What the m365 / workspace hardening checklist covers
The checklist is vendor-neutral: the control questions apply across platforms, and a dedicated command reference gives the exact command or console path per platform. The 10 control domains are:
- Identity & Authentication
- Conditional / Context-Aware Access
- Admin Governance
- Email Security
- Collaboration & External Sharing
- Data Protection & DLP
- Application & OAuth Governance
- Audit Logging & Alerting
- Device Access
- Backup, Retention & Recovery
Which platforms it applies to
One checklist, every platform. The command reference covers:
- Microsoft 365 (Entra / Exchange / SharePoint)
- Google Workspace
How auditors use it
Work top to bottom, set each control to Pass, Fail, Partial, Not Applicable or Not Tested, and attach an evidence reference. The Excel workbook includes a live dashboard (pass rate, open findings by priority), a findings register, an evidence-request list and a weighted risk-scoring model — so the review becomes a repeatable, evidence-based exercise.
Framework mapping built in
Every control carries practical mappings to CIS Benchmarks and CIS Controls v8.1, NIST CSF 2.0, ISO/IEC 27001:2022, PCI DSS v4.0.1 and the UAE IA / KSA ECC regional controls — so one review evidences several obligations at once. The mappings are practical audit mappings, not a substitute for the licensed text of each standard.
Frequently asked questions
What is a m365 / workspace hardening checklist?
It is a structured list of security controls used to reduce attack surface and configure m365 / workspace securely. This one contains 32 controls, each with a test method, the evidence to collect and the risk if it is missing.
Which platforms does it cover?
The control questions are vendor-neutral and a dedicated command reference gives the exact command or console path for Microsoft 365 (Entra / Exchange / SharePoint), Google Workspace.
Is it aligned to CIS Benchmarks and PCI DSS?
Every control is mapped to CIS Benchmarks and CIS Controls v8.1, NIST CSF 2.0, ISO/IEC 27001:2022 and PCI DSS v4.0.1, plus UAE IA and KSA ECC — so a single review supports several compliance obligations.
What format is the download?
You get a 12-sheet Excel working checklist (with a live dashboard, findings register and command reference) and a matching PDF narrative workbook. Both are free.
Can CyberSigma run this review for us?
