Industrial networks are an attack surface. We harden them.
Most OT and IoT deployments were architected before security was a procurement requirement. TRACIO assesses where your RTLS, AGV, sensor, and PLC traffic sits in the Purdue model, what’s actually exposed, and what to fix first. Vendor-neutral, framework-aligned (IEC 62443, NIS2, NIST CSF, ISO 27001). We don’t sell tools — we design the architecture and the remediation plan, then verify it.
Three OT-layer failure modes we see again and again.
The findings repeat across verticals. Naming them is the first step in closing them.
PLCs and tags share the office VLAN
The original network was flat because that was the fastest path to go-live. Today, an RFID reader, a PLC, a meeting-room TV, and a finance laptop are all one broadcast domain away from each other. A single compromised endpoint reaches the line.
No segmentation between OT and IT
Purdue levels exist on the architecture diagram but not in the firewall. East-west traffic between the MES and the BI warehouse flows unfiltered. Lateral movement is free of charge for anyone who lands a phishing payload in HR.
Remote access is a back door
OEM vendors hold permanent VPN credentials so they can support machinery. Nobody knows who is logged in right now, what they touched last week, or whether the shared service account is still in use by the engineer who left.
Six workstreams. Run together. Framework-aligned.
Every workstream maps to an IEC 62443 foundational requirement and produces evidence your auditor and your CISO will both accept.
OT cyber posture assessment
Map every IoT/RTLS/PLC device, classify by criticality, document actual data flows, identify the gap to IEC 62443-3-3 SL2 or SL3.
Zone & conduit design
Segment by Purdue level, define the conduits between zones, and specify firewall rules in vendor-neutral form so any procured firewall can implement them.
Identity for things and people
Device identity (certificate-based), service-account hygiene, integration with your IdP (Entra, Okta, Ping) for the human side.
Hardened remote access for vendors
Jump host, MFA, session recording, time-bounded access for OEM vendors needing to support machinery without owning a permanent VPN.
OT-aware SOC integration
Mirror traffic to a SOC that understands Modbus, OPC UA, MQTT, S7, EtherNet/IP — not a generic IT SIEM with no protocol context.
OT incident response runbook
Pre-built runbooks for ransomware, tag-fleet compromise, AGV malfunction. Tabletop-tested before you need them.
Three ways to bring us in.
Sized to where your OT estate actually is — from a first-time posture check to embedded remediation alongside your IT/OT team.
Posture audit · 4–6 weeks
Full map, gap analysis, prioritised remediation roadmap. Fixed-fee.
Architecture & design · 8–12 weeks
Zone/conduit design, identity model, monitoring spec, vendor RFP for tooling.
Embedded remediation · 4–9 months
We sit alongside your IT/OT team through the actual remediation. We exit when KPIs are met.
