[Topic: Overlooked MFA Gaps — When “Enabled” Doesn’t Mean “Enforced”]
Quick Insight:
Many organizations proudly state: “We have MFA enabled.”
But during audits, a different reality often appears — MFA exists, but critical gaps quietly bypass it.
Common MFA blind spots include:
- Legacy protocols (IMAP, POP, SMTP, NTLM) bypassing MFA entirely 🕳️
- Service accounts and API access excluded from MFA 🔑
- “Remember me” sessions lasting weeks or months ⏳
- Conditional access rules applied to users — but not admins ⚠️
- MFA enabled but not enforced for all applications and tenants
⚠️ MFA that can be bypassed is a control — not a defense.
Audit Tip:
🔐 During IAM and access control audits, validate:
- MFA is mandatory, not optional, for all users and admins
- Legacy authentication protocols are fully disabled
- Privileged access requires strong MFA + device trust
- MFA enforcement is consistent across SaaS, VPN, cloud consoles, and APIs
- MFA logs are monitored for fatigue attacks, push bombing, or bypass attempts
Actionable Reminder:
Ask your IAM or identity team:
- Which accounts can still authenticate without MFA?
- Are service and break-glass accounts properly protected and monitored?
- Do conditional access rules cover all sign-in paths, not just the main one?
- Can we prove MFA enforcement — not just configuration?
If MFA can be skipped, attackers will find the skip button before your audit does.
MFA isn’t about checking a box — it’s about closing every door.
