Robust security

Secure Mail offers various user authentication options, such as passwords, SMS, MFA, and more.

Your communications are protected with encryption from sender to recipient. Secure Mail supports various email security protocols (DMARC, DKIM, SPF) as well as S/MIME based encryption.


Data privacy compliance

Secure Mail makes sending and receiving sensitive information easy. Sensitive data is protected by robust encryption and your business stays compliant with data privacy laws and regulations (e.g. GDPR).


Customizable data classification

With Secure Mail, you can classify confidential information and adjust security levels according to your policies. You can apply extra security layers (like MFA) when needed.


Automatic scanning for your email traffic

Secure Mail automatically scans and analyzes your email traffic and recognizes confidential information. Based on your policy, you can automatically encrypt such emails or prevent them from being sent.


Flexible deployment

You are in control of your data - deployment is possible in the cloud or on-premises. Secure Mail offers multiple configuration options (APIs, web interfaces).

Sending unencrypted emails is like sending
confidential information on a postcard

  1. Email is still the most commonly used tool for business communications because of its ease of use and accessibility, regardless of the security limitations of the Simple Mail Transfer Protocol (SMTP) protocol - the standard communication protocol for electronic mail transmission. 
  2. Many webmail solutions have native encryption, but the communications can still become unencrypted on their way to the recipient, making them vulnerable to misuse.
  3. Traditional Transport Layer Security (TLS) is a cryptographic protocol providing communications security over a computer network. However, it often lacks complete end-to-end encryption.
