MFA, Encryption, Immutable Backups: The Big Three for 2026

Ask a cyber insurance underwriter, an OCR investigator, and a ransomware negotiator what separates a practice that recovers quickly from one that doesn’t, and you’ll get the same three answers: multi-factor authentication, encryption, and immutable backups. None of these are new ideas. What’s changed is that they’re no longer optional extras — they’re becoming the baseline every covered entity is expected to meet, formally or not.

Multi-Factor Authentication

MFA requires a second proof of identity beyond a password — a code, an app confirmation, a hardware key — before granting access to a system. It sounds simple, and it is, which is exactly why it’s so effective: it blocks the large majority of credential-based attacks, the most common way ransomware and unauthorized access incidents start. The gap for most dental groups isn’t whether MFA exists somewhere in the organization — it’s whether it’s enforced consistently across every system, at every location, for every user, including administrative accounts that often get overlooked.

Encryption at Rest and in Transit

Encryption protects data both while it’s stored and while it’s moving between systems, so that even if a device is lost or traffic is intercepted, the underlying patient data isn’t readable without the decryption key. The proposed 2026 HIPAA Security Rule would make encryption mandatory rather than an optional “addressable” safeguard, closing off the long-standing argument that a smaller practice could reasonably skip it.

Immutable Backups

An immutable backup can’t be altered or deleted once written — not even by an attacker who has already compromised your network with administrator-level access. That distinction matters because modern ransomware routinely targets backup systems specifically, on the assumption that a practice with no clean backup to restore from is far more likely to pay. A backup that ransomware can encrypt right alongside your live data isn’t much of a backup.

Consistency Is the Real Challenge

None of these three controls are difficult to implement at a single location. The difficulty is keeping them consistently enforced across every location in a growing group, especially ones added through acquisition that may have arrived with their own IT setup, their own vendor relationships, and their own gaps.

Effex’s Compliance Management module gives you one place to track which safeguards are actually in place at each location, so “we have MFA” is a verified fact rather than an assumption.
