DNClient

The client provides a peer‑to‑peer VPN interface for networks built with the Nebula overlay technology. It creates encrypted tunnels between any hosts, allowing devices on different clouds, data centers, office locations, or home networks to communicate securely without manual IPSec or site‑to‑site configuration. Each connection is authenticated and encrypted using the Noise Protocol Framework, and the software includes a built‑in firewall and certificate authority for managing host certificates and access policies.

Designed for macOS, the client supports automatic failover, routing traffic through relays when a direct path is unavailable, and leverages hardware‑accelerated AES‑NI to achieve near line‑speed performance on supported CPUs. It can handle heavy usage, supporting thousands of concurrent tunnels on a single host while maintaining compliance‑ready encryption that meets standards such as GDPR, HIPAA, and SOC 2.

The interface offers simple host management, automatic configuration updates, and complete audit logging, allowing administrators to focus on connectivity rather than low‑level networking details. The software is marked as stable and is intended for users who need a reliable, zero‑trust overlay for global, multi‑cloud environments.
