Property Cyber and Data Exclusion

Nothing. This is the absolute property exclusion: the harder twin of 5400, with no write-back at all.

Excludes both malicious cyber acts and non-malicious cyber incidents, with no saving clause, together with any loss or cost of repairing or replacing data. The same six wide exclusions and the same anti-concurrent causation language as 5400, stripped of the fire and explosion write-back.

In practice kept for catastrophe (CAT) markets, where the insurer will accept no residual cyber exposure at all. On mainstream property policies the market went with 5400 instead.

Its absolute character leaves material holes in the insured's cover, which is precisely what pushed brokers and markets towards 5400. The in connection with language can take out losses with only a thin link to a cyber event.

Issued 13 November 2019 alongside 5400, for the silent cyber mandate of 1 January 2020. Imposed at first by some major property markets, before the market converged on 5400 as standard and left 5401 to CAT.
