Microsoft 365 is the backbone of most construction IT environments — but default settings are not secure enough for jobsite operations.
Improper configuration can result in:
- Email compromise
- File-sharing errors
- Lost project data
- Insurance non-compliance
Here’s how to configure Microsoft 365 correctly.
1. Enforce MFA Across All Accounts
Required for:
- Outlook
- SharePoint
- Teams
- Admin accounts
MFA should not be optional.
MFA is now a baseline insurance requirement. Construction companies reviewing Microsoft 365 security should understand the full scope of cyber insurance requirements for construction companies.
2. Structure SharePoint for Project-Based Access
Avoid dumping files into one shared folder.
Instead:
- Create project-based libraries
- Restrict access by role
- Use expiration rules for external sharing
Not sure where you stand? We help construction companies identify IT risks, insurance gaps, and jobsite issues before they become problems.
3. Enable Advanced Email Protection
Use:
- Anti-phishing policies
- DMARC/SPF/DKIM
- Attachment sandboxing
Construction companies are prime invoice fraud targets.
4. Implement Conditional Access Policies
Restrict:
- Foreign logins
- Risky IP addresses
- Non-compliant devices
5. Manage Devices with Endpoint Control
Require:
- Encryption
- Compliance checks
- Remote wipe capability
Poor device management often leads to preventable outages. Contractors should also understand what acceptable IT response times for active construction jobsites should look like when issues occur.
Real Example
A GC with 61 employees reduced phishing incidents by over 70% after enabling advanced email protection and conditional access.
Final Takeaway
Microsoft 365 must be configured for a mobile, multi-location workforce — not a static office.
