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
