Securing OT Access with Identity and Visibility
Kroll
Overview
Operational Technology (OT) systems face unique identity and access challenges. They rely on systems such as SCADA (Supervisory Control and Data Acquisition), ICS (Industrial Control Systems), and IIoT (Industrial Internet of Things), all of which must run continuously, making standard IT security tools ineffective. Without clear visibility into who is doing what, there’s a higher risk of unauthorized access and system disruptions. Because these environments cannot tolerate system downtime, any security solution must operate in a non-intrusive, agentless manner that does not disrupt critical operations.
To address these challenges, Kroll’s offering combines Saviynt’s identity platform with Nozomi Networks’ OT security tools. This powerful combination gives organizations real-time visibility into who is accessing OT systems and how. By merging Saviynt’s identity intelligence with Nozomi’s threat detection, teams can quickly spot risks and take action strengthening access governance and reducing operational threats across critical infrastructure.
Customer Value
This solution delivers significant value by providing a holistic and centralized view of OT users, devices, and security events, enabling organizations to gain foundational visibility across complex OT environments. By enriching OT security alerts with identity context such as user role, department and location ,the solution reduces alert noise and improves the accuracy of risk assessment. Customers benefit from faster incident response, improved governance and strengthened compliance and audit readiness, all while maintaining strict uptime requirements. The agentless, non-intrusive approach ensures that critical ICS, SCADA, and OT systems remain fully operational, reducing downtime risk and improving overall operational resilience and ROI.
The solution supports real-world OT security use cases where organizations need to monitor user activity, detect suspicious behavior, and remediate access risks without disrupting operations. By combining Saviynt’s identity governance platform with Nozomi Networks’ OT visibility and threat detection, security teams can ingest OT device and user data, monitor activity, synchronize alerts, and take informed remediation actions such as accepting risk or revoking access. This approach has been successfully aligned with industry frameworks such as IEC 62443, NIST SP 800-82, and Zero Trust principles, demonstrating its applicability for customers seeking secure, compliant, and resilient OT access management in critical infrastructure environments.
