Netmaker is a software-defined networking platform that enables organizations to build and manage secure overlay networks using the WireGuard protocol. The platform is designed to replace traditional VPN setups with a mesh networking approach that supports zero-trust security principles. Core capabilities include: - Creation and management of software-defined networks (SDNs) across distributed environments - Support for site-to-site connections, remote access, and edge device management - On-premises deployment option for organizations requiring full infrastructure control - Features such as Egress, Ingress, Relays, and Access Control Lists (ACLs) - A centralized dashboard and CLI for network configuration and monitoring - An API for embedding enterprise networking into third-party platforms Netmaker targets a range of use cases including distributed team connectivity, multi-location office networking, edge and IoT device fleet management, Kubernetes cross-cloud networking, AI/ML infrastructure connectivity, and legacy VPN replacement. The platform is used by companies in finance, public transport, audiovisual, and software development sectors, among others. The platform consists of a server-side orchestration layer and a client agent (Netclient) that configures WireGuard and routing rules on endpoints. It is available as a cloud-hosted service and as a self-hosted, on-premises deployment. Netmaker is backed by Y Combinator and reports usage by over 500 companies worldwide.
