TableTop Simulation Exercises
Got an incident response plan in a drawer? Test it before a real attack happens. We simulate ransomware, data breach, DDoS - you identify procedure gaps and train your team. NIS2 requires such exercises.

What are TableTop Simulation Exercises?
TableTop Simulation Exercises are facilitated 3–4 hour workshops where your IT, OT, management, PR, and legal teams work through realistic incident scenarios — ransomware, data breach, DDoS — without touching any production systems. nFlo designs scenarios tailored to your company's architecture, observes team decisions and communication, then delivers a detailed report with gap findings and a prioritized remediation plan, fulfilling the NIS2 requirement for regular incident response plan testing.

Maersk - Had IR Plan but Didn’t Test It. Ransomware = 10 Days Downtime
In 2017, NotPetya stopped global logistics giant Maersk. They had an incident response plan. Problem? They never tested it. During the real attack, chaos lasted 10 days - no one knew who should do what, how to communicate with customers, whether to pay ransom. Losses: $300 million.
Without testing IR plans:
- Plan in drawer isn’t the same as prepared team
- During stress (real incident) people don’t know what to do
- Communication chaos - IT vs management vs PR vs legal
- Procedure gaps emerge only during attack (too late)
- Ad-hoc decisions instead of proven process
- Non-compliance with NIS2 (plan testing requirement)
Incident Simulation with Your Team at the Table
TableTop Exercise is a workshop - team sits at a table (hence the name), we present incident scenario in stages, team discusses and makes decisions. No code, no servers - this is planning and communication exercise.
What you get:
- Incident scenario tailored to your company (ransomware, data breach, DDoS, sabotage, etc.)
- 2-4h workshop with your team (IT, OT, management, PR, legal)
- Facilitation - we lead exercise, ask questions, observe
- Staged simulation - incident escalates, team responds
- Procedure testing - do they work in practice?
- Communication testing - who reports to whom, who makes decisions
- Gap identification - what’s missing in the plan
- Report with observations and recommendations
- Remediation action plan
Who Is It For?
This service is for you if:
- You have incident response plan but never tested it
- You want to meet NIS2 (regular IR exercise requirement)
- Team or procedures changed - you want to check if they work
- You went through transformation (cloud, OT+IT) - new architecture = new risks
- You see attacks in industry and want to be prepared
Typical Scenarios
Ransomware
Phase 1: Detection
- “Monday 7:00 AM - monitoring reports file encryption on file server”
- Questions: Who gets alert? How fast do they escalate? Who makes decisions?
Phase 2: Scope Assessment
- “Ransomware spreading - 50 workstations encrypted”
- Questions: Do we cut network? How do we communicate with employees? Who informs management?
Phase 3: Containment
- “IT wants to shut down entire network. Production protests - downtime is €120K/day”
- Questions: Who has final say? Is OT safe? How do we protect backup?
Phase 4: Ransom Demand
- “Attackers demand €2 million in Bitcoin. You have 48h.”
- Questions: Do we pay? Who decides? Do we report to police? How do we communicate with customers?
Phase 5: Recovery
- “Backup works but recovery will take 72h”
- Questions: What to restore first? How to verify ransomware doesn’t return?
Phase 6: Post-incident
- “Media asking about incident. Regulator requires reporting”
- Questions: What to say publicly? How to report to regulator?
Data Breach
Scenario: Customer personal data leak
- Stage 1: Database anomaly detection
- Stage 2: Leak confirmation (100K records with PII)
- Stage 3: Reporting obligation (72h to regulator)
- Stage 4: Customer communication
- Stage 5: Forensics and root cause
DDoS Attack
Scenario: DDoS attack on online infrastructure
- Stage 1: Website/API not responding
- Stage 2: DDoS confirmation (volumetric attack)
- Stage 3: Mitigation (Cloudflare? DNS change?)
- Stage 4: Communication decision (tell customers?)
- Stage 5: Recovery and post-mortem
Insider Threat
Scenario: Fired admin sabotages systems
- Stage 1: Production change detection (deleted backups)
- Stage 2: Perpetrator identification (former employee?)
- Stage 3: Legal notification
- Stage 4: Recovery and access audit
Supply Chain Attack
Scenario: Software vendor got hacked
- Stage 1: Compromised vendor information
- Stage 2: Risk assessment (do we use that software?)
- Stage 3: Systems isolation with vendor software
- Stage 4: Patching and monitoring

What We Assess
Observation Criteria
Communication:
- Does everyone know who reports to whom?
- Is there clear command structure?
- Does information reach right people?
- Is external communication consistent?
Procedures:
- Does team know IR plan?
- Are procedures current and complete?
- Are roles clearly defined?
- Are there process gaps?
Decisions:
- Who makes key decisions?
- Are decisions fast vs thoughtful?
- Is business impact considered?
- Are legal/compliance included?
Technical:
- Does IT team know how to isolate incident?
- Are backups available and tested?
- Is forensics possible?
- Is monitoring sufficient for detection?
Culture:
- Does team collaborate vs blame?
- Are there IT vs OT vs business conflicts?
- Is it blame culture vs learn culture?

Common questions about TableTop Simulation Exercises.
How long does a TableTop exercise take and who should participate?
A standard exercise takes 3-4 hours. Participants should include: the IT/security team, management representatives, the communications/PR department, and the legal department. The optimal group size is 8-15 people.
Does the exercise affect production systems?
No. A TableTop is a discussion-based workshop - the team sits at a table and discusses an incident scenario. We don't touch any systems, we don't run any code. It is a planning and communication exercise, not a technical test.
What incident scenarios do you offer?
We design scenarios tailored to your company: ransomware, data breach, DDoS, insider threat, supply chain attack. The scenario takes into account your industry, IT architecture and real threats.
What do we receive after the exercise is completed?
The report contains: an executive summary (2-3 pages), detailed observations from each phase (10-15 pages), recommendations with prioritization (5-7 pages) and an action plan with owners and timeline. We deliver it within 5 business days.
Do TableTop exercises meet NIS2 requirements?
Yes. NIS2 requires regular testing of incident response plans. TableTop exercises are a recognized method of meeting this requirement. After the exercise, we provide documentation confirming the test was conducted.
