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 is built for these requirements: EU-hosted GDPR-native architecture, OPC-UA connectivity, edge gateway OT isolation, and SOC 2 Type II certification.

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.

Fabrico's architecture answer: machine data flows outbound only from an edge gateway in the DMZ between OT and IT networks. No inbound connections from Fabrico cloud to the OT network. The edge gateway initiates all connections, it's the same principle as a firewall with no inbound rules.

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.

Fabrico provides all of these on request during evaluation. Vendors who cannot provide them are telling you something important about their security posture.

Fabrico's OT connectivity standards:

• OPC-UA: Primary connectivity for modern PLCs (Siemens S7-1500, Allen-Bradley, Beckhoff, Omron). Standard-based, widely supported, no vendor lock-in.
• Modbus TCP: Legacy PLC connectivity and process instrument integration.
• S7comm: Siemens legacy PLC protocol for S7-300/400 environments.
• MQTT over TLS: IoT sensor connectivity with encrypted transmission.

IT governance controls available in Fabrico:

• SSO/SAML integration with Azure AD, Okta, and Google Workspace
• Role-based access control with granular permission levels
• Complete user action audit log accessible to administrators
• API authentication via OAuth 2.0 with token expiry
• GDPR-compliant EU data hosting with data processing agreement

Fabrico passes enterprise IT security review. Request the security documentation package as part of evaluation. SOC 2 report, data flow diagrams, penetration test summary, and GDPR documentation, before committing to any OEE vendor for production connectivity.
