It also depends on whether you use full or split tunneling - the main difference is defined by what traffic goes through the VPN. The level of protection you receive when using a VPN depends on the type of tunneling protocol used. A VPN wraps an outer packet (a protocol) around the original data packet, encrypting it so it can’t be intercepted. At the core of VPN tunneling is a process called encapsulation. Before being sent over the internet, all data is split into packets. A VPN server is a typical internet server configured with VPN software. VPN tunneling is the process of securing your device’s connection with a VPN server. That’s why VPN connections are crucial to your online privacy and security.Ī VPN funnels your internet traffic through an encrypted tunnel between your computer and a VPN server. When not hooked up to a VPN network, all your internet traffic is potentially exposed to your ISP, the government, advertisers, or other people on your network.
This hides your IP address and secures your data, preventing others from intercepting it. How does a VPN work?Ī VPN works by using encryption protocols to funnel all your internet traffic through an encrypted tunnel - a virtual private network -between your computer and a remote VPN server. Strictly speaking, the VPN meaning refers only to the private network connection itself - the actual software app that manages your device’s VPN connection is technically called a VPN client - but the two cybersecurity terms are often used interchangeably.
