Every industrial edge gateway faces the same fundamental challenge: prove its identity to a cloud platform, establish a secure connection, and keep that connection alive for months or years — all while running on hardware with limited memory, intermittent connectivity, and no IT staff on-site to rotate credentials.

Getting authentication wrong doesn't just mean lost telemetry. It means a factory floor device that silently stops reporting, burning through its local buffer until data is permanently lost. Or worse — an improperly secured device that becomes an entry point into an OT network.

This guide covers the practical reality of device provisioning, from the first boot through ongoing credential management, with patterns drawn from production deployments across thousands of industrial gateways.
