Most organisations now accept that cyber incidents are inevitable. Many have invested time in writing incident response plans, defining escalation paths, and documenting technical controls. Yet far fewer have tested whether those plans work under the pressures of a live incident
This gap – between having a plan and being able to execute it – is where many organisations run into difficulty when responding to a cyber incident.
That is why tabletop simulations – or cyber fire drills, as we refer to them – are increasingly seen not as best practice, but as a core part of effective cyber governance.
What is a Cyber Fire Drill?
A cyber fire drill is a structured, scenario-based exercise designed to test how an organisation would respond to a realistic cyber incident.
Often run as a tabletop exercise, it brings together key stakeholders in a business – senior leadership, IT, legal, communications and operations – and places them into a credible scenario such as ransomware, data compromise, email takeover or critical system disruption.
The focus is not just on systems and tools, but on how decisions are made, how incidents are escalated, how teams coordinate under pressure, and how the organisation communicates internally and externally.
From Plans to Performance
Cyber fire drills do not just test documents or policies – they test how people make decisions when things start to go wrong.
Cyber incidents are rarely purely technical events. They are leadership, communication, and coordination challenges. They require rapid decisions, clear ownership, consistent messaging, and the ability to prioritise competing risks under pressure.
Without prior rehearsal, even well-run organisations struggle in these moments. Senior leaders are forced to make critical decisions with limited information. Teams fall back on assumptions about suppliers, recovery times, or responsibilities. Communications become reactive, and the organisation risks losing control of the narrative.
Fire drills allow organisations to experience these dynamics before they are real. Leadership teams practice decision-making. Roles and escalation paths become clearer. Communications are stress-tested. Recovery assumptions are challenged.
Instead of discovering weaknesses during a live incident, organisations uncover them safely – and fix them while the stakes are still hypothetical.
Most importantly, cyber fire drills build organisational muscle memory. When something does happen, teams are not starting from zero. They are responding to a situation they have already encountered.
Why Governance and Regulatory Frameworks Now Expect This
Cyber fire drills are increasingly expected, not just recommended, as part of effective cyber governance.
The UK’s government’s Cyber Governance Code of Practice, co-designed by the National Cyber Security Centre (NCSC), makes clear that boards are responsible for ensuring their organisation can respond to and recover from cyber incidents effectively. Crucially, the Code goes beyond the existence of policies and plans. It expects leadership teams to have confidence that their arrangements are operational, understood, and workable in practice.
International frameworks reinforce the same principle. ISO/IEC 27001 requires organisations to maintain an information security incident management capability as part of their overall management system, with a strong emphasis on review and continual improvement. Likewise, the NIST Cybersecurity Framework embeds incident response and recovery as core functions of cyber risk management, framing maturity around the ability to respond and recover effectively – not simply the presence of documented procedures.
Across all of these, the message is consistent: incident response is not a static policy document. It is a capability that must be tested, refreshed, and improved over time.
The Consequences of Not Testing
Organisations that do not regularly test their incident response often only discover gaps when it is too late – when attackers are already inside the environment, data has been compromised and operational systems are disrupted.
At that point, the organisation is no longer dealing with a theoretical risk, but a live crisis. Uncertainty over roles and authority can slow decision-making at the worst possible moment. Critical actions are delayed while teams work out who owns what. Communications become fragmented or inconsistent, increasing reputational risk and undermining stakeholder trust.
As the incident unfolds, assumptions about recovery, backups, and third-party support are frequently exposed. What was believed to be a contained technical issue can quickly become a wider business disruption, with operational, financial and legal consequences.
In many cases, the technical incident itself is manageable. It is the lack of preparedness, coordination, and clarity -rather than the attack alone – that turns it into a crisis.
Where Mitigo Fits In
At Mitigo, we help organisations ensure their incident response arrangements are not just documented, but operational and effective. We support leadership teams to practise response, identify gaps, and strengthen governance in line with recognised frameworks.
We do this through a tiered approach, allowing organisations to start with light-touch, scenario-based exercises and progress to more advanced simulations that introduce greater realism, pressure and operational testing.
This means teams can build confidence over time – from walking through response plans in a controlled environment, to stress-testing communication, decision-making and recovery assumptions in conditions that closely mirror real incidents.
Our focus remains on what matters most in a real event: people, decisions, communication and recovery.
The Bottom Line
Cyber fire drills are no longer a “nice to have”.
They demonstrate good cyber incident readiness and are one of the clearest indicators of whether an organisation is genuinely prepared for a serious incident.
Having a plan matters. Knowing it works matters more.
