Facts & Expert Analysis:
- The increased use of cloud computing in healthcare means there is a rising need for HIPAA-compliant cloud storage services, but finding the right one can be tricky.
- Sync.com is the best HIPAA-compliant cloud service, offering a triple threat of zero-knowledge encryption, access control and a low price point.
- Google Drive, OneDrive and Dropbox all technically offer HIPAA compliance, though their history of mishandling user data means you’d be wise to stay away from them.
Healthcare workers spend a lot of time handling sensitive patient data. However, storing that data locally on physical computers isn’t always the smartest choice, especially with the onslaught of ransomware attacks that can cripple a healthcare institution. If you’re a healthcare professional, backing up your organization’s data to a HIPAA-compliant cloud storage service is a must.
HIPAA (or the Health Insurance Portability and Accountability Act of 1996) is a law that regulates how healthcare organizations handle their patients’ data, ensuring doctor-patient confidentiality. However, cloud services very rarely offer the level of security and privacy needed to keep such sensitive data safe.
In this article, we’ll list several HIPAA-compliant cloud storage services and explain what it takes to comply with HIPAA. Our top pick is the ultra-secure Sync.com for Teams, which offers zero-knowledge encryption and advanced user management features. We’ll also shed light on a few cloud services to avoid, so be sure to stick around.

HIPAA regulations demand strict protection of patient health information, but many cloud providers offering Business Associate Agreements still lack the zero-knowledge encryption necessary to truly safeguard sensitive medical data. While some service providers technically meet compliance requirements, their data collection practices and server-side encryption create unnecessary privacy risks for healthcare organizations.

What Makes the Best HIPAA-Compliant Cloud Storage?
The Best HIPAA-compliant cloud storage needs to meet encryption standards and have the correct policies and procedures for data access management.
What Is Protected Health Information (PHI)?
The term “protected health information,” or PHI, refers to patient data that’s covered by HIPAA. This could include your medical history or prescriptions, as well as personally identifying data, like your ethnicity, gender and birthday.
A HIPAA-covered entity must make sure that this data isn’t disclosed to anyone other than the patient, except for when it needs to be disclosed to provide patient care. In electronic form, this data is referred to as “electronic protected health information,” or ePHI.
HIPAA-covered entities and business associates must follow strict rules regarding the handling of this data. A storage service must provide encryption and protection for PHI while it’s in transit, as well as when it’s on its servers (known as end-to-end encryption). It must also provide strict control and overview of who can access it and provide detailed logs of access attempts.
What Is a Business Associate Agreement (BAA)?
A business associate agreement (BAA) is a document that regulates the relationship between the cloud operator and the healthcare organization. This is a required provision that anyone handling patient information and medical data must have in place.
This is because HIPAA compliance relies on the proper implementation of the cloud service by its user. The cloud service must provide the means to do so, but the BAA ensures both sides know their responsibilities.
The 7 Best HIPAA Cloud Storage Services
These seven services provide the best provisions for HIPAA compliance, allowing you to fully embrace every HIPAA rule. Let’s dive into our number-one choice: Sync.com for Teams.
1. Sync.com for Teams
Sync.com is our favorite cloud storage service overall, and its business version — Sync.com for Teams — tops this list too. We’ve long touted its outstanding security, driven by zero-knowledge encryption. It’s based in Canada, which means that it’s beholden to PIPEDA, a Canadian law protecting data privacy that includes health information.
The service offers control over user permissions, which lets you control who is able to see PHI. It also gives administrators oversight over user activity, including activity logs.
To add to all of this, Sync.com offers some of the best deals in cloud storage, and even offers plans with unlimited cloud storage. You can read our full Sync.com for Teams review for more details or sign up for its 5GB free plan.

2. Tresorit
Tresorit offers zero-knowledge encryption for all users and the option to sign a BAA on the Business and Enterprise plans. It includes a secure file sharing feature that allows employees to share documents without them being put at risk. Admins can then manage who users can share documents with and manage active sharing links, to reduce the risk of data breeches.
Enterprise users are also able to manage Tresorit accounts through an api to connect Tresorit to third-party services, such as Microsoft Azure. This is alongside Tresorit’s range of plug-ins for other Microsoft and Google software.
Tresorit isn’t the cheapest, with the 2TB Business plan costing $33.99 per month per user, or $27.49 per month on an annual plan. However, it offers a 14-day free trial and Enterprise plans from just 30 users. Read our Tresorit review to learn more.

3. Proton Drive
![Video thumbnail for the video: I Tested Proton Drive to See If It's as Private as It Claims [2024 REVIEW]](https://img.youtube.com/vi/XWmsFdm-VLg/maxresdefault.jpg)
Proton Drive is a privacy-first cloud storage service from the makers of Proton Mail, offering zero-knowledge encryption and Swiss jurisdiction. In our stress tests, it handled large file loads with ease, uploading files in alphabetical order with smooth folder navigation and no hangs or errors.
For collaboration, Proton Drive now features integrated Proton Docs and Sheets, allowing teams to edit documents simultaneously with zero-knowledge protection. Our sync testing showed no conflicts during simultaneous edits, with the service correctly registering duplicate uploads without version history clutter.
but its sharing options need work for strict HIPAA access control.
However, HIPAA-conscious organizations should note that Proton Drive only offers basic “editor” or “viewer” for sharing permissions. While it supports link expiry dates, the absence of granular access controls is a notable drawback for healthcare workflows requiring strict PHI protection. Read our Proton Drive review for more.

4. Internxt
Internxt is an open-source cloud storage service that offers zero-knowledge encryption at one of the most competitive price points in the market. For HIPAA compliance, it includes both password protection and expiry dates for shared links, giving healthcare organizations the access controls needed to protect PHI.
The service features client-side encryption, ensuring that Internxt cannot access your files on its servers. This makes it a strong option for smaller healthcare practices looking for affordable, privacy-focused storage without the premium price tag of enterprise solutions.
However, organizations handling large volumes of medical records should be aware of some limitations. Our stress tests found that the desktop app struggles with large files and ZIP archives, occasionally causing sync delays. Check out our Internxt review for all the details.

5. Box Business
Box Business is an excellent business cloud service provider and another juggernaut in the enterprise cloud storage sphere. And, like the other services on this list, is very secure. Unfortunately, client-side encryption requires an additional purchase, and you can’t even get it on the cheapest plan.
That said, Box is HIPAA compliant and offers advanced user control and activity oversight. Its privacy policy states that it collects quite a large amount of data from its users, but fortunately, it’s nothing that could compromise the privacy of patients’ healthcare data. It also has two-factor authentication for people outside the organization.
but client-side encryption is a separate purchase.
Box Business isn’t cheap, though all of its plans come with unlimited storage to make up for it. Despite the price, it’s still a solid service, deserving of the third spot. Check out our Box Business review or sign up for a 14-day free trial.

6. Egnyte Connect
The sixth place on this list goes to Egnyte Connect. It’s a stellar business cloud storage solution, and it offers excellent security too. Egnyte Connect has user-management features galore, and it even has intelligent data lifecycle management features.
All of Egnyte’s plans are HIPAA compliant, although only its Enterprise plan carries zero-knowledge encryption. Still, that doesn’t mean Egnyte isn’t secure. In fact, it’s one of the most secure EFSS services we’ve tested. It also offers single sign-on (SSO) to make user management easier.
Egnyte isn’t the cheapest, with its 1TB plan being more than twice as expensive as Sync.com’s. Because of this and the lack of client-side encryption on cheaper plans, Egnyte only manages to hit second place on this list. Read our full Egnyte review for more, or take advantage of its 15-day free trial.

7. IDrive for Business
IDrive for Business isn’t a cloud storage service per se, focusing on online backup instead. It comes with cloud storage and sync capabilities, and it can be used in a HIPAA-compliant manner, offering a BAA for interested parties.
When it comes to backup, IDrive offers a ton of functionality, and it also offers user and access management features for the purposes of HIPAA. When it comes to PHI privacy, we have no complaints, as it comes with zero-knowledge encryption out of the box.
In terms of pricing, IDrive is relatively cheap for the storage it offers, although Sync.com still provides more value with its unlimited plan. If you need its backup capabilities, IDrive is a worthy service, but because cloud storage is its secondary function, we’ve relegated it to fourth place.

Other Services That Offer a Business Associate Agreement
Although some cloud services can be used in compliance with HIPAA and let you sign a BAA with them, we still do not recommend using them if they don’t offer zero-knowledge encryption.
Zero-knowledge encryption (or client-side encryption) means that your organization is the only one with access to its encryption keys.
If a service is able to decrypt your files, then it can access them despite a signed BAA. This includes disclosing user data to law enforcement under a court subpoena, which can include your patients’ PHI. The following services let you sign a BAA, but don’t offer client-side encryption.
1. Microsoft OneDrive
OneDrive offers HIPAA compliance to businesses and lets you sign a BAA, but it’s not without its issues. It only recently adopted encryption for its cloud storage (an absolutely basic security feature), which is telling of Microsoft’s attitude toward privacy. Not only that, but the service is not zero-knowledge and Microsoft is known for harvesting user data, much like the next service on this list.
2. Google Drive
Google’s cloud storage also offers HIPAA compliance via its Google Workspace suite, but has the same issue as OneDrive. Although Google Drive has always had encryption, it doesn’t offer client-side encryption and it scans every file you upload to it for viruses and copyrighted content. So, although it technically could be considered HIPAA compliant, we still wouldn’t recommend it for storing PHI.
3. Dropbox Business
![Video thumbnail for the video: Should You Still Use Dropbox in 2024? [Updated Review]](https://img.youtube.com/vi/bwy8HZ1Uvnk/maxresdefault.jpg)
Following the same pattern as the previous two (though to a lesser degree) is Dropbox Business. It’s willing to sign a BAA with healthcare providers, but doesn’t offer zero-knowledge encryption. Learn more in our ‘Is Dropbox HIPAA-compliant‘ guide.
While it’s not in the marketing business like Microsoft and Google are, it’s been in hot water before for numerous data leaks, including one from 2018 where it willingly gave user data to a third party.
Final Thoughts
That’s it for our countdown of the best HIPAA-compliant cloud storage services. We hope you found it useful. Sync.com came out on top, offering zero-knowledge encryption and unlimited storage at a bargain-bin price.
