+# NexusGuard SD-WAN Suite
+
+> Enterprise Zero-Trust SD-WAN with WireGuard
+
+NexusGuard is a production-grade, zero-trust SD-WAN solution built with Go, Vue 3, and WireGuard. It enables stealth VPN tunneling, centralized IPAM, and real-time network isolation via Linux `nftables` — all managed through a futuristic glassmorphism dashboard.
+
+## Key Highlights
+
+- **Zero-Attack Surface** — No public registration. Admin accounts created via CLI only.
+- **Stealth Agent** — WireGuard config injected into memory. No files written to `/etc/wireguard/`.
+- **Real-time Firewall** — Per-peer nftables rules synced to kernel instantly.
+- **Cross-Platform** — Agent runs on Linux (daemon), Windows (tray + service), and macOS (tray).
+
+## Tech Stack
+
+`Go` · `Vue 3` · `WireGuard` · `PostgreSQL` · `Redis` · `nftables` · `gRPC` · `Docker`
