One partner. Three ways to run it.
The whole journey under one multi-year agreement, one governance cadence and one evidence trail in OTMATIX. Authority and approvals always stay with you. Pick the model that fits.
Senior practitioners run the programme with you inside OTMATIX, anchored by a Virtual OT CISO. You retain authority and approval rights; the programme never stalls when your team is stretched.
Let’s secure every layer of your plant.
Begin with an OT Security Posture Assessment and ThePlantWalk. An evidenced view of your OT risk, and a clear path to the level of security you choose to hold.
