Questions buyers ask
Is this checklist a formal cybersecurity audit?
No. This checklist is a practical starting point for reviewing common Microsoft 365 and cyber risk areas. A formal audit or assessment should be scoped separately.
Why does Microsoft 365 need a separate risk checklist?
Microsoft 365 often holds email, files, identities, collaboration tools, and business records. Access, sharing, backup, and incident readiness are worth reviewing regularly.
What should we review before Microsoft Copilot or AI rollout?
Start with permissions, external sharing, sensitive files, guest users, admin controls, and acceptable-use guidance. AI tools can make existing access and governance gaps easier to surface.
Can K3 help us review this checklist?
Yes. K3 can help leadership and IT teams review the checklist, identify priority gaps, and decide which Microsoft 365 security and readiness steps matter most.
