Strategic OT Cybersecurity Assessment

Understanding your current security posture is the critical first step. Our assessment services provide actionable insights aligned with industry standards like ISA/IEC 62443 and NIST CSF.

Comprehensive evaluation of your OT cybersecurity program against industry frameworks to identify gaps and prioritize improvements. We assess your people, processes, and technology to deliver a clear maturity score and actionable roadmap.

In-depth review of your existing OT network architecture to evaluate security controls, identify vulnerabilities, and recommend improvements. We analyze network topology, segmentation, access controls, and data flows to ensure your architecture meets security best practices.

Holistic evaluation of your entire OT cybersecurity program including governance, policies, procedures, incident response capabilities, and security awareness. We help you understand where you stand and what it takes to reach your target state.

Thorough mapping and documentation of your OT network infrastructure, including asset inventories, network diagrams, data flow maps, and communication matrices. Accurate documentation is the foundation for effective security management.

A structured, risk-based security assessment methodology based on ISA 62443-3-2 that identifies potential cyber threats to your industrial processes. We analyze consequence scenarios and determine appropriate security levels for each zone and conduit in your OT environment.

OT/ICS Security Engineering

We design and implement security architectures purpose-built for industrial environments, ensuring your defenses are robust without impacting operational availability.

Network Segmentation

Design and implement zone-based network architectures that contain threats and protect critical industrial processes from lateral movement.

Security Technology Evaluation

Vendor-neutral proof of concept evaluations to select the right security technologies for your specific OT environment and operational needs.

Security Technology Optimization

Fine-tune and optimize your existing security tools and configurations to maximize protection without impacting plant operations.

Cyber Acceptance Testing

Comprehensive Cyber FAT and Cyber SAT testing to validate that new systems and changes meet your cybersecurity requirements before going live.

Firewall Validation

Verify firewall configurations, rule sets, and segmentation policies to ensure they effectively protect your OT environment from unauthorized access.

Device Vulnerability & Obsolescence

Identify and remediate vulnerabilities in legacy and modern OT devices, with strategies for managing end-of-life equipment securely.

Ongoing OT Security Operations

Our role is to ensure your operations teams are equipped to perform their jobs — and do so in a secure way. We provide the ongoing support and expertise to keep your OT security program running at peak effectiveness.

Cybersecurity Program Governance

Establishing robust governance structures is the foundation for maintaining organizational security, safety, and reliability. We help you build and sustain effective OT cybersecurity governance programs.

01

Program Governance

Establish governance frameworks that align cybersecurity with business objectives, define roles and responsibilities, and ensure executive oversight of your OT security program.

02

TSA Pipeline Security Directives

Achieve and maintain compliance with TSA Security Directives for pipeline operators, including implementation of required cybersecurity measures and reporting procedures.

03

Regulatory Compliance

Navigate the complex landscape of OT cybersecurity regulations including NERC CIP, CFATS, and other sector-specific requirements with confidence.

04

Policy & Procedure Development

Develop comprehensive OT-specific cybersecurity policies, standards, and procedures that are practical, enforceable, and aligned with industry best practices.

Unified Namespace Cybersecurity

The Unified Namespace (UNS) is revolutionizing industrial data architecture — but without proper security, it creates a single point of compromise. We secure your UNS from broker to edge, ensuring your data-driven operations remain protected.

UNS Architecture Security Assessment

Comprehensive evaluation of your UNS topology, broker configurations, topic hierarchies, and data flows to identify security gaps and attack surfaces unique to event-driven architectures.

MQTT Broker Hardening & Access Control

Secure your MQTT brokers with TLS encryption, certificate-based authentication, fine-grained ACLs, and topic-level authorization to prevent unauthorized data access and injection attacks.

Sparkplug B Namespace Security

Design secure Sparkplug B namespace structures with proper node authentication, payload validation, and birth/death certificate management to maintain data integrity across your UNS.

IT/OT Data Flow Security & Governance

Establish secure data flow policies governing how operational data traverses between OT, IT, and cloud layers. Implement data diodes, content inspection, and schema validation at trust boundaries.

UNS Zero Trust Implementation

Apply zero trust principles to your Unified Namespace with device identity verification, micro-segmented topic access, continuous authentication, and least-privilege data subscriptions.

UNS Compliance & Monitoring

Continuous monitoring of your UNS for anomalous subscriptions, unauthorized topic access, payload manipulation, and broker health — with alerting integrated into your SOC workflows.

Artificial Intelligence for OT Cybersecurity

AI is transforming industrial cybersecurity — from autonomous threat detection to agentic workflows that accelerate incident response. We help you deploy AI safely and effectively in OT environments where uptime and safety are non-negotiable.

Agentic Workflow Development

Design and deploy AI-powered autonomous agents that handle repetitive OT security tasks — from automated vulnerability triage and patch validation to compliance evidence collection and incident enrichment.

AI-Powered Threat Detection & Response

Deploy AI models trained on industrial protocols (Modbus, DNP3, OPC UA, EtherNet/IP) to detect zero-day attacks, insider threats, and anomalous behavior that signature-based tools miss.

Machine Learning Anomaly Detection

Build behavioral baselines of your industrial processes using ML models that understand normal PLC logic execution, sensor readings, and network traffic — alerting on deviations that indicate compromise.

OT Security Copilot & Automation

Augment your security team with AI copilots that provide real-time guidance during incidents, automate alert correlation across IT/OT boundaries, and generate actionable intelligence from OT telemetry.

AI Governance for Industrial Environments

Establish governance frameworks for responsible AI deployment in OT — including model validation, bias testing, explainability requirements, and safety guardrails to prevent AI-induced process disruptions.

Predictive Vulnerability Management

Use AI to prioritize OT vulnerabilities based on asset criticality, exploitability in your specific environment, and potential operational impact — moving beyond CVSS scores to context-aware risk ranking.
