This work package provides a structured consultancy engagement to design, implement, and operationalise a Zero Trust Network Access (ZTNA) capability. ZTNA replaces traditional perimeter‑based VPN models with identity‑centric, context‑aware access controls that continuously verify trust. The engagement ensures secure, granular, and adaptive access to applications, data, and services across hybrid and cloud environments.
The outcome is a modern, resilient access architecture aligned with Zero Trust principles, regulatory expectations, and organisational risk appetite.
Replace or augment legacy VPN with a modern ZTNA solution.
Enforce least‑privilege, identity‑driven access to applications and data.
Reduce attack surface by eliminating implicit trust and lateral movement.
Strengthen security posture through continuous verification and adaptive policies.
Improve user experience with seamless, secure, context‑aware access.
Align with Zero Trust frameworks (NIST 800‑207, CISA, Microsoft Zero Trust).
Activities
Stakeholder interviews (security, IT, cloud, operations).
Review of current remote access architecture (VPN, firewalls, IAM, MFA).
Assessment of identity maturity (Azure AD/Entra ID, Okta, Ping, etc.).
Application and data access mapping (on‑prem, cloud, SaaS).
Gap analysis against Zero Trust principles and regulatory requirements.
