From 3rd‑Party SIEM to Sentinel 

Many NHS Trusts are still reliant on legacy, third‑party SIEM platforms that are costly to run, complex to manage, and disconnected from the wider Microsoft security estate.

At the same time, Microsoft Sentinel has matured rapidly, offering a cloud‑native, NHS‑aligned SIEM that integrates directly with Microsoft Defender, Entra ID, and the wider Microsoft Security stack.

In this webinar, we’ll explore how NHS organisations are successfully migrating from legacy SIEM tools to Microsoft Sentinel, reducing complexity, improving visibility, and aligning more closely with national security strategies, without compromising operational resilience or compliance.

This session is designed for NHS Trusts and ICBs considering a move to Sentinel or looking to modernise their security operations.
