Consolidating security platforms to strengthen protection and reduce cost for a public sector body
The Client
An Irish state financial body responsible for managing public assets, debt, and investment functions on behalf of the government. Operating under strict governance, transparency, and accountability requirements, the organisation manages highly sensitive financial, commercial, and government data and must maintain a strong security posture across its digital estate.
The Challenge
The organisation was operating a complex security landscape made up of multiple vendors and overlapping tools. This fragmentation increased cost, reduced visibility, and made it difficult for internal teams to manage threats effectively or gain a holistic view of risk across the environment.
At the same time, there was a clear requirement to strengthen security controls in line with public sector standards while also reducing operational overhead and simplifying day-to-day management. Any changes needed to be carefully governed to ensure continuity of critical public finance operations.
Key Challenges
- Fragmented security tooling across multiple vendors
- Limited integration and visibility across security platforms
- High operational and licensing costs
- Complexity in managing and supporting multiple solutions
- Requirement to meet strict public sector governance standards
The Solution
CWSI worked closely with the organisation to review its existing security estate and design a consolidated, Microsoft-based security framework. The focus was on simplifying the environment while improving protection through deeper integration across identity, endpoint, and cloud security.
CWSI provided strategic guidance and hands-on implementation support, helping the organisation transition to the Microsoft Defender security suite and retire redundant third-party tools. Ongoing managed services were put in place to support day-to-day operations and ensure continuous improvement.
Solution Components
- Comprehensive security assessment
- Strategic guidance on Microsoft Defender adoption
- Deployment of Defender for Endpoint, Identity, Cloud Apps, and Office 365
- Rationalisation and removal of overlapping third-party tools
- Ongoing managed security services
The Result
The organisation achieved a simpler, more integrated security architecture that improved visibility, reduced cost, and strengthened its overall security posture. By consolidating onto a single platform, internal teams gained clearer insight into threats and were better equipped to respond effectively.
Key Outcomes
- Reduced vendor sprawl through platform consolidation
- Improved threat visibility across identity, endpoint, and cloud services
- Lower operational and licensing costs
- Simplified security management and support
- Stronger alignment with public sector security standards
Why CWSI
CWSI’s experience working with government and state bodies ensured the security consolidation approach aligned with public sector governance, risk management, and accountability requirements. By balancing strategic advisory services with practical implementation, CWSI delivered a solution that improved security while reducing complexity and cost.
“Security consolidation is one of the most effective ways public sector organisations can improve protection while reducing operational complexity. By standardising on the Microsoft Defender platform, we helped the organisation achieve stronger visibility, better integration, and measurable cost savings without compromising governance.”
