🔑 Good news: Microsoft 365 Business Premium already includes Entra ID P1 — enough to enforce phishing-resistant MFA. Your cost is primarily labor, not new licensing.
How is this estimated?

This model combines your high-value account count, a per-account annual likelihood of a successful adversary-in-the-middle (AiTM) compromise that varies by MFA posture, and a per-incident loss based on your typical wire size plus a fixed remediation allowance. Phishing-resistant (FIDO2) authentication is modeled at the Stage 5 likelihood. Corsica clients with phishing-resistant MFA in place typically see fewer than five BEC incidents per year. Figures are directional estimates for discussion, not a quote or a guarantee.
