Scope

Description

1. Summary of Requirements

L&Q intends to procure a hybrid Out‑of‑Hours Security Operations Centre service to operate as an extension of the internal L&Q SOC. The service will provide protective monitoring, triage, and incident response outside of core operating hours.

The OOH SOC partner will be responsible for:

Continuous monitoring, triage, and incident escalation during defined out‑of‑hours periods.

Supporting L&Q's internal SOC with investigations, analysis, and agreed incident response actions.

Operating in alignment with L&Q playbooks, processes, and security tooling (including Microsoft Sentinel, Microsoft Defender XDR, and others).

Providing structured shift handovers, monthly reporting, and ongoing collaboration with L&Q SOC staff.

This work is critical for maintaining security oversight during nights, weekends, and bank holidays, reducing the risk of compromise during periods where internal analysts are unavailable.
