Your OT, SCADA, and industrial IoT assets were built to run for decades. From power grids and manufacturing lines to EV chargers and building systems, these environments now sit in the blast radius of threat actors whose tactics evolve and grow more effective every week.
The constraints are brutal:
You can’t casually patch or replace PLCs, RTUs, and HMIs without risking downtime.
Field devices live on dirty, shared networks you don’t control.
VPNs and exposed ports create standing entry points attackers can probe for years.
Traditional IT security was never designed for this world, but Xiid’s Terniion is.
Terniion eliminates the attack surface for OT and industrial IoT without touching firmware or shutting down the line.
