IT/OT Middleware
Connect the plant to the business, and back again
Your business systems know what should be made. Your machines know what is being made. FlowFuse keeps the two in step, in both directions, at every plant, on one platform IT governs and OT runs.

Where IT/OT integration breaks down
Most manufacturers already connect the plant to the business. The cost is in how it was done, and it usually shows up in the same six places.
- 01
Every link is a project
Each new pairing of system and machine needs its own build, its own budget and its own owner.
- 02
Integrations nobody owns
Scripts and gateways written years ago still run production, and the people who wrote them have moved on.
- 03
A vendor for every connection
Each protocol and each system brings its own tool, licence and support contract to manage.
- 04
IT and OT work apart
IT can't see what runs at the plant, and the plant can't wait in IT's queue.
- 05
Security reviews stall the rollout
Connecting the plant network to business systems is where most integration projects lose months.
- 06
Data only flows one way
Reports come out of the plant, but orders and recipes still go back in by hand.
What FlowFuse gives your business
Replace the gateways, scripts and point tools between your plants and your business with one platform. Fewer systems to maintain, faster rollouts, and every plant run the same way.
Connected Operations
Every machine and system, connected both ways
Connect each system once, and data moves both ways: decisions reach the line, results reach the business.
- PLCs, SCADA and historians reach ERP, MES and the cloud, older equipment included
- Orders and recipes reach the line, and counts, scrap and downtime reach the business
- Data waits at the edge when a link drops, and sends once it returns

}Standardized Data
One data model at every plant
A raw register means nothing to a business system. Data arrives named, in context and the same from every site.
- Whatever format a device sends, each value arrives named, with its unit and place in the plant
- All sites report the same way, so plants compare like for like
- Business systems receive what they need, not every raw reading

Real-Time Visibility
The apps your business systems can't provide
ERP and MES were never built for the floor. With FlowFuse Dashboard, your team builds the apps that fill those gaps.
- Operators get screens made for their line, machine and shift
- Supervisors, maintenance and plant leaders see their area live
- New apps follow your priorities, not a vendor's roadmap

Device Management
Run at the edge, manage every plant from one place
A small central team can look after every site, however many you add.
- The health and version of every device, at every plant, in one view
- Fixes and updates go out remotely, with no trip to site
- Devices are managed in groups by plant, line or region

Faster Rollouts
Prove it once, roll it out everywhere
Each new plant becomes a deployment, not another integration project.
- Every change is tested in staging before it reaches production
- One proven integration deploys to every plant, each with its own settings
- A bad change rolls back in one click
Enterprise-grade security, without opening your network
Plants connect outward, so the OT network stays segmented and no inbound firewall ports are opened. FlowFuse is SOC 2 Type I and Type II certified, with single sign-on, role-based access and audit logs, and runs self-hosted or air-gapped where the cloud isn't an option.

Why IT and OT teams choose FlowFuse
In their own words, from both sides of the plant.
“FlowFuse is like a Swiss Army knife that I can drive most of our IT systems from, versus having 10 different vendor relationships, 10 different point solutions, and then having to build practices around all that.”
“I built out the FlowFuse deployment from scratch: machine monitoring, machine dashboards, ERP integration. What FlowFuse gave us was revision control and a platform the whole team could own. That made the deployment self-sustaining.”
