How to send secure emails

Send confidential information and sensitive personal data via email by using the Sikker@Mail plugin. Sikker@Mail encrypts and digitally signs your emails. 

  • The encryption ensures that only the recipient can read the email. 
  • The digital signature ensures that the sender is the person they claim to be and that the content is the same as when it left the sender.
