My Security Architecture Design, Review, and Development service enables organizations to build robust, scalable, and resilient security foundations aligned with business goals. I conduct comprehensive security architecture reviews to identify gaps and ensure alignment with industry best practices and frameworks such as NIST, ISO 27001, and CIS Controls. I design and develop tailored Security Architecture Designs (SAD) supported by professional, easy-to-understand architecture diagrams that clearly map controls, data flows, and trust boundaries. By implementing defence-in-depth strategies, I ensure multiple layers of protection across networks, applications, endpoints, and cloud environments. The service delivers a structured, risk-driven architecture roadmap that enhances security posture, ensures compliance, and supports secure digital transformation initiatives.
