What is a Cyber Incident Exercising?
Cyber incident exercising is the process of practising cyber response techniques against potential threats in a safe and simulated environment.
The purpose of cyber incident exercising is to prepare cyber security teams for real threat scenarios, where response time is critical.
Its tactics and techniques can be used to establish current organisational practices and formulate an incident response plan (IRP) - or to evaluate the effectiveness of an existing IRP.
The Importance of Cyber Incident Exercising
Our cyber incident exercise service is recommended for any organisation looking to upskill and optimise their cyber security team’s ability and preparedness to handle the latest threats.
In the unfortunate event of a breach, well-practised teams can communicate, respond and remediate the threat effectively to minimise the impact. Several key benefits include:
- Cross-team Coordination: Bridewell’s cyber incident exercising service incorporates multiple departments, from IT to legal and communications. During incident response situations, your teams will gain necessary insight into each role and work collaboratively.
- Realistic Scenarios: Roleplaying scenarios suggested by our cyber incident exercising team are based on threats your organisation faces, updated with current industry trends. This is done to provide a realistic environment in which to pressure test your team.
- Identify Gaps in Security: With Bridewell’s cyber incident exercising service, you’ll be able to review team performance in simulations, so you can spot and amend any gaps in team coordination.
What to Expect from Cyber Incident Exercising with Bridewell
Our cyber incident exercising service is designed to prepare your organisation for an effective response against cyber attacks.
It replicates the realistic scenarios your organisation might face. So, key staff know their roles and responsibilities when a live incident occurs. This means less time speculating and more time responding in the face of a real attack.
The key components of our cyber incident exercising service include:
Realistic Simulations
Cyber incident exercising offers tailored simulations that imitate a real cyber attack. This is based on risks, vulnerabilities, and industry threats, to make the simulation highly relevant to a specific organisation. These attacks can range from ransomware to data breaches or insider threats. The aim is to challenge your organisation’s response capabilities and pressure test your team to identify gaps in your remediation process.
Team Involvement
Bridewell’s cyber incident exercising service incorporates members from various departments, including IT, security, communications and legal. This helps ensure that everyone within your organisation is coordinated in its approach to cyber threats.
Cyber Live Play Exercises
Bridewell’s Live Play exercises emulate an adversary incident as a trigger event - adding realism that goes beyond the boardroom table. Technical Live Play is based on your organisation’s threat landscape and uses MITRE ATT&CK tactics and techniques to develop incident escalation. Executive Live Play focuses on senior decision-making, leadership response and communication in the event of a live attack.
Tactical Guidance
Bridewell’s cyber security experts provide tactical guidance in real-time, offering advice and helping teams understand best practices and improve response strategies.
Debrief and Improvement Plans
Our team of experts will provide a debrief and feedback post-simulation to help break down gaps in team performance and provide actionable plans for improvements going forward.

The Challenge
Our client is a UK-based water company that is within scope of the NIS Regulations and required by their competent authority, the Drinking Water Inspectorate (DWI), to submit a self-assessment against the National Cyber Security Centre (NCSC) Cyber Assessment Framework (CAF).
To comply with the 16 initial outcomes set out by the DWI, our client had put a cyber resilience improvement program in place to make the necessary changes. Our client was regularly tracking their position against the outcomes and were rating themselves as Fully Achieved against 8 of the 16.
The Solution
Based on our extensive experience with the CAF and the water sector, this water company chose Bridewell to validate this position. Where the company had assessed itself as ‘Fully Achieved’ against an outcome, Bridewell was to assess each individual Indicator of Good Practice (IGP) to validate the position. Where the company had assessed itself as ‘Not Achieved’ against an outcome, Bridewell was to review the proposed remediation to verify if the outcome would be ‘Fully Achieved’ once delivered.
Typically, we would perform this type of assessment by reviewing relevant documentation and interviewing key stakeholders from a range of different teams to gain full understanding of the implementation, management, and operation of cyber security measures to meet IGPs.
However, on this occasion, the client only requested assessment through interviews with the information security team. Whilst this differed from our usual approach and meant we were unable to provide any assurance over the controls in place, the approach allowed us to quickly gain adequate understanding of the state of cyber security across the 16 outcomes.
The Results
Bridewell provided a comprehensive report with the findings from the assessment, detailing:
Our assessment of attainment against each IGP for the 8 outcomes the client had rated themselves as fully achieved with full explanation and recommendations for improvement for any IGPs we believed were not being met.
Our assessment of the plans in place to meet the deficient IGPs across the 8 outcomes the client felt they were not meeting, with recommendations for additional measures that should be adopted where we felt current plans would not deliver attainment against any of the outcomes IGPs.
Executive summary detailing the approach to the assessment and the main findings.

Cyber Incident Exercising FAQs
Incident response exercising should be conducted regularly, for example annually or biannually, depending on your risk profile and requirements. It should also be undertaken when significant updates or changes are made to your cyber security infrastructure. This could be through new staff, systems or identified threats.
Tabletop exercising and live play are both cyber incident tactics designed to assess and develop an organisation’s cyber readiness. But they differ in their approach.
A tabletop exercise, as its name suggests, is based in the boardroom. It involves walking teams through potential scenarios and helping them understand their roles and responsibilities as incidents escalate. This can be valuable in building confidence and understanding in a workshop environment.
Live play goes one step further by simulating a real attack to trigger a cyber incident. The main benefit of live play is the ability to pressure-test individuals in a realistic attack scenario.
Live play and red teaming are both cyber security tactics used to test a team’s ability to effectively respond to threats.
Red teaming aims to test an organisation’s ability to detect and manage attacks by simulating an attempt to hack or compromise the IT environment. It aims to evaluate threat prevention and spot gaps in defences.
Live play is instead focused on testing the organisation’s response once an incident has already occurred. It focuses on response effectiveness – how teams communicate and ultimately remediate a live, escalating incident.
