Gain complete visibility into every device connected to your Operational Technology (OT) environment. Sepio helps critical infrastructure operators discover, verify, and secure OT assets, improving industrial cybersecurity, reducing cyber risk, and strengthening operational resilience through Physical Layer Visibility.
Maintaining secure and uninterrupted operations across your OT environment is increasingly challenging, especially in critical infrastructure sectors.
Traditional OT security solutions focus on network and software layers, leaving critical blind spots at the physical layer.
These gaps allow sophisticated adversaries to deploy rogue devices, network implants, and spoofing hardware that remain invisible to conventional security tools.
Without complete OT asset visibility and continuous asset discovery, organizations cannot verify device integrity, identify unmanaged devices, or detect unauthorized hardware, exposing critical infrastructure to supply chain attacks, insider threats, and hardware-based compromise.
Critical infrastructure OT environments often consist of Industrial Control Systems (ICS), SCADA systems, legacy devices, and interconnected physical assets.
This complexity creates opportunities for attackers to bypass traditional defenses by targeting the physical layer.
Common attack vectors include:
Because these threats operate below the network layer, they often remain invisible to standard cybersecurity solutions.
Many critical infrastructure environments rely on legacy OT systems that were not designed for modern connectivity or evolving cyber threats.
As organizations modernize operations and deploy Industrial IoT (IIoT) technologies, IT and OT systems become increasingly interconnected, expanding the attack surface across industrial networks. The combination of outdated technology and increased connectivity introduces risks such as:
Traditional security approaches are not designed to address these challenges, leaving physical and hardware-level vulnerabilities unprotected.
Service Continuity
Maintain operational resilience and reduce downtime across critical infrastructure.
OT Asset Protection
Detect rogue devices, unauthorized hardware, and hidden attack vectors.
Compliance and Risk Management
Support compliance initiatives including NERC CIP, IEC 62443, and NIST cybersecurity guidance.
Full OT Asset Visibility
Complete asset inventory by identifying managed, unmanaged, and shadow assets across industrial environments.
Continuous visibility enables security teams to maintain accurate asset inventories, reduce attack surface exposure, support OT risk management initiatives, and improve cyber resilience across critical infrastructure environments.
Organizations must adopt a security approach that includes:
Without these capabilities, organizations cannot accurately assess risk or respond effectively to emerging threats.
Gain full visibility into all connected devices across your OT environment.
Sepio enables organizations to identify hidden, unmanaged, and rogue assets by operating at the physical layer, where traditional tools lack visibility.
With continuous monitoring and device intelligence, you can reduce cyber risk, strengthen security posture, and protect complex critical infrastructure environments.
OT asset security refers to the protection of operational technology devices, systems, and networks that support industrial processes and critical infrastructure operations.
Complete visibility allows organizations to identify unmanaged, rogue, hidden, and unauthorized devices that may introduce cybersecurity risks.
IT security focuses on business systems and data, while OT security focuses on industrial processes, physical operations, and safety-critical systems.
Physical layer visibility identifies hardware-based threats that may remain invisible to traditional network monitoring and endpoint security tools.
