Law firms handling sensitive client data like protected health information (PHI) must comply with HIPAA regulations. Non-compliance can lead to hefty fines, damaged client relationships, and reputational harm. To meet HIPAA requirements, law firms need secure cloud storage solutions that encrypt data, control access, and enable staff training.
Here are the 7 best HIPAA-compliant cloud storage providers for law firms:
- Microsoft OneDrive: Integrates with Microsoft 365, offers encryption, two-factor authentication, custom domains, and scalable storage.
- Amazon AWS: Provides secure storage options like Amazon S3 and Amazon EFS, scalability, flexibility, encryption, access controls, and audit logs.
- Dropbox Business: Offers file sharing, backup, SSL encryption, access controls, two-factor authentication, and single sign-on.
- Google Drive: Works with Google apps, provides affordable storage, file sharing, backup, encryption, access controls, and two-factor authentication.
- Box: Offers unlimited storage, app integrations, end-to-end encryption, custom permissions, access controls, and audit trails.
- Sync.com: Provides encryption, sharing options, file versioning, custom branding, zero-knowledge encryption, access controls, and audit trails.
- IDrive: Offers online backup, cloud storage, multi-device backup, versioning, encryption, access controls, and audit trails.
| Provider | Key Features | HIPAA Compliance | Entry-Level Pricing |
|---|---|---|---|
| Microsoft OneDrive | File sharing, collaboration, encryption, access controls | BAA, encryption, access controls, audit logs | Microsoft 365 Business Basic $7/user/month, paid yearly |
| Amazon AWS | Secure storage, scalability, flexibility | Encryption, access controls, audit logs | Usage-based: per GB stored, per request, per GB transferred |
| Dropbox Business | File sharing, backup, SSL encryption | Access controls, two-factor authentication, SSO | Standard $15/user/month, 3 TB for the team |
| Google Drive | File sharing, collaboration, encryption, access controls | BAA, encryption, access controls, two-factor authentication | Per user/month through Google Workspace; see Google’s calculator |
| Box | Unlimited storage, app integrations, end-to-end encryption | BAA, encryption, access controls, audit trails | Business $15/user/month billed annually, 3-user minimum |
| Sync.com | Encryption, sharing, versioning, custom branding | Zero-knowledge encryption, BAA, access controls, audit trails | Teams 1TB $8/user/month, or $6 billed annually, 3-user minimum |
| IDrive | Online backup, cloud storage, multi-device backup | Encryption, access controls, audit trails | Personal 5 TB $119.88/year |
Prices were checked against each provider’s own pricing page at the time of writing and change often, so confirm the current rate before you commit. Watch the unit: Microsoft, Dropbox, Google, Box and Sync.com all charge per user per month, several with a minimum number of users and a lower rate if you pay for a year up front. AWS charges for what you use rather than for seats. IDrive charges per year for a pool of storage.
One thing matters more than any of these prices. A BAA is normally attached to a provider’s business or enterprise agreement, not to a consumer subscription, so a cheap personal plan is the wrong thing to buy for PHI even where the underlying service is the same. Get the BAA in writing before you upload anything.
When choosing a HIPAA-compliant cloud storage provider, consider security and compliance, data storage and retrieval, collaboration and sharing, and pricing and scalability.

About OneDrive
OneDrive is Microsoft’s cloud storage service. It allows law firms to store and manage client data securely, including protected health information (PHI). OneDrive meets HIPAA compliance requirements, making it a trusted option for handling sensitive data.
Key Features
OneDrive offers several useful features for law firms:
- Microsoft 365 Integration: Seamless collaboration and document management within the Microsoft ecosystem.
- Security: Encryption, two-factor authentication, and other measures to protect data.
- Custom Domains: Law firms can use their own domain names.
- Scalable Storage: Increase storage capacity as needed.
HIPAA Compliance

Microsoft provides a Business Associate Agreement (BAA) outlining responsibilities for protecting PHI. OneDrive includes:
- Encryption for data in transit and at rest
- Access controls and authentication
- Audit logs and reporting
Pricing Plans
| Plan | OneDrive storage | Price per user, per month |
|---|---|---|
| Microsoft 365 Business Basic | 1 TB per user | $7.00, paid yearly |
| Microsoft 365 Business Standard | 1 TB per user | Higher; see Microsoft’s current rate |
| Enterprise | Custom | Custom |
Buy the business subscription, not the consumer one. Microsoft 365 Personal and Family are cheaper per terabyte, but the HIPAA BAA sits under the business and enterprise agreements. The annual commitment is what the headline price assumes; month-to-month costs more.
Pros and Cons
| Pros | Cons |
|---|---|
| Microsoft 365 integration | Limited customization |
| Strong security features | Learning curve for non-Microsoft users |
| Scalable storage | Limited support for non-Windows devices |

2. Amazon AWS

About Amazon AWS
Amazon Web Services (AWS) is a cloud computing platform from Amazon. It offers storage, computing, databases, analytics, and more. Law firms choose AWS for its scalability, flexibility, and strong security.
Key Features
AWS provides key features for law firms:
- Secure Storage: Options like Amazon S3, Amazon EBS, and Amazon Elastic File System (EFS) to store sensitive data securely.
- Scalability: Law firms can increase or decrease storage and computing resources as needed.
- Flexibility: AWS can be customized to meet specific needs, supporting various operating systems, programming languages, and applications.
HIPAA Compliance
AWS is HIPAA-compliant and offers features to support compliance:

- Access Controls: Identity and access management (IAM) controls who can access sensitive data.
- Audit Logs: Detailed logs track access and activity for monitoring and reporting compliance.
Pricing Plans
AWS uses a pay-as-you-go model, so law firms only pay for the resources they use. Pricing varies based on the specific services and resources used.
| Service | How it is charged |
|---|---|
| Amazon S3 | Per GB stored per month, by storage class, plus requests and retrieval |
| Amazon EBS | Per GB provisioned per month, by volume type |
| Data transfer | Per GB out of AWS; transfer in is generally free |
We are not quoting per-GB rates here. AWS rates differ by region and storage class and are revised regularly, and a figure copied into an article goes stale quietly. Use the AWS pricing calculator with your own region and volume. Two costs catch firms out: requests and retrieval on the colder storage classes, and data transfer out when you move everything to another provider. Note also that AWS gives you the raw storage, not a document system, so budget for the work of building and running one.
Pros and Cons
| Pros | Cons |
|---|---|
| Scalable and flexible | Steep learning curve for non-technical users |
| Strong security features | Can be complex to manage and optimize |
| Wide range of services and resources | Pricing can be unpredictable and variable |
| Supports various operating systems and applications |

| Enterprise | 5 TB, more on request | Contact sales |
We have left the figures out on purpose. Google shows Workspace pricing through a calculator that moves with your user count and with whether you commit for a year or stay flexible, so any single number quoted here would be wrong for most readers. Get your own quote from Google’s pricing page. Storage is pooled across the organisation rather than locked to each seat.
Pros and Cons
| Pros | Cons |
|---|---|
| Easy file sharing and collaboration | Limited customization options |
