Endpoint protection — all devices running current EDR/AV with automatic patching enabled
Every endpoint (laptop, desktop, server) must be protected by an Endpoint Detection and Response (EDR) solution — not just legacy antivirus. EDR provides behavioural detection capable of identifying ransomware before full encryption. OS and software patching must be automated with a defined maximum patch window (Critical: 72 hours, High: 7 days).
Trigger
When this rule fires
Endpoints running legacy antivirus without EDR capability; automatic patching disabled; unpatched critical CVEs on production systems; personal/unmanaged devices used to access client data
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
Deploy a modern EDR solution (e.g., Microsoft Defender for Endpoint, CrowdStrike, SentinelOne). Enable automatic OS patching. Implement a patch management policy with defined SLAs by severity. Ensure all endpoints are managed and enrolled.
Evidence required
Evidence to prepare if this control applies
- EDR deployment report (coverage across all devices)
- Patch compliance report (last 30 days)
- Unmanaged device inventory showing zero client-data-accessing unmanaged devices
- Patch management policy with SLAs
