A typical DESSS OT Security Assessment delivery runs 6 steps, with the final step reached around weeks 5–8. Complex integrations, multi-entity scope, or regulated environments extend that — the discovery session produces a dated plan for your case rather than an average.
Every step closes with named deliverables — Attack path diagram, Attack surface inventory, Attestation, Authorisation letter, Evidence pack, Executive summary, Exposure findings, Impact analysis — so progress is visible, auditable, and reviewable rather than a status colour on a slide.
