Downtime is measured in revenue per minute; ransomware crosses from email to MES in one wrong click. intSignal runs enterprise IT, MDR, and recovery alongside OT and ICS security alignment—so engineering, operations, and IT stop debating whose dashboard is “real.”
We scope with your controls engineers and safety owners: patch windows that respect production, remote access that does not punch holes through segmentation, and vendors managed with the same discipline as tier-one suppliers.

Line up
Runbooks that treat production calendars as immovable objects—coordinating IT changes, OT maintenance, and security containment without improvising on the night shift.
OT
segmentation & visibility aligned to ISA/IEC-style practice
MDR
enterprise + plant-adjacent telemetry as authorized
DR
MES, ERP, and historian tiers with tested restore order
Pressures
Operational risk
Legacy PLCs next to modern MES, OEM remote tunnels nobody documented, and ERP upgrades that collide with month-end close. Supply-chain attacks land through smaller partners first.
intSignal delivery
Named owners for identity, plant-adjacent Windows and Linux, SOC escalations, and vendor access reviews—with tickets your quality and internal audit teams can trace.
Plant-to-enterprise
Quick links from plant-adjacent systems to enterprise services—each card opens a depth page when you need more detail.

Where we fit
High-mix lines, robotics cells, and engineering workstations that need CAD and PLM without leaking IP through consumer cloud sync.
Historians, batch servers, and safety-instrumented systems where change freezes are contractual with production.
Regional plants, joint ventures, and contract manufacturers—consistent identity and network policy without HQ becoming a bottleneck.
OT assurance
We do not replace your process hazard analysis—but we can execute IT and security work that respects it.
Documentation of zones, conduits, and firewall rules your insurers and customers increasingly ask for.
Time-bound, monitored sessions for OEM support—not permanent VPNs into Line 3.
IT and OT-adjacent visibility coordinated with maintenance systems where in scope.
Test rings and rollback tied to production windows your operations calendar owns.
Containment options pre-approved with engineering—not generic “isolate everything” scripts.
Evidence packages that map to ISO 9001-oriented IT controls when your program requires it.
Leadership mosaic
Service levels for MES interfaces, label printers, shop-floor thin clients, and quality lab systems—so “IT ticket” is not the excuse for missed shipments.
PAM-aware patterns, badge integration where deployed, and contractor access that expires on schedule.
Email and web controls, vendor risk touchpoints with procurement.
Analytics and integration where data classification and IP agreements allow.
Architecture, modernization, and handoff to managed run-state.
Engagement
Line topology, MES/ERP dependencies, OT asset sketch, vendor access map, prior incidents and near-misses.
Joint IT–OT backlog: segmentation gaps, identity sprawl, logging blind spots, unowned OEM tunnels.
Execute changes in approved windows; tune SOC use cases for plant-relevant alerts.
Monthly metrics, DR tests with line restart criteria, continuous improvement tied to production KPIs you choose.
Why manufacturers choose intSignal
Every change ticket carries rollback and a named operations contact—not “we will monitor.”
Enterprise and plant-adjacent alerts correlated where telemetry allows—fewer duplicate bridges during incidents.
OEM and integrator access governed with expirations and evidence—not shared passwords in a spreadsheet.
Documentation maintained so you can rebadge staff or switch partners without losing tribal knowledge.
FAQ
No. We align IT and security services with your controls integrator and OEM contracts. PLC logic, safety PLCs, and SIS changes remain with qualified engineering partners unless your SOW explicitly includes agreed automation tasks.
We align patch and vulnerability SLAs to your production calendar, document risk acceptance when you defer, and escalate when compensating controls are required—not silent drift.
DLP, collaboration governance, and endpoint controls scoped to your classification scheme—implemented with engineering and legal so legitimate collaboration is not accidentally strangled.
Share plant count, primary ERP/MES stack, OT maturity, and top downtime or security drivers. We respond with a proposed service map, RACI, and commercial approach.
