NetBird

NetBird develops an open-source Zero Trust network security platform built on WireGuard, the modern VPN protocol. The platform is designed to simplify secure private networking by replacing traditional VPN infrastructure with an approach that integrates directly with identity providers supporting OpenID and multi-factor authentication. By open-sourcing its core technology, NetBird makes its codebase publicly available for inspection and contribution.

The company's stated mission is to democratise network security, making Zero Trust architectures accessible to organisations of all sizes rather than reserving them for large enterprises with dedicated security budgets. This positions the product as a VPN alternative that aims to reduce the operational complexity typically associated with secure network management.

NetBird operates in the intersection of network security and cybersecurity, focusing specifically on the Zero Trust security model - a framework that assumes no implicit trust within a network and requires continuous verification. The technical stack centres on WireGuard, a protocol known for its relatively small codebase and performance characteristics compared to older VPN protocols such as OpenVPN and IPsec.
