Unosecur unveils Office 365 Connector to eliminate dormant accounts and shadow admins, strengthen identity security

Berlin, Germany – 3 June 2025
Unosecur, the European identity-security specialist protecting human and non-human identities across multi-cloud environments, today announced the general availability of its native Office 365 Integration. With this, Unosecur has extended the platform’s continuous identity visibility to Exchange, SharePoint, OneDrive, and Teams.

The new Office 365 Connector - the latest addition to Unosecur’s comprehensive identity security platform - comes at a time when sprawling enterprises struggle with dormant mailboxes, guest users, and ‘shadow admins’ cropping up faster than most security teams can track. 

By wiring Office 365 directly into its Unified Identity Fabric, Unosecur has turned that sprawling access jungle into a single, living map, so that security teams can fix gaps before attackers find them.

“One of our customers discovered more than 400 guest and contractor accounts in Office 365 that no one even remembered creating. That’s exactly the mess we built this connector to clean up. In a single dashboard you see every mailbox, token and shadow-admin path,” said Timm Lotter, Head of Solution Engineering, Unosecur.

“When you have that level of granular visibility, you can disable the risky ones with a click, right there while the coffee’s still hot.” 

Key capabilities

• Unified posture management: Inventories every user, guest, service principal, and API token across O365 workloads, flagging access sprawl, inactive or orphaned accounts, non-MFA logins, SSO bypasses, and privilege drift.
• Dormant-account radar and one-click remediation: Highlights identities idle for 90 days (configurable) and lets analysts disable, de-licence, or quarantine them in-line, with every action auto-logged for audit.
• Shadow-admin spotlight: Traces nested Azure AD/Entra groups to surface hidden global-admin paths and over-privileged service accounts.
• Agentless deployment: Connects in minutes via Microsoft Graph with read-only scopes; zero impact on end-users or IT workflows.

Early enterprise pilots report a 65 percent reduction in mean time to remediate Office 365 identity threats by correlating O365 signals with cloud-native findings in one dashboard.

“Attackers know a single forgotten mailbox can be a golden back door,” added Santhosh Jayaprakash, Chief Executive Officer, Unosecur. 

“With first-class Office 365 support, our platform now secures every path that matters, whether it starts in a dev repo, a cloud console, or the CEO’s inbox.”
