A cyber tabletop exercise tells you what a team believes it would do. A range tells you what it actually does. That distinction drives the case SimSpace CEO Peter Lee made to Mike Vizard on Techstrong TV for cyber ranges vs tabletop exercises as the basis of security readiness. As attacks grow more complex, discussion-based drills leave too much untested: the tooling, the handoffs, the timing, the decisions made while an incident is still ambiguous. Immersive simulation closes that gap, putting defenders inside real-world attack scenarios where they can test skills, validate defenses, and measure operational readiness instead of estimating it. Cyber range training leaves evidence, a record of how people and technology performed and where the next investment belongs.
