Not too much, as we’ll stay focused on the practical use of VPN and avoid technical terms as possible.As described in this article a VPN provides a secure, encrypted connection in a network. That network can be an office network, a public WiFi network, or the regular, public Internet. Below, we briefly describe four types of VPN expressvpn recensioni.
1. Mobile VPN
A mobile VPN allows you to maintain a VPN connection to a network despite changing hotspots, for example, or switching from mobile Internet to WiFi. This type of VPN is therefore ideal when you travel.
2. Remote VPN
A remote VPN is often used by companies to give their employees, who work from home or on the road, access to the office network. With this type of VPN you therefore have a kind of gatekeeper (a so-called ‘gateway’) that determines whether you are authorized to access the network with migliori Netflix VPN nel Italia.
3. Site to site VPN
A ‘site to site’ VPN is basically a variant of the remote VPN. This type is also commonly used by companies, but mainly by smaller offices that use VPN in communication with other offices. Again, a gateway is used but in both networks (the sending and receiving side). The employee connects to the VPN gateway which then sends the data encrypted over the Internet to the receiving gateway.
4. Hardware VPN
The above three types of VPN are software-based VPNs. However, there is also a hardware VPN. This type of VPN is a powerful and stand-alone VPN solution that offers a number of advantages over software VPN solutions, such as a firewall and ‘load balancing’ (distributing required computer capacity to perform heavy tasks across multiple computers/servers).
The hardware VPN is a lot pricier than a software VPN (500 to 1000 euros vs. 50 to 100 euros). Because of these advantages but also because of the higher cost, hardware VPNs are almost only used by larger companies.
