Secure File Sharing for Businesses

Business file sharing usually means "let's pay Dropbox Business and call it secure." Then the company stores contracts, salary spreadsheets, client lists, and unreleased IP on a vendor that holds the keys and reads the content for "service improvement." It's not really secure. It just feels official.

A different approach: only share with services that mathematically cannot read your files.

What businesses actually need to share securely

Most company file transfers fall into a small number of categories:

• Contracts and NDAs — between legal teams, with clients, with vendors.
• Financial records — payroll spreadsheets, tax returns, invoices.
• Customer PII — KYC documents, ID scans, application forms.
• Internal designs and IP — pre-release products, source code, brand assets.
• Audit material — anything going to or from external auditors.

Every item on that list should be end-to-end encrypted in transit. None of it should be sitting on a vendor's disk in readable form.

Why "enterprise" file-sharing usually isn't enough

Dropbox Business, Box, OneDrive for Business — all encrypt at rest. None do end-to-end. Their security marketing is real (SOC 2, ISO 27001, the works) but it's all about how well they protect their custody of your data. They don't remove themselves from custody.

The practical implications:

• Their staff can access your files.
• A breach at their company exposes your plaintext.
• They cooperate with legal process — including foreign governments under MLATs.
• Their content scanning produces internal metadata about your files.
• Their AI features (recently) may train on your content.

The compliance angle

Regulators increasingly distinguish between "the vendor has the keys" and "the vendor cannot access content":

• GDPR. Personal data must be protected with "appropriate measures." Zero-knowledge architecture is the strongest possible measure — and it eliminates many breach-notification headaches because the data the vendor holds is mathematically unreadable.
• HIPAA. "Encryption is addressable" — strong client-side encryption simplifies a lot of BAA conversations.
• Schrems II / data localization. If the data crossing borders is unreadable ciphertext, the legal posture is different than if it's plaintext.

Be careful with this framing — none of it is a substitute for legal advice. But the practical fact is that strong E2EE simplifies more compliance conversations than it complicates.

Practical workflows for a business

Sending contracts to clients

Generate the document. Upload to Zippd. Send the share URL through your normal channel. The recipient opens the link, downloads, signs. The link auto-expires in 30 days — long enough for a real signing window, short enough that stale copies don't linger.

Receiving KYC documents from customers

Send the customer a Zippd link to upload to your account (feature coming). The document is encrypted on their browser, lands as ciphertext on storage, and you decrypt locally when reviewing. The PII never sits on Zippd's servers in readable form.

Sharing payroll spreadsheets internally

Upload from finance. Send the URL through the corporate Slack or email. Set a 1-week expiry and a download cap of N (where N = number of people who should see it). Once everyone's pulled their copy, the link dies.

Distributing pre-release builds to QA

Upload the build (often multi-GB — fine, Zippd handles 20 GB free). Send the link to QA. They download, test, and the link expires. No build artifacts accumulating in long-term storage.

Compared to enterprise alternatives

Where Dropbox/Box still win: deep ecosystem integration, SSO, audit logs that satisfy compliance auditors. For pure file transfer with privacy as the priority, Zippd does more for less.

Anti-abuse: what businesses care about

Two concerns that come up a lot:

• "Will our employees upload company secrets and walk away?" File transfer can't prevent insider exfiltration regardless of vendor. Either way the file leaves the corporate perimeter. The mitigation is HR policy + DLP at the network egress, not vendor choice.
• "How do we prevent vendor-side leaks?" Use a vendor that cannot read your files. Zippd's design eliminates the possibility of vendor-side plaintext leaks entirely.

FAQ

Does Zippd offer a business plan?

Currently free for all users. Custom enterprise features (SSO, audit log retention, longer expiry) are in roadmap. Contact us if you need them now.

Can I self-host Zippd?

Not officially supported today. The architecture is straightforward enough that a self-hosted variant is feasible for organizations that need it.

What about compliance certifications?

Zippd's architecture is designed with privacy-by-design principles that simplify compliance, but we don't yet have formal SOC 2 or ISO 27001 attestations. The cryptographic guarantees are stronger than what most certifications require — they just require independent audit to formally claim.

Can a manager see what employees have shared?

Not via our system. Each user's dashboard shows their own files. Multi-user team management is a roadmap item.
