Reseller & License Architecture

Centralized Nexus Admin Security

Nexus ERP clients operate entirely offline with zero mandatory cloud connectivity for daily invoicing or inventory checks. Licensing, hardware verification, and reactivation are managed via Nexus Admin's hardened cryptographic API.

Hardware Identity (MAC & System Fingerprint)

Each activation locks to the physical motherboard and network controller preventing illicit key distribution.

Single-Click Re-activation Workflow

When customers replace equipment, authorized administrators or resellers can safely release machine bindings with full audit logging.

Automated Misuse & Multi-Machine Detection

Repeated attempts from multiple machines automatically flag in the security ledger for administrative review.
