A definitive guide for UK commercial businesses (manufacturers, retailers, hospitality operators, IT firms, professional services offices, charities and educational institutions) to the interaction between cyber insurance and conventional commercial cover — property, business interruption, crime, liability.
One hub page, eight spokes, around 28,000 words total.
If you have a live incident: open the hub page, work through the decision tree section, then read the spoke most relevant to your incident.
If you are preparing for renewal: read the hub end-to-end, then read spoke 1 (ransomware) and spoke 4 (supply chain) for any operationally dependent business; add spoke 5/6/7/8 if you operate in the named sector.
If you are a buyer thinking about programme architecture: read the hub, then read spokes 1, 2 and 4 in turn.
If you are a CFO or COO modelling exposure: read spokes 3 and 4 together.
If you operate in a regulated sector (FCA, education, healthcare): the sector-specific spoke is the starting point.
