Microsoft 365 is where many businesses keep email, files, Teams chats, calendars, and client data. That makes it one of the most important systems to secure. Default settings are not enough for most businesses.
Small businesses often grow into Microsoft 365 without cleaning up admin roles, mailbox forwarding, guest sharing, legacy access, retention, or backup. That creates unnecessary risk.
For South Florida businesses with remote teams, medical data, client files, or regulated workflows, Microsoft 365 needs to be intentionally configured and reviewed.
What to look for
- Enforce MFA for every user and administrator.
- Review admin roles and remove unnecessary privileges.
- Check mailbox forwarding and suspicious inbox rules.
- Configure SPF, DKIM, and DMARC.
- Back up Microsoft 365 data separately from Microsoft itself.
