If you log into your bank account, check your email, or use social media over an unsecured connection, hackers may be lurking, waiting to snap up your login credentials. When you’re hooked up to an encrypted VPN network, not only is all your internet data shielded from hackers and sniffers, but your true location and identity remain hidden from your internet service provider (ISP), the government, marketers, or anyone else who may be snooping on your local network. Establishing an encrypted, private network is exactly what a VPN connection does - and this encrypted layer offers an array of security, privacy, and performance benefits. VPNs establish a secure connection to the internet by encrypting all your online traffic and routing it through a point-to-point connectionbetween your device and the VPN server. VPNs strengthen your personal security and privacy online because they help you do the following: Encrypt your internet connection Having explained the VPN basics, let’s discuss what a VPN is used for in more detail. This combination of security and flexibility makes VPNs extremely versatile. Not only does a VPN connection encrypt your browsing and other web traffic, it can give you access to a freer internet by letting you configure your settings to alter your virtual online location. Stream freely and get around location-based content blocks. Secure your data over public Wi-Fi networks. There are many benefits of using a VPN - VPNs let you: VPNs work by adding a layer of encryption to the data that passes through your internet connection. VPNs hide your IP address behind a different IP address (often in another country) provided by the VPN server. When the website data arrives back at your device, your VPN client (VPN app) decrypts the data. The VPN server then encrypts the data sent back by the web server and sends it on to you. To the website, your IP address will appear to be the one attached to the VPN server. The VPN server decrypts this, hides your true IP address, and sends the data to the website’s server. Once the VPN tunnel is established, your device sends the VPN server encrypted information such as a website you want to visit.

A full tunnel means all data goes through the VPN tunnel, whereas a split tunnel sends only traffic that you, or your employee, want to be protected (for example, Instagram activity could be exempt). 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.
