On an operational estate the objective is rarely data. It is visibility, control, and the ability to keep running safely — and every recommendation has to be written against a maintenance window rather than against a best practice.
OT security fails when a corporate playbook is applied to an estate that cannot accept it. These are the three questions that keep it honest.
Shared identity, shared DNS, and an engineering laptop that lives on both sides. Independence is asserted far more often than it is verified.
The single most common blank on an org chart is the boundary between corporate IT and operations. Both sides assume the other holds it.
A recommendation that requires an unscheduled outage is not a recommendation. Sequencing against real maintenance windows is most of the work.
On an operational estate the objective is rarely data. It is visibility, control, and the ability to keep running safely. Choose an entry point.
Five stages, from the way in to the thing the attacker came for. What changes between paths is how long each stage stays invisible.
OT security is constrained by availability in a way corporate security is not. Every recommendation we make here is written against a maintenance window, not against a best practice.
Four stages, every engagement. Hover a stage to see what happens in it.
Three moves. Two of them are ours, and the one in the middle is deliberately somebody else’s.
Detection engineering, triage, response and the reporting that goes with it. This is an operational service with a named duty owner, not an advisory engagement.
Effectiveness testing of a service Orvix runs is performed by a party that does not report to the team running it. Where a regulator or a board needs the result to carry weight, that party is not Orvix.
Detection gaps found by the test become engineering work with a date against them, and the re-test is run by the tester rather than by us.
Three engagements inside this pillar. Start with the question you can name, or take the whole estate at once.
Detection and response run as a service, with the dwell time written down.
The attacks that arrive as a convincing person rather than as a file.
The estate where availability outranks confidentiality and patching is not free.
Thirty minutes. If you cannot immediately name who owns the boundary between your corporate and operational estates, that is the conversation.
