How we help manufacturing buyers source technology.
OT/IT convergence · Multi-plant operators.
TL;DR
What buyers in manufacturing need to know.
Manufacturers source technology at the OT/IT boundary. The plant floor speaks one set of protocols, the corporate stack speaks another, and the vendor that can keep them separate without making operations grind to a halt is the one worth signing.
The pain points
What's actually broken in manufacturing technology sourcing right now.
Specific to this industry. We see the same five problems across nearly every engagement.
- OT vendors who refuse to terminate into SASE fabric, forcing direct internet exposure.
- MSSP coverage that markets OT visibility but cannot actually parse OT-protocol traffic.
- Plant-floor downtime tolerance much lower than any vendor SLA actually covers.
- Multi-plant networking projects scoped at 90 days that consistently run 180.
- ERP integration costs that surface only after the SD-WAN cutover is in motion.
The vendor landscape.
Categories we source for manufacturing: Multi-plant SD-WAN with OT segmentation · UCaaS for distributed offices · MSSP with OT-aware threat detection · cloud workload security.
Regulatory environment: CMMC for defense contractors, ITAR/EAR for regulated manufacturers, increasing NIS2 attention for European subsidiaries, sector-specific compliance (FDA for medical device, USDA for food manufacturers).
Integration dependencies: ERP systems (SAP, Oracle, NetSuite, Epicor), MES platforms, SCADA networks, vertical-specific software (MasterControl, Trackwise, ETQ for regulated manufacturers).
Every vendor mentioned in the questions below is in our active supplier pool. Buyer-stack software (EHR, ERP, AMS, DMS, and similar) is named freely as integration targets — these are systems we source contracts to integrate WITH, not vendors we source ourselves.
Three questions buyers actually ask
The high-intent questions answered.
How do we segment OT and IT networks without breaking plant-floor operations?
OT/IT segmentation done well requires SD-WAN that can route OT traffic on isolated VLANs with explicit policy controls. Cato Networks, Aryaka, Open Systems, and Fortinet (via partners) all carry mature OT-aware configurations. The vendor selection depends on whether your OT vendors are willing to terminate into the SASE fabric or insist on direct internet routing.
Which MSSPs actually understand manufacturing-specific threats?
Manufacturing MSSP coverage needs to understand OT-specific threats: PLC compromise, supply-chain attacks via vendor remote access, ransomware targeting production. Trustwave, Ontinue, and eSentire layer OT visibility on top of IT MSSP. The integration into your existing OT vendor relationships matters more than the marketing collateral.
What does a 12-plant SD-WAN refresh look like for a mid-market manufacturer?
A 12-plant refresh in 2026 looks like SD-WAN or SASE with cellular failover, OT segmentation, and centralized policy management. Cato, Aryaka, Open Systems, Bigleaf, and Fortinet carry mature 10-50 plant configurations. The implementation timeline is typically 90-180 days. The vendor selection is more about post-deployment operations than feature set.
