SECURITY AUDIT

Microsoft 365
Security Audit for SMBs

Complete security analysis of your Microsoft 365 tenant. Over 400 checks on identity, email, SharePoint, Teams and compliance.

400+ checks Prowler + ScubaGear CIS + NIST + GDPR Read-only zero impact

The problem: insecure configurations

Most Microsoft 365 tenants have weak security configurations that were never changed from defaults. No sophisticated attacks needed: an account without MFA or an overly permissive sharing policy is enough.

70%

Of tenants don't have MFA enabled for all users, exposing accounts to compromise

65%

Still allow legacy authentication, bypassing modern security protections

55%

Have overly permissive sharing policies on SharePoint and OneDrive

50%

Don't have audit logging enabled, making incident tracking impossible

What we analyze

Six analysis areas to cover the entire attack surface of your Microsoft 365 tenant.

Audit log · Microsoft Purview · Retention policy · eDiscovery · Data classification
Entra ID / Azure AD
Security defaults · PIM · App registrations · Consent policy · Sign-in risk

How it works

From authorization to final report, in four phases.

1

Authorization

Read-only access configuration to your tenant. No changes, no impact. Estimated time: 15 minutes.

2

Automated scan

Prowler M365 and ScubaGear CISA analyze the tenant in parallel. Duration: 2-4 hours, fully automated.

3

Analysis and correlation

Results are correlated, deduplicated and classified by severity and real impact on your environment.

4

Report and remediation

Complete report with executive summary, detailed findings and prioritized remediation plan.

Scanning engines

Two complementary engines for the broadest possible coverage of your Microsoft 365 tenant.

Frequently asked questions

Does the audit impact tenant performance?

No. The audit uses exclusively read-only access via Microsoft Graph API. No changes are made to the tenant, no data is altered, no performance impact for users.

How long does the entire process take?

The automated scan takes 2-4 hours. The complete analysis with report and remediation plan is delivered within 3-5 business days from the scan.

Are recurring audits available?

Yes. We offer quarterly or semi-annual recurring audits to monitor security posture improvement over time and detect new risky configurations.

Does it work with all Microsoft 365 plans?

Yes. The audit works with all plans: Business Basic, Business Standard, Business Premium, E3, E5. Some advanced features (PIM, Defender) are only available with premium licenses.

Do you provide remediation support?

Yes. Every finding includes step-by-step remediation instructions. We also offer an assisted remediation service where our team implements the fixes directly on your tenant.
