ZeroTier, Inc.

ZeroTier, Inc. specializes in network virtualization software that collapses the complexity of traditional VPN, MPLS, and SD-WAN technologies into a single global fabric. The company’s flagship offering, ZeroTier One, behaves like a distributed, planet-spanning Ethernet switch, automatically discovering nodes and stitching them together into encrypted Layer-2/Layer-3 networks that can run atop any existing IP infrastructure. Typical deployments include IT administrators who need to connect branch offices, cloud instances, and remote laptops into one coherent intranet without touching firewalls or routers; DevOps teams that want isolated test environments that span on-prem and public clouds; gamers seeking LAN-like latency for multiplayer sessions; and IoT vendors that must reach thousands of embedded devices behind carrier-grade NAT. Configuration is reduced to a 16-digit network ID and an optional rules engine that enforces micro-segmentation, traffic shaping, and 802.1X-style admission control, all managed from a web console or REST API. The client installs on Windows, macOS, Linux, FreeBSD, iOS, Android, and popular NAS platforms, creating a virtual port that appears to the operating system as just another NIC, so existing applications require no modification. ZeroTier’s software is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always pulling the latest release and supporting batch installation alongside other applications.
