Cover image for Deployed a cloud-native SIEM integrating
Deployed a cloud-native SIEM integrating Microsoft Azure infrastructure, Windows endpoints, Microsoft 365, and Defender XDR telemetry into a unified detection and response platform. Wrote KQL analytics rules for real-time threat detection covering: privilege escalation, suspicious PowerShell execution, lateral movement via RDP and SMB, anomalous Azure AD sign-ins, and malware execution patterns. Automated incident response using Azure Logic Apps. Reduced log ingestion costs by 20% through optimised data collection, balancing coverage against cost without losing detection fidelity.

Cover image for Built a complete enterprise-grade SOC
Built a complete enterprise-grade SOC environment from scratch: featuring Wazuh SIEM with custom detection rules, Security Onion with Suricata IDS/IPS and Zeek network monitoring, Active Directory with advanced security logging via Group Policy, and Windows Server with Sysmon telemetry. Designed and executed MITRE ATT&CK-aligned attack simulations from Kali Linux and validated detection coverage through red team exercises. Achieved over 95% detection rate across all tested techniques and tactics. This project served as the foundation for understanding how detection engineering decisions translate into real gaps and how to close them.
