    If you have never rehearsed a Cyber Crisis, you do not have a Plan. You have a PDF.

    Most incident response plans are designed to satisfy auditors, not to function at 02:00 am when everything is burning. Attackers rehearse, regulators start the clock, executives improvise. If you have not tested your crisis response, you do not control the risk, you only document it.

    A cyber incident is rarely a technical problem for long. Within minutes, it becomes a leadership problem: stop operations or keep running, isolate networks or preserve continuity, notify or investigate, speak or stay silent. In that moment, the organisation does not rise to the level of its policies. It falls to the level of its practice.

    NIS 2 and DORA make this brutally clear. They do not reward good intentions. They expect governance, speed, evidence, and repeatable execution. If your response is improvised, your exposure is not only operational and reputational. It is regulatory and personal.

    The uncomfortable truth

    Most organisations believe they are ready because they have:

    • an incident response document

    • a crisis committee on paper

    • an IT team that “knows what to do”

    That confidence collapses in the first 60 minutes, when:

    • nobody is sure who can shut down a plant, cut a supplier connection, or pull the plug on remote access

    • legal, communications, operations and IT argue with different priorities

    • executives ask for a clear situation report and receive fragments

    What Board members and executives must demand

    You need four things, and none of them are optional:

    1. Decision rights, in writing, rehearsed

    2. A single executive situation report

    3. A notification and evidence workflow

    4. Proven recovery capability

    The key action plan (simple, non-negotiable)

    Adopt these actions at the leadership level:

    • Run a Board-level tabletop at least once per year focused on executive decisions (shutdown, public statement, regulator notification posture, supplier failure, ransom scenario).

    • Run a cross-functional crisis simulation at least once a year, involving Operations, Legal, Communications, HR, Finance, and key vendors, in addition to IT.

    • Measure readiness with four metrics (Time to convene the crisis, team, Time to first containment decision, Time to first regulator-ready incident summary, Time to restore critical operations against business tolerances)

    • Turn lessons into funded remediation within 30 days: playbooks, escalation, technical controls, and governance gaps.

    Why this matters now

    Attackers industrialise. Regulators formalise. Boards are expected to demonstrate oversight, not commentary. Under NIS 2 and DORA, “we were not ready” is no longer an explanation. It is a failure of governance.
