OpenVNet is what you would call a network hypervisor. It allows you to fully virtualize your network infrastructure and create any network topology that you have in mind.

Software Defined Networking done right

Start Using OpenVNet



  • Don't be bound by network hardware limitations
  • Create any network topology you have in mind regardless of hardware
  • Change your topology on the fly without touching any cables


  • Connect any regular network device to an OpenVNet virtual network
  • No need to install any clients on devices in virtual networks
  • The entire network topology is controlled from a single Web API


  • OpenVNet virtual networks can work together with regular "physical" networks.
  • Connect regular physical networks with OpenVNet virtual networks in the same L2 segment.
  • Any conventional router can route between regular networks and OpenVNet virtual network.


  • Highly customized solutions
  • OpenVNet is developed by a small and flexible team
  • That makes it possible to tailor it exactly to your needs


  • Secure the servers in your data center using Security Groups.
  • Define groups with specific firewall restrictions and assign servers to them.
  • Specialize your firewall on a per-server basis. Every network interface connected to OpenVNet has its own personalized firewall.
