The organisation lacked a centralised capability to monitor security events across multiple technologies, resulting in limited visibility, slower incident detection, and fragmented security operations.
Security telemetry was distributed across Microsoft 365, Active Directory, firewalls, endpoints, cloud services, and critical business applications, making it difficult for security teams to identify patterns, correlate events, and respond to threats efficiently.
The Challenge
The organisation's security operations were impacted by fragmented visibility across its technology environment.
Security events and logs were generated across multiple systems and platforms, but the absence of a centralised SIEM capability made it challenging to monitor activity, correlate security events, identify potential threats, and respond quickly to incidents.
The organisation required a scalable security operations capability that could bring together security telemetry from across the enterprise and provide security teams with a unified view of cyber activity.
Effective security operations depend on visibility. By bringing security data together in one centralised platform, organisations can detect threats faster, investigate incidents more effectively, and make better-informed cyber risk decisions.
Our Approach
Abiryva consultants implemented and optimised an enterprise Security Information and Event Management (SIEM) capability to centralise security monitoring and improve the organisation's overall security operations.
The SIEM capability integrated security telemetry from Microsoft 365, Active Directory, firewalls, endpoints, cloud services, and critical business applications, creating a unified platform for security monitoring, threat detection, investigation, and response.
The engagement included:
- SIEM Design & Implementation
- Log Source Integration
- Detection Rule Development
- Security Dashboard Creation
- Incident Response Playbooks
- Threat Hunting
- Executive Reporting
Establishing Centralised Security Visibility
The implementation established a centralised security monitoring capability across the organisation's enterprise technology environment.
By integrating security telemetry from multiple sources, the organisation was able to correlate events across systems, identify suspicious activity, and provide security teams with a more complete understanding of potential threats.
Detection rules, security dashboards, threat hunting capabilities, and incident response playbooks were developed to support a more proactive and efficient approach to security operations.
