Microsoft 365 is the operating system of many SMBs—email, files, chat, and identity in one tenant. That concentration is efficient and high-risk. These basics materially improve security without requiring a full enterprise project.
Identity and admin hygiene
- MFA for all users; stronger methods for admins
- Separate admin accounts from daily driver mailboxes
- Minimize global admins; use least privilege roles
- Review enterprise applications and OAuth consents

Sharing and data location
- Know whether SharePoint/OneDrive links are “anyone,” organization, or specific people by default
- Limit external sharing where business allows
- Review abandoned Teams and guest users
Email threat protection
Enable the protections included in your licensing tier, reduce legacy protocols where possible, and treat compromised mailboxes as incident response events—not IT annoyance tickets.
Secure Score as a conversation tool
Microsoft Secure Score is not a grade for the internet. It is a prioritization aid. Use it to track improvement, not to chase vanity points that break operations.
