A manufacturer or warehouse operator is effectively running two IT environments at once: the office network everyone thinks of as “IT,” and the operational floor - barcode scanners, forklift-mounted terminals, production line controllers, and increasingly IoT sensors monitoring equipment. Treating those as one network, managed the same way, is where most of the problems we see actually start.
OT/IT Convergence - Why It Matters
Factory floor and warehouse equipment used to be isolated by default - a PLC (programmable logic controller) running a production line had no reason to touch the internet. That's changed: production data now feeds into reporting dashboards, equipment sends telemetry to monitoring platforms, and warehouse management systems need real-time connectivity to scanning devices. The efficiency gain is real, but it also means a compromised office laptop can, if the network isn't properly segmented, have a path to systems that were never designed with security in mind.
Network Segmentation for the Floor
The single most important control for a manufacturing or warehouse environment is proper network segmentation - separate VLANs for the office network, the warehouse/scanning network, and any operational technology (OT) or production equipment. This matters more here than in most office environments because a lot of floor equipment is older, can't run modern endpoint security software, and simply can't be patched the way a laptop can. Segmentation, not the equipment itself, ends up doing most of the security work. Our guide to network security for Perth businesses covers the underlying principles in more depth.
For operators with more than one site - a warehouse and a separate office, or multiple depots - SD-WAN is increasingly the practical way to connect them reliably without the cost of dedicated circuits between sites.
Connectivity Across a Warehouse Floor
Warehouse WiFi has its own set of challenges that a standard office design doesn't account for: metal racking and shelving that blocks signal, high ceilings, large open floor areas, and forklift-mounted scanners that need to roam between access points without dropping connection mid-pick. A proper site survey - not a guess based on floor plan alone - is the only reliable way to get coverage right in a space like this. Our guide to business Wi-Fi design covers what that process actually involves.
Inventory, ERP, and Warehouse Management Systems
Barcode and RFID scanning integrated with a warehouse management system (WMS) or ERP platform - Cin7, Unleashed, MYOB Advanced, or SAP Business One are common choices for Perth manufacturers and distributors - depends entirely on reliable connectivity to function properly. When WiFi coverage is patchy, scanners either lose connection mid-task or queue scans to sync later, which is a common, avoidable source of stock discrepancies and duplicate or missed entries.
Business Continuity for Production
Downtime on an office network is disruptive. Downtime on a production line or in a warehouse picking process is lost output, missed dispatch windows, and in some cases wasted material - the cost accumulates by the hour rather than being absorbed quietly. Recovery time expectations for production-critical systems are typically tighter than for general office IT, and that should be reflected explicitly in backup and recovery planning rather than assumed. Our guides to RTO and RPO and building a disaster recovery plan cover how to set realistic recovery targets for systems like these.
Device and Access Management
Shared floor terminals and handheld scanners are common in manufacturing and warehouse environments, often logged in under a generic device account rather than tied to an individual staff member. That's convenient day to day, but it removes any audit trail if stock goes missing or a system is misused, and it makes offboarding harder - a shared login can't be selectively revoked for one departing staff member. Our guides to insider risk and offboarding cover why individual accountability matters even in a shared-device environment.
Frequently Asked Questions
Why does a warehouse network need to be separated from the office network?
Older floor and warehouse equipment often can't run modern security software or be patched the way a laptop can, so proper network segmentation, separate zones for office, warehouse, and production equipment, does most of the actual security work. Without it, a compromised office laptop can potentially reach systems that were never designed with security in mind.
Why is WiFi coverage harder to get right in a warehouse than an office?
Metal racking, high ceilings, and large open floor areas all interfere with signal in ways a standard office design doesn't account for, and forklift-mounted scanners need to roam between access points without dropping connection mid-pick. A proper site survey, rather than a guess based on the floor plan, is generally the only reliable way to get this right.
What causes stock discrepancies between a WMS and actual inventory?
Patchy WiFi coverage is one of the more common, avoidable causes, since scanners either lose connection mid-task or queue scans to sync later, which creates duplicate or missed entries. Fixing the underlying connectivity issue usually does more for data accuracy than any change to the software itself.
Should production and warehouse systems have different backup targets than office IT?
Generally yes, downtime on a production line or in a picking process tends to cost more per hour than office downtime, in lost output and missed dispatch windows, so recovery time expectations for these systems should be set explicitly rather than assumed to match general office IT.
