Native vs middleware
The 18 tools below ship a native Microsoft 365 integration: OAuth handshake, no Zapier in the middle. Middleware (Zapier, Make, n8n) is a good fallback for tools that don't ship native, but adds a per-task cost and a delay step.
Before you turn it on
Confirm sync direction (one-way or two-way), check which Microsoft 365 plan or workspace permissions are required, and run a test record through before connecting production data. Most setups take under 10 minutes.

Microsoft 365 integration FAQ
What is the best security tool with Microsoft 365 integration in 2026?
GitLab ranks first in our security list with Microsoft 365 integration, rated 4.6/5 across 2,085 verified user reviews. Strong runners-up: NinjaOne, iDrive, KnowBe4.
How does Microsoft 365 integration work in security software?
Most security tools connect to Microsoft 365 via OAuth: you sign in from inside the tool, approve scopes, and data starts syncing. Sync can be one-way (push only) or two-way (bidirectional). GitLab uses a native Microsoft 365 integration that you can usually enable from the integrations or apps section of the dashboard.
Are there free security tools with Microsoft 365 integration?
Yes. GitLab, iDrive, Veeam offer a free or freemium plan with Microsoft 365 connectivity. In total, 5 of the 18 tools on this list have a free or freemium tier.
Native Microsoft 365 integration vs Zapier: which is better?
Native integrations sync in real time, support deeper data mapping, and rarely break when Microsoft 365 updates its API. Zapier (or other middleware like Make and n8n) lets you connect tools that don't ship a native integration, but adds a step that can introduce delays and a per-task cost at higher volumes. The 18 tools on this list all ship a native Microsoft 365 integration so middleware is optional.
How often is this list updated?
We refresh editorial scores and integration availability weekly. Pricing is re-checked on a rotation that touches every tool roughly monthly. The list above was generated on June 26, 2026.
