OT Threat Analysis

Protecting Your Critical Infrastructure from Evolving Threats

Nation-state actors, ransomware groups, and hacktivists have all demonstrated the ability and willingness to target industrial operations. Volt Typhoon, Sandworm, and ALPHV have all made OT environments a priority in recent years.

 

Our OT Threat Analysis service is focused on identifying, assessing, and mitigating threats in Operational Technology and Industrial Control System environments. 

 

We help organizations uncover hidden vulnerabilities, understand the unique risks to industrial operations, and implement practical recommendations to reduce exposure without disrupting production.

Our Approach

OT Environment Mapping & Asset Discovery

  • Conduct passive network monitoring using non-intrusive methods that are safe for sensitive OT environments.
     

  • Build a complete asset inventory covering OT devices, PLCs, HMIs, historians, engineering workstations, and remote access points, including legacy systems that may not be documented.
     

  • Identify all industrial protocols in use (Modbus, DNP3, EtherNet/IP, Profinet, OPC-UA, and others) and map data flows between OT, DMZ, and IT networks.
     

  • Review network segmentation and zone boundaries against IEC 62443 and NERC CIP standards, identifying Purdue Model violations and unexpected IT/OT connectivity.

Threat &
Vulnerability Assessment

  • Identify exploitable weaknesses specific to OT/ICS systems, including unpatched PLCs, default credentials on HMIs, insecure remote access (e.g., RDP, VPN), and vendor-maintained backdoors.
     

  • Conduct threat modeling using MITRE ATT&CK for ICS,  mapping likely adversary TTPs to your specific industrial environment, equipment, and protocols.
     

  • Assess exposure to AI-assisted threat campaigns targeting OT/ICS protocols, including automated reconnaissance and exploit tooling designed for industrial systems.
     

  • Review patch status against the constraints of OT environments where vendor approval requirements, production schedules, and safety considerations often prevent standard patching cycles, and identify compensating controls.

Risk Analysis & Business Impact Review

  • Analyze threats against operational impact (production downtime, process disruption), safety impact (physical harm, equipment damage), and financial impact (recovery costs, regulatory penalties, reputational damage).
     

  • Build a prioritized risk matrix scored by likelihood and consequence, calibrated to your specific operations,  distinguishing between risks that cause inconvenience and those that could halt production or trigger a safety event.
     

  • Evaluate risks introduced by AI-enhanced industrial systems, including AI-driven process control and predictive maintenance platforms that may create new IT/OT attack pathways.
     

  • Map findings to applicable regulatory frameworks (eg., NERC CIP, IEC 62443, NIST CSF for OT, TSA Security Directives) and identify gaps that create compliance exposure.

Reporting & Recommendations
 

  • Deliver dual-audience reporting: executive summaries that communicate OT risk in operational and financial terms for leadership, and detailed technical findings for OT and IT engineering teams.
     

  • Provide immediate containment or mitigation guidance for any critical findings discovered during the engagement, with OT-safe remediation options that maintain production continuity.
     

  • Deliver a prioritized OT security improvement roadmap with short-, medium-, and long-term actions, distinguishing between quick wins that can be achieved without production impact and improvements that require planned maintenance windows.
     

  • Include framework alignment guidance showing how findings and recommendations map to IEC 62443, NERC CIP, NIST CSF, or other applicable OT security standards relevant to your industry.

Benefits

Comprehensive Visibility

Know exactly what's running in your OT environment, including undocumented legacy assets, shadow connections to IT networks, and industrial protocols that may be invisible to your IT security tools.

Reduced Risk

Prioritize what actually matters in an industrial context (e.g., threats that could halt production, trigger a safety event, or create regulatory exposure), rather than chasing every vulnerability with equal urgency.

Regulatory & Audit Readiness

Demonstrate compliance with NERC CIP, IEC 62443, TSA Pipeline Security Directives, or other applicable OT security frameworks, with documented evidence that auditors can verify.

IT/OT Collaboration

Most OT incidents are enabled by IT/OT boundary failures. TBDCyber bridges the gap between IT security teams and OT engineers, creating a shared risk language and integrated response capability that neither team can build alone.
