Microsoft 365 Security Assessment

It’s a structured evaluation of your Microsoft 365 environment against security best practices. The result: a clear snapshot of your current state and a plan to fix misconfigurations, reduce risk, and harden your defenses.

You should run a Microsoft 365 Security Assessment if you suspect misconfigurations, are preparing for audits or compliance requirements, or want to ensure you’re fully using the security features included in your environment.

The security controls reviewed as part of the Microsoft 365 Security Risk Assessment are a combination of ProArch’s do-first controls, Microsoft 365 Security Best Practices, and industry-standard best practices.

We evaluate identity, access, email, configuration, and behavioral security controls, including:

• Multi-Factor Authentication (MFA)
• Global Admin Configuration
• Mailbox Security
• Audit Logging
• Suspicious Sign-In Alerts
• Application Permissions
• Mail Flow Rules
• …and more.

A 10+ page report outlining:

• Your current security posture
• Misconfiguration and risk findings
• Prioritized remediation actions

We’ll walk you through the findings so you know exactly where to focus.

Secure Score is an automated Microsoft tool that provides a list of recommended security improvements and a numerical score based on best practices.

ProArch’s M365 Security Assessment has security experts validate your configurations, identify real misconfigurations, and prioritize findings by real risk so you know exactly what to fix and in what order, not just how to improve a score.

The Microsoft 365 Security Review typically takes 2-3 weeks and starts at $6,000. Final cost depends on scope and environment complexity.

A Microsoft 365 Security Review is similar to an Office 365 security audit, but it goes further. While an audit typically focuses on identifying gaps or compliance issues, the review includes expert validation of your configurations, prioritizes findings based on real risk, and provides a clear, actionable plan to improve your security posture.
