Your incident response plan looks good on paper but who actually runs it at 3am?

An incident response plan is essential. It sets expectations, supports compliance, and provides a framework for how a security incident should be handled. Most plans include a clear process for identification, containment, eradication and recovery. They describe communication steps, escalation paths and data protection considerations.

However, many plans are designed for audits rather than real scenarios. They assume availability of key people, perfect information and calm decision making. In reality, when an incident occurs, pressure is high, information is incomplete and response time matters. Most organisations discover this gap only when they are already on the back foot.

When a real incident occurs

A real incident does not arrive neatly packaged. Alerts trigger simultaneously. Technical teams scramble to identify what has happened. Is it a data breach, an insider threat, a payment systems issue, or a wider cyber incident affecting customer data.

In a widely publicised example, the WannaCry ransomware attack on the NHS exposed significant weaknesses in incident response processes across multiple organisations. While response plans existed, roles were not clearly defined in practice and coordination between teams proved difficult under pressure. Communication delays and inconsistent decision making increased response and recovery time. The root cause was not just the malware itself, but response processes that had not been tested against real scenarios at scale.

This is not an isolated event. Many organisations face similar challenges, even with an IR plan in place.

Why most plans fail under pressure

Most plans fail not because they are poorly written, but because they are not built for reality.

Common issues include unclear roles, where multiple people assume someone else is responsible. Finger pointing replaces decisive action. The comms lead is unsure when to engage. Internal processes conflict with the response process. Risk assessment decisions are delayed. Reputational risk grows while teams debate next steps.

Many plans do not account for insider threats, similar attacks seen in other environments, or the need for continuous monitoring during an active incident. They focus on tools and documents rather than people and decision making.

An effective incident response plan must work under pressure, not just on paper.

The importance of clearly defined roles

Effective incident response depends on clearly defined roles. When a security incident occurs, there must be no ambiguity.

• Who leads the response
• Who owns communication
• Who makes containment decisions
• Who engages customers and regulators

Defined roles reduce hesitation, prevent duplication of effort and support a clear process. They allow technical teams to focus on systems and data, while business leaders focus on impact, compliance and recovery.

Without clear roles, even experienced teams struggle.

Internal teams cannot do everything alone

Internal teams bring critical business knowledge. They understand internal systems, internal processes and the environment they operate in. This context is essential during a cyber incident.

However, many organisations focus their security efforts on prevention and day to day operations. When an incident hits, the same team is expected to respond, investigate, communicate and recover, often outside normal working hours.

Experience responding to real incidents has shown that response quality declines when teams are stretched. Fatigue, lack of recent incident experience and limited exposure to similar attacks all affect decision making.

This is where an external incident response team can act as an extension of the internal team.

Building an effective response capability

An effective incident response capability combines planning, people and practice.

It includes the following elements:

• A clear incident response plan that reflects real threat scenarios
• Clearly defined roles across security, business and communication
• Continuous monitoring to identify incidents early
• Regular tabletop exercises to test how the plan works in practice
• Lessons learned reviews to improve the response process after each event

Tabletop exercises are particularly valuable. They expose gaps in communication, unclear ownership and unrealistic assumptions before a real incident occurs. They help teams build confidence in the plan and in each other.

Why experience matters in incident response

Responding to a cyber incident is not theoretical. It requires calm leadership, rapid analysis and confident decision making.

Teams that handle incidents regularly recognise patterns, identify root cause faster and reduce recovery time. They understand how attackers move through systems, how data is exfiltrated and how to contain threats without causing unnecessary disruption to the business.

This experience cannot be learned from a document alone.

From plan to effective incident response

An incident response plan is a starting point, not a guarantee. Effective incident response comes from testing the plan, refining the process and ensuring the right people are available when it matters most.

Most organisations will face a security incident at some point. The difference between those that recover quickly and those that suffer lasting damage is not whether they had a plan, but whether that plan worked in reality.

When the incident hits at 3am, the question is simple. Does your response rely on a document, or on a team that knows how to act.
