OT SECURITY
OT security for plants, utilities and industrial systems
We find risks in your industrial networks without putting operations at risk.
What is an OT security assessment?
An OT security assessment reviews the operational technology that runs physical processes, such as PLCs, SCADA, HMIs and industrial networks. It maps assets, checks segmentation between IT and OT, reviews remote access and finds weaknesses using safe, mostly passive methods, aligned with standards such as IEC 62443.
In OT, downtime is not an option.
We use safe, non-disruptive methods built for live industrial environments.
