Cyber Insurance Recovery Time Estimator

This estimator builds a practical recovery-time estimate from the main phases of cyber incident response: detection, containment, system restoration, and business validation. A parallel-work factor recognizes that some tasks can overlap instead of occurring strictly one after another. The output can support tabletop exercises, insurance submissions, continuity planning, and comparisons between current and target recovery capability. It is a planning estimate; actual recovery can vary with incident scope, dependencies, staffing, evidence preservation, and third-party availability.

1. Estimate detection time
Enter the time from disruption or alert to confirmed incident triage.

2. Estimate containment
Include isolation, access control, and stabilization work needed before restoration.

3. Add restoration and validation
Enter technical recovery time and the time business owners need to validate service.

4. Set work overlap
Use the parallel-work share for tasks that can realistically proceed at the same time.

5. Add uncertainty
Apply a contingency allowance for dependencies, rework, or delayed decisions.

Base recovery time = Detection + Containment + Restoration + Validation Adjusted base = Base recovery time × (1 − Parallel work share) Estimated recovery time = Adjusted base × (1 + Contingency allowance)

Where:

  • Phase times: estimated hours for each recovery phase
  • Parallel work share: portion of total phase time expected to overlap
  • Contingency allowance: percentage added for uncertainty and delay

Assumptions: The overlap percentage is a simplified planning adjustment and is capped below 100% so the model cannot eliminate all recovery time.

What the result means

The result is the estimated elapsed time until technical restoration and business validation are complete.

Use scenario-specific values for ransomware, cloud outage, data compromise, or other incident types rather than one universal recovery target.

Given: 6 hours detection, 10 hours containment, 24 hours restoration, 8 hours validation, 20% parallel work, and 15% contingency.

Calculation: Sequential total = 6 + 10 + 24 + 8 = 48 hours. Overlap savings = 48 × 20% = 9.6 hours. Adjusted base = 38.4 hours. Contingency = 38.4 × 15% = 5.76 hours. Estimated recovery time = 44.16 hours.

Result: Recovery is estimated at 44.16 hours, or about 1.84 days.

Is recovery time the same as a recovery time objective?

No. This result estimates expected elapsed recovery time for a scenario. A recovery time objective is a target set by the organization.

How should I estimate parallel work?

Use a conservative percentage based on the response plan, staffing, and dependencies. Tasks that require the same people or wait on the same system should not be treated as parallel.

Should data reconstruction be included in restoration?

Yes, when reconstruction is needed to return systems and records to usable condition. Include validation separately when business owners must confirm completeness or accuracy.

Why add contingency after the overlap adjustment?

The model first estimates planned elapsed work, then applies uncertainty to that adjusted duration. This avoids giving contingency credit for hours already removed as overlap.

Can I use the estimator for several systems?

Yes, but model a defined service or dependency chain. Combining unrelated systems into one total may hide the critical path that determines actual recovery.
