Network Compliance Score Calculator

Score network compliance from controls implemented, findings outstanding, config drift and audit currency.

About Network Compliance Score Calculator

Control coverage carries the largest weight because it is what an auditor tests first, while configuration drift is scored separately since a control can be documented and still not be in force on 10% of devices. Critical findings cost more than major ones, and audit currency only starts costing points after twelve months. Compliance failures are usually drift failures — the design was compliant, the running config is not — and separating the two dimensions shows which one to fix.

Formula

Network Compliance Score

score = control coverage (45) + configuration conformance (25) + findings penalty (20) + audit currency (10).

control coverage
Controls fully implemented ÷ controls in scope
configuration conformance
Devices matching the golden config ÷ devices in scope

Worked example

With the default values below, Network Compliance Score Calculator returns Compliance Score of 71.3. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 7 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is Network Compliance Score calculated?

score = control coverage (45) + configuration conformance (25) + findings penalty (20) + audit currency (10). Control coverage carries the largest weight because it is what an auditor tests first, while configuration drift is scored separately since a control can be documented and still not be in force on 10% of devices. Critical findings cost more than major ones, and audit currency only starts costing points after twelve months.

Why does Network Compliance Score matter?

Compliance failures are usually drift failures — the design was compliant, the running config is not — and separating the two dimensions shows which one to fix.

What values do I need to enter?

This calculator takes 7 inputs: Controls in scope, Controls fully implemented, Critical findings open, Major findings open, Devices in scope, Devices deviating from the golden config, Months since the last audit. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
