ShareFile vs Onehub vs Clinked: Best Secure Client Portals

Every client portal is an external entry point. It holds contracts, financial records and identity documents, and it hands logins to people outside your directory. When a portal is misconfigured, the exposure looks a lot like a supplier breach.

SecuritySenses has covered how data governance has become a defense against ransomware in healthcare, where third-party connections widen the attack surface. A file-sharing portal is one of those connections. This comparison looks at ShareFile, Onehub and Clinked through a security buyer's lens, using each vendor's own plan and security pages.

What Makes a Client Portal Secure Enough for Regulated Work?

Encryption is the baseline, not the differentiator. The controls that separate products sit around identity, scope and evidence.

A useful checklist for any portal review:

• Access scoping. Can permissions be set at the workspace, folder and file level?
• Enforced MFA. Can admins require a second factor, or only offer it?
• Single sign-on. Does staff access run through your identity provider?
• Audit trail. Is every view, download and share logged and exportable?
• Data residency. Can you choose where files are stored?

These map to zero trust thinking. The federal zero trust guidance on IDManagement.gov treats identity as a core pillar and stresses phishing-resistant authentication and least-privilege authorization. A portal that cannot enforce those for outside users pushes the risk back onto your team.

Offboarding is the control most teams forget. Client staff change jobs, and their portal access often outlives the engagement. A quarterly review of external accounts closes that gap. So does a rule that every engagement ends with a documented access removal.

Head-to-Head Comparison Table

Security Controls by Vendor

The sections below cover what each vendor states on its own site. Nothing here reflects an independent audit.

ShareFile

ShareFile is a secure file sharing and document workflow platform aimed at accounting, legal, finance and healthcare firms. Its security pages describe MFA and single sign-on, email file encryption from Outlook or Gmail, and granular access controls. Detailed user and file activity logs support audits and governance reviews.

Advanced includes a basic client portal for file and folder access. Premium adds the enhanced portal, e-signature, document requests and workflow automation. It also states support for HIPAA, FINRA and SEC regulatory compliance. Enterprise adds automated user provisioning, data loss protection and links to security monitoring tools.

Best For: Regulated firms that want secure exchange, e-signature and client workflows from one vendor.

Pricing: Advanced starts at $16.50 per user per month billed yearly, with a 3-user minimum. Premium carries the enhanced client portal, and a Virtual Data Room tier serves audits and M&A.

Standout Feature: Compliance support for HIPAA, SEC and FINRA workflows, backed by detailed activity logs.

Limitation: Per-user pricing with a minimum seat count adds up quickly, and the client portal features sit above the entry tier.

Onehub

Onehub is a cloud storage and virtual data room service built around shared workspaces. Its security page describes 256-bit encryption in transit and at rest, encrypted backups and integrity checks. Data is hosted through Amazon Web Services, which Onehub says carries SSAE 16 certification and PCI DSS Level 1.

Permissions are role-based at the workspace, folder or file level. Viewers, printers and downloaders count as free users up to the plan limit, which keeps client access cheap. The Data Room Edition adds watermarks, NDAs and a stealth mode for sensitive deals.

Best For: Teams that want fine-grained file permissions without a long rollout.

Pricing: Standard starts at $12.50 per user per month billed yearly, from 3 paid users. Advanced adds audit trails and enforced two-factor sign-in. Enterprise is quoted by usage.

Standout Feature: File-level role-based permissions, with most external client roles free up to the user limit.

Limitation: Audit trails, enforced two-factor sign-in and session timeouts are not on Standard. White label costs a $100 monthly add-on on Advanced.

Clinked

Clinked is a client portal and virtual data room provider that markets to accounting, legal, finance and government teams. Its pricing page lists ISO 27001, GDPR, G-Cloud and Cyber Essentials, along with SSL and at-rest encryption. The security standards page also cites GDPR-compliant privacy controls and AWS-hosted infrastructure.

Controls scale by plan. Every plan carries an audit trail, because Start Up includes all Standard features except a custom URL. Premium enforces two-factor sign-in with role-based permissions. Enterprise adds Active Directory, single sign-on, uptime SLAs and a choice of data center region. FISMA, FIPS, HIPAA, SAS70 and PCI coverage is listed as an add-on.

Best For: Organizations that need named certifications and control over where data lives.

Pricing: Start Up is billed per user. Standard, Premium and Enterprise follow, and the data room product is quoted separately.

Standout Feature: Regional data center choice across the US, EU and rest of world on Enterprise.

Limitation: Single sign-on and data residency sit on Enterprise, and regulated-industry coverage beyond the base certifications is an extra.

Where Do the Plans Draw the Line for Security Features?

The entry price rarely buys the controls a security team expects. Before you compare headline prices, check the tier where each control first appears:

1. Audit trail. Clinked includes it on every plan, Start Up included. Onehub starts on Advanced. ShareFile lists basic reporting on Advanced and detailed activity logs in its compliance features.
2. Enforced MFA. Onehub and Clinked both reserve enforcement for the second paid tier.
3. Single sign-on. Clinked keeps it on Enterprise. ShareFile lists MFA and SSO among its sign-in features.
4. Data residency. Only Clinked advertises a regional choice, on Enterprise.

The pattern holds across all three vendors, with one exception: Clinked puts its audit trail on every plan. Baseline encryption comes with every plan, while enforcement, evidence and identity integration cost more. Budget for the tier that carries the controls your auditors will test, not the tier on the banner.

How to Choose: Which Risk Profile Matches Your Data?

Start from the data, not the vendor. Classify what clients will upload, then match the portal to that class.

For health records or financial filings, look for a vendor that names the framework you answer to. ShareFile names HIPAA, SEC and FINRA on Premium. Onehub describes HIPAA compliance protocols. Clinked offers HIPAA as an add-on.

For cross-border work, residency may decide it. EU clients may require EU storage, which points to an Enterprise conversation with Clinked. For a small team sharing project files, Onehub's file-level roles may be enough.

Run a short proof of concept before signing. Invite two test clients, apply your intended permissions and try to reach a folder you should not see. Export the audit log and check that it records each view and download with a timestamp and user. Then disable one account and confirm access stops at once. Twenty minutes of testing often exposes gaps a sales demo will not.

Identity should weigh heavily for every buyer. SecuritySenses notes how AI agents are rewriting the rules of identity security. Portals now receive automated access too, so least privilege and access reviews matter more each year.

Alternatives to Consider

Not every client portal is a regulated document exchange. Service agencies often need a portal to sell and deliver work, with file sharing as one part of it.

Wayfront is one alternative in that space. It is client portal software for agencies that sell productized services, and it was known as Service Provider Pro until 2026. It combines checkout, intake forms, projects, a helpdesk and invoicing on one client record, with role-based permissions and a custom domain. Its site describes industry-standard security measures, encrypted database backups to multiple locations and 24/7 uptime monitoring. It does not list the compliance certifications that the three vendors above advertise, so it suits agency operations better than regulated records.

Frequently Asked Questions

Does Every Plan Include an Audit Trail?

No. Every Clinked plan includes one, while Onehub adds it from Advanced. ShareFile describes detailed user and file activity logs and admin reports in its compliance features.

Can I Force Clients to Use Two-Factor Authentication?

Yes, on the right plan. Onehub enforces it from Advanced and Clinked from Premium. ShareFile lists MFA and single sign-on among its sign-in controls.

Does Vendor Hosting With AWS Make a Portal Compliant?

Not by itself. Hosting certifications cover the infrastructure, not your configuration. The SANS glossary of security terms is a useful reference when mapping vendor claims to your own controls.

Should External Users Get Their Own Accounts?

Usually, yes. Named accounts give you a clean audit trail and let you revoke access per person. Shared logins break both, and they make incident response slower.
