Strengthening Cyber Defences for a Global FTSE 250 Insurance Group

About the Customer

A FTSE 250 specialist insurance group with a global footprint and expertise across diverse markets.

Customer Challenges and Requirements

The customer handles highly sensitive data, including financial, personal, and proprietary information, and is required to meet a high standard of regulatory and compliance obligations. As such, they wanted to strengthen and mature their cybersecurity posture and improve their detection and response capability. They were looking for a flexible, transparent solution backed by a proven Security Operations Centre (SOC) that could adapt to their evolving needs in an increasingly complex threat landscape.

Adarma’s Solution

Adarma worked closely with the customer to design and deliver a tailored, end-to-end security solution aligned to their operational goals and risk profile.

The engagement began with a detailed Cyber Maturity Assessment to identify gaps, prioritise improvements, and shape the strategic direction of the programme. From there, Adarma implemented a fully managed SOC, providing 24/7 monitoring, detection, and response capabilities across the customer’s estate.

Our services included managed detection and response (MDR), endpoint detection and response (EDR), and continuous threat intelligence to ensure proactive defence and rapid containment of threats. To enhance visibility and control, Adarma developed and refined SIEM use cases mapped to the MITRE ATT&CK framework, aligning detection logic with known adversary tactics and behaviours.

The solution is supported by a dedicated team of security analysts and engineering resources who operate as an extension of the customer’s internal team, ensuring rapid response, ongoing optimisation, and alignment with evolving business and threat priorities.

Outcomes Delivered

Adarma carried out a comprehensive Cyber Maturity Assessment, resulting in a security roadmap aligned to the customer’s business objectives. By leveraging the customer’s existing technology, we enhanced their overall cybersecurity effectiveness and strengthened the capabilities of the customer’s in-house security team, particularly around the SIEM platform.

The implementation of our Managed SOC service significantly increased MITRE ATT&CK coverage and reduced response times. This was further enhanced by the successful deployment of a Managed EDR service, which accelerated threat response and enabled more effective task prioritisation through improved MITRE ATT&CK alignment.

Adarma’s Expertise

Adarma seamlessly integrates into customer security operations, offering clear communication, an ISO27001-accredited managed SOC-as-a-service, and flexible services designed around specific operational needs. This ensures rapid access to optimised tools and continuous, high-quality threat management.
