How it works

SecuMailer sends all emails of its customers via an encrypted connection. This prevents data leakages and prevents confidential or personal data from being accessed by unauthorised entities. In less than a day your organisation can start sending secure emails via SecuMailer.

This is what happens when you send a secure email via SecuMailer

The sender creates the email and sends it from his existing email environment (for instance Outlook). The email is routed to the secure mailserver of SecuMailer. The email is further protected by adding a digital signature. After that SecuMailer verifies if the encryption is encrypted from sender to recipient and sends the email over the secure connection to the recipient. The complete interaction is documented in the audit log of SecuMailer and can serve as evidence for the secure delivery of every email.

The recipient receives the email in the inbox of his email environment.

Alternative secure delivery

In only 2-5% of the cases, an email cannot be securely delivered. After the e-mail is sent, the sender receives a message that the email cannot be delivered to the recipient. The sender is requested to enter the mobile phone number of the recipient. This is only required once.

The receipient receives a notification with a referral to the original message. If he clicks the link, he will go to the page on the website of the sender where SecuMailer presents the secure email. This page is fully customizable to the look and feel of the website. After the recipient enters the sms code that he just received on his mobile, he can read the email and/or download it to his email application.
