What if my confidential email or data is compromised?

Not all data is created equal. Some information is intended for a very restricted audience only. Examples include legally binding contracts, HR information, financial data, medical records and government secrets. 

This is at the core of Secure Information Sharing (SIS).

With Deltagon Suite, your critical emails and data are protected with a high level of security and encryption that also meets strict regulatory requirements, like GDPR.​

We ensure that:

  • you can have secure confidential communications in internal networks with end-to-end encryption regardless of the environment or client/server configurations 
  • you share files, send emails, collect data with forms and sign documents as easily as before - just more securely and with robust encryption
  • you don't expose sensitive data to the public cloud or third party service providers
