Asset Cost Estimation Tool (ACET)

NPSA has developed a bespoke tool to help security managers in the UK obtain a realistic estimate of the cost of losing a critical asset

Last Updated 15 April 2025

Estimating the cost of a security incident in an organisation, business or institution is a difficult task, that’s why NPSA has developed a bespoke tool to help security managers in the UK obtain a realistic estimate of the cost of losing a critical asset – the Asset Cost Estimation Tool (ACET). 

Requiring only three key pieces of information; annual turnover, estimated number of full-time employees and business sector, the tool can: 

  • Help you to identify your critical assets, be it people, processes, information, technology or facilities
  • Deliver an estimate of financial loss should any of these assets be affected by a security incident
  • Provide sector-specific industry standard estimates for those who do not have detailed figures
  • Quickly provide users with an estimate of their overall percentage loss, alongside a breakdown estimate for each identified asset
  • Produce user-friendly downloadable graphs and charts enabling users to visualise estimated losses, reasonable worst-case scenarios, and exposure per asset
  • Provide users with a comparison to other organisations in their selected sector where sufficient open source data is available

Estimates produced by the ACET can be used to evaluate and prioritise options, support business cases, inform investment decisions, and focus attention on actions needed to protect critical assets. 

The ACET does not store any inputted data, nor is it logged or cached. 

As NPSA continues to develop and refine this free of charge and secure tool, we encourage your feedback to [email protected].
