Most operators cannot answer an auditor's first question with confidence. EOS Modus turns the OT estate into structured, living data, then answers CAF, NIS2, IEC 62443 and NIST CSF from one control set, instead of four parallel spreadsheets and a fortnight of copy and paste.
Not because teams are careless, but because the tooling was never built for operational technology. IT GRC platforms assume an estate that patches on a Tuesday. OT does not work like that.
Vendor documentation is years old. The commissioning spreadsheet was last touched by an engineer who left in 2021. The OEM has a list, but it is theirs, not yours, and it stops at the turbine.
Every compliance question that follows inherits that uncertainty, so the answers are hedged and the evidence is thin.
The same control gets evidenced separately for each, by different people, at different times, against different versions of the truth. Findings contradict each other and nobody can say which is right.
The effort is real. The assurance it produces is not proportionate to it.
Ofgem, an insurer, a board committee, or an incoming OFTO asks for the position. What follows is archaeology, chasing screenshots, emails and half-remembered decisions across three organisations.
The pack gets built, the audit passes, and eleven months later the whole exercise starts again from zero.
EOS Modus does not start with a questionnaire. It starts with the estate.
Every control system, zone, asset, data flow, access record and third-party connection in scope, held as structured data rather than a spreadsheet. Vendor, model, firmware, location, owner, criticality, and the conduit it sits behind.
Nothing else in Modus works without it. That is deliberate. A risk register that does not resolve to a real asset is an opinion, and a control that cannot name what it protects will not survive an audit. Build the spine once, keep it current through change control, and every other module inherits ground truth for free.
Take them in any order. Most operators start with the register and the framework mapping, then add depth where the regulator is looking hardest.
Evidence a control once. Modus maps it to every framework and standard that asks for it, and shows you where the genuine gaps are rather than where the paperwork is thin.
EOS Modus is designed to be run by the team that owns the estate. If your OT compliance position lives in a consultant's laptop, this is the alternative.
EOS Modus is in development with a small group of operators shaping the module set. If you are carrying an OT compliance obligation and the current approach is not scaling, we would like to talk.
