Why you Shouldn’t bypass MFA for your office IP adresses

This article discusses the common but risky practice of bypassing Multi-Factor Authentication (MFA) for office IP addresses, particularly in high-turnover environments like education. It highlights how Source Network Address Translation (SNAT) can cause guest networks and corporate networks to share the same external IP, allowing attackers on guest Wi-Fi to bypass MFA. The article also clarifies misconceptions about MFA user friction, explaining how Primary Refresh Tokens (PRT) enable seamless Single Sign-On without repeated prompts. It recommends adopting a zero trust mindset, auditing Conditional Access policies, and removing network exclusions that bypass MFA to enhance security.
