Pieces of the Puzzle – The Power of Interconnected Cyber Drills

A crisis doesn’t respect boundaries – it unfolds in real time, demanding responses from every level, from technical teams to executives.

That’s exactly what we set out to simulate with our recent cyber drill, “Pieces of the Puzzle”, a high-intensity exercise that pushed over 300 team members into the deep end of crisis response. What set this drill apart was its interconnectivity – no single person had the full picture, and every decision mattered.

A crisis unfolds in pieces

The exercise was built around two fictional companies:

• FusionArc – A cloud-based IT infrastructure provider suffering a cyberattack
• Orchid Logistics – A global supply chain company, FusionArc’s largest customer, facing operational chaos due to the breach.

Day one simulated a cyberattack on FusionArc Solutions, with participants acting as the incident response team investigating and responding to a breach of critical systems and sensitive data.

This day showcased Immersive’s cyber range capabilities and the importance of continuous upskilling. It allowed participants to practice incident response protocols and sharpen their ability to detect, analyze, and respond to cyber threats. Live technical demos showcase real-time analysis and response, bringing the simulation to life and highlighting the skills needed to combat cyberattacks.

Day two shifted the perspective to Orchid Logistics, whose global operations across four major regions were thrown into turmoil due to the cascading impact of the attack.

Each region had its own challenges, from disrupted healthcare supply chains in Europe to financial uncertainty in North America. Different teams’ operations, legal, communications, finance, and crisis management were forced to make critical decisions with incomplete and often conflicting information.

This wasn’t just about testing individual teams. It was about stress-testing the connections between them because, in a crisis, decisions have consequences. Every action (or inaction) ripples outward, shaping how an incident unfolds and determining the effectiveness of the response.

The design: controlled chaos with a purpose

Running a cyber drill at this scale required intricate planning. Each element was carefully orchestrated to simulate the real-life confusion of a crisis where information is fragmented, priorities clash, and leaders must make tough choices under pressure.

Key elements included:

1. Dynamic information flow – Teams received updates in real-time, with technical teams feeding insights to crisis managers, who in turn had to make strategic decisions for the business.
   
   
2. Regional decision-making – Each region had its own crisis management team (CMT), responsible for navigating localized challenges while staying aligned with global headquarters.
   
   
3. Cross-functional dependencies – Operations, legal, finance, and public relations all faced their own unique crises relating to the cyberattack, as well as other unrelated business continuity disruptions. Their ability to coordinate responses mirrored the true complexity of a global business disruption.
   
   
4. Escalating pressure – Timed injects (new crisis updates), roaming media roleplayers, and breaking news images forced participants to adapt rapidly, just as they would in a real cyber event.
   
   

By layering these complexities, the exercise tested technical incident response and the entire organization’s ability to work as a single unit under duress. We looked at disaster recovery, crisis management, and business continuity all in the same cyber drill.

The power of perspective (or lack of it)

A key takeaway from the drill was how overwhelming it felt. No one had the full picture – teams made decisions with only their slice of the crisis, just like in the real world. We saw participants grappling with conflicting information, wondering why other teams weren’t responding as expected. Some felt completely isolated until they realized that the missing information was sitting with another team in another region, experiencing a completely different part of the crisis.

This is why interconnected drills are vital. They teach organizations to connect the dots and reinforce a crucial lesson: in high-stakes environments, every decision shapes the crisis’s trajectory.

Prove and improve: the true value of cyber drills

Cyber drills aren’t just theoretical exercises. They test response plans, communication, and decision-making under pressure while revealing areas for improvement. 

This drill pushed participants to work under stress and exposed gaps not just in technical response, but in collaboration, escalation, and decision-making. 

These exercises matter because they don’t just reveal weaknesses – they build resilience before a real crisis strikes.

What this means for your organization

Cyber threats affect entire businesses – customers, partners, supply chains, and finances. The biggest risk isn’t the attack itself but poor coordination in the response.

That’s why cross-team exercises are vital: technical teams must know how and when to escalate, crisis managers must grasp the stakes, and executives must make quick decisions with limited information.

Cyber drills don’t always have to be this large, but they must be realistic. Even smaller exercises focused on decision-making across teams can expose gaps in communication and preparedness before a real crisis does.

Final thoughts: crisis readiness is built, not assumed

In the debrief of Pieces of the Puzzle, one theme emerged repeatedly: we are only as strong as our connections.

The most prepared organizations aren’t just those with the best tools or plans – they’re the ones who practice together and strengthen the human elements.

Cyber drills push teams to break silos, act under pressure, and manage uncertainty. If you’re not running them regularly, the question isn’t if you’ll struggle in a crisis – it’s when.

No matter your industry, scale, or risk landscape, the key takeaway is this: crisis preparedness isn’t just about reacting – it’s about ensuring every piece of the puzzle fits before the crisis hits. 

Are your teams ready to prove and improve?
