Phishing simulation — regular simulated phishing tests conducted; failure rates tracked and reducing

Phishing simulations are the most effective way to measure and improve staff resilience against email-based attacks. Simulations must be conducted at minimum quarterly, with failure rates tracked over time and declining. Staff who fail must receive immediate targeted training — not disciplinary action.

Medium priority

Trigger

When this rule fires

No phishing simulation programme; simulations conducted less than quarterly; failure rates not tracked or not declining over time

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.

Remediation

How to close the gap

Implement a phishing simulation platform. Run monthly or quarterly simulations varying attack type (credential harvest, malware, BEC). Track click-through and report rates. Auto-enrol failures in targeted training.

Evidence required

Evidence to prepare if this control applies

  • Phishing simulation platform configuration
  • Simulation results (last 4 campaigns) with click rates
  • Failure rate trend showing improvement
  • Targeted training completion for failures
