Cyber insurance underwriting has changed dramatically over the past few years. What was once considered a recommended control has now become a baseline expectation. In 2026, multi-factor authentication (MFA) is effectively mandatory for most cyber insurance policies.
But simply having MFA enabled doesn’t cut it. Insurers are increasingly focused on how MFA is implemented, where it is enforced, and whether it truly protects access across the environment. The distinction between “MFA exists” and “MFA is consistently enforced” can be the make-or-break tipping point of underwriting decisions, and even claim outcomes.
The Insurance Problem with Partial MFA
Many organizations deploy MFA gradually. Over time, that can lead to inconsistent enforcement across systems.
It often looks like this:
- MFA required for email but not internal applications
- MFA enforced for employees but not administrators
- Legacy or third-party applications excluded from MFA policies
- Temporary exceptions that quietly become permanent
From an insurer’s perspective, these gaps create unpredictable risk.
If even one application lacks MFA protection, attackers can exploit that entry point to harvest credentials, escalate privileges, and move laterally through the environment. In other words, an organization may technically “have MFA,” but still remain vulnerable.
This is why insurers increasingly treat partial MFA the same as no MFA at all.
What “Insurance-Ready” MFA Looks Like in 2026
Insurers are also paying closer attention to the quality and maturity of MFA implementations.
Basic SMS codes or simple push notifications are increasingly viewed as baseline protections rather than strong defenses. Organizations seeking favorable underwriting outcomes are moving toward more resilient approaches such as:
Phishing-Resistant MFA
Authentication methods such as FIDO2 or hardware-backed security keys prevent attackers from intercepting credentials or hijacking sessions.
Contextual or Adaptive Authentication
Risk-based authentication increases verification requirements when login activity appears suspicious—for example, when a user signs in from a new device or unfamiliar location.
Zero-Exception MFA Policies
Rather than allowing open-ended bypasses, mature organizations replace temporary exceptions with time-bound access controls and centralized visibility.
These approaches demonstrate something insurers care deeply about: that MFA cannot easily be bypassed.
The Enforcement Gap: Where Claims Fail
One of the most common issues uncovered during claim investigations is MFA bypass.
Organizations may believe MFA was enabled, but insurers sometimes discover that access could still occur through a legacy login path or a temporary exception that was never removed. And this risk is far from theoretical.
Between 2024 and 2025, the City of Hamilton faced an $18.4 million recovery bill following a ransomware attack. Its $5 million cyber insurance claim was ultimately denied—not because MFA was absent entirely, but because the city failed to maintain the MFA standards promised in its policy across every department.
For insurers, inconsistent enforcement signals that the control wasn’t fully operational.
As a result, insurers increasingly look for clear evidence that MFA is both implemented and enforced. That often includes:
- Logs showing MFA challenges triggered during authentication sessions
- Evidence that MFA is enforced through the identity layer before reaching applications
- Technical protections against MFA fatigue attacks, such as number matching
Having MFA configured is one thing. Demonstrating that it was active—and unavoidable—at the time of an incident is another.
How Datawiza Strengthens Your MFA Strategy
Datawiza helps organizations close the gaps that often lead to insurance scrutiny or claim disputes by:
- Enforcing MFA Everywhere: Bringing legacy and custom apps into compliance by wrapping them in MFA without requiring a code rewrite.
- Centralizing Policy: Ensuring MFA follows the user, not the application, so there are no “unprotected” corners of your network.
- Automating Asset Readiness: By routing all traffic through a central identity proxy, you gain the visibility needed to satisfy regulations like NYDFS asset inventory requirements.
- Providing Audit Trails: Centralized logs make it easy to demonstrate to both insurers and the meet regulations that your MFA was active and enforced at the time of an incident.
MFA has evolved beyond a basic security control. It now serves as a financial and operational signal of cyber maturity. Organizations that implement comprehensive, unavoidable MFA are better positioned to qualify for coverage, avoid regulatory fines, and lower their overall risk profile.
