Overview
OT Asset Inventory delivers a complete listing of controllers, PLCs, HMIs, sensors and other ICS devices in your network. We combine passive monitoring and active scanning—without disrupting production—to generate an accurate asset database.
A reliable inventory is the cornerstone of risk assessments, obsolescence planning and effective maintenance scheduling, ensuring operational continuity and security.
Why Build an Asset Inventory?
Security: Detect and eliminate unauthorized or unmanaged devices before attackers exploit them.
Compliance: Meet NIST SP 800-82, IEC 62443 and other regulatory requirements with documented asset records.
Efficiency: Streamline maintenance and reduce downtime with an accurate view of your hardware and firmware landscape.
Decision Support: Use verified asset data to guide capital investment and upgrade plans.
Key Benefits
- Accurate asset management and lifecycle tracking
- Reduced maintenance windows and unexpected outages
- Strengthened OT security—no unknown devices lurking
- Transparent budgeting and CAPEX planning
- Seamless regulatory and audit compliance
- Optimized resource utilization and waste reduction

Role of Asset Discovery in OT Security
Proactive asset discovery uncovers hidden or unauthorized devices across sprawling OT networks. Unlike IT environments, OT infrastructures often include legacy controllers and proprietary protocols, making discovery challenging but essential.
Methods: Network scanning via OT protocols (Modbus, DNP3), passive traffic analysis, device fingerprinting and service identification.
Benefits: Early detection of risky devices, faster incident response, and minimal production impact.
Challenges: Heterogeneous devices, legacy systems and organizational silos—but a holistic tech–process–people approach overcomes them.
