PRODUCT FEATURE

Microsoft 365 Security

Holm Security continuously assesses your Microsoft 365 tenant against the CISA SCuBA baseline, the U.S. federal security standard for Microsoft 365. We identify misconfigurations across identity, email, collaboration, and data protection, and map each finding to clear remediation guidance so you can fix what matters before cybercriminals exploit it.

What we cover

Microsoft 365 coverage mapped to the CISA SCuBA baseline

Identity & access

We assess MFA enforcement, Conditional Access policies, privileged identity management alerting, guest access controls, and dormant admin accounts.

Email security

We assess DKIM and DMARC enforcement, anti-phishing policies, anti-malware configuration, mail flow rules, and external forwarding settings.

Collaboration

We assess external access, meeting policies, app permissions, and the federation settings that let cybercriminals move between organizations.

Threat protection

We assess Safe Links, Safe Attachments, audit logging, and the alert routing that determines how fast your team can respond.

Data protection

We assess external sharing defaults, Anyone links, link expiration, and guest re-authentication across SharePoint Online.

WHY IT MATTERS

Reduce your Microsoft 365 attack surface

  • Harden your Microsoft 365 tenant before cybercriminals exploit default settings built for ease, not security.
  • Replace manual reviews and one-off audits with continuous, scheduled assessments inside the platform you already use.
  • Build a systematic, repeatable cybersecurity approach as required by NIS2 and DORA.
  • Prove your Microsoft 365 baseline holds over time, with severity-based prioritization, remediation guidance, and reporting built in.
  • Get an independent view alongside Microsoft Secure Score, measured against the CISA SCuBA federal baseline instead of vendor-only recommendations.

Frequently asked questions

Why does Microsoft 365 security assessment matter?

Microsoft 365 controls where your identity, email, and collaboration data live, which makes tenant configuration a primary target. Cybercriminals exploit misconfigurations like disabled DMARC enforcement, oversharing in SharePoint, and legacy authentication to gain access and move through your environment. Holm Security's Microsoft 365 security assessment continuously checks over 100 controls against the CISA SCuBA federal baseline so you can close those gaps before they are exploited.

How is this different from Microsoft Secure Score?

Microsoft Secure Score reflects Microsoft's own recommendations for its own product. Holm Security's assessment measures your tenant against CISA SCuBA, an independent standard published by the U.S. Cybersecurity and Infrastructure Security Agency. The two are designed to complement each other, giving you both Microsoft's view and an independent one.

How is this different from real-time threat detection?

Microsoft 365 security assessment checks your configuration on a schedule, not your live traffic. It tells you where your tenant is exposed by design, such as a missing DMARC policy or an overly permissive sharing default, rather than detecting an attack as it happens. Think of it as fixing the locks, not watching the security camera.
