This work package provides organisations with expert guidance, assessment, and implementation support to adopt the NIST Zero Trust Reference Architecture (ZTRA). It covers identity, device, network, application, data, and workload security—integrating policy enforcement, continuous verification, and least‑privilege access across hybrid and multi‑cloud environments.
The service helps clients transition from perimeter‑based security to a modern, adaptive, threat‑informed Zero Trust model, aligned with NIST SP 800‑207, NIST ZT RA, and industry best practices.
Assess current security posture against NIST Zero Trust principles.
Design a Zero Trust architecture aligned to NIST ZTRA components.
Implement identity‑centric, policy‑driven access controls.
Reduce attack surface, lateral movement, and implicit trust.
Improve visibility, monitoring, and continuous verification.
Enable a phased, realistic Zero Trust transformation roadmap.
A complete Zero Trust maturity assessment and gap analysis.
A NIST‑aligned Zero Trust architecture blueprint.
Hardened identity, device, network, and data controls.
Policy decision and enforcement points (PDP/PEP) designed and integrated.
Improved detection, response, and adaptive access capabilities.
Clear governance, operating model, and transformation roadmap.
