Cyber risk register — documented, classified by criticality, reviewed quarterly
A formal cyber risk register must identify, describe, and rate all material cyber risks facing the organisation. Risks must be classified by likelihood and impact, mapped to controls, and reviewed at least quarterly with findings escalated to governance.
Trigger
When this rule fires
No cyber risk register, or register not reviewed in last 6 months, or risks not classified by likelihood and impact
Applicability gate
Confirm the entity's role before treating this as a duty
This is a readiness rule mapped to JS2 themes. Its presence in the library does not establish that JS2 applies directly to the firm.
- Insurance Broker: Most independent non-life Category I brokers are not directly in JS2's defined scope. A broker may be directly in scope if it separately meets a listed category, and may face contract or oversight requirements from an in-scope institution. Third-party provisions impose duties on the in-scope financial institution. They do not themselves make every supplier or intermediary directly subject to JS2.
- Uma Binder Holder: UMA or binder-holder status is not itself listed in JS2's definition. Direct scope depends on another listed capacity; insurer contracts and oversight may create evidence requirements. JS2 paragraph 3.3 concerns juristic persons structured under an insurer or designated insurance group; it is not a blanket rule for every independent UMA or intermediary.
- Insurer: An insurer as defined in the Insurance Act is directly in scope of JS2 from 1 June 2025. Apply proportionality and distinguish the insurer's own duty from requirements it places on third parties.
