Critical Infrastructure Security

Nation-state actors are actively pre-positioning within critical infrastructure networks. We protect the operational technology environments that power, water, and connect essential services — with a non-disruptive, OT-specialist approach that understands the supremacy of operational continuity.

The OT Security Threat

Nation-State Actors Are Already Inside Critical Infrastructure Networks. Your Sector Is a Target.

The era of critical infrastructure being safe due to air-gaps and obscurity is over. The convergence of IT and OT networks over the past decade has systematically eroded the isolation that once protected industrial control systems. Nation-state actors have taken full advantage — CISA and NSA advisories document active, ongoing pre-positioning within power grids, water systems, and telecommunications infrastructure by sophisticated APT groups.

The consequence of an OT security failure is categorically different from an enterprise IT breach. A compromised SCADA system controlling power distribution or water treatment can cause physical damage to critical equipment, environmental harm, and direct threats to public safety — making OT security a matter of national importance, not just operational risk management.

OT/ICS Assessment

Non-disruptive security evaluation of your industrial control systems

SCADA Security

Protocol-aware security testing of SCADA networks and communication

OT Monitoring

Passive continuous monitoring for anomalous behaviour in OT environments

IT/OT Segmentation

Validating the controls preventing pivot from IT networks into OT systems

Our Methodology

5-Phase OT Security Engagement

A safety-first, operationally-aware methodology that delivers comprehensive OT security assessment without disrupting the critical services your infrastructure provides.

01

OT/IT Asset Discovery & Inventory

We conduct a passive-first discovery of your operational technology environment — identifying connected PLCs, RTUs, HMIs, SCADA servers, engineering workstations, and historian systems — before any active testing commences.

02

Risk Assessment & Attack Vector Analysis

We model the attack pathways that nation-state actors and sophisticated threat groups use to traverse from IT networks into OT environments — identifying the specific choke points where compromise is most likely and most damaging.

03

OT/ICS Security Assessment

A non-disruptive assessment of your Industrial Control System security — evaluating network architecture, air-gap integrity, remote access controls, vendor connectivity, and engineering workstation security against IEC 62443 and NIST SP 800-82.

04

Remediation Without Disruption

We provide a sequenced remediation plan designed to improve security without disrupting operational processes — working within planned maintenance windows and ensuring every change is reviewed by operational engineers before implementation.

05

OT Incident Response Readiness

We develop OT-specific incident response playbooks, conduct tabletop exercises with operational and security teams, and help establish the monitoring capability needed to detect anomalous behaviour in OT environments before it becomes an operational incident.

OT Security Services

Comprehensive Critical Infrastructure Security Services

From OT risk assessment to industrial threat monitoring — every service is designed for the unique operational constraints of critical infrastructure environments.

OT/ICS Security Assessment

A comprehensive, non-disruptive assessment of your Industrial Control System security posture — evaluating architecture, access controls, network segmentation, and control system integrity against IEC 62443 and NIST SP 800-82.

SCADA & Industrial Network Security

Evaluation of your SCADA network architecture, communications protocols (Modbus, DNP3, IEC 61850), and historian connectivity — identifying pathways that enable lateral movement from IT to OT environments.

OT Threat Detection & Monitoring

Designing and implementing OT-specific monitoring capability using passive network analysis tools — providing continuous visibility into anomalous behaviour in your industrial network without impacting operational performance.

IT/OT Network Segmentation Review

Assessment of the controls governing communication between IT and OT networks — validating DMZ architecture, firewall rulesets, and the jump server security that prevents threat actors from pivoting into operational systems.

Vendor & Remote Access Security

Evaluating the security of third-party vendor remote access — a primary attack vector for OT environments — and implementing controls that provide operational access while preventing lateral movement into sensitive control systems.

OT Incident Response Planning

Developing OT-specific incident response playbooks, crisis communication protocols, and regulatory notification procedures — ensuring your operational and security teams are prepared to respond effectively to a cyber incident in the OT environment.

Why Adayptus

OT Security Demands Specialists — Not IT Generalists.

Industrial environments require security practitioners who understand engineering operations, industrial protocols, and the consequences of getting it wrong. Our OT specialists bring deep technical knowledge and operational sensitivity to every engagement.

OT-First Methodology

We understand that operational continuity cannot be compromised — our assessments are designed around safety and availability requirements from the first day of engagement.

Nation-State Threat Intelligence

Access to current intelligence on nation-state threat actors and APT groups specifically targeting your sector's critical infrastructure.

ICS Protocol Expertise

Deep technical knowledge of industrial communications protocols — Modbus, DNP3, IEC 61850, Profinet, OPC — and their specific security characteristics.

Regulatory Experience

Experience delivering assessments that satisfy NCIIPC, CERT-In, IEA, and international ICS security requirements for regulated critical infrastructure operators.
