We keep a record of how your Microsoft 365 tenant is secured.
NebulaCore Inc is a California software company. We build one product: configuration snapshots, drift detection and rollback for Microsoft 365 security settings.
Why this problem
A Microsoft 365 tenant holds hundreds of security settings across Entra ID, Conditional Access, Intune, Defender and Exchange Online. They get changed for good reasons: a vendor needs access, a device will not enroll, a policy blocks a sales trip. Many of those changes are never reverted.
The admin centers show the current state, but not what the state was last month or who approved the difference. NebulaCore fills that gap with a versioned history and a review step for every change.
Our customers are IT managers and security leads at companies of 50 to 300 people who already run Microsoft 365 and want to know their settings still match what they signed off on.
How we work
Least privilege first
We ask for read-only Microsoft Graph permissions and keep write access for rollback as a separate consent you control.
Configuration, never content
We store policy objects and role assignments. Email, chats and files stay in your tenant.
Your data stays portable
Every snapshot can be exported as JSON. If you leave, you take your full history with you.
Two people for every rollback
Changing a production security setting should never depend on one person's judgment at 2 a.m.
