A fast self-check for business owners and operations teams who want a clearer picture of Microsoft 365 risk before a phishing incident, insurance question, or suspicious mailbox event forces the issue.
Free PDF self-check • MFA, admins, mailboxes, and sharing • Built for owner-language review
Use this self-check to review the settings and risk areas that most often create avoidable email and account exposure in Microsoft 365.
Review each area honestly. The goal is not to pretend the tenant is secure. The goal is to identify where MFA, admin access, forwarding behavior, sharing, and mailbox hygiene still need work.
Guide overview
The self-check focuses on the areas that most often lead to account takeover, phishing fallout, mailbox compromise, and insurer or leadership concern in Microsoft 365 environments.
Preparation
Microsoft 365 problems often stay invisible until an attacker, broker, or executive asks the wrong question at the wrong time. A short review now is cheaper than cleaning up the wrong assumption later.
Find the most common Microsoft 365 security blind spots faster.
Separate true controls from vague assumptions.
Create a clearer case for what needs review or remediation next.
