Firewall Rule Capacity Planner accuracy and testing

This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.

Formula source

  • Rule headroom = threshold rules - current rules. Months to threshold = headroom / monthly net growth.

Test cases

Default input regression check

Generated from the checked-in default inputs and calculate function.

Inputs

  • Current Rules: 3,200
  • Platform Rule Limit: 5,000
  • Warning Threshold: 80%
  • Rules Added Monthly: 180
  • Rules Removed Monthly: 60

Expected outputs

  • Months to Threshold: 6.67 months
  • Rule Headroom: 800
  • Threshold Rule Count: 4,000
  • Net Monthly Growth: 120

Known limitations

  • This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
  • Use the result as a planning estimate unless the calculator page states a stricter purpose.

Assumptions

  • Inputs are user-entered because pricing, deadlines, policies, and technical limits vary.
  • Calculations run locally in your browser and do not store passwords, incidents, network designs, or security program data.
  • This is planning math, not security assurance, legal advice, or a substitute for testing.

Unit handling

  • Current Rules accepts numeric values.
  • Platform Rule Limit accepts numeric values.
  • Warning Threshold accepts values in %.
  • Rules Added Monthly accepts numeric values.
  • Rules Removed Monthly accepts numeric values.
  • Months to Threshold is displayed in months.

Rounding rules

  • Number displays use up to 2 decimal places in the calculator UI.
  • Input precision follows configured step values where provided.
