Core Expertise
Proven results in secure cloud design, migration, and cyber security architecture.
Secure AWS & Azure Architecture
Designing secure, scalable, and resilient cloud architectures across AWS and Azure, including enterprise platforms, hybrid environments, and secure cloud integrations.
Zero Trust & Security-by-Design
Applying Zero Trust and secure-by-design principles through identity-driven access control, API security, threat modelling (STRIDE), and layered security architecture.
Cloud Migration
Supporting secure cloud migration programmes from on-premise infrastructure to AWS and Azure, ensuring strong
governance, resilience, and reduced operational risk.
API Security & Threat Modelling
Designing and assessing secure APIs using threat modelling methodologies such as STRIDE, identity-based security controls, and secure integration principles.
AI Security & Governance
Helping organisations adopt AI securely through governance frameworks, LLM security architecture, risk management, data protection, and secure AI integration patterns.
OT Security & Network Segmentation
Designing secure OT and industrial network architectures using segmentation, IDMZ patterns, controlled access models, and secure communication boundaries.
Enterprise & Critical Infrastructure Experience
Experience delivering secure architecture and cyber security solutions across government, critical national infrastructure, manufacturing, and enterprise environments with complex governance and regulatory requirements.
