OT / IT segmentation review
We map where production systems touch the corporate network and the internet, and help separate them — the single control that moves a manufacturer's application from decline to quote.

The loss here isn't a data breach. It's the line going down.
For a manufacturer, the expensive day is the one where production stops. Ransomware that reaches the shop floor turns a security incident into a revenue incident, and the path there usually runs straight through a flat network where IT and operational technology share a segment.
The exposure
What underwriters and attackers actually look at
Carriers ask whether operational technology sits on the same network as IT — and 'same flat network' is a selectable, failing answer on forms from At-Bay and Hanover. The fix is segmentation before you apply; the loss being priced is downtime on production, not stolen records.
The program
What we operate for you
The same managed security program we run for every client — 24/7 SOC-monitored detection, identity protection, and security awareness training, operated end-to-end — tuned to manufacturing & industrial.
MDR on the IT systems that bridge to the floor
Managed detection and response on workstations, engineering laptops, and the servers that schedule and feed production — where the ransomware actually lands before it spreads.
Tested, immutable backups
Backups that are MFA-protected or immutable and restore-tested, so a production-system encryption event is a bad afternoon, not a bad quarter.
End-of-life inventory
Internet-facing end-of-life software with no extended support is a failing application answer. We inventory it and get it segmented or replaced before underwriting sees it.
Fit
Who this is for
- Small and mid-market manufacturers with shop-floor OT/ICS
- Job shops and fabricators running scheduling or ERP on the same network as machines
- Manufacturers whose customers now require a security attestation
- Owners who can't afford a multi-day production stoppage

Do You Need CMMC? A Small Manufacturer's Guide to the 2026 Rules
If you make anything for the defense supply chain — even as a sub-tier subcontractor — CMMC may now gate your contracts. Here's who's actually in scope, what Level 2 requires, and what non-defense manufacturers should do instead.

For a small manufacturer, the expensive cyberattack isn't data theft — it's the ransomware that stops the line. Manufacturing is the most-attacked industry, and downtime is the real loss. The exposure and the fix.

Manufacturing & Industrial: common security questions
Does a small manufacturer need cybersecurity compliance?
It depends on your contracts. Defense-supply-chain manufacturers handling Federal Contract Information or Controlled Unclassified Information fall under CMMC. Commercial manufacturers have no federal mandate — but face the same ransomware-downtime and cyber-insurance pressures, with the same control set.
What's the biggest cyber risk for a manufacturer?
Ransomware that stops the production line. Manufacturing has been the most-attacked industry in IBM's X-Force Threat Intelligence Index for five straight years (2025 data), because a halted line is exactly the leverage attackers want. Segmenting the office (IT) network from the plant (OT) network is one of the highest-impact defenses.
How much does managed cybersecurity cost for a manufacturer?
Managed coverage starts at $15 per device per month (Foundation, no minimum). The Protected and Complete tiers — adding identity protection, security awareness training, and SIEM — are billed per seat for teams of five or more. The one-time Cyber Insurance Readiness Sprint is a fixed fee from $1,500 (three tiers up to $3,500).
How fast can you get a plant protected?
The Cyber Insurance Readiness Sprint runs seven business days and maps where your IT and OT networks touch and where backups stand. Managed monitoring can begin onboarding in the same week.
