Kenneth Nnorom
Designing, implementing, and securing complex, large-scale network infrastructures. Specializing in multi-vendor firewalls, data centre fabrics, OT/IT convergence, and resilient defensive architectures.
Professional Overview
“I focus on building multi-layered security strategies that align technical configuration with strategic risk mitigation, eliminating technical debt and delivering deterministic uptime.”
As a Network Security Engineer with nearly a decade of progressive industry experience across energy, technology, and managed services sectors, I architect and defend infrastructures where reliability is non-negotiable. My expertise spans multi-vendor firewalls (Cisco, Fortinet), IDS/IPS, IPsec/SSL VPNs, 802.1X NAC, and modern data centre fabrics.
Beyond technical configuration, I lead vulnerability management lifecycles, deploy unified SIEM/XDR platforms (such as Wazuh), and establish robust ICT governance frameworks aligned with NDPR and ISO 9001 standards. Having mentored SOC teams and junior engineers, I bridge the critical operational gap between low-level packet mechanics and executive security governance.
