Project

Enterprise Security E2E

Project Scope

Establishing a modern, enterprise-grade security function for one of the UK’s fastest-growing Managing General Agents and brokerage groups. The end-client operates across three continents with entities spanning the UK, Europe, and Asia-Pacific, expanding dynamically through M&A operations.

The scope focuses on hardening a complex hybrid Microsoft environment, unifying fragmented security tooling across a multi-entity ecosystem, and driving a consistent, governed, and resilient security baseline across the entire Group.

Legacy, reactive security practices are being replaced with a Zero Trust architecture – deploying Microsoft’s full security stack across identity, endpoints, cloud apps, data, and network. The project aims at strengthening detection and response capabilities to protect a high-growth insurance business operating under Lloyd’s, UK GDPR, and MAS regulatory frameworks.
