Cybersecurity in machine safety: what changes for robotics teams?

TL;DR: The EU Machinery Regulation will require manufacturers to treat software, data, connected devices, and foreseeable malicious attempts as part of machinery safety from 20 January 2027, which pulls cybersecurity into the safety lifecycle for robots and software-defined machines, according to VicOne. Security and evidence now matter before shipment and during operation, because unsafe behaviour can emerge after deployment.

Editorial analysis by NHI Mgmt Group, based on content published by VicOne: “When AI Moves: Why the EU Machinery Regulation Matters for Physical AI Security”.

Key questions

Q: What is the main failure mode when robotics security is treated separately from safety?

A: The main failure mode is assuming that safe hardware and validated software remain safe after shipment even when access paths, configuration, or models change.

Q: Why does the EU Machinery Regulation change how teams think about cybersecurity risk?

A: It changes the risk model because cybersecurity can now affect whether a machine meets its safety obligations.

Q: What are the signs that a robot is no longer operating within its intended safety boundary?

A: Warning signs include unexpected changes in command paths, unusual update activity, altered configuration, anomalies in perception or movement, and behaviour that no longer matches the validated operating envelope.

Practitioner guidance

• Map every safety-relevant digital dependency Identify the software, firmware, AI models, sensors, remote connections, update paths, and control interfaces that can change how the machine moves, stops, perceives, or responds.
• Assess robot risk before deployment Combine vulnerability scans, AI model review, and scenario-based validation to test whether selected weaknesses could change physical behaviour before shipment.
• Monitor runtime behaviour continuously Track command paths, communication channels, exposed interfaces, update channels, and anomalous activity after deployment so unsafe changes are visible before they affect physical safety.

Bottom line: The article’s central point is that machine safety now depends on controlling digital paths that can alter behaviour after shipment.
