Practical Zero Trust Plan for OT: 90‑Day Roadmap
🔒 The article reframes zero trust for operational technology (OT) by focusing on practical, non‑disruptive steps that align with regulatory requirements and operational realities. It proposes a 90‑day plan: Days 1–30 prioritize mapping assets and identities at IT/OT boundaries; Days 31–60 contain vendor remote access to gain early wins; Days 61–90 build a simple maturity scorecard and narrative. The approach emphasizes targeted controls, governance alignment, and measurable progress rather than abstract architectures.
