What’s changing
IT/OT convergence
What it exposes
New paths into production environments
Why it matters to the business
Downtime, safety, and revenue risk
Manufacturing
An attack doesn’t have to destroy data to stop production.
A plant can go dark because enterprise IT, a vendor VPN, or an engineering workstation opened a path to the floor. We test those paths production-safe — planned around maintenance windows — so you can ship on time and protect what sets you apart.

Why this matters now
The risk is moving. The emphasis has to move with it.
Most manufacturing disruption still starts in IT. Convergence, vendor remote access, and engineering workstations are how it reaches the floor.

Ransomware on enterprise IT

Safety-system and run-rate risk
In this environment
What we look for on a plant network
Corporate IT and the floor are no longer separate problems. We map the bridges attackers actually use — then test them without taking a line down.
Corporate IT and plant networks
The office side that still opens most engagements.
OT, PLCs, and HMIs
Controllers and interfaces that cannot be treated like a laptop.
Engineering workstations
The trusted pivot between design, historians, and the floor.
Remote access and vendors
Integrator VPNs, RDP, and remote tools that outlive the project.
Design and recipe repositories
IP that walks out even when production stays up.
The question we prove
Can an attacker move from corporate IT into production?
We walk the segmentation gaps, vendor access, and engineering workstations that turn a phished inbox into a production event — passively and low-impact first, then only as far as plant leadership has approved.
The path we walk
A path from the office to the floor
This is the progression we see in real OT engagements. We find it, prove it, and close it — around the windows the plant can actually give us.

What leadership sees
What a finding means for the plant
An open port on a PLC is not the briefing. Whether that path can stop a line — and when you can afford to close it — is.
Consequence
Which line, shipment window, or safety system the path can interrupt.
Priority
Sequenced by uptime and safety — not a generic severity score.
Regulation
Mapped to IEC 62443 zoning and the OEM audits customers already send.
Ownership
Plant OT, corporate IT, and the integrator who still has a token.
Remediation
Hardening planned around maintenance windows, with production-impact notes.
Leadership visibility
Portal so operations and the board see residual risk in run-rate language.
Frameworks this maps to
NIST CSF
Executive baseline for plant and corporate leadership.
IEC 62443
OT security zoning for industrial environments — tied to the path we walked.
Customer OEM audits
Evidence packs for supply-chain security questionnaires.

The work continues after the assessment
A one-time plant test is not a production-security program. Remediation, retesting, and readiness stay tied to the windows you can actually use.
Remediation on maintenance windows
An OT-specific risk register with production-impact notes your team owns.
Retesting that proves the floor is closed
The same IT-to-OT chain, walked again, after the window you scheduled.
Tabletops for downtime decisions
Who isolates a line, who calls the vendor, and how long shipping can wait.
Training for plant and office staff
Workshops that help people act fast on alerts and limit scrap or downtime.
Continuous exposure monitoring
Corporate and plant-adjacent systems stay in view between assessments.

attack paths triaged before peak production
OT segmentation gaps and legacy PLC exposure surfaced in week one — before peak season, while the plant could still schedule the work.
