Cybersecurity & Trust

Securing industrial domains and creating trustworthy ecosystems

As digital industry, mobility, and smart infrastructure scale, security and trust must scale with them. Cybersecurity & Trust is a Siemens Company Core Technology — a research field that advances the foundational technologies for secure and trustworthy digital operations across Siemens' full business domain.

Cybersecurity and trust are fundamental to industrial digital transformation. As systems across manufacturing, transportation, and smart infrastructure become increasingly connected and software-defined, protecting critical infrastructure, intellectual property, and data integrity is essential. AI embedded in operational and decision-making processes adds new attack surfaces, integrity risks, and questions of accountability that security architectures must address.

Why Cybersecurity & Trust matters

Cyber threats, supply-chain complexity, and IT/OT convergence are growing alongside connectivity and data dependency across industrial, mobility, and infrastructure environments. The rapid adoption of AI introduces additional risks that security architectures must keep pace with.

Today's technology decisions shape tomorrow's resilience. They determine whether cross-ecosystem collaboration can be trusted and whether new digital business models can be adopted safely. This applies equally to a factory floor, a rail network, or a smart building.

Cybersecurity & Trust addresses the foundations of secure digital operations — so that security is engineered into systems, data flows, and platforms from the outset, not retrofitted after deployment. This includes ensuring that AI systems operating across these domains can be evaluated for security, transparency, and trustworthiness.

The technology foundation supports:

• Secure products, solutions, and production systems across industrial, mobility, and smart infrastructure environments
• Protection of critical infrastructure — including energy grids, transport networks, and building systems — through resilient, domain-appropriate security architectures
• Automation of security processes, including AI-assisted operations
• Trustworthy data exchange in open ecosystems, enabling data-driven business models across industrial operations, mobility services, and smart infrastructure platforms

These capabilities are relevant across Industrial IoT, connected mobility, smart grid and building automation, machine-to-machine communication, AI-driven automation, and globally distributed supply chains

A competitive differentiator across industrial domains

Cybersecurity and trust are not optional features — they are engineering requirements and, where implemented well, a measurable business advantage. Siemens combines deep cybersecurity expertise with industrial domain knowledge to address the security demands of operational technology (OT), information technology (IT), integrated cyber-physical systems, and AI-enabled applications across manufacturing, transportation, and smart infrastructure.

The technology portfolio spans:

• Integrity, confidentiality, and availability of systems and data — whether AI-powered or not
• Secure identities and access across distributed environments, including AI agents
• Trustworthy communication and service enablement across open ecosystems
• Federated trust models that do not depend on a single central authority
