Protect your company email accounts and messages

Sender confirmation and message encryption with S/MIME Certificates

Actalis offers S/MIME certificates that are recognized on the most popular platforms and compatible with all the main S/MIME-compliant email applications, such as Microsoft Outlook, Mozilla Thunderbird, Exchange, Gmail, and many others.

The benefits of Actalis S/MIME Certificates

In addition to a free version of the certificate, valid for an individual email address, Actalis also offers a corporate version of S/MIME Certificates, which contain data that strengthens brand awareness of the organization. Thanks to these certificates, emails are made truly secure, irrespective of the features of the email service being used.

  • Confidentiality - the message sent is encrypted and cannot be intercepted by malicious parties as it can only be decrypted, and so read, by the recipient.
  • Authenticity and integrity - the message is digitally signed and the recipient can check to make sure that the sender is really the one displayed, and whether the message has been altered.
