Commercial and Procurement FAQs

What do you need before ot and iot security kickoff?

We begin with Asset and Protocol Discovery (Week 1) and align system owners, access paths, approvals, and rules of engagement before execution starts.

How do procurement and legal reviews fit this engagement?

We provide statement-of-work scope boundaries, data-handling expectations, and execution controls so procurement and legal teams can review with clarity.

What is included after delivery?

We walk your team through ot and iot exposure register prioritized by operational impact. and translate findings into owner-mapped remediation checkpoints.

Can this engagement be phased by business priority?

Yes. We can phase delivery by critical assets and priority outcomes, including lower risk of cyber-driven process disruption..

Technical FAQs

Can testing be done without production interruption?

Yes. We use passive and staged approaches aligned to maintenance windows.

Do you cover both OT and IoT assets?

Yes. We cover industrial control environments and connected IoT pathways.

How is safety handled during security changes?

Safety owners are integrated into planning, approval, and validation activities.

The engagement improves cyber-physical resilience through protocol-aware assessments, segmentation, and coordinated safety governance.
