What the Proposed 2026 HIPAA Security Rule Overhaul Means for HealthTech Startups

HHS has proposed the first major rewrite of the HIPAA Security Rule in over a decade, and it turns several "nice to have" security practices into hard requirements. Here's what actually changes and what to build before it's final.

What's Actually Changing

For most of the last twenty years, the HIPAA Security Rule has been written in deliberately vague language. Covered entities and business associates were told to use "reasonable and appropriate" safeguards, and left to figure out what that meant on their own. That ambiguity is going away.

The proposed update from the Department of Health and Human Services replaces general guidance with specific, mandatory controls. The draft language calls for multifactor authentication across systems that touch protected health information, encryption of PHI both at rest and in transit, network segmentation so a breach in one system doesn't cascade into every other, regular penetration testing and vulnerability scanning on a fixed schedule, and documented data backup and disaster recovery plans that get tested, not just written and filed away. Real-time monitoring and anomaly detection move from "recommended" to "required."

None of this is exotic. Most mature SaaS companies already do some version of it. What changes is that HHS stops treating these as optional best practices and starts treating them as the floor.

Why This Isn't Just Paperwork This Time

Healthtech founders have heard "big compliance changes are coming" before, and a lot of the time the practical impact was a checklist and a new line in the privacy policy. This is different for two reasons.

First, the specificity removes the wiggle room that let smaller companies defer real investment. "Reasonable and appropriate" let a Series A startup argue that basic access controls were enough for their current size. A rule that names MFA, encryption, and segmentation as explicit requirements doesn't leave that argument available.

Second, enforcement posture has already shifted ahead of the rule itself. OCR audit activity picked up through 2026 even before this proposal, and it lines up with what's happening on the buyer side: hospital systems and enterprise health plans are asking vendors for SOC 2 Type II reports and signed Business Associate Agreements earlier in the sales process than they used to, sometimes before a contract is even on the table. Investors and boards are asking the same questions during diligence. The rule change isn't creating a new expectation so much as it's about to make the existing one legally enforceable.

What to Build Now, Not After the Comment Period Closes

Waiting for the final rule before acting is the wrong call, because most of what's proposed takes months to implement properly, not weeks. A few things are worth prioritizing immediately regardless of how the final language shakes out:

• •Multifactor authentication everywhere PHI is accessible — including internal admin tools and third-party integrations, not just the customer-facing login.
• •Encryption in transit and at rest, verified against every data store and backup, not assumed because "the cloud provider handles it."
• •Network segmentation between systems that touch PHI and everything else, so a compromised marketing site or internal wiki can't become a path into patient data.
• •A tested backup and recovery plan — tested meaning someone actually restores from it on a schedule, not that a backup job runs silently and is never verified.
• •Logging and monitoring that would actually surface unusual access patterns, not just logs that exist for an auditor to skim after the fact.

This is where a lot of healthtech teams run into trouble, because these controls have to be built into the architecture, not bolted onto it. Ontoborn works with healthtech teams specifically on this kind of retrofit — going in after a product was built for speed and rebuilding the access control, encryption, and monitoring layers so they hold up under an actual audit, not just a self-assessment.

Where This Intersects With SOC 2 and HITRUST

If your team already went through a SOC 2 or HITRUST readiness process, the good news is that most of the proposed HIPAA controls overlap heavily with what those frameworks already require. Combined SOC 2 and HITRUST reporting has been gaining traction through 2026 precisely because auditors and buyers got tired of covering the same ground twice, and a lot of the technical evidence — access logs, encryption configuration, incident response documentation — satisfies both. Teams that have already done that work have a real head start. Teams that haven't should treat the HIPAA proposal as the forcing function to start.

Bottom Line

The comment period will run its course and the final rule may soften in places, but the direction is not really in question: healthtech companies will be expected to prove specific technical controls, not just assert good intentions. Building toward MFA, encryption, segmentation, and tested recovery now means the final rule is a compliance exercise instead of an engineering scramble.
