About Me

Defending with precision

Security is not a product — it's a discipline built on vigilance, curiosity, and decisive action.

With a background in Networks and Communication Systems and hands-on experience as an Information Security Officer at Postbank Kenya, I specialize in threat detection, SIEM implementation, risk assessment, and regulatory compliance.

Currently completing a Cybersecurity Graduate Certificate at Durham College (Oshawa, Ontario), graduating June 2026. Open to full-time cybersecurity roles across Canada.

Zero Non-Conformities: A Framework for Audit Readiness

Achieving zero major non-conformities requires aligning policies, people, and processes well in advance — not just at audit time. Sustained compliance is a continuous discipline, not a one-time event.

Threat Detection · SIEM

Alert fatigue is the enemy of effective SOC operations. Fewer, higher-fidelity ArcSight alerts — carefully configured and regularly reviewed — dramatically improve detection speed and accuracy.

Risk assessments are only as valuable as their follow-through. A structured cadence of identify → prioritize → remediate → verify keeps the threat surface steadily shrinking over time.
