ZeroTier

ZeroTier, Inc. is a networking software and cybersecurity company with a freemium business model based in San Francisco, California. ZeroTier provides a proprietary network platform and software tools, SDKs, and related commercial products and services to create and manage virtual software-defined networks. The company's flagship end-user product, ZeroTier One, offers a client application that enables devices, such as PCs, phones, servers, routers, and embedded devices to securely connect to zero-trust peer-to-peer virtual networks. ZeroTier also helps enterprises and public-sector organizations reduce their attack surface by replacing exposed networks with identity-based, end-to-end encrypted connectivity. Devices form direct peer-to-peer connections whenever possible, with optional gateways for controlled access to centralized services or the internet. In July 2024, ZeroTier announced that it had closed $13.5 million in a Series A funding round, bringing the company's total funding to approximately $15.6 million. The round was led by Battery Ventures, with participation from 7 percent Ventures, Airbridge Equity Partners, Anorak Ventures, Bonfire Ventures, First In Ventures, and Grand Enterprises B.V.
