Centralising threat visibility for an Irish healthcare organisation

The Client

A leading Irish healthcare provider delivering residential and community-based care services, supporting vulnerable individuals across multiple locations. The organisation operates in a highly regulated environment and manages sensitive patient, clinical, and operational data across its care services.

The Challenge

As digital systems expanded, the internal IT team found themselves monitoring security incidents across multiple disconnected platforms. Alerts were investigated in isolation, limiting visibility of overall risk and placing increasing pressure on a small team responsible for safeguarding sensitive healthcare data.

Key Challenges

Fragmented security monitoring across multiple platforms

No single, centralised view of incidents or threats

Manual, time-consuming investigation processes

Limited insight into severity and organisational impact

The Solution

CWSI worked with the organisation to design and deploy a centralised security operations platform, consolidating signals from Microsoft and third-party tools into a single SIEM while ensuring the internal team could manage it confidently.

Solution Components

Microsoft Sentinel deployment

Log Analytics workspace configuration

Integration with Microsoft and third-party security tools

Testing, knowledge transfer, and cost modelling

The Result

With all security data centralised, the organisation gained clearer visibility of threats and improved its ability to prioritise and respond to incidents effectively.

Key Outcomes

1

Single SIEM platform providing unified threat visibility

2

Faster incident correlation and investigation

3

Reduced operational strain on IT teams

4

Clear roadmap to consolidate endpoint protection into Microsoft Defender

Why CWSI

CWSI’s deep experience in financial services security and regulatory compliance enabled the bank to move beyond policy-driven controls to practical, enforceable solutions. By combining structured design, proof-of-concept validation, and hands-on implementation, CWSI ensured the controls were effective, user-friendly, and aligned with regulatory expectations.

“Microsoft Sentinel gives healthcare organisations the visibility they need to manage threats proactively rather than reacting to disconnected alerts. Centralising security operations not only improves response times but also reduces pressure on IT teams responsible for protecting highly sensitive patient data.”
