Siemens has launched SINEC Secure Connect, a zero trust security platform designed specifically for protecting operational technology networks against modern cyber threats. The software solution virtualizes industrial network structures using overlay technology while eliminating traditional VPN vulnerabilities through granular, identity-based access controls. This comes as industrial operators face increasing pressure from both security threats and administrative complexity in converging IT and OT systems.
Zero Trust Architecture for Industrial Environments
SINEC Secure Connect implements a zero trust security model that assumes no device or user should be inherently trusted, regardless of their network location. The platform establishes end-to-end encrypted connections between authorized devices while implementing granular, policy-based controls that prevent lateral movement across industrial networks. Unlike traditional VPN approaches that create broad network access, Siemens’ solution verifies every connection attempt and enforces least-privilege access principles.
The platform’s architecture aligns with the NIST Zero Trust Architecture standards, requiring continuous verification of all access requests. “Traditional network security approaches struggle with the convergence of IT and OT systems, creating vulnerabilities when industrial systems connect to cloud services, remote access points, and external partner networks,” says Michael Metzler, Vice President of Horizontal Management Cybersecurity for Digital Industries at Siemens. This approach is particularly critical given that industrial control systems increasingly face sophisticated cyber threats targeting critical infrastructure.
Simplified Deployment and Management
SINEC Secure Connect significantly reduces administrative overhead through simplified network administration that requires only outbound connections. This eliminates the complex configuration management associated with traditional OT security solutions, which often involve maintaining numerous firewall rules and network segmentation policies. The platform’s overlay network technology virtualizes physical network structures, allowing security policies to be managed independently from underlying infrastructure.
The solution enables flexible deployment options including on-premises, cloud, and hybrid configurations, making it suitable for diverse industrial environments. Built-in redundancy ensures high availability regardless of existing infrastructure constraints, a critical requirement for industrial operations where downtime can cost millions per hour. According to IBM’s 2024 Threat Intelligence Index, manufacturing was the second-most attacked industry, facing 23% of all cyber incidents, highlighting the urgent need for simplified yet robust security solutions.
Comprehensive Connectivity and Compliance
The platform enables Machine-to-Machine, Machine-to-Cloud, and Machine-to-Datacenter connections while providing secure remote access to industrial systems without traditional VPNs. This comprehensive connectivity supports modern industrial digitalization initiatives while maintaining security posture. SINEC Secure Connect protects shop floor devices from unauthorized external access while maintaining necessary operational connectivity for production systems.
The solution enables compliance with IEC 62443 cybersecurity standards for industrial automation and control systems, which have become increasingly important for regulatory compliance and insurance requirements. Integration with Siemens’ existing SCALANCE portfolio for OT networks allows companies to reuse their current equipment investments while upgrading their security posture. This approach addresses the challenge noted in the SANS 2024 OT/ICS Cybersecurity Report that 42% of organizations struggle with integrating new security solutions into existing industrial environments.
Addressing Industrial Security Challenges
Industrial operators face mounting security challenges as connectivity increases across production systems. The convergence of IT and OT networks has expanded the attack surface while traditional security solutions often prove inadequate for industrial environments. SINEC Secure Connect specifically addresses these challenges by providing security that adapts to dynamic industrial networks rather than requiring networks to adapt to security constraints.
The platform’s ability to reduce IP-based machine management complexity while maintaining strong security controls represents a significant advancement for industrial cybersecurity. As noted in the McKinsey Cybersecurity Trends report, organizations are increasingly seeking security solutions that balance protection with operational efficiency. Siemens’ approach acknowledges that industrial security must enable business operations rather than hinder them, particularly as digital transformation accelerates across manufacturing and critical infrastructure sectors.
