10 secure file sharing platforms compared

1. LiveDocument

LiveDocument is my pick when a document needs to do more than sit in a folder. It turns PDFs, slide decks, images and web documents into a single browser-based experience, with a short video walkthrough alongside the pages. You share one public or private URL, and the recipient doesn't need to install anything.

That changes the job from "please review this attachment" to "here's the document, and here's the explanation I'd normally give you on a call". For sales proposals, consultant reports, legal documents, property information and investor decks, that distinction matters. The recipient can hear the context while reading, rather than guessing which pages deserve attention.

2. Box

Box is the stronger choice when the file itself is the centre of the workflow. It's an established enterprise content cloud with granular permissions, external links, governance controls and a broad integration ecosystem. If your organisation already works across Microsoft 365, Google Workspace and Salesforce, Box can give teams a common place to manage business content without forcing every process into email.

External links can be protected with passwords and expiry controls, while administrators can apply governance, classification and legal-hold policies through the relevant plans and add-ons. Box also offers native e-signature and a Trust Center for its compliance documentation.

The strength is administrative depth. Security teams get more than a simple share button, and business teams get a familiar way to collaborate with external recipients. A guide to sharing files with external users is useful background, but Box is the better fit when external access must sit inside a wider content-management policy.

The weakness is complexity. Small teams may spend more time configuring permissions, governance modules and integrations than they expected. Advanced requirements can also push costs upwards, so check the exact package rather than assuming the base plan includes every control.

Box is excellent at controlling content across an organisation. It isn't built primarily to show which page of a proposal a buyer read or to attach a narrated explanation to each document.

Best for: regulated organisations that need mature content governance and broad integrations.

3. Dropbox Business

Dropbox Business wins on familiarity. Most recipients understand how Dropbox links work, and that low external friction can be valuable when you're sending files to people who don't want another account or complicated portal.

Business plans provide link controls, including passwords and expiry settings, alongside file requests, version history and smart sync. Teams also get a central admin console, audit logs, SSO and SCIM support, with additional capabilities available through the wider Dropbox ecosystem.

That makes Dropbox a practical option for everyday business sharing. Desktop clients are strong, the user experience is recognisable and recipients can usually access a shared file without installing anything. It's a sensible choice for teams that need controlled sharing but don't want to retrain everyone around a specialist platform.

The compromise is governance depth. Dropbox can cover common business requirements, but teams with demanding classification, DLP or retention needs may find that a content-security-first platform offers more control. Storage and plan details also vary, so review the exact regional offer before you commit.

Dropbox tells you about file activity. It won't give you the same document-engagement view as LiveDocument, where page-level behaviour and narrated walkthroughs shape the follow-up.

Best for: businesses that prioritise familiar, low-friction file sharing.

4. Microsoft OneDrive for Business

If your organisation already runs on Microsoft 365, OneDrive for Business is the default decision. Files sit close to SharePoint, Teams and Office, and users can collaborate within the tools they already open every day.

OneDrive supports internal and external link sharing with controls such as passwords and expiry options. Microsoft Purview adds DLP and information-rights management capabilities, while administration and auditability connect with the wider Microsoft 365 environment. That integration is the main reason to choose it. You avoid creating another storage island and can apply identity and compliance policies through an existing Microsoft stack.

5. Egnyte

Egnyte is for teams that need file sharing tied closely to governance. It combines external sharing with content classification, risk policies, DLP and audit-readiness features, making it a strong option for regulated industries where administrators need to understand what data exists and how people use it.

Its hybrid deployment model is a major differentiator. Organisations with data-residency or performance requirements can use a structure that combines cloud access with more controlled storage arrangements. That makes Egnyte particularly relevant to sectors such as professional services, life sciences and financial services.

The product's value appears when policy matters more than presentation. You can set rules around content, apply controls to shared links and retain records for investigation or audit work. Egnyte also has strong compliance documentation across frameworks including HIPAA, GDPR, SEC and FINRA, ISO and SOC 2.

The cost is operational effort. Smaller teams may find governance configuration heavy, especially if they only need to send a few confidential documents each week. Advanced modules can also change the commercial calculation.

Egnyte is a serious governance platform. It won't turn a static proposal into a guided experience or tell you which page made a recipient pause.

Best for: regulated teams that need content intelligence, policy controls and hybrid deployment options.

6. Citrix ShareFile

Citrix ShareFile, now part of Progress, is built around client collaboration rather than generic cloud storage. That makes it a natural fit for professional services, legal, real estate and healthcare teams exchanging documents with clients.

The platform provides branded client portals, large-file transfer, password and expiry controls, granular permissions, workflow automation and integrated e-signature. The portal model is useful when the relationship needs a polished, repeatable place for clients to upload, review and return documents.

HIPAA enablement is available with a signed BAA on eligible plans. That qualifier matters. Don't treat the product name alone as proof that your account, configuration or workflow meets your obligations. Confirm the precise tier and contract terms before sharing protected health information.

ShareFile's main advantage is structure. A portal can feel more deliberate than a loose collection of email attachments, especially when several documents and approvals are involved. Its limitation is that the interface is designed around portals and workflows, not deep document engagement analytics.

If your question is "can the client access and return these files securely?", ShareFile is a strong candidate. If the question is "which pages did the client read before our meeting?", LiveDocument is closer to the problem.

Best for: client portals, large-file exchange and professional-service workflows.

7. Tresorit

Tresorit takes the privacy-first route. Its zero-knowledge, end-to-end encrypted storage and sharing model is designed for teams that don't want the provider able to access the contents of their files.

That architecture suits privacy-sensitive work in health, legal and finance environments. Business plans include link controls, administrative features, SSO and data-residency options, with integrations and add-ons for email, e-signature, Outlook, Teams and Gmail.

Tresorit is a good answer when confidentiality is the central concern. Cross-platform apps help people work across devices, while encrypted links can reduce the temptation to send sensitive material through ordinary email.

The trade-off is friction. End-to-end encryption can make some collaboration patterns less convenient, and the product is typically more expensive than mainstream cloud storage. Business plans also have a three-user minimum, which is a meaningful constraint for a solo operator or very small practice.

Tresorit protects the contents of the handoff exceptionally well. It doesn't focus on helping a sender understand which section of a proposal created interest or whether a recipient watched an explanation.

Best for: privacy-sensitive teams that prioritise zero-knowledge encryption over broad collaboration convenience.

8. Sync.com

Sync.com offers privacy-led file sharing with a more accessible small-business posture. It provides end-to-end encrypted storage and sharing, password and expiry links, file requests and granular user policies. Eligible business tiers also support HIPAA arrangements through a BAA, alongside compliance positioning for GDPR and PIPEDA.

That combination makes Sync.com attractive to smaller teams that want stronger privacy controls without buying an enterprise content-governance suite. Version and retention features can support longer-running client work, although availability depends on the plan.

The user experience is straightforward. You can create a controlled link, request files from an external party and manage team access without building a complex portal. For ordinary confidential documents, that's often enough.

The limitation is reporting and administration. Sync.com doesn't match the depth of the largest enterprise ecosystems, and its product development pace is less expansive than the major productivity-suite vendors. That's acceptable if your requirements are clear. It becomes a problem when you expect advanced DLP, extensive integrations or detailed operational reporting.

Sync.com is a storage and privacy decision. It isn't a document-sales or document-explanation platform.

Best for: small and mid-sized teams that want encrypted sharing with clear privacy positioning.

See Sync.com business pricing

9. Kiteworks

Kiteworks is the heavy-duty option on this list. It combines secure file sharing with managed file transfer, SFTP, secure email, web forms and virtual data room capabilities, giving highly regulated organisations one governed environment for sensitive exchanges.

Detailed audit trails and policy controls are central to the product. That matters when an organisation needs durable evidence of who accessed, shared or transferred information, rather than a basic record that a link was created. Kiteworks also publishes extensive certification and authorisation resources, including SOC 2, ISO 27001 and FedRAMP Moderate.

The platform is designed for government, defence, financial services and healthcare use cases where compliance and central control dominate the buying decision. Managed transfer support also makes it more suitable than ordinary cloud storage for repeatable system-to-system workflows.

The downside is obvious. Kiteworks is too complex for a founder who needs to send a proposal securely. Public pricing is limited, and larger deployments are sales-assisted. You're buying a governed data-exchange platform, not a lightweight sharing link.

For a regulated enterprise, that complexity can be justified. For a sales team measuring proposal engagement, it's the wrong centre of gravity.

Best for: enterprises that need secure sharing, managed transfer and detailed governance in one system.

10. Proton Drive for Business

Proton Drive for Business brings Proton's privacy model to business file storage and sharing. It uses end-to-end encryption for files and metadata, supports password and expiry links, and includes team management, role-based access controls and an administrator console.

Cross-platform apps cover web, Windows, macOS, iOS and Android. That breadth makes Proton Drive approachable for smaller teams that want private storage without adopting a large enterprise content suite.

The business plans are simple enough for teams that value privacy and don't need an elaborate governance stack. Proton's reputation also gives the security model a clear identity, which can help when your customers ask where sensitive files are stored and who can access them.

The limitation is maturity around enterprise administration and integrations. DLP, advanced reporting and complex workflow requirements need careful validation before you commit. The feature set is evolving, so test the exact business functions your team depends on rather than relying on the privacy headline alone.

Proton Drive is compelling for encrypted storage. It won't replace a client portal, managed file transfer service or engagement platform.

Best for: smaller teams that want a privacy-first, end-to-end encrypted storage service.

How the ten platforms compare

Choose the platform that matches the handoff

Start with the handoff, not the vendor list. Secure storage answers whether a file is protected before and during access. Document engagement answers what happens after someone opens the link. Those are separate tests, and choosing the wrong one leaves a gap between safe delivery and useful follow-up.

Choose LiveDocument when you are explaining and measuring a proposal, report, deck or other document. Its value begins after the link opens, with narration, real-time alerts, page-level analytics and optional email gating. Review its security details, confirm how recipients are identified, and compare the pricing before adding its engagement layer to your existing storage setup.

Choose Box, Egnyte or Kiteworks when governance, audit controls, retention and policy enforcement lead the decision. Choose Microsoft OneDrive when your organisation already runs on Microsoft 365 and needs sharing inside that identity and compliance environment. Choose Dropbox Business when recipient familiarity and low-friction sharing matter more than specialist governance.

Choose Citrix ShareFile for branded client portals and document workflows. Choose Tresorit, Sync.com or Proton Drive when privacy-led encrypted storage is the primary requirement. These platforms protect files and control access, but they do not all provide the same visibility into page-by-page engagement after opening.

Test the actual handoff before buying:

• Classify the files: Decide whether you are sharing ordinary business documents, personal data, health information, contractual material or highly restricted content.
• Check recipient friction: Confirm whether external recipients need accounts, passwords, software or a portal invitation.
• Test link controls: Create links, change permissions, test expiry and revoke access. Verify the result instead of trusting the policy description.
• Confirm the compliance plan: Check the exact subscription, BAA, audit features, residency options and configuration required for your workload.
• Separate protection from visibility: Encryption protects files during storage and transfer. Alerts and analytics show what happened after access.
• Decide on identity: If anonymous sharing complicates follow-up, check whether email gating can identify viewers before they open the document.

The compliance question requires precision. CNIL guidance recommends a protocol that protects confidentiality and authenticates the destination server, such as SFTP or HTTPS, when personal data travels across a network. It also says secrets such as passwords or encryption keys should be sent through a separate channel from the protected file, as described in its personal data security guidance.

HIPAA workflows need more than a padlock icon. The relevant guidance points to encryption before ePHI leaves the originating system, audit controls for reads, downloads and shares, immutable or append-only logs, role-based access control and MFA for privileged actions. Include those controls in the HIPAA security review rather than treating them as a procurement checkbox.

Secure file sharing is now a serious enterprise category, not a checkbox feature bolted onto storage. More storage does not automatically create better communication.

Match the platform to the risk and the moment. For a regulated archive, buy governance. For transfers between systems, buy managed transfer. For a proposal that recipients need to understand, buy visibility.
