### ProxyingThe VPN server acts like a **proxy**, or stand-in, for your web activity: Instead of your real IP address and location, websites you visit will only see the IP address and location of the VPN server.This makes you more **anonymous** on the internet.### AuthenticationEstablishing a secure connection is a tricky problem solved by clever mathematics in a process called **authentication**.Once authenticated, the VPN client and VPN server can be sure they are talking to each other and no one else.### TunnelingVPNs also protect the connection between client and server with tunneling and encryption.Tunneling is a process by which each data packet is **encapsulated** inside another data packet. This makes it harder for third parties to read in transit.### EncryptionData inside the tunnel is also **encrypted** in such a way that only the intended recipient can decrypt it. This keeps the contents of your internet traffic completely private. Even your internet service provider won’t see it.## Types of VPN### Commercial VPNA commercial VPN, also called a personal VPN or a consumer VPN, is a private service offered directly to individuals, usually for a fee.ExpressVPN is such a VPN service because it directly caters to the privacy needs of its customers.### Corporate VPNA corporate VPN, also called a business VPN, allows an organization’s remote employees to connect securely to the internet as if they were physically present in the office.Unlike commercial VPNs, however, corporate VPNs are meant to protect the privacy of the company and not necessarily the individual.### Self-setup VPNSome tech experts and DIY hobbyists choose to set up their own VPN using their own equipment.Self-setup VPNs, however, do not provide the protection of shared IP addresses, server locations in multiple countries, or many other features enjoyed by commercial VPN users.## FAQ
