OEE Software for IT and OT Managers: Connectivity, Security, and Deployment Without the Headaches

Key Takeaways: OEE software connects to your most sensitive operational technology, production PLCs, machine controllers, and OT networks. IT and OT managers need to validate security architecture, data residency, integration standards, and vendor access controls before any OEE platform touches production infrastructure. Fabrico offers EU hosting on AWS, a GDPR Data Processing Agreement, ISO/IEC 27001 certification and PLC connectivity over OPC UA, Modbus, PROFIBUS, PROFINET, EtherNet/IP and EtherCAT. Confirm your controllers with us in a demo.

OEE software for IT managers in manufacturing starts with one question: how does machine data travel from the OT network to the cloud, and what security architecture governs that path?

The answer reveals whether a vendor has thought through OT security or is assuming it's someone else's problem.

Ask every vendor, us included, for that path in writing. A clean answer shows data flowing outbound only, with no inbound connections to the OT network.

Verify these before any OEE platform touches production infrastructure:

• Network architecture diagram: Request a diagram showing exactly how machine data travels from PLC to cloud. No inbound connections from internet to OT network should appear anywhere on that diagram.
• SOC 2 Type II report: Request the most recent report (within 12 months). Review Section 7 (Availability) and Section 9 (Confidentiality) specifically.
• Data residency: Written confirmation of where data is processed and stored. For EU operations: GDPR compliance documentation.
• Penetration testing: Summary of most recent third-party pentest and remediation status of findings.
• Vendor access log: Confirm that all vendor access to your production data environment is logged and accessible to your team on demand.
• Data portability: Contractual guarantee of bulk data export in open formats (CSV, JSON) without vendor involvement.

Ask every vendor for these during evaluation, and us too. Where a vendor has no such report, ask what it offers in its place.

Fabrico connects over OPC UA, Modbus, PROFIBUS, PROFINET, MQTT, EtherNet/IP, EtherCAT, IO-Link and HTTP. Confirm your controllers with us in a demo. Notes on common ones:

• OPC-UA: On Fabrico's PLC link, and common on modern PLCs. Standard-based and widely supported.
• Modbus TCP: On Fabrico's PLC link, and common on older PLCs and process instruments.
• MQTT over TLS: On Fabrico's protocol list, and common for IoT sensors, with encrypted transmission.

IT governance controls available in Fabrico:

• SSO/SAML integration (custom)
• Role-based access control with granular permission levels
• Complete user action audit log accessible to administrators
• REST API and webhooks
• GDPR-compliant EU data hosting with data processing agreement

Fabrico holds ISO/IEC 27001, ISO 9001 and ISO/IEC 20000-1, hosts production data in an EU region on AWS, and provides a Data Processing Agreement. Request the full security documentation package from every vendor as part of evaluation, meaning current certificates, data flow diagrams, penetration test summary and GDPR documentation, before committing to any OEE vendor for production connectivity.
