How a VPN Works
Whenever you connect with a VPN, your system (laptop, phone, or tablet) first establishes a secure connection to a VPN server operated by a VPN provider. All your internet traffic is then routed through this server. This process masks your real IP address and replaces it with the IP address of the VPN server. As a result, your on-line identity and location are hidden from websites and tracking tools.
The most critical function of a VPN is encryption. VPNs use encryption protocols to scramble your data, making it unreadable to anyone who intercepts it. Whether you’re checking emails on public Wi-Fi or accessing sensitive information, a VPN ensures that your data stays secure.
Key Benefits of Using a VPN
