What is a VPN?
A virtual private network (VPN) is technology that enables users to send and receive data across shared or public networks as if their devices were directly connected to a private network.
It acts as an intermediary between the device and the Internet. Once configured and enabled, all traffic sent and received passes through the VPN. A mobile VPN can also keep sessions open regardless of changes to the physical connection, whether with different connection points or different IP addresses.
How does a VPN work?
A VPN acts as a virtual encrypted tunnel between a host server and a device, so that users are protected as they operate across the Internet. They are configured at operating system level, on a network that captures all outgoing connections. This means that VPNs capture the traffic of all applications on the computer, from browsers to online games, and including system updates that run in the background.
VPN services are used by all types of users -not just IT security professionals- and, in general, their popularity is increasing. However, use of these networks is not free from risks, as not all of them can be trusted. Despite the fact that using a VPN allows you to remain anonymous, you still have to trust the provider, especially if you have access to confidential websites. The use of professional networks, such as Panda VPN, ensures adequate protection for your activities with the guarantee of a renowned security provider.
Protecting your Internet browsing
This is particularly important with mobile devices, which often connect to public Wi-Fi networks, in places like hotels and airports, which are not always secure. That's why many companies use these VPNs to give remote employees access to local or corporate networks. A VPN can be configured on any device with the client installed, regardless of the user's location.
VPN services provide an extra layer of security, offer access to geographically restricted content, hide Web content from your ISP and generally hide your location and online activity. Thanks to strong encryption, only the host server of the VPN can access the data.
Providers of VPNs for mobile devices allow a nomadic connection, i.e., not from a fixed location but on the move (for example, when users move between different mobile networks or Wi-Fi hotspots). A mobile VPN maintains the virtual connection to each application at all times, even if the location changes, keeping session logins transparent to the user.
VPNs can help establish more secure Internet browsing parameters and block ads and other potential threats, even while on the move. As with fixed networks, the traffic is also encrypted and only the sender and recipient can read the information. Mobile VPNs can be used to encrypt data on devices before sending it, so it can only be decrypted by a specific server, without affecting other traffic.
