A Cyber Wargame is an exercise in which the technical defense team faces a simulated attack in real time, in a controlled environment, to practice detection, containment, recovery, and coordination between teams. It is a rehearsal for incident day, with time pressure and incomplete information.
An incident response plan that has never been executed under pressure remains a hypothesis. A Wargame reveals who stalls, which access is missing, and which steps take longer than expected.
How a Wargame differs from other exercises
A Red Team assesses, without notice, whether defenses detect and respond to an attack in production. A Purple Team brings attackers and defenders together to check whether each technique is detected and adjust rules. A tabletop exercise brings executives into a room to test decisions and communication.
Cyber Wargame trains the technical team, which knows it is an exercise, to contain and recover. Wargames and tabletop exercises complement each other: one tests execution and the other decision-making, as shown in the article on tabletop exercise.
How a Cyber Wargame works
The exercise begins by defining a scenario based on the company's greatest threats: ransomware, a data breach, a privileged account compromise, or the outage of a critical service. The scenario should come from the risk analysis and continuity plan. Preparation defines dates, participants, the systems involved, and what may or may not be touched.
During execution, the attack progresses in stages. Each stage brings new information, such as an alert, a system outage, or a user call, and the team responds while specialists facilitate and observe. This is followed by a review of what worked and what stalled, and updates to playbooks, recovery plans, and escalation workflows.
What the Wargame measures
Key measurement points:
- Time to awareness: when the first signal was noticed and when someone acted.
- Time to containment: how far the scenario progressed before containment.
- Playbooks: whether they were followed and whether they worked when followed.
- Activation: whether the right teams were called in the right order.
- Communication: whether IT, security, the SOC, and suppliers used channels that would remain operational during a real attack.
In the 2026 Cyber Risk Landscape, a Vultus study of 132 organizations, average maturity in the detect function was 1.82 on a scale of 0 to 5, and only 23% of companies had structured business continuity.
The M-Trends 2026, from Google Cloud, shows the size of the window: in 2025, initial access was handed to a second group in a median of 22 seconds, and attackers began deleting cloud backups to hinder recovery.
Frequency and participants
The exercise should take place at least annually and whenever the response plan changes or significant team changes occur. The outsourced SOC should participate, because many failures appear at the boundary between teams from different companies. A controlled environment and agreed limits prevent operational impact.
