Confidencial for Outlook

A safer way to send sensitive data from Outlook.

Protect files and messages the moment you send them. Then see who opens them, and revoke access at any time. No new tools for employees, and no account for recipients.

The problem with sending sensitive email

Warning or blocking isn't protection. Sensitive data needs protecting as it's sent, and control after.

Security tools can warn employees or block the email, but neither protects what actually gets sent. The content leaves unprotected, and once it's gone you can't see who opens it or take it back.

WITHOUT CONFIDENCIAL

The result?

Security knows what's sensitive, but can't always protect it where business actually happens.

WITH CONFIDENCIAL

A protected way to send what policy flags.

The email carries a secure link, not the content. Access stays tracked after it leaves. Recipients need no account or software.

Key capabilities

Built for security. Designed for how people work.

One-click protected sending

Protect attachments and message content without leaving Outlook.

Persistent access control

See when recipients open protected content, and revoke access at any time. Every send appears in the same history as the Confidencial web and desktop apps.

No sensitive copies left behind

No unprotected copy stays in Sent Items.

Works for every recipient

Send to internal and external recipients in one email. It comes from your own address, and replies come straight back to you.

Your keys, your storage

Keys stay in your own key management system, and protected files stay in your own storage. Confidencial does not host them.

Admin-set protection policies

Templates apply encrypted-download only, forwarding limits, expiry dates, and watermarks to every send automatically.

Better together: Microsoft Purview + Confidencial

Purview labels sensitive data. Confidencial for Outlook protects it when it's sent.

Purview identifies and labels sensitive data, then warns or blocks when someone tries to send it. Confidencial for Outlook adds a third option: send it protected.

Use your existing labels

Recognizes Purview sensitivity labels in Outlook.

Send flagged information safely

A protected option when policy blocks normal email.

Keep control after external sharing

Track and revoke access outside your organization.

Confidencial for Outlook in the wild

Common situations where sensitive email needs protection

Misdirected email

The wrong recipient.

Autocomplete picks the wrong name, and a client file goes to someone outside the deal.

With Confidencial

Revoke access in one action. The recipient can't open anything they haven't already opened.

Client_Agreement_Confidential.pdfAccess revoked
Legal and M&A

The sensitive deal.

Financials and term sheets go to bidders and advisors. A bidder who drops out still has copies.

With Confidencial

Every file stays encrypted, and you can revoke access when the process ends.

Purchase_Agreement_Draft.docxAccess tracked
Financial services

The regulated workflow.

Customer, financial, or personal data has to reach a third party, and policy blocks the email.

With Confidencial

Employees send it with protection instead of looking for a way around the policy.

Account compromise

The compromised mailbox.

An attacker gains access to an employee's email account and searches Sent Items for confidential attachments.

With Confidencial

The sent email holds a secure link, not the files, so a compromised mailbox doesn't expose them.

Frequently asked questions

What security teams ask us first

Does Confidencial for Outlook replace Microsoft Purview?

No. It recognizes Purview sensitivity labels and gives employees a protected way to send labeled content, including when policy would block the email.

Does the recipient need a Confidencial account?

No. External recipients open protected content through a secure link and verify with a one-time code. Internal recipients sign in with their usual account. No special software is needed.

Can I revoke access after an email is sent?

Yes, for content sent using Protect and Send. Senders can revoke future access to the protected message and attachments. Revocation cannot undo information a recipient has already viewed or copied outside the protected experience.

Does it protect the subject line?

No. Confidencial for Outlook protects attachments and message content. Keep sensitive details out of the subject line.

Does it require changes to Microsoft Exchange?

No. Confidencial for Outlook works as an add-in and does not require changes to Exchange infrastructure or mail flow.

Does Confidencial automatically detect sensitive content?

Today, users initiate protection by selecting Protect and Send. Policy-based detection and recommendations or enforcement are planned capabilities.

How is Confidencial for Outlook deployed?

It installs from Microsoft's Outlook add-in store. Users can add it themselves, or IT can deploy it centrally to everyone.

Where are protected files stored?

In your own storage. Confidencial connects to the storage you choose and does not host your files on its own cloud.
