TLS certificate grade — SSL certificate achieves minimum A rating on independent assessment

Trigger

When this rule fires

SSL certificate grades below A, or using deprecated TLS 1.0/1.1 protocols, or weak cipher suites, or certificate issued to wrong domain

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

Run SSL Labs test. Disable TLS 1.0 and 1.1. Enable TLS 1.3. Remove deprecated cipher suites. Enable OCSP stapling. Use a certificate from a trusted CA.
