Top Exercise TTX

An OT Cyber Tabletop Exercise is a structured, scenario‑based simulation of a realistic cyber incident impacting industrial control systems (ICS), OT networks, and safety‑critical operations. The exercise evaluates the organisation’s ability to detect, respond to, and recover from cyber events that could disrupt production, affect safety, or compromise critical assets. Participants are required to think and act as they would during a real OT cyber crisis, providing clear insight into how well the organisation can manage operational and business impact.

OT Cyber Tabletop Exercises help identify vulnerabilities in OT environments and expose gaps in OT‑specific incident response plans, roles, and decision‑making processes. By engaging stakeholders from operations, engineering, OT maintenance, IT, cybersecurity, safety, and management, the exercises improve coordination, communication, and escalation during incidents affecting production or safety. Regular OT cyber tabletop exercises also support alignment with industrial cybersecurity and safety standards (such as IEC 62443, NIST) and promote a strong culture of cyber awareness across operational teams. Ultimately, these exercises strengthen OT cyber resilience, helping organisations respond effectively to evolving cyber threats while maintaining safe and reliable operations.

Our TTX are delivered from an independent, vendor-neutral perspective, each exercise provides clear, practical, and actionable insights—focusing on decision-making, governance, and business impact rather than tool-specific outcomes—so organisations can confidently prioritise improvements that genuinely reduce cyber risk.

OT Cybersecurity Table Top Exercise

Structured, scenario-driven exercises designed to test real-world incident response readiness across OT environments.

01

Tailored Purpose-Built Scenarios

Our OT Cybersecurity table-top exercises are not generic. Each scenario is tailored to your organisation, designed around your industry, technology stack, critical systems, and OT crown-jewel assets. Our custom built Table Tops are realistic threat scenarios that reflect how an incident would actually unfold in your environment — not a theoretical one — ensuring discussions are relevant, credible, and valuable.

02

Cross-Functional Participation

Real cyber incidents don’t just belong to technology teams. Our exercises bring together OT personnels, Plant/Site Manager, C-Level executives, IT, security, legal, HR, and communications teams, reflecting the decisions and pressures faced during a real event. This cross-functional approach exposes gaps in ownership, escalation paths, and decision-making that are often invisible until an incident occurs.

03

Expert-Led, Facilitated Workshops

Each session is facilitated by experienced OT cyber security consultants who actively guide the discussion, challenge assumptions, and introduce realistic injects as the scenario evolves. We test not just technical response, but leadership judgement, communication clarity, and the organisation’s ability to operate under pressure.

04

Actionable Debrief & Roadmap

Every exercise concludes with a structured debrief that translates discussion into action. You receive clear, prioritised recommendations and a practical roadmap to strengthen incident readiness — covering people, process, and technology improvements. The outcome is clarity: knowing where you stand today and exactly what to improve next.

Key Aspects of OT Penetration Testing

01

Focus on Safety and Uptime

Unlike traditional IT Penetration testing, which prioritizes data confidentiality, and is intrusive to network and systems , OT Penetration testing is carefully conducted to ensure zero disruption to production, machinery, and safety systems.

02

Scope

Covers specialized industrial equipment, legacy systems, and network protocols common in manufacturing, energy, and utility and other industrial sectors.

03

Methodology

Follows frameworks like MITRE ATT&CK for ICS ( Add link MITRE ATT&CK for ICS) to map techniques, including reconnaissance, initial access from IT networks, and exploiting control systems.

04

Deliverables

Provides a comprehensive report with risks, technical vulnerabilities, and actionable recommendations to secure the OT environment.

05

Purpose

Validates defenses and strengthens security against threats like ransomware spreading from IT to OT , Insecure Remote Access and various other threat scenarios applicable to ICS environment.
