Encrypted.In the browser.For every recipient.
When the recipient has neither S/MIME nor PGP: The Conbool Secure Message Portal enables encrypted communication via a secure web portal. With reply functionality.
Secure Message Portal: Encrypted Emails for Every Recipient
The Conbool Secure Message Portal is the secure fallback when your recipient doesn't have encryption certificates. Confidential messages are delivered, read, and replied to via a protected web portal.
Why a Secure Message Portal?
Not everyone has encryption
Only a fraction of all email users have S/MIME certificates or PGP keys. Yet you still need to communicate confidentially.
PDF isn't always enough
PDF encryption is good for one-way communication. But what if the recipient needs to reply?
Email is insecure
Standard email is transmitted in plain text. Without encryption, third parties can read along.
Compliance demands it
GDPR, NIS2, and industry-specific regulations require encrypted communication for sensitive data.
How the Secure Message Portal works
Three simple steps. No setup, no software, no keys.
You send an email
Write your email as usual. Conbool automatically detects when encryption is required.
Portal notification
The recipient receives a notification with a secure link to the Conbool Portal. The actual message stays protected.
Read and reply
After one-time registration, the recipient can read the message in the browser, download attachments, and reply encrypted.
What the Secure Message Portal offers
More than a simple web portal. A full-featured encrypted communication platform.
End-to-end Encryption
Messages are encrypted with TLS and AES. Neither Conbool nor third parties can read the content.
Reply Functionality
The recipient can reply encrypted directly in the portal. No separate email encryption needed.
File Attachment Support
Send and receive encrypted attachments of any size. Ideal for contracts, invoices, and sensitive documents.
Custom Branding
The portal can be customized with your logo, colors, and domain. Professional appearance to your recipients.
Automatic Fallback
Conbool checks S/MIME first, then PGP, then TLS. The portal is the intelligent fallback when no standard is available.
Delivery Confirmation
See if and when the recipient opened the message. Verifiable for audits and compliance.
