Introduction to Defined Networking

Defined Networking provides Managed Nebula: a secure networking solution that handles the complexity of overlay networks for you. Our platform gives your team centralized control over hosts, security policies, and network configuration—without the operational burden of manual certificate and key management.

Core components of Managed Nebula​

  • Admin web app to manage hosts, groups, firewall rules, and overlay IPs from a single dashboard
  • Web service that automates enrollment and updates across your entire fleet
  • Host client software—powered by Nebula—that automatically updates certificates, keys, and configuration (including the groups-based firewall)

Think of it as enterprise-grade networking that just works: you get the security and performance of Nebula with the ease of a fully managed platform.

About Nebula open-source​

Managed Nebula is built on Nebula, our open-source overlay networking tool. If you prefer to self-manage keys, certificates, and host configuration, Nebula open-source is available and actively maintained. Most organizations, however, choose Managed Nebula to eliminate operational overhead while maintaining complete control over their network.
