In an OT environment, the wrong change at the wrong time doesn't just cause an outage — it can create a safety incident. Every Destria engagement follows the same five-stage sequence, in the same order, every time.
We start by establishing what's actually on your network — not what the as-built diagrams say. Using passive discovery methods that don't risk destabilizing legacy PLCs or safety systems, we build a verified asset inventory and map communication flows across your environment.
Assessment findings become an architecture — not a slide deck. We translate risk findings into a zone-and-conduit model mapped to your Purdue levels, accounting for the legacy platforms, vendor constraints, and change windows that actually govern your plant.
Segmentation, access controls, and endpoint hardening get deployed in controlled stages — never as a single high-risk cutover. Each stage is validated before the next begins.
Facility-wide IT, data systems, AI tooling, and payment infrastructure get rolled out on top of the hardened foundation — sequenced to avoid unplanned downtime and validated against the design before go-live.
A hardened environment needs upkeep, not a one-time project. We stay engaged for ongoing monitoring, patch governance, and a direct line to the team that actually built your environment — not a generic help desk.
Why this order matters: Every stage depends on the one before it. Hardening without an accurate asset inventory means securing devices you don't know exist — or missing ones you do. That's why we don't skip Assess, even for facilities that think they already know their network.
