Security Architecture
I design Microsoft-native detection and response that cuts noise and finds real threats, built on Defender XDR and Microsoft Sentinel under a Unified SecOps model.
Problems I help solve
What I deliver
Defender XDR Deployment and Tuning
Advanced rule tuning across identity, endpoint, email, and cloud.
- What I deliver
- A Defender XDR deployment plan and tuned detection policies across the suite, with unified incident handling.
- Business outcome
- Reduced SOC alert fatigue by 61%.
- Defender XDR
- Defender for Cloud
Unified SecOps on Sentinel
Cloud-native SIEM and SOAR replacing legacy tools.
- What I deliver
- A Microsoft Sentinel workspace, data strategy, and analytics under a Unified SecOps model with Defender.
- Business outcome
- Faster, cleaner detection and response.
- Microsoft Sentinel
- KQL
KQLDetection Engineering
Coverage mapped to the MITRE ATT&CK framework.
- What I deliver
- KQL analytics and hunting queries mapped to MITRE ATT&CK, with documented coverage gaps.
- Business outcome
- Threat coverage you can see and defend, not assume.
- KQL
- MITRE ATT&CK
Response Automation
Playbooks for routine triage and containment.
- What I deliver
- Automated playbooks for triage and containment of common incident types.
- Business outcome
- Analysts focus on real threats, not noise.
- Sentinel Playbooks
- Logic Apps
Cloud Security Posture (CNAPP)
Defender for Cloud, Secure Score, and posture management.
- What I deliver
- A cloud-native posture programme with Secure Score uplift and continuous CSPM across the estate.
- Business outcome
- Misconfiguration and drift caught before they become risk.
- Defender for Cloud
- CSPM
- Secure Score
Threat Hunting and Incident Response
Proactive hunting and structured IR.
- What I deliver
- Hypothesis-driven hunts in KQL and a structured incident response process across Defender and Sentinel.
- Business outcome
- Threats found and contained, not just alerted on.
- Defender XDR
- KQL
- Sentinel
Email and Collaboration Security
Defender for Office hardening.
- What I deliver
- Hardened anti-phishing, safe links and attachments, and collaboration protections.
- Business outcome
- The most common attack path closed.
- Defender for Office 365
Vulnerability and Exposure Management
Continuous vulnerability management.
- What I deliver
- Continuous vulnerability discovery and risk-based prioritization across the estate.
- Business outcome
- Exposure reduced and prioritized by real risk.
- Defender Vulnerability Management
Outcomes
61% reduction in SOC alert fatigue
Legacy SIEM retired for cloud-native Unified SecOps
