Industry fit

Protection that respects how a plant operates.

Manufacturers increasingly connect business IT, production networks, suppliers, remote engineers, and cloud services. Security must reduce pathways into operations while respecting safety, uptime, equipment lifecycles, and maintenance windows that differ from ordinary office environments.

Who this is forDiscrete and process manufacturers, industrial operators, suppliers, engineering businesses, and organizations supporting connected production environments.

What must stay protected

Start with the systems the organization depends on.

Production and OT networks

Industrial control systems (ICS), controllers, supervisory systems, engineering workstations, and plant communications.

Intellectual property

Designs, recipes, process knowledge, product data, engineering files, and research systems.

Remote and vendor access

Maintenance connections, integrators, equipment vendors, remote sites, and privileged engineering access.

Supply-chain operations

Planning, inventory, ERP, logistics, supplier communications, and systems needed to keep production moving.

Reference scenario

A vendor needs access to one production cell.

An equipment supplier needs a maintenance session while other production lines keep running. Plan the permitted path, the maintenance window, and the person who can stop the session before granting access.

01
Named vendor
A named account and an approved maintenance window.
02
Controlled entry
Remote access limited to the approved destination and purpose.
03
IT/OT boundary
Explicit permitted flows between business systems and the production zone.
04
Production cell
The plant owner approves work on the controller and verifies safe operation.

Illustrative planning sequence, not a customer deployment. Confirm the actual architecture, supported integrations, and service scope for your environment.

The decision to agree

Record who may revoke remote access immediately and who must approve any isolation or policy change that could interrupt a production process. Do not assume that an office endpoint response is safe for a controller.

The evidence to keep

Keep the access approval, configured source/destination rules, available gateway or remote-access logs, change record, and plant acceptance result. Confirm which signals are actually available; network monitoring does not establish that every OT device is visible.

Threat landscape

Risks shaping security priorities in Manufacturing.

Each priority connects prevention, monitoring, response, and reporting to the operating realities of the industry.

OT and IT convergence

New connections can create unintended pathways between business systems and production assets.

Edge DefenseApply segmentation, deny-by-default policy, intrusion prevention, and monitored access at critical boundaries.

Ransomware stopping production

Compromise of shared services or engineering systems can create costly operational downtime.

NBX: MDR, EDR, XDRMonitor connected activity, investigate suspicious behavior, and escalate containment priorities quickly.

Intellectual-property theft

Design and process information can be stolen quietly through user, endpoint, or third-party access.

SIEMCorrelate relevant logs and events to improve visibility, investigation, and documented follow-up.

Remote-access exploitation

Persistent vendor or maintenance pathways can expose critical systems when access is broad or weakly monitored.

Secure SD-WANUse encrypted connectivity and centrally managed network policy across plants, remote sites, and approved connections.

Frameworks and obligations commonly relevant

NIST CSF CMMC NIST SP 800-171 DFARS ITAR NERC CIP where applicable

Applicability depends on the organization, data, contracts, and jurisdiction.

Recommended service mix

A focused plan for Manufacturing.

The mix is a starting point. We map final coverage to the actual environment, obligations, and internal capacity.

Shared responsibility

Managed security works best when ownership is explicit.

Final responsibilities depend on the contracted scope, technology, and organization. This is the operating split to establish during design.

Industry FAQ

Your questions about Manufacturing cybersecurity.

How can we protect equipment that cannot be patched on the office schedule?

Inventory the equipment and its dependencies, restrict permitted network paths, control vendor access, and agree on maintenance windows with the plant and equipment supplier. Record the residual risk and validate changes without disrupting safety or production. Compensating controls reduce exposure; they do not remove the underlying vulnerability.

Will a security alert automatically shut down a production line?

Containment authority must be agreed during design. Document actions that can be taken immediately, actions requiring plant approval, and the escalation path when the primary contact is unavailable. A generic reference architecture does not authorize automatic isolation of industrial equipment.

Can the existing industrial network stay in place?

Start by mapping the current IT/OT boundaries, permitted flows, remote access, equipment constraints, and available logs. Scope changes around the existing environment and test them during an approved window. Supported integrations and device visibility must be confirmed before promising coverage.
