The best HIPAA-compliant cloud storage is not a single product, it is any storage that clears the right checks and is configured correctly. Here is how to choose, and what the major clouds offer.
TL;DR
There is no storage product that is HIPAA-compliant on its own. Compliant storage means a provider that signs a BAA, strong encryption, access control with logging, and correct configuration by you. The major clouds, AWS, Azure, and Google Cloud, all offer HIPAA-eligible storage under a BAA.
Choose by evaluating the provider against a clear checklist rather than a ranking, and remember that only the specific services named in the BAA are covered. How you configure and protect the data matters as much as which provider you pick.

Why there is no single “best” HIPAA storage
Search for the best HIPAA-compliant cloud storage and you will find ranked lists of products. The honest answer is more useful: no storage service is compliant by itself. A provider can be HIPAA-eligible, meaning it will sign a business associate agreement and has built safeguards into its infrastructure, but whether your stored PHI is actually protected depends on how you configure and use it. The right question is not “which product tops the list” but “which provider clears the checks, and can I run it correctly.”
What HIPAA-compliant storage actually needs
Regardless of vendor, compliant storage rests on the same foundations.
A provider that will sign a BAA, encryption of data at rest and in transit, and access control with audit logging are the non-negotiables. Any storage that cannot offer all three is not a candidate for PHI, no matter how it markets itself.
The evaluation checklist
Instead of trusting a ranking, run every candidate through the same questions. If it clears these, it is a viable option; if it does not, move on.
Note the two easily-missed checks: whether the specific storage service is named in the BAA, since a BAA covers particular services, not the whole platform, and whether your backups are protected to the same standard, because backups of PHI are still PHI.
What the major clouds offer
Because they come up in every search, it is worth stating the factual baseline: the three major cloud platforms are all HIPAA-eligible and will enter into a BAA.
| Provider | HIPAA-eligible storage | BAA |
|---|---|---|
| AWS | Yes, for covered services | Offered |
| Microsoft Azure | Yes, for covered services | Offered |
| Google Cloud | Yes, for covered services | Offered |
Your part in it
On any of these platforms, the same responsibilities fall to you: enable encryption and manage keys, apply least-privilege access with MFA, turn on and review audit logging, keep PHI inside BAA-covered services, and prevent public exposure of storage buckets and databases. This is where the overwhelming majority of storage breaches happen, not in the provider’s infrastructure, but in customer configuration.
The lean-team path to compliant storage
The provider gives you a BAA and secure infrastructure. It does not tell you whether your storage is encrypted correctly, exposed publicly, or accessed only by the right people, and it will not assemble the evidence an auditor wants. Watching that across accounts and services is exactly where lean teams struggle with disconnected tools.
Store PHI on any major cloud, correctly.
Osto is the one-stop cybersecurity and compliance platform built for fast-moving startups. Keep your cloud storage encrypted, access-controlled, and provably configured across AWS, Azure, and GCP on one platform mapped to HIPAA. No security team required.
Frequently asked questions
What is the best HIPAA-compliant cloud storage?
There is no single best product. The best choice is any HIPAA-eligible storage, one whose provider signs a BAA and secures the infrastructure, that you can configure correctly with encryption, access control, and logging. AWS, Azure, and Google Cloud all offer HIPAA-eligible storage.
Is Google Drive or Dropbox HIPAA compliant?
Only if the provider will sign a BAA covering your use and you configure it correctly. Consumer file-sharing tools are generally not appropriate for PHI unless a business-tier, HIPAA-eligible configuration with a signed BAA is in place. Always verify the BAA and settings.
Do AWS, Azure, and GCP offer HIPAA-compliant storage?
Yes. All three are HIPAA-eligible and will sign a BAA, but only for specific covered services. PHI must be kept within those covered services, and you remain responsible for encryption, access, and configuration.
Does a BAA make my storage compliant?
No, it is necessary but not sufficient. A BAA covers the provider’s responsibilities, but your compliance also depends on encryption, access control, logging, and correct configuration. Most storage breaches come from customer-side misconfiguration, not the provider.
Are backups of PHI also covered by HIPAA?
Yes. Backups of protected health information are still PHI and must be protected to the same standard, encrypted, access-controlled, and covered by the BAA. Overlooking backups is a common gap in otherwise careful storage setups.
How do I evaluate a storage provider for HIPAA?
Run it through a checklist: will it sign a BAA, is data encrypted at rest and in transit, are access control and logging available, is the specific storage service BAA-covered, are backups protected, and can you produce an audit trail. If it clears these, it is a viable option.
