Microsoft 365 that works
the way your business does
Microsoft 365 is one of the most powerful business tool suites available — and one of the most under-configured. W3IT sets it up properly, migrates your existing email and files, and keeps it running securely so your team can focus on work, not IT.
We use Microsoft 365 to run W3IT. Our own tenant is configured with Conditional Access, MFA enforcement, DLP policies and Defender for Business — the same setup we build for clients. We know what works in practice, not just in documentation.
Most M365 tenants are one mistake from a breach
Microsoft 365 ships with permissive defaults designed for broad compatibility, not security. Without deliberate hardening, your tenant is exposed in ways you may not realise.
- No MFA enforced Password spray and credential stuffing attacks compromise M365 accounts daily. MFA blocks over 99.9% of these attacks — but it must be enforced, not just enabled.
- Email authentication not configured Without SPF, DKIM and DMARC, your domain can be spoofed for phishing. M365 doesn't configure these automatically — you have to set them up in your DNS.
- Overshared SharePoint and OneDrive Default sharing settings allow "anyone with the link" to access files. One forwarded email means client data is accessible to anyone on the internet.
- No backup Microsoft 365 is not a backup solution. Deleted items are recoverable only within short retention windows. Ransomware can reach synced OneDrive files.
Microsoft 365 — configured properly
From initial setup to ongoing management, we cover every part of your M365 tenant.
Tenant Setup & Email Migration
New tenant provisioning, domain verification, MX record configuration and email migration from your current provider (Google Workspace, Hostinger, cPanel, or another Exchange environment). Migration is staged to avoid any mail delivery gaps.
Security Hardening
MFA enforcement via Conditional Access policies (not just per-user MFA which can be bypassed), secure score review, Defender for Business configuration, Data Loss Prevention policies, external sharing restrictions and legacy authentication blocking.
Email Authentication (SPF, DKIM, DMARC)
Correct SPF record configuration for Exchange Online (including third-party senders), DKIM signing key setup, and DMARC policy from monitoring through to enforcement. We also configure DMARC reporting so you can see who is sending email on your behalf.
Teams, SharePoint & OneDrive
Teams governance setup, SharePoint site provisioning, OneDrive sharing policy configuration and sensitivity label deployment. We design your collaboration structure so that sharing is easy internally and controlled externally.
Backup & Recovery
Third-party backup for Exchange, SharePoint and OneDrive with configurable retention periods and point-in-time restore. This is separate from Microsoft's built-in retention policies and protects against accidental deletion, ransomware and tenant misconfiguration.
What we commit to
Zero Email Downtime
Email migrations are staged and tested. We don't cut over until the new environment is fully verified. Typical migration has zero delivery gaps.
Security Score Improvement
We will improve your Microsoft Secure Score by a measurable amount. If we can't identify actionable improvements, we'll tell you before you pay.
Staff Training Included
New setup or migrations include a walkthrough session for your team covering the tools they'll use most and the security practices they need to follow.
Your Data, Your Tenant
We work inside your Microsoft tenant — your data never touches our infrastructure. Admin access is revoked after any project at your request.
