MFA for Business: Benefits, Methods & Why It Still Matters

This article provides a practitioner-oriented overview of multi-factor authentication (MFA), outlining its security benefits, common adoption challenges, and the threat landscape targeting MFA. It summarizes attacker techniques such as SIM swapping, social engineering/push bombing, Adversary-in-the-Middle (AiTM) with Evilginx, brute-force against exposed services, token theft, and attempts to disable MFA post-compromise, while citing recent high-profile incidents tied to missing MFA. The piece concludes with practical guidance on choosing and deploying MFA options (app-based, hardware tokens, biometrics) and emphasizes pairing MFA with managed identity and endpoint detection capabilities.
