What Are Cyber Tabletop Exercises?

Cyber attack tabletop exercises are simulated scenario-based exercises designed to test your organisational response to cyber incidents. These exercises help evaluate the effectiveness of your incident management. They test the readiness of key stakeholders to respond to real cybersecurity events. Participants, including executives and IT teams, engage in a role-playing exercise to navigate a hypothetical cyber threat.

An expert external facilitator will recreate a Cyber Attack Scenario curated specifically for your organisation. It won’t disrupt your business operations in the least. However, the scenario will be realistic enough to make your team stand up and take note of how damaging such an attack could be to your business. 

They will think and act as they would in an actual security breach. This will brush up their familiarity with the Incident Response plans and strategies. It will enhance their cybersecurity decision-making. They’ll be able to better understand their individual roles and responsibilities in an actual cybersecurity event.

• Improve Decision-Making Skills: Provide a safe environment for leadership and response teams to practice making critical decisions under pressure.​
  
  
• Promote Cross-Departmental Collaboration: Foster teamwork among various departments, ensuring a unified approach to incident management.​
  
  
• Support Regulatory Compliance: Demonstrate due diligence and adherence to industry regulations and standards through documented testing of response plans.​

How to Conduct a Successful Cyber Tabletop Exercise? 

Effective planning is the cornerstone of a successful cyber attack tabletop exercise. We always recommend bringing an external expert on board to conduct your cyber drill. Their nuanced outsider’s perspective remains uncoloured by organisational hierarchies and politics.

They bring a cross-industry global perspective to your cyber tabletop exercise. Such insights will always be unmatched by anything available in-house. 

However, if at the moment, you’re looking to get started with your own internal cyber drill, here’s a step-by-step cyber drill guide to maximise results: 

• Define Objectives: Clearly outline what you aim to achieve with the exercise. This could range from testing specific cyber incident response protocols to enhancing team coordination.
  
  
• Assemble the Team: Gather a diverse group of participants, including executives, IT staff, and incident response team members. Ut also remember to include reps from HR, PR and the management teams. These roles have a crucial part to play in the actual response to a cybersecurity event. Ensure that everyone understands their roles and responsibilities fully.
  
  
• Create Scenarios: Develop realistic and relevant scenarios that reflect potential threats to your organisation. Collaborate with a cybersecurity expert if needed.
  
  
• Conduct the Exercise: Facilitate the exercise, guiding participants through the scenario and encouraging them to make decisions as they would in a real incident.
  
  
• Debrief and Analyse: After the exercise, conduct a debriefing session to discuss what worked well and what needs improvement. Document the findings in an executive summary.
  
  
• Implement Improvements: Use the insights gained from the exercise to refine your incident response plan and improve your overall cyber security posture.

Top Cyber Tabletop Exercise Scenarios for 2025

To genuinely strengthen your defences, it’s essential to rehearse relevant and bespoke scenarios that are carefully curated to reflect your business's unique environment, risks, and operational dependencies.

Tailored simulations allow your incident response team to practice decision-making and response strategies against the specific threats most likely to impact you. Below are some of the top cyber tabletop exercise scenarios our clients often prioritise. We adapt these to suit their individual needs:

1. Ransomware Attack

Rehearse a scenario where your organisation's critical systems suddenly become encrypted. Essential data is encrypted and operations are brought to a halt. In this cyber drill scenario, a ransom demand is promptly received, threatening further consequences if the payment is not made.

This exercise is designed to rigorously test your organisation's ability to swiftly detect such an attack and effectively initiate incident response protocols. Your team will have the opportunity to practice critical skills, such as communicating efficiently with internal and external stakeholders, including customers, partners, and possibly law enforcement.

Additionally, the team will engage in strategic discussions to evaluate the pros and cons of entering into ransom negotiations. They will be compelled to explore alternative recovery methods, such as data restoration from backups or employing decryption tools. 

2. Insider Threat

In this cyber attack scenario, a trusted employee, who has access to sensitive company information, deliberately leaks confidential data or compromises critical systems. This situation is designed to rigorously assess your internal monitoring capabilities, ensuring that any unusual activities are promptly detected. It also evaluates the robustness of access controls, determining whether they are stringent enough to prevent unauthorised access or misuse of information.

By simulating such an event, you'll uncover potential vulnerabilities in your security framework. You can then develop strategies to enhance your response to insider threats effectively. 

3. Phishing Campaign

A cyber tabletop exercise example every business should rehearse is a phishing attack. A widespread phishing campaign targets employees across various departments. This leads to potential credential compromise.  This exercise is designed to thoroughly assess your organisation's existing email security measures, ensuring they are robust enough to detect and block phishing attempts before they reach employees' inboxes.

Additionally, it evaluates the effectiveness of employee cybersecurity training programmes. It tests how well staff can identify and report suspicious emails. This scenario not only highlights areas for improvement in technical defences but also shows you the importance of continuous education and preparedness in safeguarding against evolving cyber threats.

4. Supply Chain Compromise

This cyber attack scenario simulates an attack on a third-party vendor's systems. This leads to a significant disruption in your organisation's operations. The situation serves as a critical test of your vendor risk management processes. It evaluates how effectively you can identify and mitigate risks associated with external partners. It also examines the efficiency of your communication channels, ensuring that information flows seamlessly between your organisation and the vendor.

This cyber tabletop exercise scenario challenges your contingency planning for supply chain disruptions. It assesses your ability to maintain operational continuity and minimise impact on your business.

5. Zero-Day Exploit

Simulate an attack that exploits an unknown vulnerability in widely used software. This scenario presents a formidable challenge to your organisation's cybersecurity framework. This exercise is designed to rigorously test your team's ability to identify and respond to unusual activity that may indicate a breach.

It requires the organisation to swiftly apply patches and updates to mitigate the vulnerability, ensuring that systems are protected against potential exploitation. It also compels your team to adapt to the rapidly evolving threat landscape, enhancing their ability to anticipate and respond to new and emerging cyber threats.

Final Word

Cyber attack tabletop exercises are now essential for boosting cybersecurity defences. Global regulations, like the EU DORA, stress the importance of using these simulated exercises to test how well an organisation can handle digital disruptions.

To make the most of your cyber drill, make sure to involve key stakeholders from various departments. These include IT, legal, and communications and HR. They should be able to  collaborate in a controlled environment to address a fictional cyber attack scenario. 

The exercise will help identify gaps in existing incident response efforts. It should improve communication channels, and enhance overall preparedness for real-life attacks. By rehearsing roles and responsibilities, you can strengthen your defence strategies, ensuring quick recovery while minimising financial and reputational damage.
