UK’s New Cyber Severity Scale

The UK’s Cyber Monitoring Centre (CMC) has now started categorising cyber events using a scale designed to assess the impact and severity of attacks (similar to the Richter scale for earthquakes).

What is the Cyber Monitoring Centre?

The Cyber Monitoring Centre (CMC) is an independent, non-profit organisation founded by the UK’s insurance industry to enhance trust in cyber insurance markets and improve national understanding of digital threats. Officially unveiled at a Royal United Services Institute (RUSI) event on 6 February 2025, the CMC has been operating behind the scenes for a year, refining its methodology before making its system publicly available.
