Zero Trust Framework
Zero Trust is not a product you buy or a feature you enable. It's the outcome of engineering every layer of your environment so that every access request is verified explicitly — regardless of where the user is or what device they're using. This engagement delivers a staged implementation roadmap across five layers with defined milestones.
The five layers of Zero Trust
Conditional Access framework, risk-based authentication, MFA enforcement, PIM, and service identity governance. The starting point of every Zero Trust programme.
Intune compliance policies, device health enforcement in Conditional Access, mobile application management, and endpoint threat signals feeding identity decisions.
Cloud App Security session monitoring, OAuth app governance, SaaS access controls, and Conditional Access app-level enforcement policies.
Sensitivity label classification, DLP enforcement across workloads, retention governance, and information protection that travels with the file.
Defender XDR correlation, Sentinel analytics, unified audit logging, and SOAR playbooks — building a monitoring posture that assumes breach has already occurred.
Where network segmentation intersects with your Microsoft 365 environment — Global Secure Access, Private Access, and named locations in Conditional Access.
The 30–60–90 day delivery model
Conditional Access framework, MFA enforcement, legacy authentication removal, privileged identity segmentation. The foundation everything else depends on.
Defender XDR onboarding and integration, Intune compliance policies, device trust signals feeding Conditional Access, Cloud App Security session monitoring.
Sensitivity label deployment, DLP enforcement, Sentinel analytics rules, automation playbooks, and comprehensive documentation for programme continuity.
What you receive
Every layer configured, validated, and documented. Delivered in milestones with stakeholder review at each checkpoint.
Stakeholder-ready documentation summarising the programme, outcomes achieved, current posture, and forward roadmap — designed for board or leadership review.
Complete architecture documentation, operational runbooks for every layer, and maintenance guide so your team can manage and extend what's been built.
Cross-tenant access and external trust governance
Modern enterprise attack paths no longer rely on exploiting your internal tenant directly. State-affiliated actors and sophisticated threat groups now specifically target cross-tenant trust relationships — B2B collaboration settings, external Entra ID connections, SaaS integrations, and managed service provider relationships that were set up informally and never reviewed. Once a trust relationship exists, it persists indefinitely unless explicitly removed. OAuth device code phishing campaigns — which achieved greater than 50% account compromise success rates across government, defence, and enterprise targets in 2024–2025 — specifically exploit the combination of open app consent and unreviewed cross-tenant access. A Zero Trust architecture treats every external trust relationship as a boundary that requires explicit scope, ongoing review, and time-bounded access.
Identity lifecycle governance
Enterprise tenants accumulate identity debt at a rate that manual review cannot keep pace with. Former employees whose accounts were disabled but not fully deprovisioned, contractors who retained access after engagement end, service accounts with broad permissions that nobody owns, app registrations from discontinued projects, and role assignments that outlasted the original justification — each one is a dormant credential an attacker can exploit without triggering normal activity-based alerts. Microsoft's own security guidance specifically highlights orphaned agents, unused connections, and unmanaged ownership as key risk factors in post-breach investigations. Identity lifecycle governance replaces ad hoc deprovisioning with automated, auditable processes that eliminate accumulation before it becomes exposure.
