Case Study

Securing 300+ Applications for a Global Insurance Leader with Adarma’s custom SIEM and SOC services

About the Customer

A leading global insurance provider offering a range of insurance and financial services in over 50 countries.

Customer Challenges and Requirements

The customer needed to secure more than 300 applications across their environment while maintaining rapid detection and response to emerging threats. With the threat landscape constantly evolving, they required a robust solution to protect critical assets and sensitive data without disrupting business operations.

Adarma’s Solution

Adarma delivered a comprehensive managed security service built around Microsoft Sentinel, tailored to the customer’s complex application environment. At the core of the solution was an agile use case factory, designed to rapidly develop, test, and deploy detection and response rules aligned to evolving threats.

To ensure effective coverage, Adarma conducted a detailed assessment of the customer’s cybersecurity posture using the MITRE ATT&CK Framework. Our team then developed custom detection logic, enabling focused monitoring across critical assets.

We provided dedicated security analysts and engineering support to manage and optimise the customer’s global SIEM, leveraging innovative data ingestion techniques to accelerate onboarding. Our service also included ongoing threat detection tuning, rule refinement, and collaboration with the customer’s internal team to embed best practices across their security operations.

Outcomes Delivered

Adarma established an agile use case factory that facilitated the rapid deployment of security measures and successfully monitored over 300 applications through the customer’s global SIEM solution, Azure Sentinel. Adarma developed and integrated detection and response rules into the customer’s global SIEM platform, significantly reducing ongoing maintenance through generic and consistent use case development. In addition, Adarma augmented the customer’s security operations team, providing immediate access to specialist skills and experience, strengthening their overall cybersecurity posture.
