NetBird

NordLayer competes directly for the enterprise and team-based remote access market by offering a managed ZTNA solution that replaces traditional VPNs.

GoodAccess provides a cloud-based ZTNA platform that directly challenges NetBird's positioning as a modern, simplified network access solution.

While focused on DNS filtering, it overlaps with NetBird by utilizing WireGuard to secure and manage network traffic.

This tool competes in the managed device space, specifically targeting organizations already using SOTI for mobile device management.

ZeroTier is the closest functional peer to NetBird, providing a virtualized P2P network layer for distributed infrastructure.
