
Use multi-factor authentication, current software, unique passwords, encrypted websites, and cautious download practices alongside any VPN.
