10 Best Cloud Storage for Business of 2026

OneDrive for Business ranks first because it gives the most storage and admin control per dollar for companies that already run on Microsoft. Business Basic costs $7.00 per user per month paid yearly and includes 1 TB of cloud storage per user, SharePoint team sites for shared department files, Teams for chat and meetings, custom business email and web and mobile versions of Word, Excel, PowerPoint and Outlook. Admins manage identity and access for up to 300 users from one console, and Business Premium adds advanced security for teams that need device and data protection. Co-editing Office files is where it feels most natural, since the files live next to the apps. The trade-offs are structure and scale: business plans stop at 300 users, Business Basic has no desktop Office apps, and new admins have to learn where OneDrive settings end and SharePoint settings begin. Teams outside the Microsoft ecosystem will get more from a standalone tool.

Dropbox remains the easiest business storage to roll out, and its plans now cover most of what a team needs to share work with clients. Standard starts at 3 TB for the whole team and works for a single user, with team folders, groups and roles, password protected shares, branded file links, PDF editing and signatures, plus transfers of files up to 100 GB. Deleted files can be restored for 180 days. Advanced raises pooled storage to 15 TB, keeps a year of history and adds the controls larger companies ask for: tiered admin management, end-to-end encryption, advanced key management, compliance tracking and single sign-on. Enterprise lifts transfers to 250 GB and adds integrations with security tools and dedicated support. The weak spot for admins is that SSO and tiered roles sit on Advanced, which needs 3 or more people. We could not confirm a USD price from our location, so check the vendor page.

Google Drive is the natural choice for companies that already write in Docs and Sheets, since files are edited in place by many people at once instead of being downloaded and re-uploaded. Storage is pooled across the organization, so a plan with 2 TB per user on Business Standard or 5 TB on Business Plus is shared by the whole team, and light users leave room for heavy ones. Every plan includes custom business email, and Gemini is available in Gmail on Starter and across Docs, Meet and more from Standard. Business Plus adds eDiscovery for legal and compliance holds, and Enterprise adds S/MIME encryption. The entry plan is the catch for file heavy teams: Business Starter includes only 30 GB per user, so most companies storing real archives will need Standard. Google also showed us local currency prices, so we could not confirm a USD figure and list pricing as pending.

Box is the most complete content platform here for companies with heavy compliance and admin needs. Every business plan includes unlimited storage, integrated Box AI, unlimited e-sign requests, over 1,500 integrations and SOC 1/2/3 compliance support. Business allows 5GB uploads and charges for each external collaborator, Business Plus adds unlimited external collaborators, 15GB uploads and advanced admin controls, and Enterprise brings 50GB uploads, Box Hubs content portals, advanced workflows and security, plus FedRAMP Moderate and HIPAA support. Enterprise Plus adds threat detection and 24 hour support. That range makes Box a strong pick for regulated industries and for companies that share heavily with partners. It is less friendly for very small teams: plans need at least 3 users, the cheapest tier limits external sharing, and many admin features only appear on Business Plus. Box showed us euro prices, so its USD pricing is pending.

Sync.com is the value pick for small teams that care about privacy. Its Teams 1TB plan costs $6 per user per month billed annually, or $4.50 during a first year discount, and includes 1 TB of end-to-end encrypted storage per user, advanced sharing, an administrator account and unlimited data transfer. Teams 2TB adds role-based access control, admin delegation and custom branding, and Teams 10TB adds VIP support. End-to-end encryption means only your team holds the keys to file contents, which suits law, accounting and healthcare offices. Sync also lets you restore previous versions and deleted files for 180 days on the entry plan and 365 days above it. The limits are scope and ecosystem: plans need 3 users, the entry tier has no role-based access, and there is far less office editing and third party integration than Microsoft, Google or Dropbox offer. Enterprise plans start at 100 users.

Proton Drive brings the encryption approach of Proton Mail to business file storage. Drive Professional costs $7.99 per user per month billed yearly and includes 1 TB per user, end-to-end encryption that covers metadata, sharing by link or email with access control, and 365 days of version history. Admins get a business admin panel, can delegate admin permissions, enforce two-factor authentication, sign in as a user and protect data with an organization key. Proton Docs and Sheets let teams edit documents in real time without giving up encryption, and a command line tool handles scripted backups. Workspace Standard at $12.99 adds encrypted mail, calendars, video meetings, a VPN and a password manager with shared vaults. The limits are reach and integrations: there are fewer connectors to other business apps than in Box or Dropbox, and the strongest collaboration features depend on moving more of your work into Proton.

Egnyte is built for companies where who can see a file matters as much as where it is stored. The Business plan at $22 per user per month paid annually includes discretionary permissions with flexible inheritance, email-validated sharing, versioning with global file locking, Microsoft 365 co-editing and Google Workspace integration. Enterprise Lite at $39 adds ransomware detection, suspicious login detection, content lifecycle management and advanced workflows. Elite at $48 brings AI Assistant, AI Search, AI workflows, PDF markup, e-signature and dynamic watermarking, and Ultimate adds sensitive data classification and DLP integrations. Add-ons cover construction and large BIM files. The trade-off is cost and complexity: it is the most expensive starting price on this list, and the security features many buyers want sit two tiers up. For firms with project files and compliance needs it does more than general storage tools.

pCloud Business keeps team storage simple. The base plan covers 3 users with 3 TB of storage, and admins can assign custom quotas from the shared pool, group employees into teams, set access levels on shared folders and view activity logs per user and team. Files can be restored for up to 180 days, uploads have no file size limit, and the pCloud drive app lets staff work on files without using local disk space. Client-side encryption is available for files that need extra privacy, and pDocs adds six online editors for real-time collaboration. Shared links can carry your logo, cover image and message. pCloud is GDPR compliant and ISO 27001 certified and offers a 30 day free trial. It lacks the deeper governance, SSO and compliance options of Box or Egnyte, and the page we fetched showed euro prices, so its USD price is pending.

ShareFile is built for firms whose files mostly move between staff and clients. The Advanced plan costs $16.50 per user per month billed annually with a minimum of 3 users and covers encrypted storage and sharing, secure email integrations, real-time co-editing, granular access controls and basic reporting. Premium at $26 adds the client side: a portal, e-signatures, document requests, tasks, forms and workflow automation, with support for HIPAA, FINRA and SEC compliance and AI document generation. Enterprise automates user provisioning and adds data loss protection and activity monitoring, and a separate Virtual Data Room plan handles audits, litigation and deals with watermarking and NDA enforcement. For accountants collecting tax documents or lawyers exchanging case files, that saves a separate portal and signature tool. For a team that mainly wants internal storage, it costs more than Microsoft, Google or Sync.com and puts its best features on Premium.

Tresorit pairs end-to-end encryption with the admin and identity features that many encrypted tools leave out. The Business plan starts at 3 users and 6 TB of encrypted storage, or 2 TB per user, with a 15GB maximum file size, encrypted file sharing and requests, Office editing, data residency options, custom admin policies, single sign-on, domain verification and file locking for edits. Business Pro needs at least 5 users and adds 15 TB of storage, dynamic watermarks, link tracking and document analytics, auto-deletion policies, Azure AD and Okta provisioning, Active Directory support and a Microsoft Sentinel connector. Every plan includes 16 free eSignatures and trial data rooms for sharing with clients. Tresorit says more than 11,000 organizations use it. The cost of this depth is a slower setup than Sync.com or pCloud and a higher minimum seat count for Business Pro, and its pricing page did not show us USD prices.
