Office 365 Security Risk Assessment - Find M365 Security Gaps

Run a full Microsoft 365 risk assessment: MFA gaps, risky users, admin changes, app consents, email threats, Teams/SharePoint exposure.

Office 365 Security Assessment

Secure, Audit, & Harden your M365

Instantly Identify M365 Risks Accross Your Entra ID Tenant

Instantly surface risks across Entra ID (Azure AD), Exchange, Teams, and SharePoint – from MFA coverage and risky users to admin changes, malicious email, app consents, and external sharing.

Close MFA Gaps Fast

See 100% of users/admins without MFA, exceptions, and trends. Prioritize high-risk admins and privileged roles first.

Catch Risky Sign-ins & Compromised Accounts

Track risky users, geo-impossible and unfamiliar sign-ins, password spray indicators, and failed admin logons.

Control Admin Sprawl

Inventory global admins, password-never-expires accounts, new admin creations, and disabled admins to enforce least privilege.

Stop Data Leakage in Teams & SharePoint

Spot public teams, guest access, shared/private channels, externally shared sites, inactive sites, and over-quota risks.

Block Malicious Email Paths

Quantify spam/phish/malware/spoof exposure and flag auto-forwarding policies that exfiltrate mail.

Tame App Consent Risk

Surface newly added apps, tenant-wide consent incidents, and service principal changes that introduce over-privileged access.

Microsoft 365 Security Risk Assessment using InfraSOS

Microsoft 365 concentrates identities, mail, files, and collaboration. Small misconfigurations – MFA disabled admins, risky sign-ins, over-shared Teams/SharePoint, permissive app consents – create outsized breach risk. InfraSOS turns your tenant telemetry into a dashboard allowing you to track all user activity across all your tenants in 1 dashboard to improve your M365 identity security.

I've been using InfraSOS for about 6 months and we use it daily for running reports on users, especially the password reports. Great tool. This helped us with compliance reports on password polices.

I need to run reports on our Office 365 disabled users to find out who has a license and free up the license for new users. This tool has saved a lot of time and money on O365 licensing. I've scheduled weekly alerts.

Very useful reporting tool. We have several domains and this helped us cleaning up AD before we did an AD migration. The AD Health status was very good to fix isses we had with Active Directory replication status.
