Our Assessment Stack

7 Layers. 4 Frameworks. 1,100+ Checks.

We don't run one tool — we run four configuration engines, an attack path analyzer, Microsoft's own scoring APIs, and a full email security audit. Then we correlate everything.

⚡

4 Configuration Engines Combined

Microsoft Zero Trust Assessment, Maester (280+), CISA ScubaGear (100+), and M365SAT CIS Benchmarks — deduplicated into one 700+ test baseline scan.

🕸️

BloodHound Attack Path Analysis

Maps every privilege escalation route in your Entra ID. Finds paths like "Help Desk → Global Admin in 3 hops" that no compliance framework checks.

📊

Secure Score + Identity + Compliance

Pulls your Microsoft Secure Score (411+ controls), Identity Secure Score, and Compliance Score — then cross-references with our scan findings.

📋

Auto-Mapped to 4 Frameworks

Every finding automatically mapped to NIST 800-53, CIS Benchmarks, ISO 27001, and CMMC. Audit-ready reports with direct admin portal fix links.

Common Questions

Frequently Asked Questions

A Zero Trust Assessment evaluates your Microsoft 365 tenant against 1,100+ security checks across 7 layers. We combine Microsoft's official Zero Trust Assessment, the Maester framework (280+ Pester tests), CISA ScubaGear (100+ controls with OPA engine), BloodHound attack path analysis, and Secure Score API (411+ controls). It identifies configuration gaps across Entra ID, Intune, Defender, Exchange Online, SharePoint, Teams, and Power Platform, then provides a prioritized remediation roadmap with direct links to the admin settings you need to change.

A full-time CISO typically costs $338,000+ per year in salary alone. TenantShield's vCISO services start at $5,000 per month, giving you strategic security leadership, compliance oversight, incident response planning, and quarterly business reviews at a fraction of the cost.
