IT-OT Security Convergence
Unified protection for converged industrial environments. Causal AI detects cyber-physical threats that traditional security tools miss — before they reach your control systems.
Air Gaps Are Gone. Traditional Security Cannot Protect Converged Environments.
For decades, industrial facilities relied on physical isolation between OT control systems and IT enterprise networks. That model collapsed under Industry 4.0. Smart sensors feed cloud analytics. ERP systems talk directly to PLCs. Remote engineers adjust reactor setpoints from another continent.
The result? Attack surfaces that traditional security architectures were never designed to defend. The global average cost of an industrial cyberattack now exceeds $4.8 million per incident, with ransomware targeting OT environments increasing 68% year-over-year.
Three OT characteristics make traditional security tools ineffective: deterministic timing (a 200ms latency spike can trip a safety interlock), legacy protocol opacity (Modbus and PROFIBUS lack native authentication), and operational context ignorance (a SIEM sees a PLC write command but cannot tell if it is safe or dangerous).
Security Through Causality. Protection Without Performance Compromise.
Tattva Twins embeds security directly into its Causal Digital Twin — the same model that predicts process deviations and prescribes optimal adjustments also serves as a real-time security validator.
By modeling cause-and-effect relationships across IT and OT domains, the platform detects anomalies that violate known causal chains. An attacker who understands the process well enough to make gradual, bounded adjustments that evade threshold alarms will still be caught when their adjustments create causally impossible state combinations.
Security becomes not an overhead cost but an intrinsic output of operational intelligence. The edge-deployed inference engine runs at process cycle speeds, validating commands locally so raw data never leaves the facility.
How Causal AI Transforms Industrial Cybersecurity
Six integrated capabilities that replace reactive security monitoring with proactive, process-aware threat defense.
Causal Anomaly Detection
Validate every control command and sensor reading against your facility causal graph. Commands that violate physical causality are flagged as potential security events regardless of network origin or credential validity.
Unified IT-OT Visibility
One causal model spans enterprise IT (ERP, MES, scheduling) and operational technology (DCS, PLC, SIS). Security analysts see the complete attack path from phishing email to process manipulation — not isolated network segments.
Sub-Second Anomaly Response
Edge-deployed causal inference runs at process cycle speeds. Security-relevant deviations trigger automated containment — parameter clamping, control transfer to safety systems, or operator alerts — within the real-time window.
Compliance-Ready Audit Trails
Every causal validation decision is logged with supporting evidence — which causal edges were checked, expected ranges, and acceptance rationale. Regulator-ready documentation for NIS2, IEC 62443, and FDA cybersecurity audits.
Zero Trust for OT
Micro-segmentation at the process cell level with identity-aware access controls. Devices and process contexts are authenticated, not just users — preventing credential compromise from automatically translating into operational disruption.
Predictive Threat Surface Analysis
Simulate how specific process manipulations cascade through the causal graph to identify which control points — if compromised — would create the largest downstream safety or financial impact.
Edge-Native Security Architecture
Causal inference runs on industrial edge gateways within the OT network. Raw process data never leaves the facility. Only aggregated insights and alerts transit to enterprise dashboards — eliminating the classic cloud security objection in OT environments.

Securing Every Industrial Domain
Causal AI security tailored to the specific process logic, control systems, and threat models of each industry.
Chemical & Pharma
Protect reactor setpoints, granule moisture controls, and batch recipe integrity. Detect manipulation that stays within numerical bounds but violates physical causality.
Steel & Cement
Monitor sinter basicity, blast furnace stability, and kiln temperature cascades. Identify control manipulation that would propagate to safety-critical process states.
Oil, Gas & Energy
Secure SCADA networks, pipeline pressure controls, and turbine governor systems. Detect anomalous setpoint changes before they cascade into safety shutdowns.
Automotive & Electronics
Protect robotic weld parameters, paint booth conditions, and semiconductor etch recipes. Catch subtle process drift that signals upstream credential compromise.
Shipbuilding & Mining
Secure shipboard control systems and autonomous mining haul fleets. Validate that remote commands are causally consistent with current operational conditions.
Food & Packaging
Protect pasteurization temperatures, fill weights, and sterilization cycles. Ensure recipe integrity across distributed production and contract packaging sites.
Regulatory-Ready Documentation, Generated Automatically
In 2026, compliance is no longer a patchwork of guidelines — it is an enforceable matrix where converged IT-OT security is board-level accountability. The Tattva Twins causal security framework generates compliance evidence as a byproduct of normal operations.
EU NIS2 Directive
Article 21 mandates risk analysis, incident handling, business continuity, and supply chain security with documented evidence. Tattva Twins generates compliance evidence as a byproduct of normal operations.
IEC 62443-3-3
Secure product development lifecycle and OT service provider requirements. The causal graph itself serves as a documented threat model with explicit node criticality and manipulation pathway mapping.
SEC Cybersecurity Disclosure
Publicly traded manufacturers must document OT security posture in financial filings. Continuous causal validation logs provide always-current security assessment data.
FDA Cybersecurity Guidance
Threat modeling and vulnerability management throughout the pharmaceutical manufacturing product lifecycle. Causal simulations demonstrate proactive risk analysis automatically.
