The DIG Platform: Digital Intelligence for OT Cybersecurity

One of the most persistent challenges in OT cybersecurity is the lack of unified visibility. Industrial environments are complex, heterogeneous, and often poorly documented. Assets span multiple vendors, protocols, and generations of technology — and the security teams responsible for protecting them frequently lack the tools to see what they are actually defending.

The DIG Platform — Digital Intelligence & Governance — addresses this challenge by providing OT organizations with a purpose-built capability for asset discovery, risk intelligence, and compliance management across industrial environments.

DIG is not an IT security tool adapted for OT. It is designed from the ground up to operate within the constraints and requirements of industrial environments — passive, non-intrusive, and operationally aware.

The Core Problem: You Cannot Secure What You Cannot See

Asset visibility is the foundation of every OT security capability. Without an accurate, up-to-date inventory of OT assets — including their firmware versions, communication relationships, and operational roles — security teams are operating blind.

Traditional IT asset management tools are not designed for OT environments. They rely on active scanning techniques that can disrupt industrial protocols, cause unexpected behavior in legacy devices, or trigger safety system responses.

The DIG Platform uses passive network monitoring and protocol-aware discovery to build a comprehensive asset inventory without touching the devices it discovers — preserving operational integrity while delivering the visibility that security teams need.

• Passive asset discovery across Purdue Model levels 0–3
• Protocol-aware parsing for Modbus, DNP3, EtherNet/IP, PROFINET, and more
• Automatic classification of assets by function, vendor, and operational role
• Communication baseline mapping for anomaly detection
• Firmware and version tracking for vulnerability correlation

Risk Intelligence: From Inventory to Prioritized Action

Asset visibility alone is not enough. The DIG Platform transforms raw asset data into actionable risk intelligence by correlating asset attributes with known vulnerabilities, threat intelligence, and consequence models.

For each asset in the inventory, DIG calculates a risk score based on:

• Known CVEs and vendor advisories applicable to the asset's firmware and software versions
• Network exposure — whether the asset communicates with higher-trust zones or external networks
• Operational criticality — the asset's role in the industrial process and the consequence of its compromise
• Compensating controls — existing security measures that reduce exploitability or impact
• Threat intelligence — active campaigns or TTPs targeting similar asset types or sectors

The result is a prioritized risk register that tells security teams not just what is vulnerable, but what to fix first — based on operational impact, not just CVSS scores.

Governance and Compliance Management

The DIG Platform includes a governance module that maps the asset inventory and risk posture against applicable regulatory frameworks and internal security policies.

Supported frameworks include:

• IEC 62443 — Zone and conduit compliance, security level assessment, and countermeasure tracking
• NIST SP 800-82 — Control mapping and gap analysis for industrial control system security
• NERC CIP — Asset categorization, evidence collection, and compliance reporting for energy sector operators
• EU NIS2 Directive — Risk management and incident reporting requirements for critical infrastructure operators
• Custom policy frameworks — Organizations can define internal security baselines and track compliance against them

Compliance reporting is generated automatically from the asset inventory and risk data — eliminating the manual effort of evidence collection and reducing the risk of audit findings caused by documentation gaps.

Integration with OT Security Operations

The DIG Platform is designed to integrate with the broader OT security operations ecosystem — not to replace it.

Key integrations include:

• OT SIEM — Asset context and risk scores are forwarded to the SIEM to enrich alert triage and reduce false positives
• Incident Response — Asset inventory and communication baselines provide the context needed for rapid incident scoping and containment
• Patch Management — Vulnerability data drives prioritized patching workflows aligned with operational maintenance windows
• Change Management — Asset changes detected by DIG trigger automated change review workflows
• Threat Intelligence Platforms — DIG ingests external threat feeds and correlates them against the local asset inventory

By providing a single source of truth for OT asset data, DIG eliminates the fragmented, siloed visibility that characterizes most industrial security programs today.

Intelligence-Driven OT Security

The DIG Platform represents a shift from reactive, perimeter-focused OT security to intelligence-driven, asset-centric security operations.

When security teams have accurate visibility into what they are protecting, understand the risk associated with each asset, and can demonstrate compliance with applicable frameworks — they are in a fundamentally stronger position to defend industrial environments against the threats that matter.

At The Realm of OT Cyber, we believe that effective OT security starts with intelligence — knowing your assets, understanding your risk, and having the governance structures to act on that knowledge with confidence and precision.
