ZeroTier develops software that automatically handles the complexities of networking across physical network boundaries, dealing with mobility and unifying cloud & edge to free customers from spending time building their projects and focus on running their business. Our network virtualization technology delivers the power of enterprise software-defined networking to every device, service, and application whether it’s located at the edge or in the cloud. It’s capable enough for large businesses with complex networking needs but easy enough that tens of thousands of regular people use it to do simple things like play games online or connect to their home PC from their mobile device.
We work to solve the hard technical problems underlying decentralized application development so you can deliver applications that offer a positive low-friction user experience while avoiding the cost, liability, and security/privacy impact of a large highly involved cloud presence.
ZeroTier was founded by Adam Ierymenko in 2015.
The company’s network virtualization software is used by millions of users in over 230 countries and territories. For more information about us please visit our website at www.zerotier.com
