The 8 best best cloud storage for law firms, in detail
Box
Best for: Governed matter files and secure client sharing
Box gives a law firm a central place for pleadings, discovery, contracts and client correspondence, with folder permissions that limit access by matter, team or role. Lawyers can share a link with a client, set an expiry date, and keep the original file in one controlled location instead of sending copies by email. Version history helps a firm recover an earlier draft after an edit, and the admin console shows who opened or changed a file.
- The main trade off is cost and plan structure.
- Business Starter starts at $5 per user per month on annual billing, but it caps a firm at 10 users and gives 100 GB per user, so a growing firm will n
- Firms that need advanced compliance controls, watermarking and device trust will need Enterprise, which costs more again.
Pros
- Unlimited storage on Business plans
- strong admin controls and compliance support
Cons
- Business Starter has a 3 user minimum and a 10 user maximum
- higher plans cost much more than entry storage tools
Dropbox
Best for: Simple sync and sharing for small firms
Dropbox is easy to explain to lawyers, paralegals and clients, and that matters when a firm has limited IT support. Files sync across desktop and mobile, shared folders keep a matter team on the same documents, and links can carry passwords and expiry dates. The Standard plan starts at $15 per user per month on annual billing and starts with 3,000 GB of pooled team storage, with 180 day file recovery.
- That is enough for many small firms that work mainly with Word documents, PDFs and scanned exhibits.
- The limit is control.
- A firm that handles sensitive client data should look closely at Advanced, which starts at $24 per user per month on annual billing and adds single si
- Standard does not include those controls, so a firm that needs a clear audit trail for every file event should budget for Advanced from the start.
Pros
- Fast and familiar file sync across devices
- easy shared folders and link controls
Cons
- Standard lacks single sign-on and audit logs
- Advanced is needed for stronger admin controls
Google Workspace
Best for: Firms built around Gmail and Google Drive
Google Workspace suits a law firm that already uses Gmail and wants storage, email, calendar and video meetings under one login. Google Drive stores matter files in shared drives, where access follows the team rather than one person, so files stay with the firm when a lawyer leaves. Business Starter starts at $7 per user per month on annual billing and includes custom business email, Meet for up to 100 participants and 30 GB of pooled storage per user.
- Business Standard starts at $14 per user per month on annual billing and raises pooled storage to 2 TB per user, while Business Plus starts at $22 and
- A firm should check retention, vault and admin controls at each tier, because basic Drive sharing is not the same as a full matter governance setup.
Pros
- Gmail, Drive, Docs and Meet in one account
- easy sharing inside and outside the firm
Cons
- Business Starter gives only 30 GB of pooled storage per user
- Business plans cap at 300 users
Microsoft 365
Best for: Firms built around Outlook, Word and OneDrive
Microsoft 365 fits most law firms because Word, Outlook and Excel are already part of daily legal work. OneDrive gives each user 1 TB of storage, SharePoint gives team sites for matters and practice groups, and Teams gives chat, calls and meetings in the same account. Business Basic starts at $7 per user per month on annual billing and includes business email, Teams, SharePoint and OneDrive, plus web and mobile versions of the Office apps.
- The trade off is the desktop gap.
- Business Basic does not include desktop Word, Excel or PowerPoint, so a firm that relies on desktop templates, macros or offline drafting will need Bu
- Business Premium at $22 adds advanced threat protection and device management, which can help a firm that handles sensitive client data on laptops and
Pros
- OneDrive and SharePoint inside Microsoft 365
- Word, Excel and Outlook included in the suite
Cons
- Business Basic gives web and mobile apps only, with no desktop Office apps
- full desktop apps need Standard
Egnyte
Best for: Hybrid files and governance for larger firms
Egnyte is built for firms that need more control than a basic sync folder can offer. It supports file locking, versioning, retention policies, sensitive data discovery and ransomware detection, and it can work with files stored in the cloud and on local servers. The pricing page lists plans from $22 per user per month, and the Business plan includes 100 GB of pooled storage, while higher plans include 150 GB.
- Egnyte also supports Microsoft 365 co-editing and Google Workspace editing, so lawyers can edit documents in the apps they know while Egnyte controls
- Higher plans add single sign-on, data residency options and customer managed keys on the top tier.
- Setup takes more time than Dropbox or Google Drive.
Pros
- Strong governance, retention and file locking
- works with cloud and on premises files
Cons
- Entry price is high for a small firm
- storage is pooled at a modest level on lower plans
Tresorit
Best for: End-to-end encryption for sensitive files
Tresorit is a good choice when client confidentiality is the top concern and a firm wants encryption that keeps files unreadable to the storage provider. The Business plan starts at $19 per user per month on annual billing, with a 3 user minimum, 2 TB of storage per user and a 15 GB maximum file size. It includes advanced admin controls, audit logs, custom branding, data residency options and integrations with Microsoft, Google and Okta.
- Business Pro starts at $24 per user per month on annual billing and adds 3 TB per user and dynamic watermarks.
- The main drawback is the storage rule for shared folders.
- A shared folder counts against the storage quota of every user with access, so a firm that shares large discovery sets widely can use up space faster
- Tresorit has fewer office suite features than Google Workspace or Microsoft 365.
Pros
- Zero knowledge end-to-end encryption
- data residency options and detailed audit logs
Cons
- Business needs at least 3 users
- shared folders count against every member storage quota
Sync.com
Best for: Low cost encrypted storage with HIPAA support
Sync.com gives a small law firm encrypted storage at a much lower price than Tresorit or Egnyte. The Teams 1TB plan starts at $6 per user per month on annual billing, with a 3 user minimum, 1 TB of secure storage per user, advanced sharing and an administrator account. It includes end-to-end encryption, SOC 2 Type 1 compliance, HIPAA compliance and GDPR compliance, plus a free plan with 5 GB for a basic test.
- The limit is admin depth on the entry plan.
- Teams 1TB does not include role based access controls or admin delegation, so a firm that needs fine grained roles should move to Teams 2TB, which sta
Pros
- End-to-end encryption on all team plans
- 365 day file history on higher team plans
Cons
- Teams 1TB lacks role based access controls and admin delegation
- no phone support on the entry team plan
How we chose
We checked each vendor pricing page on 2026-11-12 and took the starting price from that page, or from the vendor plan page linked in Sources when the main page used a product selector. We focused on features that matter to a law firm: access controls, audit trails, version history, client sharing, encryption, compliance support and seat minimums. We compared entry plans and the next tier up, because the entry plan often lacks single sign-on, audit logs or e-signatures. We did not claim hands-on testing, and we did not use third party review scores to rank the tools.
Choosing by firm size and budget
| Firm size | Monthly cost at entry price | Best fit from this list |
|---|---|---|
| Solo lawyer, 1 user | $6 to $22, plus seat minimums where they apply | Sync.com, Google Workspace, Microsoft 365 |
| Small firm, 3 users | $18 to $66 per month | Sync.com at $18, Google Workspace at $21, Microsoft 365 at $21 |
| Small firm, 5 users | $30 to $110 per month | Sync.com at $30, Box Starter at $25, ShareFile at $82.50 |
| Mid size firm, 10 users | $60 to $220 per month | Dropbox Standard at $150, Box Business at $150, Egnyte Business at $220 |
| Mid size firm, 25 users | $150 to $550 per month | Microsoft 365 Standard at $350, Google Workspace Standard at $350, Egnyte Business at $550 |
The table uses the entry annual billing price for each tool and multiplies it by the seat count, so a firm can see the real monthly total before it adds tax, add-ons or a higher tier. Seat minimums change the math for a solo lawyer, because Box, ShareFile, Tresorit and Sync.com all need at least 3 users on their team plans. A solo lawyer who wants one of those tools will pay for 3 seats even if only one person uses the account. Google Workspace and Microsoft 365 have no 3 user minimum on their entry business plans, so they are easier to start for a 1 person firm.
Frequently asked questions
What is the best cloud storage for a small law firm?
Google Workspace and Microsoft 365 are strong choices for a small firm because they combine email, storage and office apps in one account at $7 per user per month on annual billing. Sync.com is a good low cost option at $6 per user per month on annual billing if the firm wants encryption and a simple storage service. Pick the tool that fits current email and office apps, then test sharing with a real matter first.
Is cloud storage safe for client files?
Cloud storage can be safe for client files when the firm uses strong access controls, two factor authentication, encryption and audit logs. Limit folder access by matter and role, use passwords and expiry dates on shared links, and keep a clear record of who opened or changed a file. Check the vendor compliance pages and ask for a business associate agreement or a data processing agreement where one is needed for the work.
Do law firms need HIPAA compliance from a storage tool?
A law firm needs HIPAA compliance support when it stores or handles protected health information for a client, such as medical records in a personal injury case. In that case, choose a tool that offers HIPAA support and will sign a business associate agreement. Dropbox Advanced, ShareFile Premium, Tresorit Business and Sync.com team plans all list HIPAA support, but confirm the terms in writing before storing health records in the service.
How much storage does a law firm need?
A law firm needs enough storage for pleadings, discovery, exhibits, scanned documents, email attachments and video files, and that total grows fast with large cases. A small firm can start with 1 TB per user, but a firm with heavy discovery or video evidence may need pooled storage of 3 TB or more for the team. Measure the current file total, add a margin for growth, and check whether shared folders count against each user quota before picking a plan.
Can clients upload files without an account?
Yes, several tools in this list let clients upload files without a full account, usually through a file request link or a client portal. ShareFile and Sync.com both offer that feature, and Dropbox and Box offer shared links and file requests on team plans. Test the upload flow with a client, check the file size limit, and confirm that uploaded files land in the right matter folder with the right access controls.
Should a law firm use a legal specific tool instead?
A legal specific tool can help with matter management, billing and document automation, but it does not replace cloud storage for all files. Many firms use a practice management tool for matters and a cloud storage tool for files, and they link the two where an integration exists. Map the matter workflow first, then choose storage that fits email, office apps and client portal needs, rather than buying a legal tool for storage alone.
