FOR THE TEAMS WHO HANDLE SENSITIVE FILES

Send, receive, and store sensitive files. Securely and easily.

Contracts, salary sheets, financial statements, client records, even passwords. Honeycake locks each file to the people you choose, so it stays protected in any inbox, shared drive, or laptop. Sent it to the wrong person? Take it back.

As easy as attaching a file. The people you send to just sign in with their email. Nothing to install.

SOUND FAMILIAR?

Sensitive files leave your hands every day.

Email, shared drives, chat, downloads. Once a file is sent, most tools can't tell you who has it, and can't get it back.

"I sent it to the wrong person."

With HoneycakeTake it back. Burn the file and it stops opening everywhere, even copies you never knew about.

"We keep four copies of the same spreadsheet."

With HoneycakeKeep one file. Each person sees only the columns or pages they are cleared for.

"Clients email us their tax returns and IDs."

With HoneycakeGive them a secure upload page. Files arrive protected, straight into your own storage.

"Someone left, with a laptop full of our files."

With HoneycakeRemove their access. The files they already have stop opening the next time they try.

"The auditor asked who saw it. We had no idea."

With HoneycakeSee every person who opened a file and when, plus everyone who tried and was blocked.

"The numbers got out before the announcement."

With HoneycakeSet the earliest moment a file can be opened. Until then, nobody can open it, wherever it ends up.

"Our passwords live in a spreadsheet and a chat thread."

With HoneycakeKeep them in a protected file that only the right people and systems can open.

"AI tools now read our inboxes and drives."

With HoneycakeA protected file stays unreadable to any person or tool you have not approved.

RECEIVE · STORE · SEND · REDACT

One way to protect a file, from the day it arrives.

Receive ORGANIZATIONS

Collect documents from clients, candidates, and vendors with a simple upload page. Each file is locked on the sender's computer, then lands in your Box, Dropbox, Google Drive, SharePoint, or S3.

About the Uploader →
Store

Keep files wherever you already do. A protected file stays protected in shared drives, backups, and laptops, and only opens for the people you chose.

How To guide →
Send

Send through Gmail, Outlook, Slack, or a download link. Change who can open it after it's sent, set an expiration date, or take it back entirely.

Email and sharing →
Redact

Stop making redacted copies. Send one file, and each person sees only the pages, columns, or sections they are cleared for.

About redaction →
REDACTION

One source of truth. Many views.

Mark the sensitive parts once. Honeycake shows each person only what they are allowed to see, from the same file. No second copy to drift out of date, and no second copy to leak.

  • Hide pages in a PDF, columns in a spreadsheet, slides in a deck, or sections of text.
  • Change who can see what, even after it's sent.
  • Need a normal PDF? Share one with black boxes for everyone, while the people you choose can still see the original.

BY TEAM

Built for the people who handle the sensitive stuff.

Legal
  • Send contracts and settlement drafts to outside counsel and clients who are not on your systems.
  • Hold a document until a set date and time, and have it stop opening when the matter closes.
  • One board pack where conflicted directors never see certain slides.
Board pack example →
HR
  • Share one compensation spreadsheet. Finance sees salaries, managers don't.
  • Collect offer letters, IDs, and tax forms from new hires without email attachments.
  • Keep investigation files openable only by the investigation team.
HR spreadsheet example →
Finance
  • Send forecasts and financial statements that can't be opened before the release date and time.
  • Collect W-9s, invoices, and bank letters from vendors with a secure upload page.
  • Give auditors access that ends when the audit does, and see exactly what they opened.
Release dates and expiration →
Compliance
  • Know who opened what, and when, for every file. Blocked attempts too.
  • Remove access the day someone leaves, from files they already have.
  • Set expiration dates so files don't outlive their purpose.

IT
  • Protect API keys, passwords, and certificates in a file only the right people and systems can open.
  • Keep secrets right next to the code in your repository. Your team and your build systems can read them; nobody else can.
  • Remove someone's access the day they leave. No separate vault service to run.

EASY ON PURPOSE

If security isn't easy, people go around it.

So Honeycake works the way your team already does. We call protecting a file Baking it.

1

Pick the file

Drag it into the Honeycake app, or attach it in Gmail or Outlook like any other email.

2

Choose who can open it

Type their email addresses, or allow everyone at your company. Add an expiration date if you like.

3

Send it any way you like

Email, Slack, a shared drive. They sign in with their email and it opens, in their browser or the free app.

WHY YOU CAN TRUST IT

Your files never touch our servers.

Files are locked and opened on your own devices. Honeycake only manages who is allowed to open what. We call this zero-exposure: there is no pile of your documents sitting with us.

Honeycake is built by a team with roughly 100 combined years in enterprise security and data systems. Our founder previously built Integral Ad Science (NASDAQ: IAS). Headquartered in Center City, Philadelphia.

"Honeycake gave us a way to automate data delivery securely. Something we couldn't do simply with other file-share platforms."

FOR YOUR SECURITY REVIEW

The details your security team will ask for: every file gets its own AES-256 encryption, done on the user's device. Single sign-on, groups, automatic folder protection, a command-line tool, and an API for automation.
