Mission-Critical OT Capabilities

End-to-end OT security services from assessment and architecture through deployment, monitoring, and incident response

Purdue Model Segmentation

Design and implement zone and conduit architecture per IEC 62443 and ISA/IEC 62443-3-3. Deploy industrial firewalls, data diodes, and unidirectional gateways to enforce least-privilege OT traffic flows.

Continuous Threat Detection

Deploy passive monitoring sensors with ICS-specific behavioral baselines. Correlate OT anomalies with IT SIEM platforms including Splunk, Microsoft Sentinel, and IBM QRadar for unified incident response.

OT Asset Discovery & CMDB

Maintain a living inventory of PLCs, RTUs, HMIs, engineering workstations, and network devices. Map communication paths, firmware versions, and CVE exposure across the entire OT attack surface.

Secure Remote Access

Replace VPN-based vendor access with zero-trust jump servers, session recording, and just-in-time privileged access. Enforce multi-factor authentication and time-bound credentials for third-party OT maintenance.

IEC 62443 Compliance

Conduct gap assessments against IEC 62443-2-1, 3-3, and 4-1 security levels. Develop security policies, patch management programs, and security lifecycle documentation for regulated industries.

OT Incident Response

Establish OT-specific IR playbooks with forensic preservation of controller logic, network captures, and HMI state. Coordinate containment strategies that protect safety systems while minimizing production downtime.

Harden Your Industrial Environment

Partner with OT security specialists to assess risk, implement IEC 62443-aligned controls, and deploy continuous monitoring with Claroty, Dragos, and Nozomi Networks — protecting production uptime while closing the OT security gap.
