Brochure · EN — Siemens Energy brochure (2026) introducing the Noedra Shield suite, the grid-security arm of the Noedra digital framework. Shield delivers a purpose-built cyber-physical security ecosystem for OT/ICS grid environments, organized along the NIST Cybersecurity Framework: identify & assess (asset inventory, risk prioritization and compliance reporting), protect (OT zero-touch deployment, secure remote access), detect (insider threat detection, continuous OT/ICS network monitoring of ICCP, DNP3, Modbus and IEC 61850), respond (incident response and threat modeling) and recover (incident recovery plan execution). The document positions Shield as unifying visibility, protection and control across substations, assets and control infrastructures without disrupting mission-critical operations.
Noedra is Siemens Energy's digital framework — described as the "Mind of the Grid" — that connects Grid Technologies' intelligent solutions, from sensing and control systems through software and advisory, into a single coherent ecosystem.
The framework turns grid data into clarity, coordination and confident action, helping operators manage growing complexity. Each Noedra suite represents a specific way this intelligence acts across the grid; together the suites protect, sense, structure and guide energy systems toward a resilient future.
Within the Noedra ecosystem, Shield is the suite responsible for security across the entire grid. It focuses on protecting OT/ICS environments, strengthening cyber-physical resilience, and ensuring regulatory compliance across substations, assets and control infrastructures.
Because Shield is connected with the other Noedra suites, it provides real-time situational awareness that eliminates cyber-physical security blind spots — unifying visibility, protection and control across all operational layers of the grid.
Power grids are more connected, automated and digitally dependent than ever, which increases exposure to cyber-physical threats, regulatory compliance requirements and vulnerability risks — especially within OT/ICS environments. Legacy assets, siloed systems and partial solutions impede business continuity; control rooms and security operations centers (SOCs) need a unified cyber-physical security solution built specifically for grid critical infrastructure, capable of delivering real-time visibility, protection and control without disrupting mission-critical operations.
The brochure defines four requirements for an effective grid cybersecurity strategy: a unified visualization of OT/ICS assets across all layers of the Purdue OT model; secure remote access from the control room and SOC to the substations; compliance-readiness reporting across global cybersecurity standards; and the ability to identify & assess, protect, detect, respond and recover from cyber-physical threats in real time.
In an interconnected grid, even small unnoticed incidents can escalate quickly, and latent vulnerabilities may stay undetected until a crisis occurs. Adhering to the NIST cybersecurity framework (CSF) helps organizations proactively minimize exposure, strengthen grid security and ensure compliance with global standards. Proactive grid security mitigates operational disruption, limits vulnerability exposure, and preserves national security and community trust by helping operators provide resiliency and availability.
Shield delivers a comprehensive, purpose-built cybersecurity ecosystem for grid operations that unifies asset visibility, threat intelligence, operational context, advisory insights and compliance reporting in a single operational environment.
The unified approach: aggregates and visualizes OT/ICS asset, network and security activity in one actionable view; aligns cyber insights with real-time grid operations and workflows; enables coordinated action across executive management, IT cybersecurity, OT cyber-physical, engineering, utility analytics data science and compliance teams; supports immediate insider and external threat detection plus real-time cyber AI agents for human-in-the-loop response and recovery mitigation; and reduces complexity while strengthening security posture.

OT/ICS asset inventory and asset management: continuous visibility into all grid assets, so operators always know what is deployed, how it is configured, and where risks or compliance gaps exist. The solution automatically discovers OT/ICS devices, tracks configuration and lifecycle changes, and links each asset to its operational and cyber-physical context for smarter prioritization, with audit-ready reporting aligned to global cybersecurity frameworks.
Risk prioritization and compliance reporting: an OT-focused approach to identifying and ranking cyber vulnerability risks by combining detailed OT/ICS device profiles, threat intelligence, compliance requirements and operational impact. Continuous passive or active monitoring of device vulnerabilities produces real-time, audit-ready compliance reports aligned with organizational risk profiles and global regulatory frameworks; dashboards highlight risk trends, configuration drift and status.
OT zero-touch deployment (ZTD): combines the compliance requirement of secure remote access with human-in-the-loop controlled security-policy workflows to isolate a device, update firmware, test, and place it back into production — reducing the operational risk of downtime, keeping devices patched, and supporting operational excellence. OT ZTD reduces maintenance effort by allowing updates directly from the SOC while ensuring safety, accountability and traceability.
Secure remote access: identity-based connectivity to safeguard operations, maintain compliance and prepare for future grid resilience without altering the current network. The solution integrates flexibly with various network setups — on-premises, hybrid or cloud — consistently enforces security policies across every network segment, and records each user's access session through screen capture.
Grid insider threat detection: a defense tactic combining insider role analysis, OT/ICS asset inventory, and continuous network and grid-asset monitoring to detect insider threats in real time. AI-driven analytics identify voltage tampering, line anomalies and unauthorized access, pinpointing asset locations under attack. Automated classification differentiates malicious, negligent and operational incidents to minimize false positives, and cyber AI agents automatically guide the SOC in response and recovery actions.
OT/ICS network continuous monitoring: real-time, protocol-aware visibility into industrial networks that lets operators detect anomalies, configuration drift and emerging cyber-physical risks early. It inspects OT communication protocols such as ICCP, DNP3, Modbus and IEC 61850 to find deviations in commands, traffic flows and device behavior; automated asset discovery and network mapping maintain an accurate, continuously updated topology that strengthens situational awareness.
Incident response, analysis & reporting: empowers grid operators to rapidly detect, investigate and document cyber-physical incidents with end-to-end visibility. Security events are correlated with control commands, network flows and asset states to support deep forensic analysis and root-cause discovery. The solution captures raw data and generates automated, compliance-ready reports that streamline regulatory obligations and cross-team communication.
Threat modeling & incident mitigation: equips utilities with cyber-physical insight and predictive intelligence to anticipate attack paths and assess their potential operational impact. Telemetry, user behavior and process commands are correlated with modeled threat scenarios to detect evolving risks early and guide prioritized mitigation; automated playbooks provide structured, actionable response steps — from containment to configuration hardening — reducing response time and operational risk.
Incident recovery plan execution: guides utilities from disruption back to stable OT/ICS operations by combining operational context, forensic-grade visibility and automated recovery workflows. The solution maintains secure configuration backups, enables rapid rollback to trusted system states, and preserves forensic-ready evidence to support root-cause analysis and validate recovery completeness. Recovery actions are aligned with physical process impact to ensure safe, reliable restoration without unintended operational consequences.
