Summary
Key results
100% of the client’s IT environment covered by security monitoring
About 50% reduction in false-positive alerts
Need of a consistent security monitoring
Operating a global IT environment required the client to maintain consistent security oversight and incident handling across the organization. However, the existing setup needed more effective monitoring and better configuration of the security tools already in place.
More specifically, the client wanted to improve the way suspicious activity was identified and addressed. It also needed a structured view of its current security posture across governance and technical controls, including gaps and areas requiring improvement.
The engagement had to cover the full IT environment, with the main focus on the headquarters environment. The client selected Sii Poland to establish a clear security baseline and strengthen ongoing threat detection and response.
From security assessment to operational monitoring and response
Sii Poland assessed the client’s cybersecurity profile against ISO 27001 requirements, reviewed its technical security posture, and identified gaps and improvement areas. The team also supported the implementation of selected recommendations. After a 2-month transition, the service moved into an 8/5 operating model.
The scope included:
- Establishing monitoring across the complete IT environment, with the main focus on headquarters systems and infrastructure
- Integrating security monitoring, orchestration, and automation with the client’s IT service management workflow
- Introducing automated playbooks, analyzing suspicious activity, triaging alerts, and investigating security incidents
- Coordinating mitigation, threat isolation, and stakeholder communication when required
- Closing false positives and providing monthly service reports
Broader visibility and less alert noise
The 8/5 service established structured monitoring across the client’s entire IT environment, improving threat visibility and enabling more consistent assessment of incidents according to their significance and potential impact.
The number of false-positive alerts fell by about 50%, reducing non-actionable alert noise.
Automated playbooks and integration with the client’s IT service management workflow created a more structured incident-response process. The operating model covered triage and investigation, followed by mitigation, threat isolation, and stakeholder communication when required.
The security assessment also gave the client a structured view of governance and technical improvement areas. Sii Poland supported the implementation of selected recommendations, helping address identified gaps and strengthen the client’s security posture.
