Trend Micro Email Encryption - license

Trend Micro Email Encryption enables organizations to enforce compliance requirements and to ensure that confidential information is delivered securely. Trend Micro's Private Post technology, developed by cryptographers at the University of Bristol, uses identity-based encryption (IBE) to avoid the burdensome pre-registration and certificate management of earlier Public Key Infrastructure (PKI) technology. Encrypted content is simply pushed from senders to recipients like any other email.
