Microsoft 365 Security: 7 Controls Small Businesses Should Review

Microsoft 365 often contains a company's email, files, identities, collaboration tools, and sensitive business data. A few configuration weaknesses can therefore have an outsized impact.

Seven areas to review

Review multi-factor authentication, administrator accounts, legacy authentication, external sharing, mailbox forwarding, endpoint access, and audit/security alerting.

Focus on configuration, not just licensing

Buying Microsoft security features does not guarantee they are configured effectively. Security posture depends on how identity, sharing, devices, and administrative privileges are actually managed.

A Microsoft 365 security assessment can identify quick wins, misconfigurations, and longer-term improvements without requiring an enterprise-sized security program.
