Would you know if your Microsoft 365 security changed today?

Users change. Permissions change. Authentication methods change. Apps get connected. Policies drift. M360 Assurance continuously checks the environment and brings Matthijssen's team in when something needs attention.

01 / THE PROBLEM

Microsoft 365 changes constantly. Security can drift with it.

Users change. Permissions change. Authentication methods change. Apps get connected. Policies and security settings evolve over time.Those changes are normal, but they can also introduce gaps that are easy to miss without continuous visibility.

Would you know if something important changed today?

02 / THE 2026 REALITY

The threat is constant. The weak point is visibility of security drift.

These are 2026 findings from Microsoft and Verizon, not secondary summaries. They show why continuous attention to identity, email, permissions and cloud security configuration matters.

03 / THE SOLUTION

Turn continuous change into a manageable security process.

M360 does not replace Microsoft's security controls. It helps make sure those controls, identities, permissions and configurations continue to receive attention after the initial setup.

01 / BASELINE

Know where you stand.

Measure the tenant against key Microsoft 365 security practices across logging, authentication, email security, administrative privilege and conditional access.

02 / MONITOR

Know what changed.

Re-run the baseline nightly and flag controls that move from pass to fail, plus important identity, access and configuration changes.

03 / REVIEW

Know what matters.

Route alerts to Matthijssen so a technical signal can be reviewed in context instead of becoming another unattended notification.

04 / IMPROVE

Know what comes next.

Track remediation priorities and carry the security roadmap forward so improvements continue over time.

“How do I know our security settings are still right?”

Continuous security posture & drift monitoring

M360 establishes a baseline and then checks it every night so configuration drift does not have to wait for the next quarterly review.

Security baseline scorecard
Nightly pass/fail drift checks
Microsoft Secure Score tracking
Deeper on-demand security scans
Capability-gap analysis for security features already included in Microsoft licensing

“Would we know if an account, permission, or authentication method changed?”

Identity & access visibility

M360 watches the places where access quietly expands or authentication unexpectedly changes.

Authentication-method change monitoring
MFA and passkey adoption tracking
Third-party app and OAuth permission governance
Mailbox delegation and access reviews
Guest accounts and device registrations in on-demand scans

“How do we know if suspicious email or third-party access is creating risk?”

Email protection & incident response

M360 helps verify the protections around your email domain and gives reported or detected suspicious activity a structured investigation path.

SPF, DKIM and DMARC validation
Suspicious inbox and mail-flow rule checks
Phishing triage and evidence-based investigation
Clear escalation when an account appears compromised

“Are we paying for tools and protection we are not using?”

Licensing, reporting & security planning

M360 turns Microsoft 365 administration into something leadership can understand, review and improve over time.

Inactive and over-assigned license review
Quarterly, executive and incident reporting
Remediation tracking
User-access rosters
Security roadmap carried forward quarter to quarter

05 / WHAT M360 ASSURANCE MONITORS

What M360 Assurance monitors across Microsoft 365.

01 Security baseline scorecard +

Measures the tenant against a defined Microsoft 365 security checklist, including audit logging, authentication, email security, administrative privilege and conditional access, then presents the findings in a plain-language scorecard.

02 Nightly drift detection +

Re-runs key baseline checks every night and flags important controls that move from pass to fail so configuration drift can be reviewed before it quietly becomes the new normal.

03 On-demand security scans +

Performs deeper reviews when needed, including checks of guest accounts, device registrations, identity configuration, permissions and other security conditions that may require investigation.

04 Identity & authentication monitoring +

Tracks important identity and authentication changes, including authentication methods, MFA and passkey adoption, administrator access and other account-level security changes.

05 App, OAuth & mailbox governance +

Reviews third-party applications, OAuth permissions, mailbox delegation and access changes so expanding privileges or unexpected access can be identified and reviewed.

06 Email authentication & phishing response +

Checks SPF, DKIM and DMARC configuration, reviews suspicious inbox or mail-flow rules, and provides a structured path for phishing triage, investigation and escalation.

07 Reporting, licensing & roadmap +

Turns findings into ongoing operational and executive reporting, including licensing review, remediation tracking, user-access visibility and a security roadmap that carries priorities forward over time.

HOW IT FITS INTO THE CUSTOMER'S ENVIRONMENT

Continuous Monitoring runs quietly in the background as the Microsoft 365 environment changes.

Human + automation Automation surfaces changes and findings. Matthijssen reviews what needs attention and helps guide the next step.

THE OUTCOME

Know what changed.

Know what matters.

Know what needs attention.

M360 Assurance gives a business an ongoing way to verify that its Microsoft 365 security posture has not quietly drifted away from where it should be.
